Powder coating is a kind of coating. Is powder coating harmful to the human body? Let Pipeline Anti-Corrosion Powder Coatings Manufacturer explain it to everyone today.
Powder coating is harmless to the human body, because powder coating is non-toxic, does not contain solvents, does not contain volatile and toxic substances, has no poisoning, no fire, and no "three wastes" emissions, which fully meets the requirements of national environmental protection laws.
Its harm is mainly to the workers who produce it, because the curing agent used in it is likely to cause allergies and cause poisoning, but it has reacted after spraying and only releases a small amount of water vapor. This is no longer harmful. During the production process, crushing, powder mixing, pigment dispersion and other processes will generate a large amount of dust, so protective measures need to be taken. Therefore, for daily use, powder coatings are not harmful to the human body.

What methods are available for Powder Coatings?
To complete a perfect engineering planning standard, high-quality products are not enough. It also requires perfect construction technology to achieve the final result of the plan. This principle is also suitable for powder coating spraying construction. In China, there are two main types of powder coating spraying processes used in powder coating construction, one is electrostatic spraying, and the other is hammer-grained powder coating spraying.
1. Electrostatic powder coating spraying process
The electrostatic powder coating spraying process is an advanced coating process that atomizes the powder coating finely and uniformly under the effect of compressed air, and evenly adsorbs on the appearance of metal workpieces by means of the effect of a high-voltage electric field. The French company Sames first developed it in 1962. In 1965, along with Britain, France, Germany, the United States, Japan and other countries successively introduced complete sets of electrostatic powder spraying equipment, it has reached widespread use in industrial production.
2. Hammer grain powder coating spraying process
The hammering powder coating spraying process is a specific process: the surface pretreatment of the workpiece to be painted-drying-filling putty-sanding-drying-spraying. Because of its special film formation and production process, the hammered powder coating needs to pay attention to its special operability when painting, and it needs to properly adjust its coating equipment and construction process, which is consistent with the curing of the hammered powder coating film. Requirements.
