You certainly don't know why Security screen mesh is electrostatically sprayed?

The market of Security screen mesh is very popular now. Everyone has thought that Security screen mesh is so popular because of its own advantages. It is electrostatically sprayed during the production process. Why does electrostatic spraying work well?

Security screen mesh static spraying

When the powder is sprayed, the powder is adsorbed on the Security screen mesh by corona discharge. The working principle is that the electrostatic powder is sent into the spray gun by the air supply system through the high pressure generated by the compressed air and the high-voltage electrostatic generator at the front end of the spray gun. Due to the corona discharge, a dense charge is generated in the vicinity of it. When the powder is ejected from the muzzle, charged coating particles are formed.

As the powder on the spray increases, the charge builds up more. When a certaint

hickness is reached, the adsorption cannot be continued due to the electrostatic repulsion, so that the entire workpiece is wrapped in a certain thickness. The powder is then heated to melt, smooth, and solidify, i.e., form a hard coating on the surface of the gold rigid web.

The quality of Security screen mesh has a direct relationship with electrostatic spraying, because it is sprayed to ensure that the diamond mesh does not rust and extend the life.

Regular manufacturers will have this step in manufacturing, otherwise it will not be called Security screen mesh。
