Powder spraying is to spray powder coating on the surface of workpiece with powder spraying equipment (electrostatic plastic spraying machine). Under the action of static electricity, the powder will be uniformly adsorbed on the surface of the workpiece to form a powdery coating. Powder coatings are baked, leveled and cured at high temperature to become final coatings with different effects (different kinds of effects of powder coatings).
Fluorocarbon spraying is a kind of electrostatic spraying and liquid spraying, which is called fluorocarbon spraying, and it is called curium oil in Hong Kong. It belongs to high-grade spraying, so the price is higher.
2. Differences in characteristics
The spraying effect of powder spraying is superior to the coating process in mechanical strength, adhesion, corrosion resistance and aging resistance, and the cost is lower than that of the same effect.
Fluorocarbon spraying has excellent fading resistance, freezing resistance and corrosion resistance to air pollution (acid rain, etc.). ), strong anti-ultraviolet ability, strong anti-cracking ability, and can withstand harsh weather environment. It is beyond the reach of ordinary coatings. The fluorocarbon coatings with excellent quality have metallic luster, bright color and obvious three-dimensional effect.
3. Differences in structural composition
Electrostatic powder spraying system is mainly composed of powder supply device, one or more sets of electrostatic spray gun and control device, electrostatic generator and powder recovery device. In the powder supply device, the powder is in a fluidized state, which is realized by the action of compressed air, and then the powder is carried by the high-speed airflow through siphon action, forming powder-gas mixing, and finally reaching the spray gun.
Fluorocarbon paint spraying is a kind of paint baked with polyvinylidene fluoride resin n(ch2cf 2)n(ch2cf 2)n(PVDF) or mixed with aluminum powder as pigment. Fluorocarbon spraying equipment adopts imported computer software and different models of electrostatic spray gun. High-voltage electrostatic spray gun is mostly used, and fluorocarbon spraying process is mostly multi-layer spraying.
