Electrostatic powder coating spray principle of the dry powder was adsorbed on aluminum metal spraying scene after a high temperature above 200 ℃ barbecue powder cures to a layer about 60 microns thick solid shiny coating. The product surface is smooth, uniform color with a strong acid and alkali resistance, crashworthiness, abrasion can long withstand intense ultraviolet radiation and acid rain erosion coating does not appear chalking, fading, fall off and so on. Aluminum powder coating service life under normal conditions up to 30 years. Its surface coating in 5-10 years to ensure that does not fade, no color, no cracking. Its weather resistance and corrosion resistance are better than ordinary aluminum and color diversity. The molecular structure of the dielectric can be divided into non-polar molecules and polar molecules of two. Polar molecule consisting of dielectric when subjected to an external electric field paint spray processing, showing electrical; dielectric non-polar molecules composed out well. Atomized spray paint spray nozzle after processing factories, atomized paint particles through a needle or spray gun pole plate, cup edge spray when charged by contact, when the gas ionization region corona discharge generated when , will once again increase the surface charge density. Under these electrostatic field negatively charged paint particles, the polarity of the workpiece surface motion guide, and is deposited to form a uniform coating film on the surface of the workpiece. Conductive paint spray processing, spray processing, spraying sand hung hardware appliances provided by the Dongguan City, Sha Hong Hardware Appliance Co., Ltd.. Dongguan City, Sha Hong Hardware Appliance Co., Ltd. (www.dgshahong.com) strong, credible, in Dongguan, Guangdong spraying equipment industry has accumulated a large number of loyal customers.
