摘要： Asbestos-free diaphragms for chlor-alkali electrolytic cells are prepared by establishing a liquid permeable diaphragm base mat of fibrous synthetic polymeric material on the cathode structure, providing a coating of inorganic particulate material on the base mat, and treating the coated base mat with a nonionic or anionic surfactant. Preferably, the base mat is coated with the inorganic particulate material using a slurry of the inorganic particulate material suspended in an alkali metal halide brine solution containing the surfactant.
