Powder coating powder is a kind of building material often used in the modern construction industry. It is generally composed of synthetic resin, fillers, pigments, curing agents and auxiliaries.
Powder coating powder, as a new type of environment-friendly coating, has the advantages of small environmental pollution, low consumption of resources and energy, low production cost and high production efficiency.
The production principle of powder coating powder is actually very simple. Solid materials such as synthetic resin, fillers, pigments, curing agents and additives are added to the mixer in a certain proportion and formula.
The pre-mixing process should be operated in the absence of water or other solvents.
The material passed through the mixer is melted through the extruder at high temperature, mixed completely, and then enters the cooling press to cool and press into thin sections. After the thin section enters the cyclone separator, the separated coarse powder is screened to get the finished powder coating powder, and the fine powder is recovered.
Because the powder coating powder does not involve any chemical reaction in the production process, it is a pure physical process, so it is more environmentally friendly compared with other types of coating products.
