Spraying Points of Powder Coating for Aluminum Profile

2021-07-28

Powder coating is used for powder spraying of aluminum profile, and electrostatic spraying is used in the process. Under the influence of accelerating wind, the powder particles carry positive charge when they are sprayed out of the gun body, and contact with the profile with negative charge to produce electrostatic adsorption, and then solidify at high temperature. It can also strengthen the adsorption strength of the coating and prevent the coating film from falling off.

1) The process of powder coating spraying is relatively simple and the rate of waste products is high. Under normal conditions, if the measures are appropriate, the generation of unqualified products can be controlled to the maximum extent; The energy consumption is significantly reduced. In the consumption process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is quite large. Industrial aluminum profile processing, especially in the oxidation process, reduces the pollution level of water and air, and does not use flake alkali, sulfuric acid and other liquid organic solvents to reduce water and air pollution, It also effectively improves the competitive strength of aluminum profiles and environmental protection products of plastic steel profiles, and correspondingly reduces some consumption costs; The labor intensity of the workers decreased obviously;

2) Due to the use of automatic assembly line operation, the feeding mode of industrial aluminum profile and the application mode of fixture have been significantly simplified, which has improved the consumption efficiency and reduced the labor intensity; The appearance quality of the raw material is obviously reduced, and the appearance quality of the aluminum profile scrap is improved

3) Some physical indexes of the powder coating film on aluminum profiles are obviously improved compared with other surface treatment films, such as hardness, wear resistance and acid resistance, which can effectively extend the service life of industrial aluminum profiles.
