Definition

Colored zinc plating is a process where a colored passivation film is formed on the surface of galvanized metals through passivation treatment. This film can significantly enhance the corrosion resistance of the metal surface.

Process principle.

The passivation film of colored zinc plating is usually treated with a passivation solution composed of components such as chromic acid, sulfuric acid, and nitric acid.

The formation principle of the colored passivation film is to use chemical or electrochemical methods to create an extremely thin film on the metal surface. When light waves are reflected on the surface of the metal and the film, different colors will be formed due to the mutual cancellation of light waves.

Features

- Strong corrosion resistance  : The corrosion resistance of the colored passivation film is more than five times higher than that of the ordinary white passivation film. Moreover, when the surface of the passivation film is scratched, hexavalent chromium can "re-passivate" the scratched area, repair the damage and restore the film to its original integrity.

-  Strong decorative effect  : Colored zinc plating can present a variety of colors, such as rainbow colors, black, etc., and has a good decorative effect.

-  Good adhesion  : The coating is firmly bonded to the substrate and is not easy to fall off.

Environmental friendliness

The traditional zinc plating process uses hexavalent chromium, which is somewhat toxic and poses certain hazards to the environment and human health. With the increasing environmental protection requirements, trivalent chromium or chromium-free passivation processes are gradually being adopted now to reduce the impact on the environment.

1. Strong corrosion resistance:

The galvanized layer can effectively prevent steel from rusting and extend the service life of the bracket.

The surface treatment further enhances the corrosion resistance of the bracket.

2. High strength :

Steel, as the base material, has high strength and toughness and can withstand large loads.

3. Good aesthetic appeal:

The black surface treatment makes the bracket have good decorative properties and is suitable for various scenarios.

4.  Strong customization  :

The size, shape and structure of the bracket can be customized according to the customer's requirements.
