Description

Gas absorption device and use its vacuum insulation part
Technical field
The present invention relates to gas absorption device and use its vacuum insulation part.
Background technology
In recent years, from from the viewpoint of preventing global warming, also turn into tight for the energy-saving of household electricity gasification product Anxious problem.Particularly, for the insulation cold insulation equipment of refrigerator, refrigerator-freezer and automatic vending machine etc., from effectively utilizing heat From the viewpoint of, it is desirable to the heat-insulating material with excellent heat-insulating property.
As the heat insulating material with excellent heat-insulating property, it is proposed that vacuum insulation part.It is be processed to it is bag-shaped In laminated film (being hereinafter referred to as cladded with part) with gas barrier property, storage air phase volume ratio as mineral wool is high and constitutes thin The core in micro- space, by the insulation for depressurizing and seal and make core accommodation space.
In vacuum insulation part, by improving its internal vacuum, high performance heat-insulating property can be obtained.However, carrying Condition of high vacuum degree is subject to be present in hindering for the gas inside vacuum insulation part.It is present in the gas inside vacuum insulation part substantially may be used It is divided into following three kinds.One kind is, when vacuum insulation part is manufactured, not to be depressurized and be vented and the gas of remaining, and another kind is to subtract After press seal dress, and the gas that is produced by core and overcoating part (it is adsorbed in the gas of core and overcoating part, and it is not anti-due to core Gas answered composition to react and produce etc.), finally a kind of is by being cladded with part from the outside gas for invading.
It is also hermetically sealed together with core to have in the overcoating part of vacuum insulation part in order to these gas absorptions are removed Gas absorption device.
Gas absorption device by the filling gas adsorption piece in choke container, and choke container is carried out into Vacuum Package and Constitute (for example, referring to patent document 1).
Figure 21 is the figure of the composition for representing the existing gas absorption device 1100 described in patent document 1.
Existing gas absorption device 1100 is following composition：In vacuum or argon gas atmosphere, in the resistance of metal tub Filling gas adsorption piece 1102 in gas container 1101, under reduced pressure, is flowed into the glass encapsulation materials 1105 of melting and is arranged on Narrow 1104 at the opening 1103 of choke container 1101, is allowed to cool solidification.Thus, the opening 1103 of choke container 1101 It is packed.
In existing gas absorption device 1100, in the preservation before being applied to vacuum insulation part, due to choke container Gas absorption part 1102 in 1101 is isolated with outside atmosphere, it is possible to prevent the performance degradation of gas absorption part.In addition, When vacuum insulation part is applied to, external force, glass envelope are applied from the outer lateral choke container 1101 of the overcoating part of vacuum insulation part Package material 1105 is destroyed, and makes the inside and outside connection of choke container 1101.Thus, the absorption of gas absorption part 1102 is present in overcoating part Interior gas.
So, the gas in the overcoating part of vacuum insulation part is adsorbed by gas absorption device 1100 to keep vacuum, Vacuum insulation part can be made to play good heat-insulating property.
Existing gas absorption device 1100 is the narrow 1104 for making to be flowed into after glass melting choke container 1101, is melted Melt glass due to surface tension, and be detained in the inner surface of narrow 1104 and engage.Afterwards, it is maintained at narrow by making melten glass Cooled and solidified in the state of portion 1104, narrow 1104 is packaged.Accordingly, it would be desirable to be used to making melting and the cooling and solidifying of glass Time, so being difficult to improve productivity ratio.Meanwhile, in order to carry out the management of the melt viscosity of high-precision glass, it is necessary to it is special and Expensive vacuum heat treatment furnace etc..Thus there is a problem of that the cost reduction of gas absorption device 1100 is difficult.
In addition, in destroyed glass encapsulation materials 1105, via breach part, making choke container because applying external force Connected with the overcoating part of vacuum insulation part in 1101.Now, the breach of the inside and outside connection of choke container 1101 is made to produce, Need to make glass encapsulation materials 1105 turn into certain thickness piece.In addition, in order to ensure entering to gas absorption part 1102 Gas and the stream of the gas produced in activation that row is produced when heating, the encapsulation mouthful as choke container 1101 The opening of narrow 1104 need with a certain degree of cross-sectional area.From these viewpoints, it is also desirable to make narrow The glass encapsulation materials 1105 of 1104 melting encapsulation turn into the block with thickness to a certain degree.
Therefore, choke container 1101 will at least have the thickness and choke container 1101 of the block of glass encapsulation materials 1105 Thickness of slab part thickness, make thinner in the presence of limitation.
Further, gas absorption device 1100 is due to being the glass encapsulation materials 1105 of high temperature, choke with melt temperature Container 1101 is also required to be set to the raw material, for example metal by being resistant to high temperature, as rigid objects.It is thus impossible to Vacuum insulation part is deformed according to the shape of the equipment for being used, be there is also in flexibility limitation being made it have, also existed The confined problem of suitable device.
On the other hand, recently, improved with the heat-insulating property of vacuum insulation part, the requirement according to the equipment for being used is adiabatic Ability, thickness be several millimeters or so vacuum insulation part and be processed into curved or cylindrical shape, for example for hot water supply device etc. Vacuum insulation part be also commercialized.So require also be applied to the gas of the new vacuum insulation part being commercialized Body absorbing elements, its demand is constantly being highlighted.
Further, vacuum insulation part is from the heat-insulating material of the insulation cold insulation equipment such as refrigerator all the time to being used as in recent years The heat-insulating material of building materials and LNG ship etc., its purposes is constantly expanding.Therefore, for vacuum insulation part, it is also desirable to its own Maximization and can longer-term ground maintain high thermal insulation.Therefore, the loading for increasing gas absorption part also becomes class Topic.
However, in the case of the loading of increase gas absorption part, if the composition of existing gas absorption device 1100 If constant, heating the gas produced when the gas and activation that are produced during gas absorption part will become many, at heating Reason needs the substantial amounts of time, causes productivity ratio to reduce.
Make the filling quantitative change of gas absorption part many therefore, it is possible to not reduce productivity ratio, or it is large-duty same carrying When making to turn into problem the filling quantitative change of gas absorption part more.

The content of the invention
The present invention be in view of above-mentioned problem and carry out, it is high, thin and possess flexible and energy its object is to provide productivity ratio Enough increase gas absorption part loading, can maintain for a long time gas sorption ability gas absorption device and using its Vacuum insulation part.
Gas absorption device of the invention includes：Cladding bag with gas barrier property and flexibility, it is depressurized and is encapsulated in cladding bag Interior gas absorption part and the porous member configured with plane state and the adjoining of gas absorption part in the inside of cladding bag.
It should be noted that in the present invention, " with plane state and the porous portion of gas absorption part adjoining configuration Part " refers to that among the face for constituting porous member, the face beyond the maximum face of area is adjacent to configuration with gas absorption part.
" adjacent configuration " refers not only to gas absorption part and is adjacent to contact condition with porous member match somebody with somebody in addition, in the present invention Situation about putting, be also included between both across some parts, for example as illustrated in the 2nd implementation method across water adsorption Part etc. is adjacent to the situation of configuration.
In addition, in the invention, " shape " of porous member can also be, for example, the tabular of polyhedron or cylinder etc. Shape in addition.
Thus, after gas absorption device of the invention can be depressurized by using general vacuum extractor, pass through Thermal welding is manufactured.When decompression encapsulation is carried out in the cladding of gas absorption part bag to being inserted with, by lateral from porous member Gas absorption part side carries out suction decompression to cladding bag, and the gas absorption part in cladding bag, can due to the presence of porous member Prevent from being vented from cladding bag internal suction.Thereby, it is possible to be manufactured in the case where special device is not used, and, Neng Gou Decompression encapsulation is carried out while not slowing down vacuum pumping rate, it is possible to increase productivity ratio, inexpensively provided.
In addition, gas absorption part and porous member are abutted configuration in flexible cladding bag with plane state.By This, it is (maximum with gas absorption part and the respective area of porous member compared to the configuration that overlapped with porous member of gas absorption part The configuration of state that face contacts with each other) situation, thickness is thinner, and the deformation such as bending is also easier to, additionally it is possible to left suitable for several millimeters Right thin vacuum insulation part and bend to vacuum insulation part that arc-shaped is used etc..
And, by increasing the plane width of cladding bag, the amount of gas absorption part can be made while thickness of thin is kept Become many, can be made to maintain for a long time the material of gas sorption ability.I.e. it is capable to both realize for varied Vacuum insulation part application expand, gas sorption ability can be for a long time maintained again.
As described above, the present invention can be provided, productivity ratio is high, can inexpensively provide and due to thin and with flexible Diversified vacuum insulation part can be applied to, be further able to maintain for a long time the gas absorption device of gas sorption ability And use its vacuum insulation part.
1st mode of the invention is a kind of gas absorption device, and it includes：Cladding bag with gas barrier property and flexibility, quilt Gas absorption part and abutted with plane state and gas absorption part in the inside of cladding bag that decompression is encapsulated in cladding bag The porous member of configuration.
Thus, after the gas absorption device can be depressurized by using general vacuum extractor, thermal welding is carried out To manufacture.When will be inserted with decompression encapsulation in the cladding of gas absorption part bag, by from porous member lateral gas adsorption piece side Decompression will be aspirated in cladding bag, the gas absorption part in cladding bag is prevented from from cladding bag due to the presence of porous member Portion's pumping exhaust.Therefore, can just not manufactured using special device, can not become vacuum pumping rate slowly carries out decompression envelope Dress, can improve productivity ratio, inexpensively provide.
Further, since gas absorption part and porous member abut configuration in flexible cladding bag with plane state, So compared with the situation of configuration that gas absorption part and porous member overlap, can make thinner, and deform bending etc. Become easy.Thus, it is also possible to thin vacuum insulation part suitable for several millimeters or so and bend to that arc-shaped uses it is true Empty insulation etc..Further, the plane width of bag is coated by increasing, additionally it is possible to increase gas while thickness of thin is kept and inhale The amount of annex, can for a long time maintain gas sorption ability.
Next, the 2nd mode of the invention is following composition, in the 1st mode, porous member be adjacent to gas and inhale The cross facet part that the face of annex intersects is engaged in cladding bag.
It should be noted that " engagement " refers in the present invention, as described in the embodiment, cladding is included certainly Bag inner surface passes through thermal welding or the situation using engagements such as cements with porous member surface, also including by atmospheric pressure or outer Power is pressed against porous member surface, the state being close to it.
Thus, in order that being connected with gas absorption device in vacuum insulation part, as long as in the intersection face of porous member Office will coat bag perforation, will be adsorbed by gas absorption part by porous member from the gas outside cladding bag.Thus, The velocity of gas sorption of gas absorption part can arbitrarily be set control by the aperture and porosity of porous member.As it As a result, while the effect of the 1st above-mentioned mode is obtained, the deviation amplitude of velocity of gas sorption is reduced, makes absorption property steady It is fixed, and velocity of gas sorption can be slowed down, gas sorption ability is maintained within the longer time.
That is, as so existing gas absorption device, by glass encapsulation materials crush and make its connect composition in, due to The connection area that the breach for being crushed and being formed is produced cannot determine, so the fast and slow situation mixing of velocity of gas sorption is deposited Easily become big in, its deviation amplitude.Allow to the deviation amplitude to be in the range of design size, in order to further reduce partially Spread degree stablizes gas absorption performance also can be with big difficulty.In addition, the connection area that will be brought by breach is limited in Below certain value, by velocity of gas sorption low speed, make gas sorption ability maintain the longer time when also with big difficulty.
However, according to which, both having played the effect described in the 1st mode, gas absorption part is made again via porous member Adsorbed gas.Thus, by controlling aperture and the porosity of porous member, velocity of gas sorption can be made to become deviation amplitude small And it is approximately fixed.And, can take into account what the further stabilisation and gas sorption ability of gas absorption performance were held time Long-timeization.
3rd mode of the invention is following composition, and in the 2nd mode, the cross facet part of porous member is thermally fused to Coat the inner surface of bag.
Thus, the cross facet part of porous member with cladding bag inner surface, its entire surface by physically integration, because This makes after in the gas that the hole that the cross facet chadless of porous member is obtained flows into reliably by porous member, by gas Body adsorption piece is adsorbed.Therefore, it is possible to make the effect of the 2nd mode more reliable.

Thus, the inner surface of cladding bag is melted with porous member by the mutual phase of resin, its entire surface ground very close to each other quilt Reliably engage.And, it is also possible to when bag encapsulation will be coated, while the welding for coating bag is encapsulated, carry out in cladding bag Surface and the engagement on porous member surface, can both improve stability, again improve productivity ratio.
5th mode is following composition, and in the arbitrary mode in from the 1st mode to the 3rd mode, porous member passes through will Toner is sintered and formed.
Thus, porous member will not be ftractureed due to external force when perforating, and be prevented from via breach part, and gas is let out Dew is adsorbed in gas absorption part.Therefore, the necessarily adsorbed gas via the hole of porous member of gas absorption part, can promote gas The stabilisation of absorption property.
During 6th mode is the arbitrary mode in the 1st mode~the 5th mode, gas is led to although porous member has Cross but gas absorption part the intransitable cell structure of powder particle.
Thus, when will coat decompression encapsulation in bag, can reliably prevent from coating the gas absorption part in bag by porous Part and be discharged from inside cladding bag, can make the effect of the 1st mode prevents when encapsulation is depressurized gas absorption part from bag The effect for covering bag exhaust is more reliable.
During 7th mode is the arbitrary mode in the 1st mode~the 6th mode, gas absorption part is Copper Ion Exchange ZSM-5 type zeolites.
Thereby, it is possible to play, Copper Ion Exchange ZSM-5 bigger than the gas absorption capacity of existing gas absorption device The characteristics of type zeolite, good gas absorption performance is played in a long time.
8th mode is the laminated film that cladding bag is formed in the 4th mode also with the protection on the surface for coating gas barrier layer Layer.
Thus, due to protecting the metal foil as gas barrier layer using protective layer, it is prevented from coating the film of bag by not Metal foil is unexpected damaged during necessary external force, the deterioration of gas absorption part when can reliably prevent from preserving.
9th mode is that in the 8th mode, protective layer is by PET (polyethylene terephthalate) or equal with PET The resin of following water absorption rate is constituted.
Thereby, it is possible to prevent when gas absorption device is preserved, protective layer absorbs the moisture in air, is being applied to vacuum During insulation etc., moisture is released in the overcoating part of vacuum insulation part etc., inhales the vacuum reduction in overcoating part, or gas The gas sorption ability of annex is consumed in the moisture absorption.Therefore, it is possible to maintain gas absorption performance for more time, keep Apply the excellent heat insulating performance of the vacuum insulation part of gas absorption device etc..
During 10th mode is the arbitrary mode in the 1st mode~the 9th mode, gas absorption part and porous member it Between be provided with water adsorption part.
Thus, the gas from porous member, can be by gas by being adsorbed by gas absorption part after water adsorption part Contained humidity Adsorption.Therefore, it is possible to prevent gas absorption part due to being wasted caused by water adsorption, can be in the longer time It is interior, it is ensured that good gas absorption performance, improve reliability.
11st mode is vacuum insulation part, including：The gas absorber of the arbitrary mode in the 1st mode~the 10th mode Part, core and overcoating part, the vacuum insulation part are inserted in overcoating part by by gas absorption device and core, and carry out decompression envelope Fill and constitute.
Thereby, it is possible to realize following vacuum insulation part, i.e. even the thin vacuum insulation part of several millimeters thickness or so And make the vacuum insulation part of its bending etc., it is also possible to gas absorption effect, in a long time, keep good thermal insulation Energy.
12nd mode is that in the 11st mode, gas absorption device is to enter eleven punch 11 by the part in porous member, is made With the composition connected in gas absorption device in overcoating part.
Thus, because the gas in vacuum insulation part is adsorbed by porous member and by gas absorption part, it is possible to Aperture and porosity according to porous member arbitrarily set the velocity of gas sorption of control gas absorption part.Therefore, it is possible to reality Now following vacuum insulation part, i.e. both obtained the effect of the 1st mode, makes gas absorption performance zero deflection and stabilization, and subtract again Slow velocity of gas sorption maintains gas sorption ability, within the longer time, plays good heat-insulating property.
13rd mode is friendship with porous member of the gas absorption device in cladding bag in the 11st mode or the 12nd mode The opposite segments of fork face part possess the Kaifeng part of thrust.
Thus, when gas absorption device being carried out into Vacuum Package in the overcoating part of vacuum insulation part, by Kaifeng part Thrust will coat bag perforation, and the gas absorption part of inside can be made to be connected with the vacuum area in overcoating part.Thereby, it is possible to anti- Only the extraneous air when bag perforation is coated in gas absorption part absorption air is deteriorated, can be by the thermal insulation of vacuum insulation part Performance maintenance bond within the longer time is good performance.
The technical inspiration of each following mode can be independently of each mode of above-mentioned the 1st mode~the 13rd mode Technical inspiration enlightenment.
14th mode of the invention is gas absorption device Kaifeng part.The Kaifeng part of the gas absorption device exists One side of the spring being made up of wire rod is provided with the handle part for clamping gas absorption device.And, the front end of another side is by structure Into the perforated portion of the perforate on gas absorption device.
By such composition, Kaifeng part using the leading section of spring wire as perforated portion, by gas absorption device Adsorption piece accommodating container is perforated.Thus, the aperture in the hole is the gauge or diameter of wire of spring wire, even if due to the applying mode of external force And have the deviation of penetration depth, but can also turn into certain size.Therefore, it is possible to by the gas around adsorption piece accommodating container with Do not have adsorption rate devious stably to adsorb.Being additionally, since only can just form spring wire bending, compared with flat spring Fee of material can be made cheaply a lot, and work manhours can be made also to only have the bending machining of spring wire, therefore, it is possible to significantly drop Low cost, can inexpensively provide.
15th mode of the invention is that in the 14th mode, the spring being made up of wire rod turns into coiled type.Make one end The close coil rolling density in another side of coil rolling density of side, the handle part that composition clamps gas absorption device.Separately Outward, to handle part lateral bend, it is formed in gas absorption device perforate by by the fore-end of the thin another side of loop density Perforated portion.
Thus, in handle part, because coil rolling density is close, it is possible to reliably holding gas absorption device.Separately Outward, the gas absorption device perforation of the part of handle part is will remain in because perforated portion can enter to handle part side pressure, so Reliable perforation can be realized.
In addition, the 16th mode of the invention is in the 14th mode or the 15th mode, handle part is configured to wind coil More than at least one circle between line it is in close contact.
Thus, in handle part, spring wire turns into close contact reeling condition, being capable of strength by close contact winding part Ground holds gas absorption device.Perforation error caused by therefore, it can suppress the position skew of Kaifeng part and coming off, can Realize more reliable perforation.
17th mode of the invention is that in the 14th mode~the 16th mode, perforated portion passes through will be from coiled type part to line The fore-end of the wire rod of circle central part bending is constituted to handle part lateral bend.
Thus, perforated portion is the line of the handle part that the hub of a spool of coiled type part will be held gas absorption device Circle immediate vicinity perforation.Therefore, it is possible to prevent the adjacent edges without gas absorption part by the periphery of gas absorption device from wearing The such perforation error in hole, can reliably perforate.
During 18th mode is the arbitrary mode in the 14th mode~the 17th mode, the section of wire rod is circle or oval Shape, its outer peripheral face is made arc-shaped.
Thus, in the state of for vacuum insulation part, though the overcoating part of vacuum insulation part due to atmospheric pressure by very In the case of being pressed against by force at the spring wire of Kaifeng part, because the outer peripheral face of spring wire is in arc-shaped, so will not When at overcoating part as using flat spring, produce due to stress concentration caused by the angle of flat spring.It is outer thereby, it is possible to prevent The broken bag of part is covered, the vacuum of vacuum insulation part is reliably kept, it is possible to increase reliability.
19th mode is gas absorption device.The gas absorption device possesses reduced pressure sealing and has the flat of gas absorption part Adsorption piece accommodating container and the 14th mode~the 18th mode among Kaifeng part described in arbitrary mode.And, seal opening portion Part is clamped adsorption piece accommodating container by handle part, is assemblied on adsorption piece accommodating container.And, it is configured to by perforated portion Adsorption piece accommodating container side is pressed into, adsorption piece accommodating container can be perforated.
Thus, the gas absorption device can implement the small perforation of deviation for adsorption piece accommodating container, will can adsorb Gas around part accommodating container is stably adsorbed.Further, due to break a seal part cost reduction, correspondingly can be honest and clean Valency ground provides gas absorption device.
In addition, the 20th mode is following composition, in the 19th mode, adsorption piece accommodating container is by the lamination with gas barrier property The bag of film is constituted, and the opening portion of bag is enclosed, and gas absorption part is depressurized sealing, and the opening portion of bag is set to only be laminated The thinner wall section of film layer.
Thus, in the part of Kaifeng, by its handle part from the part of the thinner wall section of only laminate film layer, it is readily inserted into gas The adsorption piece accommodating container of absorbing elements is simultaneously held, it is possible to increase operating efficiency.
21st mode is following composition, and in the 19th mode or the 20th mode, being inserted with adsorption piece accommodating container makes gas Body passes through but does not make porous member that the powder particle of gas absorption part passes through and be depressurized sealing, and gas absorption part with it is porous Part is abutted with plane state.
Thus, the gas absorption device is manufactured after using general vacuum extractor decompression by sealing welding, this When, i.e. when the bag as adsorption piece accommodating container for being inserted with gas absorption part is depressurized sealing, by lateral from porous member Gas absorption part side to carrying out suction decompression in bag, due to the presence of porous member, be prevented from gas absorption part in bag from Exhaust is sucked in bag.Therefore, it is possible to not use special device, the pumping exhaust that the there is no need ground of gas absorption part is prevented Manufactured, and, decompression encapsulation can carried out with not slowing down vacuum pumping rate, productivity ratio is improved, can inexpensively carry For.
Further, since gas absorption part and porous member in flexible adsorption piece accommodating container with plane state quilt Adjacent configuration, so compared with the situation of configuration that gas absorption part and porous member overlap, can make thinner, makes bending Become easy Deng deformation.Thus, it is also possible to be applied to the thin vacuum insulation part of several millimeters or so and bend to arc-shaped use Vacuum insulation part.And, become big by by the plane width of adsorption piece accommodating container, while thickness of thin being kept, make The quantitative change of gas absorption part is more, can maintain gas sorption ability in a long time.
22nd mode is following composition, and in the 21st mode, Kaifeng part is fitted to be many of adsorption piece accommodating container Hole portion part chadless.
Thus, gas absorption device is via the gas around porous member absorption.Therefore, it is possible to the hole according to porous member Footpath arbitrarily sets the velocity of gas sorption of control gas absorption part.Following gas absorption device can be realized, it can either be obtained Productivity ratio to the 21st above-mentioned mode improves effect etc., makes gas absorption performance with further having deviation unstable again, and will Velocity of gas sorption is slack-off to maintain gas sorption ability, and good gas absorption performance is played within the longer time.
23rd mode is following composition, in the 22nd mode, moisture is provided between gas absorption part and porous member Adsorption piece.
Thus, even if gas absorption device contains moisture from the gas of ambient absorption, it is also possible to by the moisture moisture Adsorption piece Adsorption.Therefore, it is possible to prevent gas absorption part due to being wasted caused by water adsorption, can be within the longer time Ensure good gas absorption performance, be made reliability gas absorption device high.
24th mode is following composition, in the arbitrary mode of the 21st mode~the 23rd mode, constitutes adsorption piece storage The bag of container is made up of the laminated film of the multilayer comprising the gas barrier layer containing metal foil, the membrane element and porous member of its innermost layer To be capable of the resin material of mutual thermal welding, and it is heating-fusion bonded.

As shown in figure 1, the vacuum insulation part 1 of present embodiment by the inside of overcoating part 2 by gas absorption device 4 with After core 3 is set together, decompression encapsulation is carried out, make to be connected with the inside of overcoating part 2 and constituted inside gas absorption device 4.Need Illustrate, although not shown, but can be provided with moisture suction together with core 3 and gas absorbing elements 4 inside overcoating part 2 Attached dose of composition.Moisture (vapor) in moisture adsorbent absorption remaining or intrusion vacuum insulation part.It should be noted that As moisture adsorbent, although be not particularly limited, but the chemical adsorptivity materials such as calcium oxide or magnesia, boiling can be used Physical adsorbability material as stone or these mixture.
Gas absorption device 4 as shown in Fig. 2 by the flexible cladding bag 5 with gas barrier property, by porous member 7 Inserted together with gas absorption part 6, constituted through decompression encapsulation.And, gas absorption part 6 is with porous member 7 with plane The mode of state adjoining configuration is constituted.
It should be noted that gas absorption part 6 is configured on the length direction of gas absorption device 4 with porous member 7 Different parts.
Further, gas absorption device 4 as shown in Figures 2 and 3, is coating the cross facet part with porous member of bag 5 7a relative part possesses the Kaifeng part 9 of thrust 8 (reference picture 6).
Here, the cladding bag 5 of gas absorption device 4 for example at least has as shown in Figure 5 by by gas barrier property film high Outermost protective layer 10a, in middle gas barrier layer 10b, at least three layers of bonding layer 10c of innermost layer of laminated film (films 10) thermal welding pouch and constitute.
In present embodiment, as cladding bag 5, as shown in figure 3, two peripheries of laminated film are passed through into thermal welding (light ash Color part) form bag-shaped.However, cladding bag 5 of the invention is not limited to this composition, for example, a laminated film can also be made bag The arbitrary form such as shape.
On the other hand, among film 10, the bonding layer 10c being made up of the membrane element of innermost layer is to make the peripheral part between film 10 The layer being securely engaged by thermal welding, uses the resin for being capable of thermal welding.Use such as straight-chain low density polyethylene (LDPE) (LLDPE), low density polyethylene (LDPE) (LDPE), high density polyethylene (HDPE) (HDPE), metallocene PE, ethylene-acrylic acid copolymer Or ethylene-methacrylic acid copolymer (EMAA) (EAA).Alternatively, it is also possible to use tensionless winkler foundation polypropylene (CPP), biaxial stretch-formed Polypropylene (OPP), polyethylene terephthalate (PET), vinyl-vinyl acetate copolymer (EVA) or ionomer etc. Resin film.
In addition, the gas barrier layer 10b in the intermediate layer as film 10 uses air-locked aluminium foil (Al paper tinsels), Copper Foil (Cu paper tinsels) or not The metal foils such as rust steel foil.In addition, according to circumstances can also be by the low ethylene-vinyl alcohol copolymer resin film of gas-premeable On the resin film of (EVOH films) or polyethylene terephthalate film (PET film) etc., the film that the metal such as evaporating Al or Cu is obtained The film structure that the metal oxide such as (metal deposition film) or steam coating silicon dioxide, aluminum oxide or diamond-like-carbon (DLC) etc. are obtained Into.
Further, the outermost protective layer 10a as film 10 is the layer for protecting gas barrier layer 10b, it is possible to use nylon membrane, Polyethylene terephthalate film (PET film), polyethylene film (PE films) or polypropylene screen (PP films) etc..Among these, preferably The low film of water absorption rate, such as PET film, PE films or PP films etc., as long as the resin with the equal following water absorption rates of PET, then can Any resin is enough used, above-mentioned example is not particularly limited in.
It should be noted that, although it is not shown, as the film 10 for constituting cladding bag 5, if in gas barrier layer 10b and bonding layer Nylon membrane is used between 10c, then due to the intensity of the entirety of film 10 can be improved, so being effective.That is, as gas absorption part 6 using in the case of such as Copper Ion Exchange ZSM-5 types zeolites, if having the big particle of particle diameter in the particle of zeolite, film 10 part relative with the particle can be applied in big tensile force, sometimes on the aluminium foil for constituting gas barrier layer 10b, with big Particle is that starting point occurs crackle and pinprick.However, by using nylon membrane in film 10, then can suppress with bulky grain as starting point Crackle and pinprick generation, more effectively.
In addition, in cladding bag 5, the porous member 7 enclosed together with gas absorption part 6 is toner is sintered and is had Have the structure in three-dimensional netted hole, although with do not make gas absorption part 6 powder particle pass through pass the gas through it is porous Structure.
By vacuumizing in the manufacturing process of gas absorption device, the inner surface of bag 5 is coated because atmospheric pressure is connect Together in porous member 7.In present embodiment, the resin for constituting porous member 7 is by the engagement with the innermost layer as cladding bag 5 Layer 10c has the resins such as the thermoplastic resin of compatibility, straight-chain low density polyethylene (LDPE) (LLDPE) as escribed above to constitute, its Cross facet part 7a with constitute cladding bag 5 innermost layer bonding layer 10c by thermal welding by physically integrated.
On the other hand, the chemical absorbing substances such as calcium oxide or magnesia, zeolite can be applicable so as gas absorption part 6 Physical absorption material or these mixture or BaLi4 etc. gas-adsorbing alloy.In the present embodiment, gas is used Body adsorption capacity and the extra high Copper Ion Exchange ZSM-5 type zeolites of adsorption capacity.It is high as other gas sorption abilities Sorbing material have in the ZSM-5 types zeolite containing barium (Ba) or strontium (Sr) and ZSM-5 type zeolites containing M-O-M kinds (M：Ba or Sr, O：Oxygen) sorbing material etc., it is possible to use be applied in combination for these by these.
In addition, Kaifeng part 9 is made up of the synthetic resin or metal of the intensity with appropriateness and elasticity.In the feelings for resin Under condition, as long as gas occurs less, is able to ensure that the hardness of thrust 8, polypropylene, polybutylene terephthalate (PBT), Polystyrene, polyamide, makrolon, polyoxyethylene methylene, AS resins and ABS resin etc. turn into candidate.
As shown in Figure 3 and Figure 6, thrust 8 is assembled into relative with the cross facet part 7a of porous member 7 Kaifeng part 9.Gas Body absorbing elements 4 are depressurized when in the overcoating part 2 for be encapsulated in vacuum insulation part 1, and gas absorber is pressed into due to atmospheric pressure The side of porous member 7 of part 4.And, cladding bag 5 is perforated, in internal gas absorption part 6 and the overcoating part 2 of vacuum insulation part 1 Portion connects.
Next for gas absorption device 4 as constructed as above and the vacuum insulation part 1 for having used it, illustrate that it is acted And effect.
In the cladding bag 5 with gas barrier property, decompression is packaged with gas absorption part 6 to gas absorption device 4.Coating bag 5 is Flexible, in the inside of cladding bag 5, gas absorption part 6 is abutted with plane state with porous member 7 and configured.Thereby, it is possible to logical Crossing after being depressurized using general vacuum extractor is carried out thermal welding and manufactures.Its part being heating-fusion bonded be in figure 3 with The part that Dark grey is represented.
Here, when decompression encapsulation in the cladding of gas absorption part 6 bag 5 will be inserted with, by from the lateral gas of porous member 7 The side of body adsorption piece 6, due to the presence of porous member 7, is prevented from coating the gas in bag 5 and inhales to suction decompression in cladding bag 5 Annex 6 is vented from cladding bag 5.That is, suction row is carried out from the thermal welding packed part side represented with Dark grey in figure 3 Gas, is prevented from coating the gas absorption part 6 in bag 5 and is vented from cladding bag 5.
Therefore, the gas absorption device 4 of present embodiment is not used in such special dress described in background technology column Putting can just manufacture, and can not become vacuum pumping rate slowly to carry out decompression encapsulation, can improve productivity ratio, and inexpensively Ground is provided.
In addition, gas absorption part 6 is abutted in flexible cladding bag 5 with porous member 7 with plane state Configuration.Because cladding bag 5 is constituted by with flexible film, so the configuration that overlapped with gas absorption part 6 and porous member 7 Situation is compared, and can realize making thinner, and deforms bending etc. easy.Thus, it is also possible to be applied to the thin of several millimeters or so Vacuum insulation part and bend to vacuum insulation part that arc-shaped is used etc..
It should be noted that gas absorption part 6 and porous member 7 are in the configuration of the length direction of gas absorption device 4, It is configured in different parts.
Thus, for example, in the case of gas absorption part 6 using powdery, no matter the presence or absence of flexibility of porous member 7, all The flexibility of gas absorber part 4 can be obtained.
In addition, make porous member 7 be gas absorption device 4 length direction total length less than 1/2 in the case of, due to Velocity of gas sorption can be made slack-off, gas sorption ability can be made to be maintained within the longer time, therefore preferably.In addition, making many Hole portion part 7 turns into the case of less than the 1/4 of the total length of the length direction of gas absorption device 4, even if the flexibility of porous member 7 It is overall as gas absorption device 4, it is also possible to flexibility, therefore preferably in the case of difference.
Further, become big by making the plane width of cladding bag 5, gas absorption can be made while thickness of thin is kept The quantitative change of part 6 is more, can in a long time maintain gas sorption ability.Here, plane width refers to, for example, cladding bag 5 is overlooked When for quadrangle or it is polygonal in the case of, at least size on the size on its one side or relative side, in the case of oval It is the size of long leg point, in addition, being the size of its diameter dimension etc. in the case of for circle.
In addition, in the gas absorption device 4 of present embodiment, porous member 7 is handed over the face for being adjacent to gas absorption part 6 The cross facet part 7a of fork is engaged with the cladding inner surface of bag 5.Thus, make in vacuum insulation part 1 and in gas absorption device 4 During connection, eleven punch 11 is entered to cladding bag 5 by the cross facet part 7a parts in porous member 7, from the gas outside cladding bag 5 Body by gas absorption part 6 in porous member 7 by being adsorbed.Thus, the velocity of gas sorption of gas absorption part 6 can be by porous The aperture of part 7 and porosity, arbitrarily setting control.
Therefore, it is possible to reduce the deviation amplitude of gas absorption performance, make absorption property stabilization, and velocity of gas sorption is become Slowly, gas sorption ability can be maintained within the longer time.
That is, as existing gas absorption device, glass encapsulation materials is crushed and the composition of connection is formed, by Crushing the connection area that the breach to be formed produces cannot determine, have that velocity of gas sorption is fast and slow situation is mixed, its Deviation amplitude easily becomes big.Although making the deviation amplitude be in the range of design size, in order to further reduce deviation amplitude Stablizing gas absorption performance also can be with big difficulty.In addition, the connection area that will be brought by breach is limited in certain value Hereinafter, by velocity of gas sorption low speed, when gas sorption ability is maintained the longer time, also with greatest difficulty.
However, the gas absorption device 4 according to present embodiment, gas absorption part 6 via the adsorbed gas of porous member 7, Therefore by controlling aperture and the porosity of porous member 7, velocity of gas sorption can be set to small substantially solid of deviation amplitude Fixed value.Therefore, it is possible to the further stabilisation and gas sorption ability of taking into account gas absorption performance hold time it is long when Between change.
In addition, in the gas absorption device 4 of present embodiment, due to the cladding inner surface of bag 5 and intersecting for porous member 7 Face part 7a is engaged, so the gas entered from the hole opened in cross facet part 7a by perforation passes through in porous member 7 Adsorbed by gas absorption part 6 afterwards.Therefore, as described above, the gas adsorbability brought by porous member 7 can be realized accurately Stabilisation and the adsorption rate control of energy.
In present embodiment, the membrane element and porous member 7 of the bonding layer 10c of the innermost layer as cladding bag 5 are by can The resin material of thermal welding is constituted, and is heating-fusion bonded.Therefore, the cross facet part 7a of porous member 7 melts as indicated with broken lines in fig. 4 Melt and with cladding bag 5 inner surface it is physically integrated.Therefore, it is possible to prevent from coating the inner surface and porous member 7 of bag 5 The minim gap of residual fraction between the 7a of cross facet part, prevents gas from being adsorbed by gas absorption part 6 from the part.That is, as long as It is present embodiment, due to perforation, from after the gas that the hole that cross facet part 7a is opened enters must be by porous member 7 Adsorbed by gas absorption part 6.Thereby, it is possible to accurately realize the above-mentioned gas absorption performance brought by porous member 7 Stabilize and adsorption rate control.
Further, the inner surface of above-mentioned cladding bag 5 can be with encapsulation with the engagement of the cross facet part 7a of porous member 7 The thermal welding carried out during cladding bag 5 is while carry out.Be additionally, since and used thermoplastic resin material, thus by resin it Between mutually melt, reliably by its entire surface engage, it is possible to increase while productivity ratio, improve stability and adsorption rate control The precision of system.
Further, since porous member 7 by by toner sinter and is formed, so porous member 7 will not because perforate when External force and ftracture, be prevented from via cracking, gas leakage is adsorbed to gas absorption part 6.Therefore, gas absorption part 6 Necessarily the adsorbed gas via the hole of porous member 7, can promote the stabilisation of gas absorption performance.
In addition, porous member 7 has three-dimensional netted hole, although not passing through gas absorption part 6 with passing the gas through The cell structure of powder particle.Thus, during decompression encapsulation, can reliably will prevent from coating the gas in bag 5 in cladding bag 5 Adsorption piece 6 is vented by porous member 7 from cladding bag 5, can be more reliably prevented from the gas absorption part 6 when encapsulation is depressurized From the exhaust of cladding bag 5.
On the other hand, gas absorption device 4 when stored, will not cause perforation because of Kaifeng part 9, be protected by coating bag 5 It is decompression air-tight state to hold.Therefore, gas absorption part 6 will not be with outside air contact, the adsorption capacity quilt of gas absorption part 6 Maintain.
The film 10 for constituting cladding bag 5 possesses the gas barrier layer 10b comprising the metal foil for being not through gas.Thereby, it is possible to strength Ground suppress infiltration of external air enter to coat in bag 5 and gas absorption part 6 through when deteriorate.Therefore, it is possible to by gas absorption part 6 Adsorption capacity maintains state high, can in a long time play good gas sorption ability.
Further, since the gas barrier property of cladding bag 5 is high, even if using Copper Ion Exchange ZSM-5 types as gas absorption part 6 The sorbing material high of gas sorption ability as zeolite, it is also possible to securely maintain its adsorption capacity, inhales with using with high The gas absorption part of attached ability is engaged, and can in a long time play better gas sorption ability.
Further, the composition for forming the film 10 of cladding bag 5 is the protective layer 10a on the surface with cladding gas barrier layer 10b.Cause This, the metal foil for turning into gas barrier layer 10b is protected using protective layer 10a, is subject to unnecessary outer in the film 10 of cladding bag 5 During power, the unexpected breakage of metal foil, the deterioration of the gas absorption part 6 when can reliably prevent from preserving are prevented from.
In addition, the protective layer 10a of cladding bag 5 is by PET (polyethylene terephthalate) or with PET equal following The resin of water absorption rate is constituted.Therefore, it is possible to prevent in the preservation of gas absorption device, due in protective layer 10a absorption air Moisture, so when suitable for vacuum insulation part 1, moisture is released into the overcoating part 2 of vacuum insulation part 1, make overcoating part 2 Interior vacuum reduction or the gas sorption ability of gas absorption part 6 are consumed due to the absorption of moisture.Therefore, it is possible to Gas absorption performance is maintained in the longer time, can make to be applicable the heat-insulating property of the vacuum insulation part 1 of gas absorption device Keep good.
It should be noted that protective layer 10a be PET or the resin of the water absorption rate with the equal following degree of PET then more It is preferred that, but it is not particularly limited to these examples.
Gas absorption device 4 described above, is inserted in inside bag-shaped overcoating part 2 together with core 3, is being vented to After vacuum, encapsulated by by the bag opening portion thermal welding of overcoating part 2, and used as the adsorption piece of vacuum insulation part 1.
Fig. 7 is the schematic diagram for illustrating the manufacture method of above-mentioned vacuum insulation part 1.
Vacuum insulation part 1 is placed into the decompression chamber 12 of vacuum packaging machine 11, using vavuum pump 13 to decompression chamber 12 Inside carry out vacuum exhaust.Thus, the gas being cladded with part 2 is vacuum exhausted and is depressurized, using heat sealing machine 14 by overcoating part 2 Opening portion thermal welding, is packaged to manufacture vacuum insulation part 1.
Now, in gas absorption device 4, Kaifeng part 9 is pressed into by atmospheric pressure, or the part that will be broken a seal after Vacuum Package 9 are mechanically pressed into, and thrust 8 is pricked on film 10, and film 10 is perforated.
Thus, the inside of gas absorption device 4 connects with the inside of the overcoating part 2 of vacuum insulation part 1, makes by gas absorption The gas of remaining etc. carries out absorption and is possibly realized in 6 pairs of overcoating parts 2 of part.
In addition, film perforation be to carrying out vacuum exhaust in the overcoating part 2 of vacuum insulation part 1 when, or vacuum Carried out after encapsulation.When carrying out vacuum exhaust thereby, it is possible to prevent from being put into after as film is perforated in an atmosphere in overcoating part, During gas absorption part 6 exposes air in an atmosphere when film is perforated, adsorb air and deteriorate.Therefore, it is possible to gas is inhaled The maintenance bond within the longer time of the gas absorption performance of annex 6 is good performance.
In addition, the Kaifeng part 9 that film 10 is perforated occurs few resin by metal or gas being formed.Thereby, it is possible to prevent The release gas in the overcoating part 2 of vacuum insulation part 1, makes the vacuum reduction in overcoating part 2, or same with the situation of film 10 Ground, makes the gas sorption ability of gas absorption part 6 consume in the absorption of the gas.Therefore, because can be interior in the longer time, Good gas absorption performance is maintained, the excellent heat insulating performance of vacuum insulation part 1 is kept, thus it is more effective.
In the vacuum insulation part 1 for so being formed, because gas absorption device 4 is thin and with flexibility, even so number milli The vacuum insulation part of the thick degree of rice, or be bent the vacuum insulation part for waiting, it is also possible to by by gas absorption device 4 and core 3 Enclose together and use, make it have gas absorption effect, the vacuum with good heat-insulating property in a long time can be realized Insulation.
In addition, in gas absorption device 4, the part of porous member 7 is perforated, it is cladded with part 2 and in gas absorption device 4 Connection.Therefore, as described above, the gas in vacuum insulation part 1 is adsorbed, gas by porous member 7 by gas absorption part 6 The velocity of gas sorption of adsorption piece 6 can by the aperture and porosity of porous member 7 at least any one come arbitrarily Setting control.Therefore, it is possible to stabilizing gas absorption property, and can realize playing good heat-insulating property within the longer time Vacuum insulation part.
In addition, gas absorption device 4 is configured to the counterpart of the cross facet part 7a in its porous member 7 for coating bag 5 Divide and possess the Kaifeng part 9 with thrust 8.Therefore, gas absorption device 4 is being vacuum packaged in the outer of vacuum insulation part 1 Cover when in part 2, perforated bag 5 is coated by the thrust 8 of Kaifeng part 9, the gas absorption part 6 and overcoating part 2 of inside can be made Interior vacuum area connection.During therefore, it is possible to preventing cladding bag from perforating, the extraneous air hair in the absorption air of gas absorption part 6 Raw deterioration, the thermal insulation of vacuum insulation part 1 can be obtained well in interior maintenance bond for more time.
(the 2nd implementation method)
Next, being illustrated to the 2nd implementation method of the invention.
Fig. 8 is to schematically show the composition of the gas absorption device in the 2nd implementation method of the invention from the side Figure.
The composition of the gas absorption device 4 in present embodiment is to be provided between gas absorption part 6 and porous member 7 Water adsorption part 15.
According to this composition, the gas from porous member 7 is adsorbed after passing through water adsorption part 15 by gas absorption part 6, energy Enough by contained humidity Adsorption in gas.Thus it is possible to prevent gas absorption part 6 to be wasted due to water adsorption, can Within the longer time, it is ensured that good gas absorption performance, reliability is improved.
Further, since can suppress gas absorption part 6 due to the waste of adsorption capacity caused by water adsorption, so not Be considered as the Copper Ion Exchange ZSM-5 type zeolites that gas absorption part 6 is used due to caused by water adsorption consume, energy The dosage of Copper Ion Exchange ZSM-5 type zeolites is enough reduced, the miniaturization of gas absorption device 4 can be sought.
Further, the bonding layer 10c of the film 10 of cladding bag 5 is constituted, compared with the melt temperature of glass etc., can be low very Many temperature meltings, therefore, it is possible to hot melt jointing temp is greatly reduced.Therefore, even if setting water adsorption simultaneously in cladding bag 5 Part 15, it is also possible to prevent from water adsorption part 15 produce gas cause the performance degradation of gas absorption part 6, can realize together It is provided with the high performance gas absorption device 4 of water adsorption part 15.
For example, the material as bonding layer, for example, PE its own in 100 DEG C~140 DEG C meltings, PP is molten at 130 DEG C or so Melt, EMAA or ethene system ionomer are in 100 DEG C or so meltings.In the case that these are made into laminated film, although because of its lamination knot Structure and thickness are different, but can carry out welding at about 160 DEG C~190 DEG C or so.Even if set in cladding bag 5 simultaneously Water adsorption part 15, it is also possible to prevent from making the performance degradation of gas absorption part 6, Neng Goushi by the disengaging gas of water adsorption part 15 The high performance gas absorption device 4 of water adsorption part 15 is now provided with together.
It should be noted that calcium oxide (CaO), silica gel, zeolite or molecular sieve can be used as water adsorption part 15 Etc. various materials.
It is as others composition and action effect and the 1st implementation method likewise, being marked for identical element part Same sequence number simultaneously eliminates explanation.
(the 3rd implementation method)
Next, being illustrated for the 3rd implementation method.
Fig. 9 is to schematically show the composition of the gas absorption device in the 3rd implementation method of the invention from the side Figure.
Gas absorption device 4 in present embodiment is coated in bag 5 by one, and multigroup gas absorption part is enclosed in decompression 6 and porous member 7 combination and constitute.
According to this composition, by changing aperture and the porosity of each porous member 7 in advance, gas absorption speed can be changed Degree, can take into account the quick-acting and maintenance of gas absorption, more effectively.
For example, the respective aperture of multiple porous members 7 and porosity are predisposed to, and some are larger, other are smaller, Then in aperture and the big porous member 7 of porosity, because velocity of gas sorption is fast, so the gas in vacuum insulation part is in short-term Between be adsorbed, in the manufacture of vacuum insulation part, speed is played on the Adsorption of the gas of remaining will fail decompression exhaust Effect property.In addition, in other apertures and the small porous member 7 of porosity, velocity of gas sorption is slack-off.Here, in overcoating part, The adsorption rate of the moisture adsorbent set in addition with gas absorption device is slower than by making the adsorption rate of gas absorption part 6, The major part of contained humidity in the long-term gas invaded through overcoating part can be made by moisture adsorbent Adsorption.Accordingly, it is capable to Enough prevent gas absorption part 6 due to being wasted caused by water adsorption, persistently can adsorb in vacuum insulation part in a long time Gas.Therefore, it is adaptable to be suitable during the large-scale vacuum insulation part that building materials or LNG ship etc. are middle to be used.
Other action effects are identical with what is illustrated in the 1st implementation method and the 2nd implementation method, therefore omit the description.
More than, said for gas absorption device involved in the present invention and using its vacuum insulation part It is bright, but the invention is not restricted to these.
For example, in embodiments, as the part that porous member 7 is constituted exemplified with toner is sintered, but only If with the part of function for passing through the powder particle of gas absorption part 6 but to pass the gas through, or for example without Spin the material of cloth or mineral wool etc..In addition, hole shape may not be three-dimensional netted hole, or than gas absorption part 6 The through hole group of the small straight line of powder particle particle diameter.It should be noted that in the case of using non-woven fabrics or mineral wool, due to than Porous member it is flexible excellent, by vacuum insulation part bend etc. deformation be easier.
In addition, the form of cladding bag 5 is also not limited to three flour bags illustrated in implementation method, or dual bag, double The bag of any form of flour bag or rivel bag etc..
Further, the inner surface of cladding bag 5 can not be thermal welding with the engagement of the cross facet part 7a of porous member 7, Can also be carried out using cement.
That is, all aspects in implementation method of disclosure are all to illustrate, and are not considered as restricted content, this The scope of invention is indicated not by the above-noted description, but is represented with claims, it is intended that comprising impartial with claims Being had altered in meaning and scope.
(the 4th implementation method)

It should be noted that as the spring wire of Kaifeng part 108, it is possible to use stainless steel and other metal materials, but only If gas occurs few material in vacuum atmosphere, then can be any material, or can for example make it have bullet The resin material of spring.
On the other hand, the adsorption piece accommodating container 105 of gas absorption device 104 is for example such as schemed by by gas barrier property film high At least having by by outermost protective layer 112a, by by middle gas barrier layer 112b, by by innermost layer shown in 12 At least three layers of bonding layer 112c of the sealing welding of laminated film 112 constituted for bag-shaped.
In present embodiment, as shown in figure 14, adsorption piece accommodating container 105 is configured to, by two peripheries of laminated film 112 Sealing welding (light gray part) pouch, its opening portion (dark gray section) is set as only together with the periphery of laminated film 112 There is the thinner wall section 105a of laminate film layer.It can also be that a laminated film 112 for example is made into bag-shaped etc. any form.
In addition, among laminated film 112, the bonding layer 112c being made up of the membrane element of innermost layer is by between laminated film 112 Peripheral part by sealing the layer that welding is securely engaged.As bonding layer 112c, it is possible to use be capable of the resin of thermal welding, example Such as straight-chain low density polyethylene (LDPE) (LLDPE), low density polyethylene (LDPE) (LDPE), high density polyethylene (HDPE) (HDPE), the poly- second of metallocene Alkene, ethylene-acrylic acid copolymer (EAA) or ethylene-methacrylic acid copolymer (EMAA).Additionally as bonding layer 112c, it is also possible to use tensionless winkler foundation polypropylene (CPP), biaxial stretch-formed polypropylene (OPP), polyethylene terephthalate (PET), the resin film of vinyl-vinyl acetate copolymer (EVA) or ionomer etc..
As the gas barrier layer 112b in the intermediate layer as laminated film 112, using the aluminium foil (Al paper tinsels) without gas-premeable, Metal foil such as Copper Foil (Cu paper tinsels) or stainless steel foil etc..According to circumstances, gas barrier layer 112b can also be by the low second of gas-premeable On the resin film of alkene-EVOH film (EVOH films) or polyethylene terephthalate film (PET film) etc., evaporation The film (metal deposition film) that the metal or metal oxide of Al, Cu etc. are obtained, or the metal oxygen such as steam coating silicon dioxide, aluminum oxide The film that compound or diamond-like-carbon (DLC) etc. are obtained is constituted.
It is the layer for protecting gas barrier layer 112b as the outermost protective layer 112a as laminated film 112.Protective layer 112a Nylon membrane, polyethylene terephthalate film (PET film), polyethylene film (PE films) or polypropylene screen (PP films) can be used Deng.Wherein, the preferably low film of water absorption rate, such as PET film, PE films or PP films etc., as long as with the equal following water absorption rates of PET Resin can be just any resin, be not particularly limited to by above-mentioned example.
On the other hand, gas absorption part 106 can be applicable the chemical adsorptivity such as calcium oxide or magnesia material, zeolite so Physical adsorbability material or these mixture or BaLi4 etc. gas-adsorbing alloy.In present embodiment, use Gas absorption capacity and the extra high Copper Ion Exchange ZSM-5 type zeolites of adsorption capacity.As other gas sorption abilities Sorbing material high contains M-O-M kinds in having the ZSM-5 types zeolite containing barium (Ba) or strontium (Sr) or ZSM-5 type zeolites (M：Ba or Sr, O：Oxygen) sorbing material etc., it is possible to use be applied in combination for these by these.
Gas absorption device 104 when stored, will not cause perforation, by adsorption piece accommodating container because of Kaifeng part 108 105 remain decompression air-tight state.Thus, gas absorption part 106 will not with outside air contact, gas absorption part 106 Adsorption capacity is maintained.
Broken a seal for gas absorption device as constructed as above and part and used its gas absorption device 104 and true Empty insulation 101, is next acted to it and effect is illustrated.
First, part 108 is broken a seal due to being formed by using spring wire, with the Kaifeng part phase being made up of flat spring Than its materials can be greatly reduced.And, the handle part 109 and perforated portion 110 of the part 108 that breaks a seal pass through only by spring wire Bending can just be formed, it is not necessary to which the punching press severing as the Kaifeng part of flat spring formula, punching press for several times bend and cut The multiple operation such as processing made and tilt.Therefore, because materials reduction and man-hour cut down, cost can be greatly reduced, can Gas absorption device 104 is inexpensively provided.
In addition, Kaifeng part 108 clamps gas absorption container using its handle part 109, to be assemblied in gas absorption container State use.Because the peripheral edge portion of the bag as adsorption piece accommodating container 105 is made into thinner wall section 105a, so Kaifeng As long as part 108 is installed by handle part 109 is inserted from thinner wall section 105a, can easily carry out being received to adsorption piece and hold The assembling of device 105.
And, the handle part 109 of the part 108 that breaks a seal is that spring wire is made into coiled type, makes the coil of one end side Rolling density is close to be constituted in the coil rolling density of another side.Therefore, it is possible to gas absorption device 104 is flexibly clamped Between spring wire, make assembling reliability.
Particularly, handle part 109 is that at least one circle is in close contact and constitutes, spring force band above between making coil winding line The elastic compression for coming is strong, can strongly hold gas absorption device 104.
Therefore, Kaifeng part 108 is relative to the position skew of adsorption piece accommodating container 105 and the possibility for falling off Reduce, because assembling is fixed on assigned position, can realize that the reliability without the caused perforation error such as position skew etc. is high Gas absorption device 104.
In addition, in the Kaifeng part 108, being made into the end with the opposition side of handle part 109 of the spring wire of coiled type Portion is pressed into due to being applied in external force, and perforated portion 110 enters eleven punch 11 in being pierced into adsorption piece accommodating container 105.Now, perforated portion 110 are directly constituted using the leading section of spring wire.Therefore, because the wire rod footpath of perforated portion 110 is identical in whole length, So even if the applying mode of external force is different and deviation is produced in penetration depth, be opened in the adsorption piece of gas absorption device 104 The hole of accommodating container 105 can also turn into certain size.
Therefore, the gas around adsorption piece accommodating container 105 can not had adsorption rate deviation by gas absorption device 104 Ground, stably adsorbs, gas absorption performance stabilization, and reliability is high.
In addition, perforated portion 110 is the fore-end that will be bent from coiled type part to hub of a spool portion further to holding The lateral bend of portion 109, is formed in the perforated portion 110 of the perforate of gas absorption device 104.Perforated portion 110 is the line of online rim-shaped part Circle center, i.e. enter eleven punch 11 near the hub of a spool of handle part 109 for holding gas absorption device 104.Therefore, it is possible to anti- Only perforated as the adjacent edges without gas absorption part 106 of the periphery of gas absorption device 104 enter eleven punch 11 and slipped up, Reliable perforation can be realized.
Next, for having used the gas absorption device 104 of Kaifeng part 108 and having used its vacuum insulation part 101, illustrated for its effect and effect.
First, vacuum insulation part 101 is the gas absorber for having Kaifeng part 108 in the overcoating inside plugging in fitting of part 102 Part 104, by exhaust gas inside to vacuum after, what the bag opening portion of overcoating part 102 was heating-fusion bonded encapsulation and manufactured.
Figure 17 is the schematic diagram for illustrating the manufacture method of above-mentioned vacuum insulation part 101.Vacuum insulation part 101 is placed into In the decompression chamber 115 of vacuum packaging machine 114, using vavuum pump 116 by vacuum exhaust in decompression chamber 115.Thus, it is cladded with part Gas in 102 is vacuum exhausted and depressurizes, and the opening portion of overcoating part 102 is heat-sealed the thermal welding of machine 117, is packaged and makes Make.
Now, the Kaifeng part 108 of gas absorption device 104, due to the vacuum insulation from encapsulation of being depressurized by vavuum pump 116 Part 101 is taken out to outside the mechanicalnesses such as the atmospheric pressure external force that is applied when under atmospheric pressure or the roll-in that is carried out after encapsulation of depressurizing Power, is pressed into via the overcoating part 102 of vacuum insulation part 101, and perforated portion 110 is pierced into adsorption piece accommodating container 105, will be adsorbed Part accommodating container 105 is perforated.
Thus, the inside of gas absorption device 104 connects with the inside of overcoating part 102 of vacuum insulation part 101, gas absorption part The gas of remaining etc. is adsorbed in 106 pairs of overcoating parts 102.
Here, it is the hole of approximately fixed size because the hole opened on gas absorption device 104 does not have deviation, so The gas of remaining etc. is reliably adsorbed without the deviation of adsorption rate in overcoating part 102.Therefore, vacuum insulation part 101 can play good and stabilization vacuum insulation performance.
In addition, the Kaifeng part 108 that gas absorption device 104 is perforated will not be sent out relative to adsorption piece accommodating container 105 Raw position skew ground presses fixation by elasticity, and the adsorption piece part of adsorption piece accommodating container 105 reliably can be perforated.Institute To be also suppressed by gas absorption is bad caused by perforation error.Therefore, from this viewpoint, vacuum insulation part 101 can By the gas of ground absorption remaining etc. in overcoating part 102, so as to maintain vacuum.Thus, vacuum insulation part 101 will not cause absolutely Heat is bad, can play vacuum insulation effect high, can realize reliability high.
In addition, the reliable perforation of gas absorption device 104 can also be by making the shape of perforated portion 110 of Kaifeng part 108 Cheng Yu reaches than the outer peripheral portion of coiled type more by central part.Plus the effect, can be reliably suppressed and be led by perforation error The gas absorption of cause is bad, can more improve the reliability for vacuum insulation effect.
In addition, perforation is the gas absorption device 104 to the state being sealed in the overcoating part 102 of vacuum insulation part 101 Carry out.Therefore, it is possible to prevent from being put into after perforating in an atmosphere the situation for carrying out vacuum exhaust in overcoating part 102 again like that, will When adsorption piece accommodating container 105 is perforated, gas absorption part 106 is exposed in air in an atmosphere, is adsorbed and deteriorated, can The maintenance bond within the longer time of the gas absorption performance of gas absorption part 106 is set to be good performance.
In addition, the section that will constitute the spring wire of Kaifeng part 108 is made circle or elliptical shape, its outer peripheral face is made Arc-shaped.Therefore, even if the overcoating part 102 of vacuum insulation part 101 is pressed in the spring wire of Kaifeng part 108 due to atmospheric pressure Material, also due to the outer peripheral face of spring wire is arc-shaped, and prevents the broken bag of overcoating part 102, reliably keeps vacuum insulation The vacuum of part 101, it can be ensured that reliability.That is, if Kaifeng part 108 is formed by sheet material, in the corner of sheet material, atmospheric pressure Stress concentration readily occur at overcoating part 102, and have the possibility of broken bag.However, in the present embodiment, due to Kaifeng Part 108 is wire rod, and its outer peripheral face is arc-shaped.Thus, stress concentration will not be caused, the broken bag of overcoating part 102 is prevented from. As a result, vacuum insulation part 101 can reliably keep vacuum in a long time, it can be ensured that as vacuum insulation part 101 reliability.
In addition, the Kaifeng part 108 that gas absorption device 104 is perforated is formed by metals such as stainless steels.Thus it is possible to anti- Only the release gas in the overcoating part 102 of vacuum insulation part 101, makes the vacuum reduction in overcoating part 102, is prevented from gas The gas sorption ability of adsorption piece 106 is consumed due to adsorbing the gas.Therefore, it is possible to maintain good gas in a long time Body absorption property, makes the heat-insulating property of vacuum insulation part 101 keep good.
Further, the protective layer 112a of laminated film 112 of adsorption piece accommodating container 105 is formed by PET (poly terephthalic acids Glycol ester) or resin with PET equal following water absorption rate constitute.Thereby, it is possible to prevent from preserving gas absorption device When 104, protective layer 112a absorbs the moisture in air, and when suitable for vacuum insulation part 101, the moisture is in vacuum insulation part Release in 101 overcoating part 102, makes the vacuum reduction in overcoating part 102 or the gas sorption ability of gas absorption part 106 disappear Consumption is in the absorption of the moisture.Therefore, it can maintain gas absorption performance within the longer time, the vacuum that holding has been applicable it is exhausted The excellent heat insulating performance of warmware 101.
It should be noted that the tree of water absorption rates of the protective layer 112a more preferably using PET or with the equal following degree of PET Fat, but it is not particularly limited in these examples.
On the other hand, the vacuum insulation part 101 being thusly-formed because gas absorption device 104 is thin and with flexibility, so Can act as the vacuum insulation part 101 of several millimeters thickness degree and make the vacuum insulation part of its bending etc..That is, can realize can The vacuum insulation part not used with restricting by the form and shape of the equipment being applicable.
And, the vacuum insulation part 101 being thusly-formed can be used as the various freezings of refrigerator or automatic vending machine etc. Equipment, thermostat or thermos bottle etc. are incubated cold insulation equipment, building materials, preserve the exhausted of storage tank, the ships of ultralow temperature material such as LNG etc. Hot wall body, heat-insulating plate or adiabatic apparatus etc. are used.
(the 5th implementation method)
Next, being illustrated for the 5th implementation method of the invention.
Figure 18 is to represent the gas absorption device Kaifeng gentle body absorber of part by the 5th implementation method of the invention The top view of the mounted state of part, Figure 19 is to represent to install the gas absorption device Kaifeng gentle body absorbing elements of part The schematic diagram for representing amplification profile composition of good state.
Gas absorption device 104 in present embodiment is that porous member 118 is inserted in together with gas absorption part 106 The interior simultaneously reduced pressure sealing of adsorption piece accommodating container 105.In addition, gas absorption part 106 has with plane shape with porous member 118 The adjacent composition of state.
Here, porous member 118 is constituted, the structure with three-dimensional netted hole by sintering toner, with not The loose structure for making the powder of gas absorption part 106 pass through but pass the gas through.
In addition, porous member 118 in the manufacturing process of gas absorption device 104 due to being vacuumized, and as suction The inner surface of the laminated film 112 of annex accommodating container 105 is connected due to atmospheric pressure.In present embodiment, porous member is constituted 118 resin is made up of the hot melt property resin that the bonding layer 112c with the innermost layer as laminated film 112 has compatibility, example Such as by straight-chain low density polyethylene (LDPE) (LLDPE), high density polyethylene (HDPE) (HDPE), low density polyethylene (LDPE) (LDPE), supra polymer The resin of weight northylen (UHPE) or polypropylene (PP) etc. is constituted.Thus, porous member 118 is most interior with composition laminated film 112 The bonding layer 112c of layer is by thermal welding by physically integration.
In addition, Kaifeng part 108 is same composition with the Kaifeng part illustrated in above-mentioned 4th implementation method, but open Envelope part 108 is assembled into the chadless of porous member 118 in adsorption piece accommodating container 105.
Gas absorption device 104 as constructed as above as described above, after using vacuum extractor decompression, by sealing welding Manufacture.Now, i.e. when the bag of adsorption piece accommodating container 105 is carried out into decompression encapsulation, by from the lateral gas of porous member 118 The side of adsorption piece 106 carries out suction decompression, due to the presence of porous member 118, is prevented from gas absorption part 106 in bag from bag It is middle by unnecessarily pumping exhaust.Therefore, it is possible to not use the special device with the function of preventing gas absorption part from spilling, lead to Cross to vacuumize and manufacture, and due to vacuum pumping rate need not be slowed down can just carry out reduced pressure sealing, it is possible to making production Rate is improved, using the teaching of the invention it is possible to provide cheap gas absorption device 104.
In addition, gas absorption part 106 and porous member 118 are abutted with plane state and configured in flexible bag. Thus, compared with the situation of configuration that gas absorption part 106 and porous member 118 overlap, can make thinner, and make curved Song etc. becomes easy.Therefore, in a same manner as in the fourth embodiment, it is also possible to which the thin vacuum suitable for several millimeters or so is exhausted Warmware and bend to vacuum insulation part that arc-shaped is used etc..
And, become big by by the plane width of bag, additionally it is possible to make gas absorption part 106 while thickness of thin is kept Quantitative change is more, can in a long time maintain gas sorption ability, and the assembling of Kaifeng part 108 is also become easy, can Improve operability.
Further, since by the chadless of porous member 118 of adsorption piece accommodating container 105, so gas absorption device 104 Via the gas around in porous member 118, adsorbing.Thereby, it is possible to pass through porous member 118 aperture and porosity arbitrarily The velocity of gas sorption of setting control gas absorption part 106.Further, in overcoating part 102, by making gas absorption part 106 Adsorption rate be slower than with gas absorption device 104 in addition set moisture adsorbent adsorption rate, will can pass through for a long time The major part of contained humidity is by moisture adsorbent Adsorption in the gas that overcoating part is invaded.Therefore, it is possible to prevent gas absorption Part 106 can persistently adsorb the gas in vacuum insulation part in a long time due to being wasted caused by water adsorption.Accordingly, it is capable to Following vacuum insulation part 101 is enough realized, it can access above-mentioned productivity ratio and improve effect etc., and gas absorption can be made again Performance slows down velocity of gas sorption further without deviation ground stabilization, maintains gas sorption ability, the hair within the longer time Wave good heat-insulating property.
In addition, for the adsorption piece accommodating container 105 of gas absorption part 106, the membrane element and porous member of innermost layer 118 pass through thermal welding, i.e. constitute the laminated film 112 and porous member 118 of adsorption piece accommodating container 105 by between resin Xiang Rong, so that its entire surface is engaged all very close to each otherly.Thus, in the absence of the gas of the ambient absorption from gas absorption part 106 The situation that body is revealed from the gap between the laminated film 112 and porous member 118 for constituting adsorption piece accommodating container 105, Neng Gouti High-performance stability.Further, when the bag of adsorption piece accommodating container 105 is sealed, additionally it is possible to encapsulated in the welding for carrying out bag While, bag inner surface is engaged with the surface of porous member 118, it is also possible to improve productivity ratio.
Further, since porous member 118 by by toner sinter and is formed, porous member 118 will not because perforate when External force occur breach, be prevented from gas via breach leakage be adsorbed onto gas absorption part 106.Therefore, gas absorption part 106 The inevitable hole via porous member 118 is adsorbed to gas, can promote the stabilisation of gas absorption performance.
It should be noted that other compositions constituted with effect and vacuum insulation part 101 of gas absorption device 104 And manufacture method and effect it is identical with the 4th implementation method, omit the description.
