Description
Technical field
The present invention relates to a kind of heat-insulated pipe coating, its body is made up of glass fibre, relates in particular to a kind of heat-insulated pipe coating that can be used for all pipeline heat insulators, regardless of its external environment.
Background technique
Korean patent No. 274314 discloses a kind of employing glass fibre and has made the tectal method of heat-insulated pipe, and its franchise is in the applicant.
A kind of do not have the high-density tube coating of cut according to this method manufacturing, it is to use Bond on the glass fiber mat of a kind of needle punching, on shaping roller, twine glass fiber mat, and the puck of use high speed rotating is pressed into the glass fiber mat of winding.This pipe coating is considered to good pipeline insulation product, but a lot of shortcomings are arranged.Specifically be exactly,,, threatening people's health Guan coating is inconvenient to install and remove because harmful glass fibre is exposed to the outside, and nonsensical as a product.
In addition, the pipe coating must cover with an extra external cap before installation, has caused the increase of installation cost.And, can not use out of doors owing to manage coating itself, and not have cut, the pipeline that it can not be used for having laid.
If the pipe coating cuts in half by shearing process quilt, then can be installed on the pipeline of having laid.Yet when this kind situation, transportation and mounting or dismounting are difficulty more, and more multiplex (MUX) people and more time install, and because the tectal two halves of pipe must be linked together by band or silk thread, trouble thereupon.
In addition, comprise rain and snow when being exposed to, or when external factor such as leaking, the insulating characteristics of glass fibre will be lost owing to high-hydroscopicity, the safety that the weight of pipeline increases institute's installation apparatus produces adverse influence, and the moisture that absorbs causes pipeline corrosion, has shortened the life-span of pipeline.
Therefore, for the indoor pipeline that does not have the water intrusion risk, has only very limited purposes as the pipe coating of thermoinsulation material.In the pipeline construction of oil refinery and industrial treatment factory, seldom use the pipe coating.Because these problems are made the pipe coating and can not be look to having high profit.In addition, the Consumer does not select except using traditional molded perlite or silica product, and these products have a lot of shortcomings, for example fitting operation, insulating characteristics, volume, weight, intensity and mounting cost, will be as the heat insulator of pipeline, they are also had any problem at cost with aspect safeguarding.Therefore, be necessary to develop the tectal substitute products of conventional tube.
Summary of the invention
Therefore, the present invention makes in view of the above problems, an object of the present invention is to provide a kind of heat-insulated pipe coating, this product has use value, convenient mounting or dismounting and installing can be used for the pre-pipeline of installing, even also can be as thermoinsulation material under rugged environment very.
In order to realize above-mentioned purpose of the present invention, a kind of heat-insulated pipe coating is provided, comprise a pipe coating body by the glass fibre shaping, comprise two half-cylindrical sheets; One aluminium foil around the body adhesion; It is characterized in that: body is cut into two half-cylindrical sheets in central authorities, and aluminium foil twines two half-cylindrical sheets since a central cutting surface.And a kind of Bond and body that contains an amount of coating agent combined closely, and being shaped like this is in order to give the body water proofing property.
Description of drawings
From finding out above and other objects of the present invention, characteristics and other advantages significantly to the detailed description of the preferred embodiment of the present invention, in the accompanying drawings below in conjunction with accompanying drawing:
Fig. 1 is the tectal perspective view of heat-insulated pipe according to an embodiment of the invention;
Fig. 2 is the tectal side cross-sectional view of heat-insulated pipe shown in Figure 1;
Fig. 3 is that heat-insulated pipe coating shown in Figure 1 is installed in the side cross-sectional view on the pipeline;
Fig. 4 is a pipe coating body shown in Figure 1 side cross-sectional view when being shaped;
Fig. 5 is the tectal perspective view of heat-insulated pipe according to another embodiment of the present invention;
Fig. 6 is the tectal side cross-sectional view of heat-insulated pipe shown in Figure 5.
Embodiment
Fig. 1 and Fig. 2 are respectively tectal perspective view of the heat-insulated pipe of one example according to the present invention and side cross-sectional view, and Fig. 3 is that the heat-insulated pipe coating is installed in the side cross-sectional view on the pipeline, the side cross-sectional view when Fig. 4 is the shaping of pipe coating body.
Referring to figs. 1 to Fig. 4, a kind of Bond and the continuous glass-fiber felt 2 that contain an amount of coating agent are combined closely, glass fiber mat 2 is wrapped on the shaping roller 4, the glass fiber mat that twines is to use puck 6 high speed rotating to be pressed into, and the glass fiber mat that is pressed into is dried and discharges and forms the tectal body 8 of pipe.Then, body 8 therefrom is cut to two halves, aluminium foil 10 be bonded at 8 liang of cutting parts of body around.
Being used for the glass fiber mat 2 of forming body 8 vertically is shaped by glass fibre, and to make it having only thickness and width, the preferred pin acupuncture manipulation is so that it has high density.
Bond is a kind of mixture, by a kind of silication Bond, and a kind of fluorine-based coating agent (SWR430), a kind of strengthening agent and water mix formation with proper proportion.Repetition test confirms that the proper mixture ratio example is: the silication Bond of 10～30% volume contents, the coating agent of 1～10% volume content, the water of the strengthening agent of 1～10% volume content and 50～88% volume contents.
If mixing uses the volume of coating agent less than 1%, then do not satisfy the requirement of water proofing property.On the other hand, if the volume content that mixes with coating agent surpasses 10%, the chemical reaction that the fluorine content of increase causes can reduce water proofing property, considers that fluorine-based coating agent is relatively more expensive, and excessive use coating agent also causes economic burden.Therefore, the amount of the coating agent of interpolation is preferably in the above-mentioned scope and selects.
As for strengthening agent, mainly use a kind of thermoplastic resin.When the volume content of strengthening agent less than 1% the time, do not reach the intensity that needs.Equally, when the volumetric usage of strengthening agent surpassed 10%, intensity was to have satisfied, but when heat-insulating cover was used as thermoinsulation material under the high temperature, the risk of breaking out of fire had increased.Therefore, the amount of the strengthening agent of interpolation is preferably in the above-mentioned scope and selects.But, strengthening agent is not necessary component, and these are different with coating agent.
Bond can or pass by spray and contain the Bond plating bath and glass fiber mat is combined closely simply, and this is better than coiled shape cylinder coiling glass fiber mat.At this moment, Bond dehydrating amount when considering high speed rotating pressure forming, Bond consumption are preferably more than the necessary consumption of bonding.Used binder amount can be regulated easily by the feed speed of control glass fiber mat.
Shaping roller is selected according to the inner diameter and the length of body 8.For the ease of the release of glass fiber mat, preferably use a kind of releasable material, and before coiling glass fiber mat 2, a chuck is installed.
Can control by using a kind of encoder owing to be wound on the consumption of the glass fiber mat 2 on the shaping roller 4, thereby this encoder is possible on the technology based on the density feeding certain-length of every square metre of glass fiber mat.Preferably, the edge of glass fiber mat is wiped natural shaped by brush.
Behind coiling glass fiber mat 2, puck 6 contacts under suitable pressure with the glass fiber mat 2 that twines, thereby and is pressed into glass fiber mat 2 along with shaping roller 4 rotates together.At this moment, excessive Bond is dehydrated, and glass fiber mat is shaped by the strong adhesive force that causes owing to pressurization.
Be pressed into the back to the glass fiber mat drying, coating discharges from shaping roller then.Air dry or the vacuum drying of use dryer all are feasible, but consider speed and uniformity, preferably use vacuum drying.After the drying, the glass fiber mat of shaping discharges from shaping roller, thereby obtains a pending pipe coating body.
Pending body cuts in half in the centre after carrying out surface treatment, is cut length to needs by side then, thereby obtains pipe coating body 8.Carry out central authorities' cutting before side is cut, in this step, some part of body both sides preferably is not cut off, and makes this physical efficiency keep integrity, cuts until follow-up side.
The advantage that body is complete is to make things convenient for side to cut and aluminium foil 10 is adhered on the body.
After aluminium foil 10 adheres to, preferably then carry out side and cut.In order to adhere to, around body 8, use Bond, aluminium foil 10 is sticked to body since a central cutting planes then around.
The width of aluminium foil 10 is greater than the length of heat-insulated pipe coating A, thereby the tool cutting edge plane is smooth when keeping side to cut.Be exactly that the width of aluminium foil 10 is compared the length of heat-insulated pipe coating A and extended about 30～70mm, forms an adhesion section 12 specifically.The extension of this aluminium foil 10 width can be simplified installation, makes the thermal loss minimum of back by central cutting surface is installed.
Because aluminium foil 10 itself has low tensile strength, a kind of glass fibre preferably is used as adhesive, to increase the tensile strength of aluminium foil.
After the abundant drying of Bond, carry out side and cut, the size cutting that dual-side is all predetermined according to heat-insulated pipe coating A.
Fig. 5 and Fig. 6 are respectively tectal perspective view of heat-insulated pipe and side cross-sectional view according to another embodiment of the present invention.If possible, central cutting planes 14 preferably is angle shape or curvecd surface type.There is one bonding protruding 16 and one bonding groove 18 in each side tangent plane, and the heat-insulated pipe coating is fitted to each other.
Angle from glass fibre processability and existing cutting technique, it is difficult that processing has the angle shape of bonding projection and bonding groove or curvecd surface type central authorities' cutting planes and side tangent plane, but also help strengthening contacting between cutting surface and heat-insulated pipe coating A, make thermal loss reach minimum.
Because the two halves of body 8 are linked together by aluminium foil 10, pipe coating of the present invention is suitable for mounting or dismounting and installs.
Again referring to figs. 2 and 3, next step is exactly a pipe coating A is installed on the pipe B.At first, a central cutting part opens greatly, is enough to containing pipe B.Then, the two ends of aluminium foil 10 are overlapping and glue formation bonding portion 12 with two-sided tape.Thereby the heat-insulated pipe coating can be easy to be installed on the pipeline that has laid.And because aluminium foil 10 surrounds the tectal body 8 of pipe, glass fibre is not exposed to the outside, thereby heat-insulated pipe coating of the present invention has the use value as product, can install out of doors.
On the other hand, combine, make it have good water proofing property, can resist pipe B and go up the leakage of managing B behind the mounting pipe coating and ooze owing to constitute glass fibre and the coating agent of pipe coating body 8.
Because glass fibre is a waterproof, there is not the risk of insulating characteristics loss here, whether operator can discern rapidly and seep water or where seep water.
When infiltration takes place, the heat-insulated pipe coating also because of around the complete basically waterproof of existence of aluminium foil 10.Although seep water, current are through being formed in the groove on the heat-insulated pipe coating A.Thereby water can be mild outer spilling out, thereby whether operator can discern rapidly and seep water or where seep water.
Under the situation of pipe coating of the present invention as the thermoinsulation material of outdoor pipeline installation, the pipe coating is exposed in the external environment, comprises rain and snow.Because aluminium foil 10 will be managed coating and external environment is isolated fully, therefore do not exist water by being formed in the risk that the supratectal groove of pipe flows into.Although there is a spot of water to flow into, the pipe coating also can because of its good water proofing property as thermoinsulation material.
In addition, because heat-insulated pipe coating of the present invention is by extremely light made, fast dewatering becomes possibility when making infiltration, and in the place that the pipe coating is installed, equipment does not have the risk of overload, thereby has guaranteed the Security of equipment.And because heat-insulated pipe coating of the present invention has greatly reduced the corrosive pipeline that is caused by water, the life-span of pipeline has prolonged.
Find out obviously that from top description heat-insulated pipe coating of the present invention has use value as a kind of product, by twine aluminium foil around pipe coating body, it is convenient to mounting or dismounting and installs.
In addition, because the tectal body openings of heat-insulated pipe is even as big as holding a pipeline, and around pipe bonding, the heat-insulated pipe coating is installed easily, on the pipeline that can be used to lay.
Further and since the heat-insulated pipe coating by coating agent to the mounting pipe coating after the leakage of the pipeline water proofing property of oozing make can fast dewatering, do not have the risk of insulating characteristics loss and apparatus overload, thereby guaranteed the Security of equipment.
In addition, because glass fibre is not exposed to the outside, the heat-insulated pipe coating can be installed out of doors.And, have high water proofing property owing to the heat-insulated pipe coating uses coating agent, and it is waterproof to use aluminium foil to make, it can be used as the thermoinsulation material of oil refinery and industrial treatment factory pipeline.Therefore, by increasing the tectal consumption of heat-insulated pipe, can expect to obtain high benefit.And because the heat-insulated pipe coating can substitute conventional insulation material-perlite or silica product, it is all no problem in all respects, for example mounting cost and maintenance.
Although for purpose of description discloses the preferred embodiments of the present invention, those of ordinary skill in the art should be appreciated that when not breaking away from claims of the present invention scope of disclosure and essence, allows different changes, augments and replaces.
