La description


APPLICATION for ceramics:

 

  Kaolin has a wide range of application is the ceramic industry, and is commonly used in whiteware products, insulators, and refractories. In whitewares, kaolin viscosity improves the molding ability of pre-heated materials, offers a stronger finished product, and a smooth surface finish such as those found in tile and porcelain. Kaolin is becoming more prevalent in porcelain insulation due to its high dielectric strength and as an alternative to the scarcer resources high in potash feldsparic materials. Kaolin is used in refractories due to its extremely high fusion point, low water content, and high green strength. Ceramics produced with kaolin have a wide variety of uses, mainly as a metal substitute. Ceramics are becoming more prevalent in aerospace due to their refractory strength. Ceramic knives stay sharper longer and have better durability than metal. Toyota has created an all ceramic car engine capable of running at much higher heats. Recently there have also been advances in bio-ceramics that may lead to new and better teeth and bone replacements

 

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.

 The modern materials industry uses calcined kaolin in the production of composite materials. It is compatible with both metallic and nonmetallic materials, while offering performance superior to that of metallic and nonmetallic materials in some respects. Calcined kaolin provides good mechanical strength, impact resistance, radiation resistance, heat resistance, and corrosion resistance. Because of these properties, it can be used for high-temperature combustion chambers, nozzles, and cylinders in autos, aircraft, and rockets, etc., and is used in other special and high-strength ceramics.

7.In cosmetics
Calcined kaolin is used as a white body pigment employed in facial masks, facial powder, toothpaste, and other everyday products. It can cut costs when used instead of titanium white
