What is the main function of aluminum passivator?

Aluminum is a relatively active metal, therefore, it spontaneously forms a very thin oxide film in the air, and in the atmosphere, it has high corrosion resistance. Because the thickness of the oxide film is relatively thin, the thickness is only about 4 nanometers, and the oxide film has a loose structure, porous, low hardness, poor wear resistance and low mechanical strength. Therefore, in order to achieve the purpose of protection, it is necessary to passivate the aluminum parts and generate a passivation film on its surface to improve the corrosion resistance of the aluminum alloy, so the aluminum passivation agent was born.

Aluminum passivation agent is specially designed for aluminum and aluminum alloy passivation treatment, the passivation film produced after aluminum alloy treatment has good stability and corrosion resistance, which greatly improves the corrosion resistance of aluminum alloy materials. In the bare membrane neutral salt spray experiment, the time is longer. The film has strong adhesion to paint, and can be used as a good substrate for post-processing such as painting.

Aluminium passivators can be applied to all aluminium and aluminium alloy surfaces for oxidation and corrosion resistance. Extensive testing has shown that the oxidation resistance of the passivated aluminum and its alloy surfaces is increased by more than 5 to 10 times. Aluminum alloy passivation treatment will not change the appearance color and size of aluminum and aluminum alloy, and will not affect the post-treatment and performance. The aluminum alloy passivation process is also very simple to operate, and everyone can master it.

In the processing process, as long as the oil stain on the surface of the aluminum is cleaned, the residual liquid of the aluminum alloy degreaser is cleaned, it is directly impregnated in the aluminum passivator, let it stand for a few minutes, take it out, wash it with water, and the overall process of aluminum alloy passivation treatment is completed.
