PRODUCT INFORMATION
6250 mesh calcined kaolin is the product of calcined coal-measure kaolin, which has the characteristics of high whiteness, fine particles, porous surface and higher than the surface. Therefore, it has a high suspension in the solution, so it has slurry concentration stability when used for paper filling operation. When used for coating operation, it has low abrasion value in coating process. It can prepare high solid content coating, which is suitable for high-speed coating. After coating, paper has the advantages of good light scattering performance, excellent ink absorption, and amazing printing adaptability.
