6250 сетка кальцинированный каолин

1. Superfine particle size, general - 2 μ The content of M is 85% ~ 90%, and the high-quality Z-1 can reach - 2 μ The content of M is more than 92%, which is the finest calcined kaolin in China. 325 mesh sieve residue is very low, so it can improve the smoothness and luster of the paper;

2. The texture is pure, the content of kaolin in the product is more than 97%, and the content of impurities is very low;

3. It has excellent dispersibility and fluidity, with viscosity concentration up to 86.7%, and can be equipped with papermaking coating with solid content of more than 60%, especially suitable for papermaking of high-speed paper machine;

4. It has excellent anti settlement performance. Tzj-z-1 series products have ultra-fine particle size, loose bulk density of only 0.25-0.35t/m3, excellent thixotropy, and good flake structure, so it has excellent suspension performance in coatings;

5. Low abrasion value. The calcination temperature of TZJ – Z-1 series products is strictly controlled in the manufacturing process, so the mullite content in the products is very low, so the wear of the coating paper machine is small.
