325 mesh calcined kaolin/washed kaolin for ceramic
On the area, it appears unremarkable. A platy comfortable white clay mined and processed by EPT in ZheEPTng , kaolin can disguise just how versatile and essential it is to a varied listing of EPT by visual appeal alone.
1. High brightness, particle size and tremendous opacity, as pigments and fillers in paper business, kaolin can increase the smoothness, gloss,protection and opacity to lessen or eradicate TiO2 to minimize down value whilst mainXiHu (West Lake) Dis.Hu (West Lake) Dis. important qualities.
two. Minimal abrasion, effectively lowering knife usage to reduce down cost.
3. Favorable viscosity and good compatibility with numerous chemical brokers.
Uses
Kaolin is a platy white clay that is chemically inert, nonabrasive and possesses a variety of characteristics that make it desirable 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 several other people.

Kaolin Application
1) Paper- making Sector: It is mostly used in the coating paper, artwork paper, white board paper, corrugated paper, coating white board paper Solid coated paper and so on . It is far more applicable in gravure printing for its good free depth and elasticity which can ensure less leaks and places.
two) Coating Business: Its whiteness, smoothness and non- transparency can be nicely improved by incorporating Kaolin to the pigment in the process of coating paper and paper board.
three) Oil and Paint Business: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 properly improved by including Kaolin because it can make the cast enamel far more adhesive to iron billet. Kaolin also plaEPTthe role of anti-precipitating when utilized in h2o paint. It is also a kind of very good inorganic laEPT agent.
four) Rubber Industry: In the generation of cable rubber and plastics, kaolin can improve the abrasiveness, hardness, anti-shock and extension rate.
5) Plastic Market: It plaEPTthe role of reinforcement with its very good dispersion. It also can quit the infrared raEPTof wavelength from seven-14um in thick movie so as to boost the temperature in the drop.
six) Ceramics: It is commonly used in higher and lower voltage ceramic, all sorts of ceramic billet and enamel It is also applied in all kings of refractory.
7) Cable Business: It can significantly boost the particular quantity resistance, dielectric power, retardant efficiency with its good dispersion and reinforcement.
