The traditional surface treatment technology of aluminum profile is oxidation, coloring and closing treatment. When the conversion film of this aluminum material is used outdoors for a long time, especially in acid rain or marine environment, it is easy to corrode and has poor durability. Therefore, it started in the 1970s. Everyone tries to use paint coating methods to further build the decoration performance and service life of aluminum profiles. At present, electrophoretic coating, powder coating and fluorocarbon spraying have been successfully used in industrialization. Among many surface treatment technologies, electrophoretic coating is one of the most applicable technologies in the development direction.  Electrophoretic paint   Electrophoretic paint is based on anodic oxidation, and the oxide film is covered with a water-soluble acrylic paint film through the action of electrophoresis. Therefore, the surface film layer of the electrophoretic profile is a composite film of anodized film and water-soluble acrylic paint film. It has better corrosion resistance, weather resistance and wear resistance than anodic oxidation, and the surface of the profile is smoother and more beautiful. The principle was invented at the end of the 1930s, but the technology was developed and obtained industrial application after 1963. Electrophoretic coating is a special coating forming method developed in the past 30 years, which is the most practical for water-based coatings. Significant construction technology has the characteristics of water solubility, non-toxicity, and easy automatic control. Aluminum can be directly electrophoresed after pre-treatment and washing. The electrophoretic coating has high transparency, which not only has high decoration and can highlight the metallic luster of the aluminum profile itself. Therefore, the use of electrophoretic paint has been continuously increased in the construction of aluminum profiles. It has quickly been widely used in industries such as automobiles, building materials, hardware, and home appliances. Electrophoresis profiles are more decorative than spray paint and powder spraying. The electrophoretic surface treatments are in various colors, with extraordinary texture, classic and simple styles. The colors include electrophoretic silver, electrophoretic champagne, frosted silver, etc. Customers can choose different color styles according to their needs , Is a model of high-end and luxurious profiles, and having an electrophoresis production line has even become an important symbol of the comprehensive technical level of aluminum profile factories. ————The article comes from the Internet.
