ã€ALUMINIUM NETWORK】Aluminum powder coating adopts powder coating. Electrostatic spraying is used in the process. Using the function of friction spray gun, under the influence of accelerated wind, the powder particles will carry a positive charge when they are sprayed out of the gun body. Contact with negatively charged profiles produces electrostatic adsorption and then cures at high temperatures. It also enhances the strength of the coating, and the aluminum tape prevents the paint film from falling off.
From the point of view of the process itself, it has a very high technological composition and the deployment of different colors of paint, resulting in different colors of the decorative effect, more in line with the needs of interior decoration, but also with the development trend of industrial aluminum profiles in the construction industry to the interior Consistent. In particular, the combined use of spray profiles and thermal break bridges has made them more fashionable, enabling powder sprayed profiles to have more room for development and also being unreplaceable by other processing methods.
The powder coatings currently used in three-sided advertisements are weather-resistant polyester powder coatings. The polyester resins used in powder coatings are mostly saturated. Usually, we can divide the carboxyl-terminated and hydroxyl-terminated hydroxyls according to the structure of their end groups. Big class. When the aluminum profiles are sprayed with powder and then combined with thermal transfer technology, they are more fashionable and make the powder coating profiles have more room for development.
Powder coating spraying process is relatively simple, high yield, under normal circumstances, if all measures are appropriate, can greatly limit the production of non-conforming products; energy consumption is significantly reduced, in the ordinary anodizing, electrophoretic coating production In the process, the consumption of water and electricity is quite large. Industrial aluminum profiles are processed especially in the oxidation process. Its degree of pollution to water and atmosphere is reduced, and caustic soda, sulfuric acid, and other liquid organic solvents are no longer used, reducing water and air pollution, and effectively increasing the competitiveness of aluminum profiles and plastic steel profiles as environmentally friendly products, and correspondingly reducing Some of the production costs; the labor intensity of workers has been significantly reduced, due to the use of automated assembly line operations, the use of industrial aluminum profiles and fixtures have been significantly simplified, to improve production efficiency and reduce labor intensity; the surface quality of the wool The requirements for standards have been significantly reduced to improve the surface quality of aluminum finished products; some physical indicators of aluminum coating films have been significantly improved compared with other surface treatment films, such as hardness, three-faced advertisement, abrasion resistance and acid resistance, which can effectively extend Industrial aluminum life.
