Kaolin

الوصف

China clay or kaolin is a commercial clay composed principally of the hydrated aluminosilicate clay mineral .The commercial value of kaolin is based on the mineral’s whiteness and its fine but controllable, particle size which may be optimized during processing. Particle size affects the fluidity, strength, plasticity, colour and ease of dispersion. Able to offer Kaolin grades having premium brightness, fine particle size with controlled distribution range, fine particle size with low grit level and other specific properties as demanded by the application. Applications of Kaolin Kaolin has a range of applications which are grouped in three main areas: paper, ceramics and performance minerals. Demand is most in the manufacture of paper where it performs two separate function- as a filler to improve printing characteristics and as a coating pigment to enhance the surface properties of the paper such as the brightness, smoothness, gloss and ink receptivity etc. In the ceramics industry the main function of kaolin is to impart whiteness. Its major uses are in vitreous china sanitary ware, table ware, wall tiles, electrical porcelain. Kaolin is used in refractory where it is valued for its alumina content. Performance mineral applications use kaolin as fillers in paint, rubber, plastics and adhesives and sealants and pharmaceuticals. Other important uses include the manufacture of white cement and glass fibre.
