Our high quality kaolin in coal as raw material, selection, fine, cleaning, grading, calcine process to produce
Our high quality kaolin in coal as raw material, selection, fine, cleaning, grading, calcine process to produce 325 mesh, 1250 mesh, 2500 mesh, 5000 mesh and other products with different specifications. High brightness, high dispersion, high cover rate, which is widely used in papermaking, paint, rubber and other industries. Partially replace titanium dioxide.
Uage:
1. Paper industry: mainly used for coated paper, copperplate paper, white paper, corrugated paper, etc. Particle size distribution with high whiteness good characteristics of a good cover. Add in the paint coating paper and paperboard in the processing can improve the whiteness, smoothness and opacity, to improve the ink oil absorption. Maintain good print gloss.
2. The coatings industry: its advantage is that suspension is good, easy to disperse, covering performance, high brightness and the color is.
3. The rubber industry: mainly used as functional fillers, can partially replace white black carbon, play a reinforcing effect.
