1.Description

Mohs hardness is 1 to 2, refractoriness is 1770 ~ 1790 ℃. It has the performance of high whiteness, soft quality, easy dispersion, good suspension, good plasticity, high adhesion and good electrical insulation. It has good anti-acid solubility, low cation exchange rate, good fire resistance and other physical and chemical properties. It has become a necessary mineral material for dozens of industries, such as paper making, ceramics, rubber, chemicals, coatings, medicine and national defense.

2.Technical Indexes

3.Features

Kaolin can increase the vitrification temperature, the strength and the modulus, and the insulation performance in plastics.

Rubber hose has tensile strength, tensile elongation, tensile strength of permanent deformation rate, where kaolin powder replaces light calcium in rubber, Shao Er type A etc. The main technical indexes can reach the requirements of relevant standards. The adhesive with addition of Kaolin is easy to mix, and also conducive to the dispersion of carbon black in the adhesive, the finished surface is delicate and smooth.

Kaolin used in coating is the main role of filler and pigment substitutes, because it has a chemical inertness, high coverage, liquidity of ideal and suspended, the cost is low, the characteristic such as colour white, can reduce the requirement of expensive dyes, improve the quality of the coating hardness, improvement of coating.
