Powder coating is a coating of solid particles, usually composed of resins, pigments and additives. In the coating process, the powder coating is first sprayed onto the surface of the workpiece. This process is usually done by a spray gun, and the paint particles form a spray mist with the air stream. When the powder coating contacts the surface of the workpiece with a positive charge, the powder particles will be tightly adsorbed on the surface of the workpiece due to the electrostatic attraction, forming a uniform coating.
Next, the coated workpiece is fed into a baking chamber or oven for thermal curing. Under high temperature conditions, the resin particles begin to melt and flow, and cross-link with the surface of the workpiece to form a strong coating. The process of thermal curing can also make the coating surface stronger and more durable, while improving the gloss and chemical resistance of the coating.
The working principle of powder coating is simple and clear, the coating process is free of solvent volatilization, environmental protection and pollution-free; the coating has high weather resistance and decoration, and is suitable for the surface coating of various metal and non-metal workpieces. Therefore, as an efficient and environmentally friendly coating method, powder coatings are widely used in industrial production.
