In recent years, foreign also developed a number of new motor shell technology

    In addition to oxidative dyeing, there are a number of other surface treatment processes, such as painting or painting, and so on. Painting technology is to be washed off after the aluminum products, sprayed with amino baking paint, air flat. Spray paint spray is the use of nitro-colored paint, spray the first primer, and then sprayed against the pattern of flowers, and finally sprayed lacquer.

In recent years, foreign also developed a lot of aluminum surface treatment of new technology and new technologies, such as electrolytic coloring, coated PTFE and enamel process, and has been used in industrial production, so that aluminum products are more colorful and adapt to various uses. Some domestic scientific research units and factories have also experimented with these processes, I believe that soon in the domestic market can see a large number of such products.

    With the development of aluminum smelting and processing technology, aluminum products are now widely used in aviation, building materials, vehicles and other departments. In recent decades, the surface treatment technology of aluminum products has developed extremely rapidly. And through frequent domestic and international scientific and technological exchanges, as well as the efforts of scientific research scholars, test and use of some new technology and new technology. In general, China's aluminum surface treatment technology is still in the development of the development period.

    Aluminum material composition, the purity of the oxidation of aluminum oxide film quality has long been known for scientists and technicians. In industrial production, the quality of domestic aluminum products on the surface of a serious impact on the quality of anodized products, this contradiction more and more prominent. Foreign aluminum products are processed by milling, smooth as a mirror, excellent quality after oxidation. And China, aluminum is often not high gloss, bubbles, scratches, rough skin and other phenomena are very serious, after anodized, these flaws are still revealed. So to improve the quality of sheet metal to become the best quality of aluminum products to ensure an important part of oxidation.
