[China Aluminum Industry Network] Reasons: Aluminum parts are large, and take a stepped oxidation treatment. Solution: The overall treatment is carried out by taking a piece of plastic cloth and laying it on the ground. According to the outer edge size of the oxidation part, a pool of wood or brick is used to form a pool. The height of the pool can be around, and general flat pieces can be used here. Direct operation in the pool, in case of three-dimensional shape parts, if the height of the pool is not enough, can also be taken in the pool surface treatment, that is, before and after, up and down, left and right in the solution in order to do so can get the same effect with the oxidation in the large tank .
