Abstract
1336225 Chlor-alkali cell NIPPON SODA CO Ltd 8 July 1971 [9 July 1970] 32175/71 Heading C7B A chlor-alkali cell comprises corrosion resistant metal electrodes and a diaphragm comprising a layer of corrosion resistant and electroinsulating fibres and at least one net on the cathode side of the fibres. There may also be a net on the anode side. The fibres may be asbestos, glass, polyurethane, polyvinylidene chloride, polypropylene, polyfluoro ethylene or carbon fibres. The net may be polyvinylidene chloride, polypropylene, polyfluoroethylene or polyurethane or a metal such as stainless steel, titanium or iron or iron coated by either titanium or platinum. The net may be 10-32 mesh and the fibre layer 1-10 mm thick. The electrodes may be perforate or unperforate plates of wire nets. They are made of iron, titanium, platinum, platinum / rhodium, or ruthenium/iridium. The cell in Fig.3 has plate anodes 2, wire net cathodes 1, diaphragms 3 and nets 4.
