The plasma process in the metal industry is not only absolutely environmentally friendly, but also improves efficiency and economy

The coating of metal coils requires pre-treatment to remove oil stains on the surface, so that the coating material has a reliable adhesion to the coils. Traditional processes often use multiple complex and expensive chemical treatments. Plasma processes are not only absolutely environmentally friendly, but also improve efficiency and economy. In particular, the application of aluminum or aluminum alloys has become more widely used, and the output of sprayed aluminum has reached almost half of the total amount of aluminum. However, aluminum and aluminum alloys will form a loose natural oxide film in the natural environment. Before the chromization treatment, the aluminum must be fully degreased and degreasing, and the natural oxide film must be removed at the same time, and then the chromization treatment can be carried out. , A chemical oxide film with a thickness of 0.5-1.0um is formed. The main purpose of the chromization treatment is to form a film with many small corrosion holes on the surface of the aluminum alloy, so that the powder spray material can penetrate into the micropores. After baking, leveling, and curing, these spray materials will be firmly embedded in the oxidation In the micropores of the layer, it is difficult to separate the coating from the substrate, so as to realize the long-term protection of the aluminum material by the spraying material.

The oil and oxides of the weld bead must be thoroughly removed before the aluminum-iron plate is welded, which not only enhances the welding strength, suppresses voids, and greatly improves the corrosion resistance of the weld bead and better appearance quality.
