Many people may find aluminum coil corrosion, what caused corrosion and how to avoid corrosion? Come fornitore professionale di bobine di alluminio, HuaWei aluminum give you the answer! Normal oxidation refers to the aluminum coil after use, such as after wrapped in the pipeline, the aluminum coil surface will be completely contact to the air and form a layer of oxide film, this layer of oxide film will protect the aluminum coil, so after use, even if the rain and outdoor exposure, aluminum coil will not be corroded any more. Corrosive oxidation refers to the aluminum coil before being used, because the packaging roll state, aluminum coil surface is not completely contact with air, it has not yet formed a protective layer, in questo caso, if the aluminum coil contact with water, such as rain or damp, the moisture and aluminum coil surface will have chemical reaction, resulting in aluminum coil corrosion, aluminum coil will appear corrosion marks, severe situation will be black, like burned by fire. But this kind of corrosion occurs, there will be no secondary damage to the aluminum coil, aluminum coil itself has no problem, but the appearance of damage.
