クト性、ブライミング容積の小さなことなどの利点があ
るため各分野で広く用いられている。The semi-permeable membrane module, which is the heart of reverse osmosis and ultrafiltration equipment, is used in six types depending on the application, and one of them, the hollow fiber type module, is compact. It is widely used in various fields because of its advantages such as high performance and small briming volume.

よ−てとりつり、製造される。This hollow fiber type module has a length of 300 to 1000 mm,
Several thousand to tens of thousands of hollow fibers with an outer diameter of 0.1 to 1 mφ are bundled together, inserted into a cylindrical case, and the ends are adhesively sealed using a non-cutting epoxy adhesive. After curing, the ends are opened and trimmed/recessed, and a cap is attached by gluing, explosive bonding, or screwing, and manufactured.
（従来技術）
従来、中空糸型モジュールの端部を接着層とするために
は主としてエポキシ系接着剤が単独で使われている。(Prior Art) Conventionally, epoxy adhesives have been used alone to form adhesive layers at the ends of hollow fiber modules.

歪が蓄積されることになる。(Problems to be Solved by the Invention) However, since this epoxy adhesive generates a large amount of self-heating during curing, if it is used in a loud environment, it will produce a temperature of 1 [5+ cloth]; it will cause uneven curing. As a result, strain is accumulated inside the cured adhesive at L7.

きくなり、ケースと接着剤との剥離が生じるなどの問題
があった。In addition, epoxy adhesives are non-reflexible and have a relatively large shrinkage rate, so a large amount of adhesive is used especially in large-diameter hollow fiber modules, which inevitably leads to large internal distortions. There were problems such as the case becoming hard and the adhesive peeling off from the case.

ラブルを招来する。Peeling off such a case and adhesive 11! The case and adhesive expand when exposed to temperature changes not only during module manufacturing but also during use, especially when heat sterilization is performed or cold water is used to process and clean relatively high-temperature liquids. There were many cases where peeling occurred due to the difference in shrinkage rate. Such peeling of the hollow fiber type module causes a fatal trouble in practical use.

浄するのに長時間を要することになる。This is because, in a system that uses many hollow fiber modules, if even just one module is in this condition, it will be difficult to find the problem, and even if the leaking module is replaced, it will be difficult to repair the contaminated system. It will take a long time to clean.

テム全体に汚染が拡大するため、特に問題が大きい。This is a particularly serious problem in liquid processing equipment used for sterilization purposes, as even the slightest leak can result in the proliferation of loose seals, spreading contamination throughout the system.

械的な衝撃に対する耐久力を保持させたことにある。, □Omg) 'That is, in the present invention, one cylindrical case is completely filled with a hollow fiber bundle, and the ends of the hollow fiber bundle and the case end are adhesively sealed. It is a hollow fiber type module, and the adhesive composition in the cross section perpendicular to the module length direction of the adhesive sealing part is a non-flexible adhesive, a flexible adhesive, The key point of the present invention is that the adhesive sealing portion of the hollow fiber type module, especially the cylindrical At the adhesive sealing part with the case, the flexible liquid agent is sandwiched between non-flexible adhesives to create an annual ring-like structure that maintains the adhesion between the case or hollow fibers and the adhesive layer, making it flexible. The elasticity of the adhesive allows it to maintain durability against thermal shock and mechanical shock.

欠点をおぎない、お互いの利点を生かしたため耐熱性、
耐熱衝撃性が大きく向上した。When a thermal shock is applied to a hollow fiber module, the case and adhesive layer expand and contract repeatedly, and even if the adhesive has heat resistance, if it is a non-OJ flexible adhesive, the elasticity of the adhesive layer itself will increase. Since there is very little f'L, it is unable to absorb the impact, and eventually the case and adhesive layer peel off. In addition, although flexible adhesives can absorb thermal shock, many of them lack adhesive strength with the case, which is a dissimilar material, when heated at high temperatures. However, even if a flexible adhesive has a weak adhesion to the case at this high temperature, when adhering to the same type of material (adhesive and adhesive), even if the adhesive is different, the adhesion will be the same as the case. Since the adhesive strength is very large compared to when adhering to different types of materials, the adhesive force at high temperatures is hardly affected. Therefore, when adhering to a case made of a material different from the adhesive layer or a hollow fiber, a non-OJ
! l? ! The hollow fiber module of the present invention, which uses a flexible adhesive and a flexible adhesive to bond the adhesives together, overcomes the drawbacks of both adhesives and takes advantage of the advantages of both, resulting in heat resistance, heat resistance,
Thermal shock resistance has been greatly improved.

キシ糸接着剤などが選けれる。In the present invention, the non-flexible adhesive used to bond only the ends of the hollow fiber bundle or only the case may be a conventional epoxy adhesive with high heat resistance. Flexible adhesives for the purpose of absorbing impact include adhesives with cured VK flexibility, specifically adhesives with siloxane bonds, epoxy thread adhesives with natural comb or synthetic comb skeletons, An epoxy thread adhesive with a timer acid beak can be selected.

Particularly preferred are those. Note that the stretch wheel of the epoxy thread adhesive, which is a non-flexible layering agent, is about 5% thick at most.

Lacks pressure resistance. Therefore, the thickness of the hollow fiber type Modineal, especially the inner diameter of the case and the filling tfI4
Although it depends on the filling rate of the hollow fibers to be zapped, it is preferably 1 to 5.
贅だケースと可撓性接着剤にはさまれている非可撓性接

好ましい。The purpose of this part is NO to improve the adhesion between the case and the flexible adhesive layer at high temperatures, so if this layer is thick, it will not easily deform by itself, which is a disadvantage of non-flexible adhesives. If the VC is strongly affected), the thermal and mechanical shock VC will be weakened, and there is a risk that the VC will separate from the case. Therefore, the thickness of this layer is preferably 2 mm or less, although it depends on the hardness of the adhesive itself.
