Requirements for anodizing process operation of aluminum profiles

Update time : 2022-10-09 19:31:27

With the vigorous development of the aluminum processing industry, aluminum surface treatment has become an indispensable and important production link in the aluminum processing process. Because other buildings that constitute the decoration, such as aluminum products, arts and crafts, decorations, furniture, etc. are beautiful and generous, and meet the requirements of the aesthetics of the times, the application value of aluminum profiles is very high.

In order to decorate and improve the surface properties of aluminum materials, coloring treatment is carried out on the oxide film of aluminum materials. Commonly used methods include electrolytic coloring method, chemical coloring method, natural coloring method, etc.

In actual production, due to differences in personnel, process, equipment, operation, etc., the color difference of each batch of products will also have a certain difference, resulting in different quality defects. Under a specific medium, the depth of the color is determined by the deposition of metal particles. determined regardless of the thickness of the oxide film. The generation of color difference in electrolytic coloring of aluminum materials is directly related to the coloring mechanism, the uniformity and structure of the thickness of the oxide film, and the speed of electrolytic coloring.

The defects of aluminum coloring are generally in the following situations: light color, color difference, dyeing, white spots, dew white, dyeing and blooming, color escape, etc. How to solve this problem to ensure that the color difference of each batch of products is consistent and within the deviation range confirmed by both parties to meet the requirements of consumers. This requires manufacturers to study and prevent the electrolytic coloring surface treatment of profiles.
