Advantages of electrophoretic coating of aluminum profiles

[China Aluminum Industry Network] 1. Easy to achieve automated production. Since the electrophoretic coating of aluminum profiles is performed in an aqueous electrophoresis bath, similar to the anodizing and electrolytic coloring processes, the processing time is short, and it is easy to realize the assembly line operation of the entire process.

2. The film is uniform and dense. Due to the high throwing power of the electrophoretic coating of aluminum profiles, it is possible to obtain a uniform coating film for the shape of the complex shape and to control the film thickness by adjusting the amount of electricity.

3. The utilization rate of paint is high. Due to the low viscosity, the workpieces are carried less, and the electrophoresis workpieces can be washed with water. The utilization of the recovery device enables the electrophoretic coating to have a utilization rate of more than 95%.

4. Security and environmental protection. Because the electrophoretic coating is diluted with water, the solid content is low, and the solvent content is low, it is an environment-friendly paint, and the risk of fire is eliminated, and the health of the workers is also guaranteed.

5. The coating quality is good. Acrylic resin is cured with amino resin to ensure the high decoration and high corrosion resistance of the coating film. At the same time, because the resin is highly transparent, it effectively highlights the metal texture of the aluminum profile, and can be decorated with matt, sand, pearl, etc. as required. effect.

6. Compared with the conventional electrolytic coloring and sealing process, it has the advantages of time saving and labor saving. The electrophoretic coating film does not need to be sealed, and cracks and other defects caused by bad sealing holes are avoided.

7. The thickness of the coating film can be freely controlled, and both the 7μm and 12μm are normally controlled at home and abroad.

8. Because the electrophoretic layer is transparent and bright, aluminum ingots are required to have high quality, smooth surfaces of the extruded materials, and fewer mechanical defects. The oxidative coloring process requires strict management, because any minor defects and stains will be exposed under transparent paint.

9. High requirements for electrophoresis process management to increase the yield of aluminum profiles.
