What is the Electrostatic Spray


Spray is a surface treatment method that sprays plastic powder on parts. Spray is the electrostatic powder coating that we often say painting, the treatment process is the 1980s since the international adoption of a more common metal surface treatment of decorative technology. The technology compared with ordinary painting surface treatment, the advantages embodied in advanced technology, energy efficient, safe, reliable, beautiful color and so on. Therefore, it is often used in light industry, home improvement. Its working principle is that the plastic powder is charged by the high-voltage electrostatic equipment, the coating is sprayed onto the surface of the workpiece under the action of an electric field, the powder is uniformly adsorbed on the surface of the workpiece to form a powdery coating, and the powdery coating passes through After curing at high temperature, the liquid will solidify and the plastic particles will melt into a layer of dense final protective coating with different effects; firmly adhere to the surface of the workpiece.

Advantage:

No thinner, no pollution to environment, no poison to human body, excellent coating appearance quality, strong adhesion and mechanical strength, short curing time of spraying construction, much higher corrosion resistance and abrasion resistance of the coating, no need of primer, The construction is simple, the technical requirements of the workers is low; the cost is lower than the painting process; some construction occasions have made it clear that the electrostatic spraying process must be used; the phenomenon of common flowing during the electrostatic spraying process will not appear in the electrostatic spraying process.
