1.Aluminum profile process is not up to standard: aluminum profile is extruded by aluminum rod, after oxidation coating profile.The selection of aluminum rod raw materials and aluminum profile in the production process of cleaning or pressure check processing is improper, aluminum profile oxidation process of uneven coating, will lead to aluminum profile black mold.
Shenghai Aluminum use 6063-T5 aluminum rod, without doping waste, through strict extrusion production process.Ensure the quality of the aluminum profile from the source.
2、Storage management is improper: although the aluminum profile is waterproof and corrosion resistant, but if it is in a wet environment for a long time, direct contact with the uneven ground.It will also lead to aluminum profile wear, oxide film damage, resulting in aluminum mold black.In view of this situation, the aluminum profile can be stored in a dry and ventilated environment, and should avoid direct contact with the ground.
3、Unreasonable cleaning management: aluminium profiles surface after anodic oxidation treatment, generally do not need to clean. If there is dust, you can use a soft cloth to gently wipe it.If a corrosive cleaning reagent is used, it will cause corrosion and oxidation of the surface of the aluminum profile, leading to mold and blacken the surface of the profile.
