Product Description
Kaolinite (English: Kaolinite), also known as Guanyin clay, eel mud, bentonite, bentonite, sweet clay, bentonite, pottery clay, porcelain clay, white clay, known as kaolinite in mineralogy, is a kind of The island silicate mineral of aluminum is in the form of white ooze with fine particles that look like flour. Its chemical composition is quite stable and it is known as the "universal stone". It is extensively used in various industrial applications such as ceramics, paints, cosmetics, pharmaceuticals, and agriculture due to its desirable properties including chemical inertness, adsorbency, and non-swelling capabilities.
The English name "Kaolinite" is derived from the name of a village near Jingdezhen in Jiangxi Province, China.
Calcined kaolin is produced by calcining (roasting, sintering) kaolin or kaolinite (flint clay). Calcining is mainly carried out in rotary kilns, but can also be carried out in vertical kilns, ring kilns and tunnel kilns. The alumina content is different, and the refractoriness is also different accordingly. Depending on the chemical composition, varying degrees of corrosion and acid resistance can be achieved. Clay is available as raw material with a fineness of 0 to 25 mm or 0 to 50 mm, or in granularity and fineness of the finished refractory material.

(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 . 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 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 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 : In the production of cable rubber and plastics, kaolin 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) Fire-proof Industry : It can greatly improve the specific volume resistance, dielectric strength, retardant effectiveness with its good dispersion and reinforcement.
