Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、中空糸型膜モジュールの製造方法に関する。TECHNICAL FIELD The present invention relates to a method for manufacturing a hollow fiber membrane module.
さらに、詳しくは、中空糸束端部の接着方法に関する。More specifically, the present invention relates to a method for adhering ends of hollow fiber bundles.
逆浸透法や限外過法装置の心臓部である半透膜モジュ
ールは用途に応じて各種の型式のものが用いられてお
り、その中の１つである中空糸型モジュールはそのコン
パクト性、プ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。Various types of semipermeable membrane modules, which are the heart of the reverse osmosis method or the ultrafiltration apparatus, are used depending on the application, and the hollow fiber type module, which is one of them, is compact, It is widely used in various fields because of its advantages such as small priming volume.
（従来技術及び問題点） 中空糸膜モジュールの製造方法において、中空糸束端部
の接着にはエポキシ接着剤またはウレタン接着剤が用い
られている。(Prior Art and Problems) In the method for manufacturing a hollow fiber membrane module, an epoxy adhesive or a urethane adhesive is used for bonding the ends of the hollow fiber bundle.
しかし、多くは遠心シール機によってポッティングされ
る。However, most are potted by centrifugal sealing machines.
これは、接着剤を中空糸束中の中空糸相互間または中空
糸内に確実に入れるためと、中空糸束中の中空糸相互間
への接着剤のはい上がりを防ぐためである。This is to ensure that the adhesive is put between the hollow fibers in the hollow fiber bundle or in the hollow fibers, and to prevent the adhesive from rising to the hollow fibers in the hollow fiber bundle.
遠心シール機を使用すると確実な接着は容易であるが、
遠心シール機の費用あるいははんざつな取りつけ取りは
ずし作業がともない、作業時間を比較的要する欠点があ
る。If you use a centrifugal sealing machine, reliable adhesion is easy, but
The centrifugal sealing machine has a drawback that it requires a relatively long working time due to the cost or the tedious mounting and dismounting work.
一方遠心シール機を使用しないで接着剤中に中空糸束端
部を浸漬すると中空糸相互間への接着剤のはい上がりを
生じ、確実な接着が難しい。特に中空糸材質が接着剤と
比較的ぬれ性のよいポリスルホン系樹脂またはポリエー
テルスルホン系樹脂の場合などは、激しいはい上がりを
生じることが多い。On the other hand, if the ends of the hollow fiber bundles are immersed in the adhesive without using a centrifugal sealing machine, the adhesive will rise between the hollow fibers, making reliable adhesion difficult. In particular, when the hollow fiber material is a polysulfone-based resin or a polyethersulfone-based resin that has a relatively good wettability with the adhesive, a sharp rise often occurs.
また、はい上がりを生じない様な非常に粘調な接着剤を
用いると、中空糸相互間へ接着剤が入りにくくなってし
まう。Further, if an extremely viscous adhesive that does not cause rising is used, it becomes difficult for the adhesive to enter between the hollow fibers.
この様な状況を鑑み、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 such a situation, as a result of intensive studies by the present inventors,
The present invention has been completed.
（問題点を解決するための手段） 即ち、本発明はエポキシ接着剤またはウレタン接着剤中
に中空糸束端部を浸漬する中空糸束端部封止において、
中空糸束がポリエーテルスルホン系樹脂またはポリスル
ホン系樹脂でできており、 エキポシ接着剤またはウレタン接着剤の硬化反応率が10
〜50％または硬化反応が始まってから15分以上経過した
後、中空糸束端部をこれらの接着剤中に浸漬することを
特徴とする中空糸束端部接着方法である。(Means for Solving Problems) That is, the present invention relates to hollow fiber bundle end sealing in which a hollow fiber bundle end is immersed in an epoxy adhesive or a urethane adhesive,
The hollow fiber bundle is made of polyethersulfone resin or polysulfone resin, and the curing reaction rate of epoxy adhesive or urethane adhesive is 10
The method for adhering the ends of hollow fiber bundles is characterized by immersing the ends of the hollow fiber bundles in these adhesives after ˜50% or 15 minutes or more after the curing reaction has started.
本発明による中空糸束端部接着方法は、エポキシ接着剤
またはウレタン接着剤をある程度反応させておいて後、
中空糸束端部を浸漬することで、はい上がりの激しいポ
リエーテルスルホン系樹脂またはポリスルホン系樹脂で
できた中空糸を確実に接着できることにある。The hollow fiber bundle end portion bonding method according to the present invention is a method in which an epoxy adhesive or a urethane adhesive is reacted to some extent,
By immersing the end portion of the hollow fiber bundle, it is possible to reliably bond a hollow fiber made of a polyether sulfone resin or a polysulfone resin that rises sharply.
ポリエーテルスルホン系樹脂またはポリスルホン系樹脂
でできた中空糸は、エポキシ接着剤やウレタン接着剤と
比較的ぬれ性が良好で一般に接着しやすい。しかし、中
空糸束端部接着のような充填接着の場合は、ぬれ性が良
好であると、中空糸の壁面にそって接着剤がはい上がる
現象が激しくおこる。Hollow fibers made of polyethersulfone-based resin or polysulfone-based resin have relatively good wettability with epoxy adhesives and urethane adhesives and are generally easy to bond. However, in the case of filling adhesion such as adhesion of hollow fiber bundle ends, if the wettability is good, the phenomenon in which the adhesive rises along the wall surface of the hollow fiber occurs severely.
その結果、充填したい部分の接着剤が不足し、中空糸と
中空糸間に空洞を生じることになる。As a result, the adhesive in the portion to be filled becomes insufficient, and a cavity is created between the hollow fibers.
また、接着剤のはい上がりにより、中空糸の有効面積も
小さくなってしまう。Further, the rise of the adhesive also reduces the effective area of the hollow fiber.
これを防ぐためには、中空糸と接着剤のぬれ性をある程
度悪くするか、または接着剤が中空糸をはい上がる時間
をなくすることが必要である。In order to prevent this, it is necessary to make the wettability of the hollow fiber and the adhesive worse to some extent or to eliminate the time for the adhesive to push up the hollow fiber.
エポキシ接着剤またはウレタン接着剤は、硬化反応によ
り、接着剤中の分子は徐々に高分子になってくる。The molecules of the epoxy adhesive or urethane adhesive gradually become a polymer due to the curing reaction.
すると、粘度も高くなり中空糸とのぬれ性が悪くなる。Then, the viscosity also increases and the wettability with the hollow fiber deteriorates.
また、ある程度反応させていると、流動性を失うまで時
間を要せず中空糸束端部を浸漬しても大きなはい上がり
を生じない。Further, if the reaction is carried out to some extent, it does not take time until the fluidity is lost, and even if the end of the hollow fiber bundle is immersed, a large rise does not occur.
本発明においては、エポキシ接着剤またはウレタン接着
剤の硬化反応率が10〜50％または硬化反応が始めてから
10分以上経過することが必要である。In the present invention, the curing reaction rate of the epoxy adhesive or the urethane adhesive is 10 to 50% or after the curing reaction starts.
It is necessary to pass 10 minutes or more.
硬化反応率が50％をこえると、接着剤はゲル状になって
しまい、中空糸束を浸漬することができなくなってしま
う。If the curing reaction rate exceeds 50%, the adhesive becomes a gel and the hollow fiber bundle cannot be dipped.
本発明の中空糸束端部接着方法は、中空糸束端部の中空
糸相互間の接着のみばかりでなくケースと中空糸束端部
または中空糸相互間の接着もできる。The method for adhering ends of hollow fiber bundles of the present invention can not only adhere the hollow fibers at the ends of the hollow fiber bundles to each other, but can also adhere between the case and the ends of the hollow fiber bundles or between the hollow fibers.
しかし、ぬれ性が少し悪いため、中空糸相互間へ大量の
接着剤を注入する場合においては難しい。However, since the wettability is a little poor, it is difficult to inject a large amount of adhesive between the hollow fibers.
したがって、一般には中空糸束端部の中空糸相互間のみ
の接着に用いるのが好ましい。Therefore, it is generally preferable to use it for bonding only the hollow fibers at the ends of the bundle of hollow fibers.
（発明の効果） 本発明による中空糸束端部接着方法を用いると、遠心シ
ール機を使用しないで中空糸束への接着剤のはい上がり
のほとんどない確実な接着ができる。(Advantages of the Invention) By using the method for adhering ends of hollow fiber bundles according to the present invention, reliable adhesion with almost no rise of the adhesive to the hollow fiber bundles can be performed without using a centrifugal sealing machine.
