Introduction of common technology for surface treatment of aluminum

Update time : 2022-08-26 11:54:12

In recent years, the application of aluminum alloy profiles in our lives has become more and more common. The subsequent processing of aluminum profiles is indispensable for the development of the surface treatment process. If the surface treatment process cannot be carried out smoothly, it will affect the quality of the aluminum profiles. What are the surface treatment processes that are often used for aluminum profiles? Let's introduce the three most widely used surface treatment processes.

1. Electrophoretic coating: On the basis of anodic oxidation, through the action of electrophoresis, a layer of water-soluble acrylic paint film is evenly covered on the oxide film, so that the surface of the profile forms a composite film of anodized film and acrylic paint film. The hand feels smooth and delicate, and the appearance is bright and bright. In addition to the original oxidation coloring color, it can also make more bright colors such as white and green.

2. Color powder coating: a total of more than 200 color options, stable performance, strong paint film adhesion, not easy to peel off, acid resistance, salt spray resistance, weather resistance, aging resistance and other properties. The coating is non-volatile, non-oxidizing and toxic in the air, and has good environmental protection performance.

3. Color fluorocarbon spraying: spray the polyvinylidene fluoride paint coating on the surface of the aluminum alloy substrate by electrostatic action. Fluorocarbon coatings are polyvinylidene fluoride and fluorocarbon coatings. Therefore, it can have the advantages of long-lasting color retention, corrosion resistance, and air pollution resistance. Its fluorocarbon bond is one of the strong molecular bonds in its polymerized molecular structure. As a surface treatment method, fluorocarbon spraying has the advantages of uniform color and resistance to fading and contamination.
