〔産業上の利用分野〕
本発明は、陰イオン交換膜に関する。更に詳しくは、含
浸膜タイプの陰イオン交換膜に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to anion exchange membranes. More specifically, it relates to an impregnated membrane type anion exchange membrane.

ものとに分類される。The anion exchange membranes used in diffusion dialysis are impregnated membrane types in which a nonwoven fabric or the like is impregnated with a resin having ion exchange groups, and the other is an impregnated membrane type in which a nonwoven fabric is impregnated with a resin having an ion exchange group on a support. - It is classified as a membrane type coating.
しかるに、含浸膜タイプのものでは、その膜厚が不織布
などの厚さに依存するのであまり薄くすることができず
、また有効膜面積も必然的に小さくならざる全得ない。However, in the case of an impregnated membrane type, the membrane thickness depends on the thickness of the nonwoven fabric, etc., so it cannot be made very thin, and the effective membrane area inevitably becomes small.

の接着性ということが常に問題となる。On the other hand, for composite membrane types, the thickness of the ion-exchange resin layer, which is the active layer, can be made considerably thinner by selecting the manufacturing method. That is always a problem.

浸させることが有効であることを見出した。The present invention aims to improve the insufficient dialysis performance of the impregnated membrane type due to the above-mentioned drawbacks, and various studies have been carried out in search of a solution to the problem targeted by the present invention. As a result, the present inventor found that it is effective to impregnate a specific lipid bilayer membrane.

きる。Polymer and other porous substrates are molded from polytetrafluoroethylene, polyvinylidene polyfluoride, polypropylene, etc., which have excellent acid resistance, and have a pore diameter of approximately 0.01N.
A porous material in the microfilter range of 1 μm is used. Further, a film having a thickness of about 100 μm or less is preferably used, but a nonwoven fabric having a film thickness of about 150 μm can also be used, although it is slightly inferior in terms of acid dialysis rate.

それによって透析性能の向上がみられる。The anion exchange membrane according to the present invention has a porous substrate impregnated with a cationic dialkyl ammonium salt lipid in a bilayer membrane structure, so that the charge density relative to the effective membrane area is lower than that of conventional impregnated membrane types. The dialysis performance is therefore improved.
