The powder coating of aluminum profiles uses powder coating, and the process uses electrostatic spraying. Under the influence of accelerated wind, the powder particles carry positive charges when they are sprayed out of the gun body under the influence of accelerated wind, and contact with negatively charged profiles, Produce electrostatic adsorption, and then undergo high-temperature curing. The absorption strength of the paint is also enhanced, and the aluminum coiled tape prevents the paint film from falling off.

Ni asiko yi, the powder coatings commonly used in three-sided advertisements are weather-resistant polyester powder coatings. Most of the polyester resins used in powder coatings are saturated. Generally, we can divide them into two groups: terminal carboxyl group and terminal hydroxyl group according to their terminal group structure Big class. When the aluminum profile is sprayed with powder and combined with the thermal transfer technology, it has a more fashionable trend, and the powder sprayed profile has more room for development.

The process of powder coating spraying is relatively simple, and the yield is high. Under normal circumstances, if all measures are taken properly, the generation of unqualified products can be controlled to a greater extent; energy consumption is significantly reduced. Ninu ilana, the consumption of water and electricity is quite large. The processing of industrial aluminum profiles is, especially in the oxidation process. The degree of pollution to water and the atmosphere is reduced, the use of caustic soda, sulfuric acid, and other liquid organic solvents is no longer used, reducing water and air pollution, and also effectively improving the competitiveness of aluminum profiles and plastic steel profiles as environmentally friendly products, and correspondingly reducing Some production costs have been reduced; the labor intensity of workers has been significantly reduced. Due to the use of automated assembly line operations, the feeding method of industrial aluminum profiles and the use of fixtures have been significantly simplified, improving production efficiency and reducing labor intensity; the surface quality of wool The required standard is significantly reduced to improve the surface quality of the finished aluminum profile; Some physical indicators of the aluminum profile coating film are significantly improved compared with other surface treatment films, such as hardness, three-sided advertising, wear resistance, acid resistance, which can be effectively extended The service life of industrial aluminum profiles.
