Studies of Ion Exchange Membranes. XXII. Semicontinuous Preparation of Ion Exchange Membranes by the “Paste Method”

Abstract

A method for the preparation of ion exchange membranes called the “paste method” has been developed into a semicontinuous preparation.The roll-coating system being employed, a base membrane 1 m. wide and 50 m. long is prepared continuously; the ion exchange group is then introduced to it.The ion exchange membranes thus prepared have been proved to have excellent electrochemical and mechanical properties as well as an excellent appearance.
