Powder spraying uses a powder spraying device (electrostatic spraying machine) to spray powder coating on the surface of the workpiece. Under the action of static electricity, the powder will be evenly adsorbed on the surface of the workpiece to form a powder coating; the powder coating is then dried at high temperature The bake-leveling cures and becomes a coating with different effects (different kinds of effects of powder coatings). The spraying effect of powder spraying is superior to the spraying process in terms of mechanical strength, adhesion, corrosion resistance and aging resistance, and it is more cost-effective than spraying with the same effect.
Advantages of powder coating:
◆ Efficient: One-time film formation can increase productivity by 30-40%.
◆ Energy saving: reduce energy consumption by about 30%.
◆ Less pollution: It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of coating film.
◆ High coating utilization rate: The powder can be reused multiple times after recycling, and the utilization rate is over 95%.
◆ Good film coating performance: the thickness of one-time film formation can reach 50-80um, and the comprehensive indicators such as adhesion and corrosion resistance are better than those of the paint process.
◆ High yield: before re-curing, it can be re-sprayed twice.
◆ Various types: There are many types of powder coating processes. There are two types of electrostatic spraying and plastic dipping.
