噴塗鋁型材粉末塗料的要點

The powder coating of 鋁型材 uses powder coating, 並且該方法使用靜電噴塗. 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.

現在, 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. 一般來說, 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. 進行中, the consumption of water and electricity is quite large. The processing of industrial aluminum profiles is, 特別是在氧化過程中. 污染水和大氣的程度減小, 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. 由於使用自動化流水線作業的, the feeding method of industrial aluminum profiles and the use of fixtures have been significantly simplified, 提高了生產效率並降低了勞動強度; 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.
