UNA PIEZA TUBULAR POLIMERICA POROSA,UN SEPARADOR POLIMERICO POROSO QUE LA COMPRENDE Y UN METODO DE FABRICACION DE DICHO SEPARADOR

摘要

A separator for an electrolytic cell or similar cell is made of a porous polymeric material, preferably porous polytetrafluoroethylene, and comprises a plurality of tubular portions of such material with one or two flange(s) at end(s) thereof for sealing to other such flanges and to the cell. The flanges are so constructed that when being sealed in place they do not strain or tear and do not strain or tear the material of the tubular portions. The separator is especially useful as a replacement for deposited asbestos diaphragms in electrolytic cells for the manufacture of chlorine and caustic.
