Introduction of powder coating spraying process

powder coating

The spraying process is an extremely important factor that affects the final effect. I will introduce some powder coating spraying processes and the advantages of powder coating to help you achieve a certain degree of understanding of the powder coating spraying process.

To complete a perfect engineering design standard, it is not enough to have high-quality products, but also need a perfect construction process to achieve the final effect of the design, which is also suitable for powder coating spray construction. In my country, there are two main powder coating spraying processes used in powder coating spraying construction, one is electrostatic spraying process, and the other is hammer pattern powder coating spraying process.

1. Electrostatic powder coating

spraying process

The electrostatic powder coating spraying process is an advanced coating process in which the powder coating is atomized finely and uniformly under the action of compressed air, uniformly adsorbed on the surface of the metal workpiece by the action of the high-voltage electric field, and cured at high temperature to form a film. It was first successfully developed by France Sames Company in 1962. In 1965, with Britain, France, Germany, the United States, Japan and other countries successively launched a complete set of electrostatic powder spraying equipment, which has been widely used in industrial production.

2. Hammer grain powder coating spraying process

The hammer pattern powder coating spraying process is the specific process: surface pretreatment of the workpiece to be painted - drying - filling and scraping putty - grinding - drying - spraying. Due to its special film-forming and production process, hammer-grain powder coating needs to pay attention to its special operability when painting, and its coating equipment and construction process need to be properly adjusted to conform to the curing and film-forming of hammer-grain powder coating. requirements.
