    aluminum profile powder coating is a powder coating, the process is used static spray, the use of friction gun role, under the influence of accelerated wind, so that powder particles sprayed out of the gun body carrying a positive charge, with negative charge of the profile contact, produce static adsorption, and then after high temperature curingIt also enhances the adsorption strength of the coating, and the aluminum tape prevents the paint film from falling offthe powder coating currently used in three-sided flip ads for weather-resistant polyester powder coatings, powder coatings used polyester resin sin most of the saturated type, usually we according to the structure of its end base can be divided into end-based and end-hydroxyl two categoriesWhen aluminum profiles are sprayed with powder and then combined with thermal transfer technology, making it more fashionable, so that powder spray profiles have a greater space for developmentpowder coating coating process is relatively simple, high finish rate, in general, if the measures are appropriate, can maximize the control of the production of non-conforming products; Its pollution to water, atmosphere is reduced, alkali, sulfuric acid and other liquid organic solvents no longer used, reduce water and air pollution, but also effectively improve the competitive strength of aluminum profiles and plastic steel profiles as environmentally friendly products, correspondingly reducing some production costs; Significant simplification, improve production efficiency, but also reduce labor intensity, the surface quality requirements of wool material standards significantly reduced, improve the surface quality of aluminum profile finished products, aluminum profile coating film some physical indicators than other surface treatment film has significantly improved, such as hardness, three-sided flipping advertising, wear resistance, acid resistance, can effectively extend the life of industrial aluminum profile
