Kaolin is a mixture of inorganic nonmetal, calcined kaolin is calcined kaolin in sintering furnace to a certain temperature and time, the physical and chemical properties which has a certain change, in order to meet certain requirements.It is widely used in Ceramics, rubber, plastics, leather, cement, refractory materials, chemical industry and agriculture .
Specifications
6250 mesh calcined kaolin clay
6250 mesh white 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, used for paper filling operation slurry concentration stability.Used for coating operation, coating process abrasion value is low, can prepare high solid content coating, suitable for high-speed coating, after coating paper light scattering performance is good, ink absorption is good, printing adaptability.
Applications: Paint, paper making, ink pigment
