Industrial aluminum coil oxidation technology and sealing technology are relatively common in the surface treatment of aluminum processing. The sealing and oxidation process design of industrial aluminum companies can continuously enhance their appearance corrosion resistance. Industrial aluminum in many countries At the time of sampling, most of our work comes out through inspection results because the sealing is not qualified or the oxide film is not qualified.
When industrial alumina, you need to pay special attention to the temperature. Excessive temperature may increase the production of oxide film pores, expand the orifice, reduce the weight of the pore, and loosen the film, so that the corrosion-resistant aluminum industry processed poorly; if the temperature is too high It is low, the pore size becomes smaller, the dense film, and the sealing performance is good, but the color of the film is poor, and the production greatly increases the cost, which makes us need to control the oxidation temperature well.
Industrial aluminum materials should be sealed effectively in time after oxidation and coloring, and should not be stored in water for too long. Because industrial aluminum materials in China need to be placed in water for a long time, the chemical reaction activity and adsorption capacity of the oxide film can be If the fluoride ions cannot be fully absorbed into the membrane pores during sealing, it will directly lead to incomplete sealing.
From the above, the key to industrial aluminum processing lies in the structure of the oxide film and the quality of the sealing hole.
