Aluminum profile is a non-ferrous metal profile that is extruded by die and oxidized and coated. The aluminum profile is treated by anodizing and other treatments, and there is an oxide film on the surface, which makes the profile have the characteristics of corrosion resistance and corrosion resistance. Recently, some users found that the aluminum profiles turned black during the use of aluminum profiles. Let us popularize the reasons for the blackening of aluminum profiles.
1. The aluminum profile process is not up to standard: the aluminum profile is extruded from an aluminum rod and then oxidized and coated. The selection of raw materials for aluminum rods, improper cleaning or pressure inspection of aluminum profiles in the production process, and uneven coating during the oxidation process of aluminum profiles will all lead to blackening and mildewing of aluminum profiles. We use 6063-T5 aluminum rods, which are not doped with waste, and undergo a strict extrusion production process. Ensure the quality of aluminum profiles from the source.
3. Unreasonable cleaning management: The surface of the aluminum profile is anodized and generally does not need to be cleaned. If there is dust, just wipe it gently with a soft cloth. If a corrosive cleaning agent is used, the surface of the aluminum profile will be corroded and oxidized, resulting in mildew and blackening of the surface of the profile.
