Product Description

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.

Compared with the non calcined kaolin and calcined kaolin, calcined kaolin with reduced water content, silica and alumina content increased three, the activity increases, changes in the structure, the particle size is small and uniform, compared with non calcined kaolin filled NR rubber, vulcanized low temperature characteristic curve of calcined kaolin filled NR compound consistent.

- Used in high and low voltage ceramic, all kinds of ceramic billet and enamel; It is also applied in all kings of refractory.

- Used in coating paper, art paper, white board paper, corrugated paper, coating white board paper; Cast coated paper and so on . It is more applicable in gravure printing for its good loose depth and elasticity which can guarantee less leaks and spots.

-Used in coating Industry, it can be well improved by adding Kaolin to the pigment in the process of coating paper and paper board.

- Used in the production of cable rubber and plastics, kaolin can improve the abrasiveness, hardness, anti-shock and extension rate.
