In the electroplating industry, the passivation treatment of the workpiece after galvanizing is a key step to improve the corrosion resistance and decoration of the coating. Zinc is an active metal, and the coating is easily oxidized and corroded without treatment, resulting in rapid darkening and white corrosion products on the surface of the coating. In order to overcome this problem, Bigely Technology has introduced a colored zinc passivation solution Zn-105.
Action principle of colored zinc passivation solution Zn-105
Colored zinc passivation solution Zn-105 is formulated with chromate solution, which can form a dense chromate passivation film on the surface of the galvanized layer. This passivation film can not only reduce the chemical activity of zinc, but also improve the corrosion resistance of the coating by 6-8 times. At the same time, the passivation film also gives the coating a good decorative appearance and anti-pollution ability, so that the workpiece still maintains a bright appearance and long-term protective performance in harsh environments.
