The cathode electrophoresis is a coating process generally adopted in the manufacture of automobile bodies, and is a main means for prolonging the service life (corrosion resistance) of the automobile bodies. The electrodeposition paint used in the cathodic electrodeposition is a cationic (positively charged) resin and a pigment, and the object to be coated (vehicle body) serves as a cathode.
In the process of cathode electrophoretic coating, when resin cations with positive charges are deposited on a workpiece, organic acid radical ions (acetate ions and formate ions which are derived from electrophoretic paint) are continuously generated in the bath solution and are correspondingly accumulated in the bath solution. When too much organic acid radical ion accumulates in the bath solution, it directly results in a decrease in the pH of the bath solution and an increase in conductivity. In order to ensure optimum coating results and stable paint liquids, these acid ions must be removed continuously during the coating process by means of an anodic circulation system. In the prior art, the anolyte is generally subjected to a renewal cycle to continuously remove the acid radical ions, and a large amount of pure water is required for dilution during the process, so that the water consumption is high, and the dilution efficiency is low.
