325 mesh calcined kaolin/washed kaolin for ceramic
On the surface area, it seems to be unremarkable. A platy comfortable white clay mined and processed by EPT in ZheEPTng , kaolin can disguise just how adaptable and crucial it is to a various checklist of EPT by appearance alone.
one. Large brightness, particle measurement and tremendous opacity, as pigments and fillers in paper business, kaolin can improve the smoothness, gloss,coverage and opacity to reduce or eradicate TiO2 to minimize down price although mainXiHu (West Lake) Dis.Hu (West Lake) Dis. crucial properties.
two. Lower abrasion, successfully lowering knife intake to lower down price.
three. Favorable viscosity and very good compatibility with various chemical brokers.
Utilizes
Kaolin is a platy white clay that is chemically inert, nonabrasive and possesses a quantity of characteristics that make it attractive for use in a variety of EPT, incXiHu (West Lake) Dis.Hu (West Lake) Dis. paper and paperboard, paints and coatings, plastics, wire and cable and in concrete among numerous others.

Kaolin Application
1) Paper- creating Business: It is largely applied in the coating paper, art paper, white board paper, corrugated paper, coating white board paper Cast coated paper and so on . It is far more applicable in gravure printing for its good free depth and elasticity which can guarantee less leaks and spots.
two) Coating Industry: Its whiteness, smoothness and non- transparency can be properly improved by including Kaolin to the pigment in the process of coating paper and paper board.
3) Oil and Paint Sector:It can nicely enhance 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 introducing Kaolin because it can make the solid enamel a lot more adhesive to iron billet. Kaolin also plaEPTthe part of anti-precipitating when used in water paint. It is also a variety of excellent inorganic laEPT agent.
four) Rubber Industry: In the production of cable rubber and plastics, kaolin can boost the abrasiveness, hardness, anti-shock and extension charge.
5) Plastic Business: It plaEPTthe position of reinforcement with its good dispersion. It also can cease the infrared raEPTof wavelength from seven-14um in thick film so as to enhance the temperature in the shed.
6) Ceramics: It is broadly utilized in substantial and lower voltage ceramic, all sorts of ceramic billet and enamel It is also used in all kings of refractory.
seven) Cable Industry: It can significantly increase the certain quantity resistance, dielectric power, retardant performance with its very good dispersion and reinforcement.
