Description

technical field

[0001] The present application relates to the technical field of electrophoretic equipment, in particular to an acid-alkaline detection equipment for electrophoretic paint and a process thereof. Background technique

[0002] Electrophoresis is one of the effective methods for coating metal workpieces. Electrophoretic coating means that the conductive object to be coated is immersed in a tank filled with electrophoretic paint, and used as an anode or cathode. Corresponding cathode or anode, after the negative and positive poles are energized for a period of time, a special uniform, fine, water-insoluble film layer is deposited on the surface of the coating.

[0003] In related technologies, when coating metal workpieces on the factory assembly line, the main processes are loading, hot water washing, ultrasonic main degreasing, surface adjustment, phosphating, pure water cleaning, passivation, pure water cleaning, electrophoresis, electrophoresis curing, electr...
