What is the electrophoresis treatment process for the surface of industrial aluminum?

Everyone should be familiar with the traditional surface treatment process of industrial aluminum. After the surface treatment is anodized, colored and sealed, the aluminum has an oxide film protective layer, which can be used outdoors for a long time, especially in acid rain. In the harsh external environment, it can particularly highlight its advantages. Up to now, the surface treatment technology of industrial aluminum materials has been anodic oxidation, electrophoretic coating and powder coating. Electrophoretic coatings are water-based coatings. materials can be directly electrophoresed after pre-treatment and washing. The electrophoretic coating has high transparency. It is highly decorative and can highlight the metallic luster of the aluminum profile itself. electrophoresis coating is easy to realize automated production. Electrophoresis coating is carried out in a water-based electrophoresis tank, which is more suitable for mass surface coating treatment, and the processing time is short, and it is easier to realize the flow of the entire process. In addition, it is water-based The coating and the coating film are uniform and dense, with high throwing power, and the film thickness can also be controlled by adjusting the electric quantity. electrophoresis coating is extremely safe and environmentally friendly. Electrophoretic coatings are water-diluted, low in solids, and low in solvent content. They are environmentally friendly coatings. They avoid the danger of fire and protect the health of workers. Electrophoresis workpieces can be washed with water, and the utilization of the recovery device makes the paint utilization rate of electrophoretic coating up to 95%.
