JL Aluminum alloy profile oxidation spray painting customization aluminum extrusion profile

Powder spraying uses powder coating, the process of electrostatic spraying, the use of friction gun, under the influence of the accelerating wind, so that the powder particles sprayed out of the gun body carries a positive charge, and negatively charged profiles in contact with the electrostatic adsorption, and then cured by high temperature. It also enhances the adsorption strength of the paint and prevents the paint film from peeling off.

It has the following advantages:

1、High rate of finished products, in general, if the measures are appropriate, it can reduce the generation of non-conforming products;

2, the degree of pollution to water, the atmosphere is reduced, caustic soda, sulfuric acid and other liquid organic solvents are no longer used to reduce water and atmospheric pollution.

3, the surface quality of the raw material required standards have been significantly reduced, powder coating and can cover the profile surface of the extrusion pattern, cover part of the aluminium profile surface imperfections, improve the surface quality of the finished aluminium profiles;

4, some physical indicators of the coating film than other surface treatment film has significantly improved, such as hardness, wear resistance, can effectively extend the service life of aluminium.
