Why the Anodic Electrophoresis Process is important？

Anodic electrophoresis is an important surface treatment process. Why is it important for aluminum processing?

This is because it can help aluminum products to cope with more complex environments:

1. High corrosion resistance needs:

When aluminum profiles need to be used in harsh environments such as humidity and salt spray. Anodic electrophoresis can form a dense oxide or resin film, which significantly improves its corrosion resistance.

For example, aluminum products such as automobiles, ships, and building facades need to be exposed to the outside environment for a long time. Therefore, anodic electrophoresis treatment is needed to enhance their anti-corrosion performance.

2. Anodic electrophoresis can improve the overall aesthetic appearance of the products.

Anodic electrophoresis treatment can give aluminum profiles rich colors and even luster. For aluminum products that need to show high quality appearance. For aluminum products that need to show high quality appearance, such as the shells of home appliances, door and window frames, etc.. Anodic electrophoresis is an indispensable surface treatment process.

Complex and large aluminum products need its help:

1. Aluminum products with complex shapes need it:

Anodic electrophoresis treatment is suitable for aluminum profiles with complex shapes. Such as workpieces with concave and convex surfaces, holes and other structures. Since the paint can evenly cover all corners of the workpiece during the electrophoretic coating process, it can ensure the surface coating quality of complex shaped workpieces.

2. Large-sized aluminum products:

For large size aluminum plate or aluminum extrusion. The anodic electrophoresis treatment can ensure the uniformity of the coating and avoid color difference, leakage and other defects. This is especially important for large aluminum products that need to maintain overall aesthetics.

Anodic electrophoresis can meet the requirements of environmental protection and energy saving:

1. Environmental protection requirements:

It uses water as the dispersing medium and has fewer co-solvents, which can reduce the pollution of air and water quality. In today’s increasingly strict environmental protection requirements, anodic electrophoresis has become a surface treatment process that meets environmental protection standards.

2. Energy-saving demand:

Anodic electrophoresis treatment has a high recovery rate of paint, which can reduce the waste of paint. Meanwhile, energy consumption and production cost can be further reduced by optimizing process parameters and adopting advanced production equipment.

Specific process steps of anodic electrophoresis:

 

 

1. Pre-treatment:

It includes chemical degreasing, mechanical grinding, cleaning and other steps. These steps aim at removing the oil and impurities on the surface of aluminum to provide a clean substrate surface for the adhesion of electrophoretic coating.

2. Electrophoretic coating:

Under the action of electric field, the coating particles are deposited directionally on the surface of aluminum profile. It will form a uniform and dense coating. This process needs to control the parameters such as solids, pH, electrophoresis temperature, conductivity, electrophoresis voltage and electrophoresis time of the bath to ensure the quality of the coating.

3. Post-treatment:

Post-treatment includes steps such as baking and cooling. The baking temperature and time need to be adjusted according to the type of coating and the specific requirements of the workpiece.

To summarize

When aluminum products need to meet the requirements of high corrosion resistance, high aesthetics, complex shapes, environmental protection and energy saving, etc., anodic electrophoresis treatment is usually required.
