【発明の詳細な説明】
産業上の利用分野
本発明は透析装置、純水製造装置あるいは燃料電池など
のイオン交換膜のシール方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method of sealing an ion exchange membrane in a dialysis device, a pure water production device, a fuel cell, or the like.
従来の技術
従来イオン交換膜のシール方法は、ガスケットを介して
押圧する方法が一般的であった。BACKGROUND TECHNOLOGY The conventional method for sealing ion exchange membranes has been to press the membrane through a gasket.
発明が解決しようとする問題点
しかしながら、ガスケットによるシール方法は、押圧力
か一定の範囲内でなければシール効果が無い場合が多（
、ヒートサイクルによる部材の膨張収縮や押圧装置の疲
労などにより液洩れが生じ易く、また多数のセルを積層
して用いる場合などは各セル間で押圧力のバラツキが生
じ易くシール不良が発生することか多かった。Problems to be Solved by the Invention However, sealing methods using gaskets often have no sealing effect unless the pressing force is within a certain range (
Liquid leakage is likely to occur due to expansion and contraction of members due to heat cycles and fatigue of the pressing device, and when many cells are used in a stacked manner, variations in pressing force between each cell are likely to occur, resulting in seal failure. There were many.
一方、イオン交換膜の多くは湿潤状態で取り扱かわれる

多い。しかし、上述のようなガスケットシールでは、押
圧力の不均一が生じることを避けるため、充分に時間を
かけて締付・押圧することが多く、その間にイオン交換
膜が乾燥して機能か損なわれることがあった。On the other hand, most ion-exchange membranes are handled in a wet state, and once they dry out, their functionality is often impaired. However, with the gasket seals mentioned above, in order to avoid uneven pressing force, it is often necessary to tighten and press the seal for a sufficient amount of time, during which time the ion exchange membrane dries and loses its functionality. Something happened.
問題を解決するための手段

ある。Means for Solving the Problems In view of the above points, the present invention uses, instead of a gasket, a thermoplastic resin porous body made of closed cells that expands upon heating to become an elastic body. This is an attempt to seal a pressure-build ion exchange membrane through thermal expansion.
作用
イオン交換膜の機能を損うことなく簡単に良好なシール
状態が得られる。A good sealing condition can be easily obtained without impairing the function of the ion exchange membrane.

に長時間を費す必要もない。Furthermore, a second frame 6 having a gap 5 that confines the thermoplastic resin porous body 4 is brought into contact with the second frame 6, and the first frame 2 and the second frame 6 are joined by tightening bolts 7. The whole is heated while immersed in an aqueous solution whose boiling point has been raised by a solute. If the thermoplastic resin porous body 4 is made of polyethylene, for example, the temperature is about 105 to 120"C. By heating, the thermoplastic resin porous body 4 expands and becomes a thermoplastic resin elastic body, filling the gap 5'. A seal is formed between the ion exchange membrane 1' and the second frame C. The first frame 2 and the second frame C have a fluid population 8.8' and a fluid outlet 9.9', respectively.
Either the ion exchange membrane 1' is provided with an ion exchange membrane 1' and acts as a fluid system, or the seal prevents the two fluids from mixing. The first frame body 2 and the second frame body 6 are joined by the tightening bolts 7 by simply keeping the dimension of one gap 5 almost constant against the expansion of the thermoplastic resin porous body 4 due to heat treatment. There is no need to keep the pressing force within a certain range or spend a long time tightening.
