Abstract
1533429 Diaphragms for chor-alkali cells BASF WYANDOTTE CORP 9 Feb 1976 [10 Feb 1975] 04888/76 Heading C7B A diaphragm for a chlor-alkali electrolytic cell is formed from a body of fibres cemented together by a heat-fusible hydrophobic material, e.g. a fluoro hydrocarbon, incorporating sufficient wetting agent to render it hydrophillic; the wetting agent is a perfluorinated organic material or an inorganic material other than asbestos e.g. mica, titinates, talc, vermiculite, titanium dioxide, boron nitride, kaolinite, diatomaceous earth. The diaphragm may be made by depositing a fibrous (e.g. asbestos, thermoset or thermoplastic) slurry on a screen associated with a cathode.
