Advantages of electrophoretic coating method for aluminum profiles
Easy to realize automatic production. Because the electrophoretic coating of aluminum profile is carried out in the aqueous electrophoretic tank, which is similar to the anodic oxidation and electrolytic coloring process, and the processing time is short, it is easy to realize the whole process, which is far more than the coating surface assembly line operation. 1. It is easy to realize automatic production. Because the electrophoretic coating of aluminum profile is carried out in the aqueous electrophoretic tank, which is similar to the anodic oxidation and electrolytic coloring process, the processing time is short, and it is easy to realize the assembly line operation of the whole process
2. The coating is uniform and dense. Due to the high penetration of the electrophoretic coating of aluminum profile, the profile with complex shape can also obtain a uniform film, and the film thickness can be controlled by adjusting the electric quantity
3. The utilization rate of coating is high. Due to the low viscosity, the workpiece belt can withstand a pressure of up to 0.25MPa and a high temperature of 260 ℃, and the electrophoretic workpiece can be washed with water. The utilization of the recovery device makes the utilization rate of the electrophoretic coating paint up to more than 95%
4. Safety and environmental protection. Due to the water dilution, low solids and low solvent content of the electrophoretic coating, it is an environmental friendly coating, which avoids the risk of fire and ensures the health of workers
5. Good coating quality. Acrylic resin is cured with amino resin, which ensures the high decoration and high corrosion resistance of the film. At the same time, due to the high transparency of the resin, it effectively highlights the metal texture of aluminum profile. According to the needs, it can also get decorative effects such as matte, sand surface, pearlescent, etc. to improve the added value of products
6. Compared with the usual electrolytic coloring sealing process, it has the characteristics of saving time and manpower. The electrophoretic coating does not need to seal another hole, avoiding the defects such as cracks caused by poor sealing
7. The thickness of the coating film can be freely controlled. At home and abroad, it is usually controlled at 7 m and 12 M
8. Because the electrophoretic layer is transparent and bright, it is required that the aluminum ingot is of high quality, the surface of the extruded material is smooth, and there are few mechanical defects. The management of the oxidation coloring process is strict, because any minor defects and contamination will be exposed under the transparent paint
9. High requirements for electrophoresis process management to improve the yield of aluminum profiles
