China Washed Kaolin 600 Mesh Kaolin Kaolin for Floor Tile

Low price washed kaolin 600 mesh for floor tile
1,Introduction

(1)The main composition is kaolinite, content of about 90% or so Particle size less than 22 mm

(2)Kaolin easy to disperse in water or other liquids, have satiny feeling ,earthy taste. Density is about 2.54-2.60g/cm3 melting point about 1785C

(3)Kaolin has advantages of high brightness low impurity and strong chemical inertia and easy to disperse in water and oil based structure.

2,The feature of kaolin

Associative viscosity and contact degeneration drying performance sinterability firing shrinkage refractoriness suspension property and dispersion adsorption and commutativity chemical stablility electronic insulativity

3,Application

(1)Kaolin widely used in ceramics glass paper rubber daily chemical industry agricultrure and so on

(2)calcined kaolin clay is mainly used for manufacturing high-quality refractory products refractory castable sagger klin furniture crucibles ceraWheel & Caster mic fiber precison casting sand ceramics products ,etc.
