Important factors determining the powder coating rate of Yongkang powder coating
Source: FounderDate: June 29, 2024; Browse:0
The quality of Yongkang powder coating products is unparalleled, so increasing the powder coating rate can maintain quality. Yongkang Xingshun Plastic Powder Co., Ltd., a manufacturer of steel wooden door plastic powder, specializes in producing powder coatings, steel wooden door plastic powder, plastic powder, with superior quality and affordable prices. Welcome to call and purchase.
The powder coating rate is directly related to the resin content, charged additives, fillers, powder particle size distribution, etc.
Increase the amount of resin and reduce the amount of filler used. Choose resins with good electrical properties. Epoxy is easier to powder, while some manufacturers do not powder polyester, making it difficult to powder polyester (by grinding epoxy and polyester separately into powder spray plates). Friction guns have significantly better leveling than electrostatic guns, and can spray thicker coatings.
Adding an appropriate amount of conductive additives to the formula can increase the charge on the powder particles. There is a strong electric field in the area between the high-voltage electrostatic spray gun and the workpiece, and the air is ionized to produce billions of ions. When the powder particles of the charging agent pass through this area, they are polarized, which can capture more negative ions and carry more charges. For areas such as grooves and blind spots, due to the weak Faraday effect power lines, powder particles with higher charges can reach the surface of the workpiece by their own force, thereby improving the powder coating in these areas.
The fineness and dispersion of fillers are closely related to powder application. The precipitation powder is higher than that of ordinary ultrafine heavy barium, and barium sulfate is better than calcium carbonate.
Control the particle size distribution of the powder, the narrower the better: Reasonably controlling the particle size of the powder (which is relatively difficult), in our actual production, we only need to adjust the speed of the main and secondary grinding of ACM. A powder particle size of 40-50UM is considered suitable, and a narrower distribution is better.
