Product Application:
 

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

Company Introduction:

    Inner Mongolia Tianzhijiao Kaolin Co., Ltd. is a new scientific and technological company established by listed companies Baotou Steel Rare-Earth Hi-Tech Co., Ltd. and Inner Mongolia Baotou Steel Hefa Rare Earth Co., Ltd. as the main initiators. With a registered capital of RMB 10 million, the Company was established in Ordos Jungar Banner Economic and Technological Development Zone which is rich in coal resources in March 2004.    
     It is mainly committed to the research and development, production and sales of calcined kaolin series products. The products are widely used in many industries such as papermaking, paint coating, high-performance concrete, wires and cables made from polymer materials, rubber and plastics, petroleum and petrochemicals.
     It was identified as the Jungar Banner kaolin research and development center by the Inner Mongolia Science and Technology Bureauin 2004,and established a technical cooperation relationship with Universities.    
    The Company carries out the independent research and development and has won seven national invention patents and six science and technology progress awards, and identified as the key high-tech enterprise in Ordos.    
    The ultrafine and ultrawhite calcined kaolin products of 4000-6250 meshes researched and produced by the Company have shown the outstanding performance in different industries, reaching the capacity of producing 200 tons of kaolin per day and 100,000 tons per year. The stability of the products has reached the international leading level.
