Factors affecting powder consumption in aluminum profile spraying

electrostatic powder coating method is the use of high-voltage electric field induction effect, so that the powder coating and the coating are sensing and each other with the opposite charge, so that the charged powder coating adsorbed to the opposite charge of the coating, and then the powder coating after molten smoothing, baking and curing to obtain the coating methoduntreated aluminum alloy extruded profile appearance is single, and in the humid atmosphere is easy to corrode, so aluminum profiles are generally to be surface treatment, and powder spraying is a major trend in the development of aluminum profiles at this stagebecause of the powder coating has the following advantages: (1) the surface color is rich, soft texture; Therefore, powder coatings have developed rapidly since they were applied to aluminum profilesEspecially in the economically developed Yangtze River Delta and Pearl River Delta region, the market share of powder-coated aluminum profiles has exceeded 60%with the implementation of the national energy conservation and emission reduction policy, as well as the increase of the cost control consciousness of aluminum profile enterprises, reducing powder consumption in aluminum profile spraying is an important direction for energy conservation and emission reduction and cost reductionthere are many factors that affect powder consumption in aluminum profile spraying, there are two main aspectsOn the one hand, it is related to the nature of the powder coating itself, on the other hand, it is closely related to the powder coating process, such as the process conditions of spraying, the spacing of workpieces, the state of use of equipment, the level of operation of employees, etc
