Eco-friendly factory direct special white calcined kaolin

Quality of pure white kaolin with a high, soft, easily dispersed suspension in the water, good plasticity and high adhesion, excellent electrical insulation properties; has good acid-soluble, low cation exchange capacity, better fire resistance and other physical and chemical properties. Therefore kaolin has become papermaking, ceramics, rubber, chemicals, paints, pharmaceuticals and defense industries and dozens of mineral raw materials necessary. Kaolin in the paper industry is very wide application. There are two main areas, one in the paper (or papermaking) used in the process of packing, and the other is used in the process applied to the surface of the pigment. For general cultural paper, packing paper accounts for 10-20% by weight. For coated paper and paperboard (including lightweight coated paper, coated paper and coated paperboard), in addition to packing, but also we need to paint, fill, kaolin proportion of pigments for paper weight of 20-35%. Kaolin used in paper making, paper can give a good performance and good coating coverage luster performance, but also increase the whiteness of the paper, opacity, smoothness and printability, greatly improving the quality of the paper. Main advantages: 1, due to the high purity Kaolinite content of harmful elements very end, so not only deal with simple process, and high whiteness, whiteness can reach an average of 93%, the maximum brightness can reach 97%, can be used in papermaking improve the whiteness of coated paper, partially replace titanium dioxide, can reduce costs. 2, the sticky at high concentrations, up to 74%, dispersion, and natural and synthetic adhesives and other additives formulations have good compatibility, can coatings with good rheological properties, particularly suitable for machine coating and other requirements within high solid content coating machine. 3, wear value is low, the material is heated evenly, and never will be partial over-burning, tested abrasion value is only 3.6mg / 2000 times.
