Detailed Product Description

Profile:
  High-temperature calcining improves the physical performance (whiteness, density, porosity, and bulkiness), chemical performance (adsorptivity, reactivity), and optical, electrical, and magnetic properties of coal-measure hard kaolin. Calcined kaolin is widely used in paper, paints, and coatings.

Uses:
1)In Coating     
Calcined kaolin improves structural strength in both water- and oil-based paints. It offers good dispersion, chemical stability, corrosion resistance, fire resistance, scrubbing resistance, and mechanical characteristics. It can further improve the storage stability, brushability, moisture assistance, and impact resistance of paints and coatings. It resists floating and blooming in pigments, improves covering power, durability, and heat and weather resistance, and offers good opacity and adsorption. It can partially replace titanium white. The use of calcined kaolin in inner and outer wall coatings, high-end paints, inks, and marker line paint can directly cut costs. 

2)In rubber products
Calcined kaolin is used as a filler in the rubber industry, and can improve products' physical and chemical properties. It has a significant reinforcing action, is an electrical insulator, and can improve tear resistance, tensile strength, aging resistance, and corrosion resistance. It can enhance solubility in latex, increase vulcanization hardness and abrasion resistance, and boost flex life and smoothness. It can cut costs when used as a replacement for such costly materials as abrasion-resistant carbon black, ordinary carbon black, white carbon black, aluminum silicate carbon black, and magnesium oxide. 

3)In ceramics
Use of calcined kaolin ensures that products will have a white, fine-textured, glossy surface. It can boost mechanical strength and reduce defect rate. Calcined kaolin is suitable for use as a blank material and glaze in everyday ceramics, construction ceramics, corrosion-resistant chemical engineering ceramics, crafts and art ceramics, sanitary ceramics, and high and low piezoelectric ceramics. 

4)In glass products
Calcined kaolin replace costly alumina. When used as a filler in white glass products, it can improve product quality and reduce production costs. 

5)In plastics
Calcined kaolin can enhance the strength of greenhouse film, ground film, cable insulation, and PVC pipe (sheet). Apart from whiteness and electrical insulating properties, it also allows diffuse light transmission and blocks infrared when used in plastic film. It can reduce cost when used as a bulk filler. 

6)In papermaking
The laminar structure of calcined kaolin makes it a useful coating pigment in papermaking. Apart from good covering ability and relatively high luster, calcined kaolin's porous structure can increase the porosity, soft bulk, and smoothness of coating layers. It lends opacity and flexibility to paper, improves ink adsorption, enhances luster, and reduces printing spots. 

7)In fire-resistant materials
Calcined kaolin is used for linings in metallurgy and chemical engineering. Uses include kiln linings, high-temperature fusion crucibles, and various types of bricks, tiles, rods, plates, and non-standard-shape fire-resistant and heat-resistant materials.

8)In pesticides and petrochemicals
Calcined kaolin particles are covered with tiny pores that give this material tremendous adsorptivity. Calcined kaolin can be used in pharmaceuticals and pesticides. Because it is neutral and has a high silicon content, it can be used in silicon fertilizer, and can also be used as an animal feed additive. It is used as a catalyst in petroleum refining. It possesses relatively high basal activity, strongly resists contamination by heavy metals, and offers good catalytic activity and selectivity.
