Aluminum profile is a kind of non-ferrous metal profile which is extruded by mold and coated by oxidation. Aluminum profiles are treated with anodic oxidation, and there is an oxide film on the surface, which makes the profiles corrosion-resistant. Recently, some users found that aluminum profiles have blackened in the process of using aluminum profiles, Ustar will give you a popularization, what are the reasons for aluminum profiles blackening?
1, the aluminum profile process is not up to standard: aluminum profiles are extruded by aluminum rods and are coated by oxidation. The choice of raw materials of aluminum rods and improper cleaning or pressure inspection of aluminum profiles in the production process, and the uneven coating of aluminum profiles in the oxidation process will lead to black mold of aluminum profiles. We use 6063-T5 aluminum rods, which are not doped with waste, and undergo a strict extrusion production process. Ensure aluminum profile quality from the source.
2, improper storage management: although the aluminum profile is waterproof and corrosion resistant, if it is in a humid environment for a long time, it is in direct contact with the uneven ground. It will also lead to wear and tear of the aluminum profile and damage of the oxide film, resulting in mildew and blackening of the aluminum profile. In this case, aluminum profiles can be stored in a dry and ventilated environment, and direct contact with the ground should be avoided.
3, cleaning management is unreasonable: aluminum profile surface after anodizing treatment, generally do not need to clean. If there is dust, you can wipe it gently with a soft cloth. If a corrosive cleaning agent is used, it will cause corrosion and oxidation on the surface of the aluminum profile, resulting in mildew and blackness on the surface of the profile.
With the development of technology, the improvement of the level of social development, the market demand for aluminum profiles is also increasing, and various manufacturers are springing up like mushrooms, which directly leads to the flooding of various assembly lines on the market, mixed, if you choose a bad cooperative manufacturer, heavy losses do not say that there may be the introduction of inferior quality to bring major safety accidents. Then when purchasing aluminum profiles, high quality aluminum will be your high-quality choice.
