VERFAHREN ZUR HERSTELLUNG EINES KATIONENPERMEABLEN MEMBRANE MIT EINGEBETTETEM VERSTAERKUNGSGEWEBE UND DIE DABEI ERHALTENE MEMBRANE

摘要

A cation permeable membrane containing areas of thin wall construction comprises a cation exchange polymer matrix having a reinforcement fabric embedded therein. A two-step lamination procedure is described where holes are formed in a film of laminated polymer prior to a second lamination step. The cation permeable membrane has utility in membrane ion exchange, reverse osmosis devices or in electrolytic cells such as chlor-alkali cells.
