Ion exchange membrane, method for producing ion exchange membrane and ion exchange membrane cell

摘要

The problem of the present invention is to provide an ion exchange membrane capable of reducing the pressure drop in the flow path and reducing the clogging caused by dirt in comparison with the conventional profile film. Further, in addition to the above, an ion exchange film having little deformation and breakage is provided.Solution: an ion exchange film having an uneven shape, having a flat portion near the edge, a convex bent portion and a concave portion due to bending of the ion exchange film itself, and an ion exchange film having a convex portion and a concave portion in the uneven shape of the ion exchange film, respectively.Selection diagram
