Electrophoretic coating is a fixed voltage method, the equipment is relatively simple, easy to control. The voltage has a great effect on the film. The higher the voltage is, the thicker the electrophoretic film will be. For the parts that are difficult to paint, the coating ability can be improved correspondingly and the construction time can be shortened. But the voltage is too high, will cause the paint film surface rough, after drying easy to produce "orange peel" phenomenon.
Electroplating process
Electroplating processing voltage is too low, electrolytic reaction is slow, the paint film is thin and uniform, and the permeability is poor. The choice of voltage is determined by the type of paint and construction requirements. In general, the voltage is inversely proportional to the solid fraction of paint and paint temperature, and proportional to the spacing between two ji. The surface of steel is 40 ~ 70V, the surface of aluminum and aluminum alloy can be used 60 ~ 100V, galvanized parts are 70 ~ 85V.
Voltage has an impact on electrophoretic processing. Too high or too low voltage is not conducive to the implementation of the whole process of electrophoretic processing, which must be paid attention to.
