The surface coating (coating) process of aluminum alloy profiles refers to the process of producing cross-linked polymerizations with certain materials through a certain process, thereby forming a coating process with a certain thickness on the working surface. This coating is called Surface coating or surface coating. The main role of the coating is the following three points:

     (1) Protection. In the process of using aluminum alloy profiles, long-term exposure to the air will be eroded by oxygen, moisture, acid, salt spray, corrosive gases, and ultraviolet rays. On the surface of the profile that needs to be protected, a certain thickness of the coating (ie, protective layer) is formed by a certain coating process, thereby providing protection.

     (2) decorative effect. Paints can be formulated in a wide variety of colors, plus the coating is smooth and bright, and even a variety of three-dimensional texture effects, such as hammer lines, orange lines, grain lines, and suede, make the products beautiful and look and The special properties required will play a role in beautifying the human environment.

     (3) Other effects. In addition to the protective and decorative effects of the coating, it also has many special features such as electrical insulation, static conductivity, anti-fouling, heat resistance, wear resistance, heat preservation, reflective, anti-noise, shock absorption, anti-skid, anti-UV and so on. These special features of the coating enhance the use of the product, broaden the scope of application of the product, and make coating products more widely used in the national economy.
