Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Referring to Fig. 1, it is the sectional view of the double shielding bag of first embodiment of the invention；As shown, the present embodiment
A kind of double shielding bag 1 for cortina assembling is provided, the double shielding bag 1 of the present embodiment is used for cladding wire membrane structure, works as dress
When the cortina structure of double shielding bag 1 is filled in partition, double shielding bag 1 can protect cortina structure to avoid during filling in
Friction is generated with partition, cortina structure is caused to generate damage.The double shielding bag 1 of the present embodiment includes protection bag body 10, protection
Bag body 10 has the first film layer 101 and the second film layer 102, and the first film layer 101 has first end 101a and second end 101b, the
One end 101a have opening 103, second end 101b have sealing 104, that is, the first film layer 101 first end 101a not
If the second end 101b of the first film layer 101 has opening, in other words, the opening of the first end 101a of the first film layer 101 passes through
Sealing 104 seals.Second film layer 102 is set in the first film layer 101, and the first film layer 101 is located at the interior of the second film layer 102
Side, one end of the second film layer 102 is melted by heat or other modes are connected to the second end 101b of the first film layer 101, the second film layer
102 separate with the first film layer 101, have between the second film layer 102 and the junction and sealing 104 of the first film layer 101 and cut
Area 105.The material of first film layer 101 of the present embodiment can in the present embodiment identical or not identical as the material of the second film layer 102,
First film layer 101 and the second film layer 102 are polytetrafluoroethylene (PTFE) (PETF) film.Since the shell of oxygenator or the material of partition are adopted
With polycarbonate (PC) material etc., the material of cortina structure is polypropylene (PP) hollow-fibre membrane etc., to reduce protective bag and partition
And the friction between cortina structure, protect bag body 10, the optional polytetrafluoroethyl-ne of the material of the first film layer 101 and the second film layer 102
Alkene, polytetrafluoroethylene (PTFE) (Polytetrafluoroethylene, PETF), is abbreviated as teflon, commonly referred to as " non-sticking lining ".
Polytetrafluoroethylene (PTFE) has the characteristics that antiacid alkali resistant, resists various organic solvents, is practically insoluble in all solvents.Meanwhile polytetrafluoro
Ethylene has the characteristics that resistant to high temperature, its coefficient of friction is extremely low, can make lubricating action.
Fig. 2 to Fig. 5 is please referred to, is the usage state diagram of the double shielding bag of first embodiment of the invention；As shown,
When the double shielding bag 1 of the present embodiment is used for the assembling of cortina structure 2, cortina structure 2 is first placed in protection bag body from opening 103
In 10, one end that protection bag body 10 has opening 103 is then tightened by tightening piece 3, in the present embodiment, tightening piece 3 is by first
Film layer 101 and the second film layer 102 are tightened simultaneously, or the first film layer 101 is only tightened in selection, is repeated no more in this, wherein tightening
Part 3 includes rubber band, fastening straps or adhesive tape.Then the cortina structure 2 loaded on double shielding bag 1 is reduced by squeezing compression
The volume of cortina structure 2, make cortina structure 2 diameter be less than partition 4 internal diameter, by compressed cortina structure 2 fill in every
In plate 4, there is one end of opening 103 to expose respectively from the both ends of partition 4 for sealing 104 and protection bag body 10, protect bag body 10
Between cortina structure 2 and partition 4.After the cortina structure 2 loaded on double shielding bag 1 is filled in partition 4, it is necessary to will be double
Layer protective bag 1 is extracted out between cortina structure 2 and partition 4.It is double-deck from being extracted out between cortina structure 2 and partition 4 in the present embodiment
The method of protective bag 1 be first removal sealing 104, i.e., from sealing close 104 and second film layer 102 and the first film layer 101 connection
Between the area 105 that cuts cut, make secrecy bag body 10 second end 101b have opening 103, while be located at junction
The second film layer 102 one end still with the first film layer 101 keep connect.Then tightening piece 3 is released, from the first of protection bag body 10
It holds 101a to pull the second film layer 102, makes the second film layer 102 that the first film layer 101 be driven to open relative to cortina structure 2, i.e., first
Film layer 101 is driven by the second film layer 102 and is detached from cortina structure 2 at leisure in peel way, as shown in fig. 6, avoiding first
Film layer 101 and cortina structure 2 generate friction, and cortina structure 2 is avoided to generate damage because of friction.
Referring to Fig. 7, it is the usage state diagram of the double shielding bag of second embodiment of the invention；As shown, this reality
The double shielding bag difference of the double shielding bag 1 and above-described embodiment of applying example is, in the present embodiment, the second film layer 102 is opposite
It is protruded in one end that it is connected with the first film layer 101 from the first end 101a of the first film layer 101, in other words, the present embodiment
One end for not connect with the first film layer 101 of the second film layer 102 be not aligned with the first end 101a of the first film layer 101, extracting out
When double shielding bag 1, user easier can direct pull the second film layer 102, avoid user pull the first film layer 101 and
Cortina structure 2 is caused to generate damage because rubbing with the first film layer 101.
In conclusion the present invention provides a kind of double shielding bag and application method for cortina assembling, the present invention is used
Double shielding bag protects cortina structure, and the cortina structure loaded on double shielding bag passes through pulling double shielding bag loaded in partition
Outer membrane drive inner layer film to remove from cortina structure, avoid inner layer film and cortina structure from generating friction, and then prevent cortina
Structure generates damage because of friction.
