INSTALLATION OF ION EXCHANGE MEMBRANE IN ELECTROLYTIC CELL

摘要

A method of installing an ion-exchange membrane comprising an organic polymer containing ion exchange groups or derivatives convertible to ion exchange groups in an electrolytic cell, comprises expanding the membrane by stretching in order to increase the surface area per unit weight of the membrane, and securing the expanded membrane to the electrolytic cell or part of this. The membranes are useful in electrolytic cells of the type used for the electrolysis of alkali metal chloride solutions. To give chlorine and alkali metal hydroxide.
