    摘要: A non-asbestos, electrolyte permeable diaphragm fabricated of thermoplastic organic polymer material containing ion exchange functional groups or precursor groups thereof is disclosed. The diaphragm can be prepared by providing a slurry of the organic polymer material, depositing the organic polymer material upon a cathode substrate and treating the organic polymer material to secure a stable diaphragm.

    摘要: A polymeric metal oxide such as polytitanic acid, polyzirconic acid or polysilicic acid is incorporated into a liquid permeable diaphragm formed of, e.g., asbestos, asbestos and a polymer resin, polytetrafluoroethylene, or a major amount polyfluorocarbon fibrils and a minor amount perfluorinated ion exchange material. Optionally, the diaphragm may also include inorganic materials such as zirconium oxide, titanium dioxide, aluminum oxide, talc, barium sulfate or potassium titanate, and hydrous inorganic gels such as magnesium oxide gel, zirconium oxide gel, titanium oxide gel or zirconyl phosphate gel.
