| abstract | PURPOSE: To provide a filter excellent in the filtering of foreign matter and suppressed in the generation of a gel by coating the surface of a sintered filter material with a chromium oxide film formed by liquid phase reaction. n CONSTITUTION: The surface of a sintered filter material is coated with a chromium oxide film formed by liquid phase reaction. The chromium oxide film may be heat-treated after liquid phase reaction. Further, in the same way as the surface of the sintered filter material, the surface of a perforated support plate or that of a filtrate discharge auxiliary material is pref. coated with a chromium oxide film. It is necessary to form the chromium oxide film by a liquid phase reaction method. For example, a filter is dipped for 1-30min in a solution prepared by adding lead oxide and ferric hydroxide to an aqueous solution with pH of about 12 containing 13-15% of caustic soda and several % of a sodium salt of sulfuric acid, nitric acid or phosphoric acid as an oxidizing catalyst and heated to 104-106°C. By this method, the thermal deterioration of a polymer can be suppressed. n COPYRIGHT: (C)1992,JPO&Japio |
