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.


Compared with the non calcined kaolin calcined kaolin, calcined kaolin with reduced water content, silica and alumina content increased three, the activity increases, changes in the structure, the particle size is small and uniform, compared with non calcined kaolin filled NR rubber, vulcanized low temperature characteristic curve of calcined kaolin filled NR compound consistent. Shore A hardness constant, higher tensile strength, physical properties of both non transparent sole to sports shoes industry standards.

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.

The day before, rubber, plastics, ceramics, cement, artificial leather from refractory materials, chemical industry and agriculture are not widely used. 

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.

kaolin  is a kind of calcined kaolin with high whiteness and ultra-fine particle size.it can partly replae expensive titanium pigment,improve the effect of the use of titanium,can improve the paper whiteness,glossiness,smoothness,and opacity,improve the printing ink absorbency

1.As extension agent of titanium dioxide, calcined kaolin is applied in such fields as water-based paint, paint, putty, and sealant. On one hand, with good light scattering, it can provide good covering property, partially replacing expensive titanium dioxide, and reduce coating cost. On the other hand, with high whiteness, high dispersibility, and stronger chemical inertness, it can adjust coating's gloss, and improve coating system's storage stability, pigment's anti-floating color, and coating's weather resistance, acid resistance, and alkali resistance. In particular, it is essential to prepare low-VOC and high solid content coating

2. It replaces titanium dioxide partially and improves the usage result of titanium dioxide in paper coating applications and enhance the brightness, glossiness,smoothness, opacity and improve the ink absorption ability, printing adaptability and printing gloss of paper.General used in coated paper, art paper, coated manila, newspapers, thermal paper, etc

3.It is with advantages as high volume resistance, good compatibility with basic material, good dispersibility, high pureness, and strong chemical inertness, so that cable insulation materials'insulating property, mechanical property, processing rheological property, ageing-resistant performance

4.Using calcined kaolin as extension agent of titanium dioxide has become a frequently-used method for many systems. calcined kaolin is low in cost and excellent in performance (such as easy for color modulation, good dispersibility, good chemical stability, difficult of changing color), and easy for processing.
5.Used for improving air impermeability of rubber plug. because of chemical inertness of kaolin, rubber's ageing resistance and chemical stability can be enhanced effectively,meanwhile,it can enhance color and coating strengt
