Abstract
1383365 Treatment of electrolyte P P G INDUSTRIES Inc 10 March 1972 [11 March 1971] 11201/72 Heading C7B A method of controlling the contents of an electro-deposition bath containing a film-forming vehicle resin in an aqueous medium comprises subjecting at least a portion of the bath to electrodialysis and another selective separation process which passes an aqueous effluent through a physical barrier whilst retaining the vehicle resin component. The vehicle resin may be a polycarboxylic acid resin solubilized with potassium hydroxide or may be a polybasic resin solubilized with an acid the electrodialysis membrane may be interposed between the electrodes during the electrodeposition process. It may be a cloth of plant fibres or a cation exchange membrane having a pore size less than 20. The selective separation process may be ultra-filtration or reverse osmosis. The ultra-filter may comprise 0À1-10 micron thick layer of a homogeneous polymer supported on a layer of a micro-porous open celled sponge that may be 20 microns-1 millimetre thick. The sponge may be further supported on a sheet of paper. The membrane polymer may be polyvinyl chloride, polyacrylonitrile, polysulphones, poly (methyl methacrylate), polycarbonates, poly (n-butyl methacrylate). Electro-deposition tank 1 has an electrode compartment 3 having an input line 9 and an output line 11. The electrode 33 to be coated is suspended from a grounded conveyer 37 and current is supplied via bus-bar 27 through hanger 31. Electrolyte is intermittently circulated through separator 13 having an ultra-filter. Effluent is discharged through outlet 19.
