After electroplating other metal on the surface of aluminium and aluminium extrusion , it can significantly improve the surface physical or chemical properties, for example, electroplated silver on the surface can improve the electrical conductibility; electroplated copper, nickel or tin on the surface, it's to make aluminium alloy easy to weld; electroplated chromium is to improve wear resistance; In the decorative aspect, actually mostly adopted electroplating chromium. Aluminium and aluminium alloy surface electroplating have long been tried and used in actual production. The factors that oxidizing material existing between aluminium alloy and electroplated layer, the difference thermal expansivity between aluminium alloy and metal plating, pinhole and residual electroplating solution in electroplated layer etc.caused badly coating adhesion. Long time using will flake peeling off immediately after plating, even in the field of surface treatment, aluminium and aluminium a...

1. The principle of electrophoresis technology The electrophoresis is basically the same as the traditional light and transparent electrophoresis. The anode electrophoresis is carried out under the action of direct current.With the action of the electric field, the coated particles with charge are moved to the coated workpiece, which precipitates the electrophoresis coating deposited on the surface of the aluminum profile, forming a layer of film.The difference lies in the different types of coatings and the slightly different devices. The electrophoretic coating includes acrylic resin, melamine resin, pigments, solvents, neutralizing agents, additives and other ingredients. Through the application of thermal fixing in the viaduct layer in the particle, the shape of the micro-concave coating during the process of baking was basically unchanged in the baking process, and the appearance of the film was formed uniformly.The degree of extinction can be adjusted by the ratio of high ...
