What is the treatment before the Security mesh screen product is sprayed?

Security mesh screen is a familiar high-quality anti-theft, anti-mosquito products. So what is the treatment before Security mesh screen's spray?

What a formal manufacturer of Security mesh screen needs to do is to remove the oil stains and rust on the surface of the steel mesh, and form a layer of anti-corrosion on the surface, which can increase the adhesion of the spray coating. . The main process steps are degreasing, descaling, phosphating, and passivation.

What still needs to be done is the electrostatic spraying of the Security mesh screen. Spray the powder coating evenly onto the surface of the Security mesh screen. Special workpieces

 (including locations where electrostatic shielding is easy to occur) should be finished with a high-performance electrostatic sprayer. Process steps: Using the principle of electrostatic adsorption, a layer of powder coating is sprayed evenly on the surface of the Security mesh screen, and the dropped powder is recovered through a recovery system and can be reused after being sieved.

High temperature curing. The powder coating on the surface of the Security mesh screen is heated to a specified temperature and maintained for a corresponding period of time. Achieve, level, and cure to get the surface effect of the workpiece we want. Process steps: Push the sprayed workpiece into the curing oven, heat it to a predetermined temperature (typically 185 degrees), and keep it for the corresponding time (15 minutes); Generally, the workpiece is different, and the heating temperature and the holding time are also different.
