The powder coating uses powder coating, and the process uses electrostatic spraying. Under the influence of the accelerating wind, the function of the friction lance is to carry a positive charge when the powder particles are sprayed out of the gun body, and contact with the negatively charged profile to generate static electricity. Adsorbed and then cured at elevated temperatures. It becomes the final coating with different effects (different kinds of effects of powder coating); the spraying effect of powder coating is superior to the painting process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also the same effect. under.

Powder coating has the following significant advantages:

1. The process is relatively simple, mainly due to the improvement of the automatic precision of the main equipment in the production process. Micro-computer control can be realized for some major technical parameters, effectively reducing the difficulty of the process operation, and the auxiliary equipment is greatly reduced;

2, high yield rate, under normal circumstances, if the various measures are appropriate, the maximum control of non-conforming products can be controlled;

3. Some physical indexes of the coating film are significantly improved compared with other surface treatment films, such as hardness, wear resistance and acid resistance, which can effectively extend the service life of the aluminum profile;

4. The degree of pollution to water and atmosphere is reduced. The alkali, sulfuric acid and other liquid organic solvents are no longer used, reducing water and air pollution, and effectively improving the competitiveness of aluminum profiles and plastic steel profiles as environmentally friendly products. Reduced some production costs.
