Product Description

 Resistance Kaolin vary from  325mesh to 4000mesh

Product Description

Kaolin is a kind of kaolinite mineral clay and clay rock that has good plasticity and fire resistance.

Kaolin application mainly used for paper making,ceramics,refractory materials, secondly used in paints, rubber filler, enamel glaze and white cement raw material, some used in plastics, paint, paint, grinding wheel,pencil, daily cosmetics,soap, pesticide

medicine, textile, oil, chemical industry,building materials, and so on.

Kaolin is divided into: washed kaolin, calcined kaolin, lightweight kaolin

Kaolin is a mixture of inorganic nonmetal, calcined kaolin is calcined kaolin in sintering furnace to a certain temperature and time, the physical and chemical properties which has a certain change, in order to meet certain requirements.

The main specification: 200mesh 325mesh 400mesh 600mesh 800mesh 1250mesh 3000mesh 4000mesh etc

The difference of Calcined Kaolin with Washed Kaolin

Firstly, calcination of kaolin involves chemical changes in its crystal structure and original soil during calcination, while washing kaolin with water only results in physical changes and does not alter the properties of the original soil;

Secondly, the whiteness of calcined kaolin is relatively high, while the whiteness of washed kaolin does not significantly increase, resulting in a significant difference;

The third type of calcined kaolin mainly refers to hard kaolin. The original soil has no cohesiveness and cannot be directly used as a raw material for papermaking or refractory materials. It needs to be calcined and used. However, the original soil of washed kaolin has cohesiveness and can be directly used as a binder for refractory materials or paper fillers. In general, Baidu is better for calcining kaolin and can be used in the papermaking industry, but the corresponding cost is also relatively high.

Applications

Usage: In industries such as coatings, construction, papermaking, plastics, rubber, chemicals, agriculture, etc.

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