本発明は中空糸型モジユールの製造方法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for manufacturing a hollow fiber module.
（従来技術）
従来から中空糸型モジユール端部の接着封止に
は主としてエポキシ系の接着剤が使われている。(Prior Art) Epoxy-based adhesives have traditionally been used to adhesively seal the ends of hollow fiber modules.
（発明が解決しようとする問題点）
しかし、この接着剤は硬化時自己発熱が大きい

糸端部と接着部界面での亀裂が生じ、モジユール
のリークの原因になるという問題があつた。(Problems to be Solved by the Invention) However, since this adhesive generates a large amount of self-heating during curing, when used in large quantities, temperature distribution occurs, resulting in uneven curing. At this time, strain will be accumulated inside the cured adhesive. In addition, epoxy adhesives have a relatively large shrinkage rate when cured,
In addition, when making a large diameter hollow fiber module,
Since a large amount of adhesive is used, the internal distortion becomes large, causing problems such as peeling of the adhesive from the case edge or cracks at the interface between the hollow fiber end and the adhesive, which can cause module leaks. It was hot.
このような問題を解決するために、同じような

い。 In order to solve this problem, a similar annular body is used, an O-ring is fitted into this annular body, and the O-ring is connected to the case without adhesive. A method has been proposed for making a seal. However, in this system, the vicinity of the O-ring becomes a liquid retention area, and since the hollow fiber module is often used especially for sterilization, problems such as bacterial growth are not solved.
また、使用する接着剤の量が多いと接着剤硬化
時の温度上昇と温度分布を抑えるためには硬化に
長時間を要し、生産性にも影響をおよぼすことに
なる。 Furthermore, if a large amount of adhesive is used, it will take a long time to cure the adhesive in order to suppress the temperature rise and temperature distribution during curing, which will also affect productivity.
このような状況に鑑み、本発明者らは鋭意検討
した結果、本発明を完成させた。 In view of this situation, the present inventors have completed the present invention as a result of intensive studies.

ジユールの製造方法。」である。(Structure of the Invention) That is, the present invention provides a method for filling a cylindrical case with a hollow fiber bundle and sealing the ends of the hollow fiber bundle and the case and between the ends of the hollow fibers with an adhesive. In a method for manufacturing a hollow fiber module, a ring-shaped body having an outer diameter smaller than the inner diameter of the case is fitted into the end of the case, and the end of the hollow fiber bundle is inserted into the ring-shaped body. A method for manufacturing a hollow fiber module, characterized in that the parts between the part and the annular body, the annular body and the end of the case, and the ends of the hollow fiber bundle are sealed with an adhesive. .
本発明のポイントは接着剤が充填される空間を
環状体により体積置換して接着作業時に使用する
接着剤の量を少なくすることにある。 The key point of the present invention is to reduce the amount of adhesive used during bonding work by replacing the volume of the space filled with adhesive with an annular body.

空糸間端部を接着封止している接着剤である。 FIG. 1 is a schematic cross-sectional view showing the state of adhesive sealing of the end of a hollow fiber module by the method of the present invention using an annular ring, in which 1-1 is a cylindrical case;
-2 is the space between the cylindrical case and the yarn bundle, 3-3
is the adhesive filled in the end of the space 2-2,
4-4 is an annular body, 5-5 is one of many hollow fibers,
Reference numeral 6-6 indicates a hollow portion of the hollow fiber 5-5, and reference numeral 7-7 indicates an adhesive for bonding and sealing the ends between each hollow fiber.

た接着剤の内部に蓄積される歪が少なくなり、前
述のような問題が解決される。 In this way, the space that would normally be filled with adhesive will be occupied by an annular ring with a certain volume that has already been strained, just like hardened adhesive.
As a result, the amount of adhesive injected in the bonding process, particularly the amount of adhesive injected into the outer periphery of the hollow fiber bundle, can be reduced. Therefore, the strain that inevitably accumulates inside the cured adhesive is reduced, and the above-mentioned problems are solved.
本発明において使用する環状体としてはプラス
チツクの成型品またはパイプの切断品などが適切
で、プラスチツクの材質としては熱硬化性のも
の、熱可塑性のものいずれでも用いることができ
る。特に用いる接着剤と同材質の成型品であれば
好都合である。 The annular body used in the present invention is suitably a molded plastic product or a cut pipe product, and the plastic material may be either thermosetting or thermoplastic. In particular, it is convenient if it is a molded product made of the same material as the adhesive used.
また、強化剤として繊維をはじめとする充填材
が含まれているものでもよいし、表面が適度に粗
化されているものでもよい。 Further, the material may contain a filler such as fiber as a reinforcing agent, or may have an appropriately roughened surface.
用いる環状体のサイズはその外径が円筒状ケー
スの内径よりもわづかに小さく、且つケースとの
間をスムーズにスライドさせることができる程度
のものがよい。 The size of the annular body to be used is preferably such that its outer diameter is slightly smaller than the inner diameter of the cylindrical case and that it can be slid smoothly between the annular body and the case.
一方、環状体の内径は充填される中空糸束の太
さにもよるが、通常は外径の90％程度が適切であ
る。また環状リングの長さは接着封止部よりやや
短か目程度が好ましく、通常10〜50mm、好ましく
は20〜30mmである。 On the other hand, the inner diameter of the annular body depends on the thickness of the hollow fiber bundle to be filled, but usually about 90% of the outer diameter is appropriate. The length of the annular ring is preferably slightly shorter than the adhesive sealing portion, and is usually 10 to 50 mm, preferably 20 to 30 mm.

It can also be used in combination with a cylindrical case as disclosed in Japanese Utility Model Application No. 59-104128.
（発明の効果）
ａ 接着剤使用量を下げたことにより、接着剤の
自己発熱を抑制し、硬化むらが少なくなつた。(Effects of the invention) a By reducing the amount of adhesive used, self-heating of the adhesive was suppressed, and curing unevenness was reduced.
ｂ 接着する部分の径が減少したので収縮が少な
くなつた。b Shrinkage was reduced because the diameter of the bonded part was reduced.
ｃ 環状体が接着剤の中に埋め込まれるので接着
部分が複合材料のようになり強度が上がる。c Since the annular body is embedded in the adhesive, the bonded part becomes like a composite material and its strength increases.
ｄ 糸束とケースとの間に環状体が介在すること
により、剥離が最も起こり易い部分、即ちケー
スの内周付近において糸束に付与されている保
湿剤による悪影響がなくなる。(d) By interposing the annular body between the yarn bundle and the case, the harmful effect of the humectant applied to the yarn bundle is eliminated in the area where peeling is most likely to occur, that is, near the inner circumference of the case.
ｅ 接着工程において使用する接着剤が少なくな
るので硬化に要する時間を短縮することがで
き、生産性が改善される。e Since less adhesive is used in the bonding process, the time required for curing can be shortened, improving productivity.
ｆ Ｏ−リングを用いてシールされているモジユ
ールのように液が滞留するデツドスペースがな
い。f There is no dead space for liquid to accumulate, unlike modules that are sealed using O-rings.
