Powder coating is made of powder spraying equipment (electrostatic spray molding machine) to the application of the powder coating the surface of the workpiece.
under the effect of static electricity, the powder will be adsorbed on the surface, form a homogeneous powder coating.
Metal aluminum powder curing after high temperature above 200 ℃ barbecue become a layer of about 60 microns thick solid bright coating. Make the product surface smooth color uniform with strong acid resistance, alkali resistance, impact resistance, wear resistance can withstand long-term strong ultraviolet radiation and acid rain erosion does not appear coating powder, fade, fall off and other phenomena.
Powder sprayed aluminum profiles have a service life of up to 30 years under normal conditions. Its surface coating in 5-10 years to ensure that no fading, no discoloration, no cracking. Its corrosion are better than ordinary aluminum and color various.
