How is Security Screen Painted

MAISHI is a professional security screen mesh manufacturer in China, and we are proud to have the top quality in China. For powder coating, we use the world top brand powder -- Akzo Nobel powder, which could keep the original bright and shiny color even after years of usage.

For security screen mesh, we use electrostatic coating. The powder coating is fed into the spray gun by the powder supply system by compressed air gas. The high pressure generated by the high-voltage electrostatic generator is added to the front end of the spray gun. Due to the corona discharge, a dense charge is generated near the spray gun, and the powder is charged when the powder is ejected from the nozzle. The paint particles, which are absorbed by the electrostatic force, are attracted to the security mesh screen with the opposite polarity. As the powder sprayed increases, the charge builds up. When a certain thickness is reached, it does not continue due to the electrostatic repulsion. Adsorption, so that the entire mesh screen obtains a certain thickness of the powder coating, and then heated to melt, level, and solidify the powder, that is, form a hard coating film on the surface of the mesh screen.
