Powder coatings are a very important part of the domestic construction industry. In recent years, the rapid domestic development has brought a huge market to the powder coating industry. Barium sulfate is a very important chemical raw material in powder coatings. The nano-level ultrafine barium sulfate produced by our company Yichang Huahao New Materials can improve the quality of powder coatings and reduce costs!
1. Control the particle size of powder coatings, the narrower the better.
The median particle size of nano-barium sulfate produced by our company Yichang Huahao New Materials can reach ≤0.1um, and it can also be produced according to customer requirements. Meet the high quality requirements of various powder coatings!
2. Increase resin content.
Increase the amount of resin and reduce the amount of filler. Choose resins with good charging properties. Epoxy is better for powdering. Some manufacturers do not powder for polyester, and some manufacturers have more difficult to powder (epoxy and polyester are ground separately. Powder spraying plate), the leveling of the friction spray gun is obviously better than that of the electrostatic gun, and the friction gun can spray a thicker coating, the coating does not have the shortcomings of the high-pressure gun such as blooming and large orange peel.
3. Reasonable selection of fillers.
Filler fineness and dispersion are closely related to powdering. The powder on the precipitate is higher than that of general ultrafine heavy barium, and barium sulfate is better than calcium carbonate.
Fourth, increase charging additives.
Add an appropriate amount of conductive additives to the formula (mechanism of action: allow the powder particles to carry more charges. There is a strong electric field in the area from the high-voltage electrostatic spray gun to the workpiece, and the air is ionized to produce hundreds of millions of ions, increasing The powder particles of the electrical agent are polarized when they pass through this area, and it can capture more negative ions and carry more charges. For the dead corners and other parts of the groove, the power line is weaker due to the Faraday effect, and the ones with more charge at this time The powder particles can reach the surface of the workpiece by their own strength, thereby improving the powdering of these parts.
Yichang Huahao New Material Technology Co., Ltd. is a joint stock of our company, Shandong Guoci, and Sakai Chemical of Japan. It is the largest barium salt manufacturer in China. The company has its own toxic heavy stone and barite mines, with the best quality and the lowest cost. The raw materials, Japanese process technology, high utilization rate and high purity of barium sulfate. Annually produce 20,000 tons of precipitated barium sulfate and 30,000 tons of nano-barium sulfate.
