800 Mesh Washed Kaolin for Papermaking High Whiteness

800 mesh washed kaolin for papermaking high whiteness

Kaolin has a variety of apps which are grouped in 3 major locations: paper, ceramics and refractories.

Demand is most in the manufacture of paper the place it performs two separate features- as a filler to enhance printing qualities and as a coating pigment to boost the surface area properties of the paper these kinds of as the brightness, smoothness, gloss and ink receptivity and many others.

In the ceramics business the principal perform of kaolin is to impart whiteness . Its significant utilizes are in vitreous china sanitaryware, desk ware, wall tiles, electrical porcelain #8230

Kaolin is employed in refractories exactly where it is valued for its alumina material.

Performance mineral applications use kaolin as fillers in paint, rubber , plastics and adhesives and sealants and prescription drugs.

Other EPTant employs incEPT the manufacture of white cement and glass fibre.
