Powder spraying is a coating process that uses an electrostatic spray molding machine to spray powder coating onto the surface of the workpiece.
Under the action of static electricity, the powder coating uniformly adsorbs onto the workpiece, forming a powdery coating. Sau đó, the powdery coating is leveled and solidified through high-temperature baking to form the final protective coating.
The advantages of this process include good mechanical strength, adhesion, chống ăn mòn, and aging resistance. Hơn thế nữa, the cost of powder spraying is usually lower than that of traditional spray painting processes. Powder coatings are mainly composed of special resins, pigments, fillers, curing agents, and other additives, which are mixed in a certain proportion and prepared through processes such as hot extrusion and crushing and sieving. Its corrosion resistance is better than spray painting, and its surface beauty is highly favored by new and old customers from various countries
