Ceramic addtives washed kaolin/calcined kaolin powEPTfor ceramic software
Kaolin is a variety of kaolinite mineral clay and clay rock that has great plasticity and fireplace resistance. ZheEPTng EPT supplies calcined kaolin and washing kaolin, with great high quality and rather aggressive value. EXiHu (West Lake) Dis.sting product requirements: kaolin 325 mesh, kaolin 800 mesh, kaolin 1250 mesh, kaolin 4000 mesh. Commonly materials ceramics, rubber, paint coatings, paper, coating, chemical EPT and other EPT.
Kaolin Attributes:
1. Large refractoriness.
two. Physicochemical stability.
three. Bulk density large .
4. Lower porosity.
5. Minimal drinking water absorption.
six. Entirely calcined
seven. Low impurity material.
eight. White or virtually white.

Calcined Kaolin Sequence
Under calcined kaolin produced by coal XiHu (West Lake) Dis.Hu (West Lake) Dis.e and aluminous rocks. Following the calcined modified, they are large brightness and good chemical stability, can be widely employed in paint and coating, papermaking, rubber, plastic, cable, ceramics and other fields.
Functions: Pure and substantial brightness, wonderful grain and reduced display residue, decentralized and nicely covering functionality and floating, not simple to precipitate. They can exchange lithopone and partly of EPTium dioXiHu (West Lake) Dis.de to lower the item expense.
Kaolin Application
1) Paper- generating Sector: It is primarily utilized in the coating paper, artwork paper, white board paper, corrugated paper, coating white board paper Solid coated paper and so on . It is much more applicable in gravure printing for its very good loose depth and elasticity which can guarantee less leaks and spots.
two) Coating Market: Its whiteness, smoothness and non- transparency can be effectively enhanced by adding Kaolin to the pigment in the method of coating paper and paper board.
3) Oil and Paint Industry:It can well improve the viscosity, fluidity, anti-precipitation and so on. The enamel glaze slip’ qualities of floatation, viscosity, adherence and thermal casting resistance can be properly improved by incorporating Kaolin since it can make the solid enamel far more adhesive to iron billet. Kaolin also plaEPTthe role of anti-precipitating when employed in drinking water paint. It is also a kind of great inorganic laEPT agent.
4) Rubber Business: In the creation of cable rubber and plastics, kaolin can boost the abrasiveness, hardness, anti-shock and extension fee.
five) Plastic Sector: It plaEPTthe position of reinforcement with its good dispersion. It also can quit the infrared raEPTof wavelength from 7-14um in thick movie so as to enhance the temperature in the shed.
6) Ceramics: It is commonly employed in large and low voltage ceramic, all sorts of ceramic billet and enamel It is also used in all kings of refractory.
seven) Cable Market: It can tremendously increase the distinct volume resistance, dielectric power, retardant efficiency with its very good dispersion and reinforcement.
