Talking about the surface spraying treatment of industrial aluminum profiles

The powder coating technology of industrial aluminum profiles has good anti-corrosion function and decorative function. It is widely used in the industrial aluminum profile industry and the aluminum profile industry. It is one of the most effective coatings, and the fastest in various coating types. . However, aluminum alloy profiles have also found technical defects in coatings and coatings as an improved basis.

1. The requirements for manufacturing powder coating equipment are higher, and the solvent type or water-based coating equipment is more refined, and the system is also higher.

2. Due to the complexity and precision of the equipment, the system is also high.

3. Due to the complexity and fineness of the equipment, the powder coating is not suitable for a variety of types, and the multi-patterns are used in different turns, and it is difficult to change the type and change the color.

4. Coating equipment for powder coatings requires the installation of powder coatings. It is not as complicated as the construction of solvent-based coatings. At the same time, it is necessary to think about avoiding dust explosions and other equipment investment.

5. The hardening point of the resin for powder coating is generally above 85 °C. In the process of manufacturing powder coating, the melt extrusion temperature is 10 °C higher than the hardening point, and the melt leveling temperature at the time of coating is at most higher than the hardening point 30-40. Above °C, the baking temperature of the powder coating is less than 150 °C, and the baking temperature is high. It is not suitable for the coating of plastics, wood, paper and other substrates with poor heat resistance, and is not suitable for soldering parts, electronic components, etc. Painting of heat-resistant articles.

6. Due to the coating equipment and baking temperature and other achievements, the original Jiangyin aluminum profile manufacturer's coating or waterborne coating equipment or coating line can not be indirectly coated with powder coating.
