Product Introduction : It is a crystalline material with a triclinic form in pseudo-hexagonal plate and its structure can be regarded as a gibbsite Al(OH)3 layer bonded to a siloxane layer. It has a Mohs hardness of 2.8, a density of 2.6 and a refractive index of 1.56. It is fairly acid-resistance or base-resistance, however, it is ready to absorb moisture and must be dried before using.

Application

1) Paper- making Industry: It is mainly applied in the coating paper, art paper, white board paper, corrugated paper, coating white board paper; cast coated paper and so on with its properties of high whiteness, good particle distribution and excellent hiding rate to improve its oil absorption and maintain its good printing luster. Its good hiding power and luster can make good loose depth and printing quality. It is more applicable in gravure printing for its good loose depth and elasticity which can guarantee less leaks and spots.

2) Coating Industry: Its properties of good suspension, easy dispersion, excellent hiding power, high whiteness and pure color can well improve its stability, coating and printing quality, anti-moisture absorption and shock resistance, as well as color floatation resistance and floating. Its whiteness, smoothness and non- transparency can be well improved by adding Kaolin to the pigment in the process of coating paper and paper board.

3) Oil and Paint Industry: It has the properties of low oil absorption, good dispersion, high thermal resistance, low temperature resistance, ultraviolet resistance, oxidative degradation resistance as well as good electric insulation. It can well improve the viscosity, fluidity, anti-precipitation and so on. The enamel glaze slip’ properties of floatation, viscosity, adherence and thermal casting resistance can be well improved by adding Kaolin because it can make the cast enamel more adhesive to iron billet. Kaolin also plays the role of anti-precipitating when used in water paint. It is also a kind of good inorganic latex agent.

4) Rubber Industry: It plays the role of reinforcement with its good viscosity and dispersion, and can well improve the effect of vulcanization, increase the addition for its good crosslink with rubber. In the production of cable rubber and plastics, it can improve the abrasiveness, hardness, anti-shock and extension rate.

5) Plastic Industry: It plays the role of reinforcement with its good dispersion. It also can stop the infrared rays of wavelength from 7-14um in thick film so as to increase the temperature in the shed.

6) Ceramics: It is widely used in high and low voltage ceramic, all kinds of ceramic billet and enamel; it is also applied in all kings of refractory.

7) Cable Industry: It can greatly improve the specific volume resistance, dielectric strength, retardant effectiveness with its good dispersion and reinforcement.
