Abstract
In a method and apparatus for electrocoating from an electrolyzing coating mixture, the temperature of a dialysis fluid is controlled to control the temperature of the coating mixture by heat exchange with the dialysis fluid while at the same time controlling the pH of the coating mixture by osmosis through a dialysis membrane. The flushing chamber and the electrode structure are formed by securing, in sealing relation, the membrane along all edges of one planar side of an electrically conductive sheet with all other surfaces of the sheet and structure not covered by the membrane being covered with an electrically non-conductive material. Central unsecured portions of the membrane are supported by spacers from the sheet surface to form a flushing chamber, and inlet and outlet means are provided through the sheet to enable a flow of dialysis fluid through the chamber sufficient to both cool and control the pH of the coating mixture.
