Diaphragms for use in the electrolysis of alkali metal chlorides

摘要

A diaphragm for use in the electrolysis of alkali metal chloride solutions in electrolytic diaphragm cells is comprised of a mixture of sand and a polyolefin thermoplastic polymeric binding agent. The diaphragms may include a support material and an additive such as a lubricant. The diaphragms of the present invention have increased stability, a long operational life and are non-polluting.
