What's the difference between nano kaolin, washed kaolin and calcined kaolin? Where is the difference?
The purity of calcined kaolin is enough kaolin, after high temperature firing out after grinding of kaolin, in order to improve the whiteness and purification, the firing temperature according to customer's product requirements vary from 900 degrees to 1300 degrees are
Washed kaolin is the kaolin ore through water panning, coarse sand and impurities removed, usually grain size of 325 or more, 325, the size of the target is about 43 microns, that is, 43000 nm.
Nano kaolin means that the granularity of kaolin is reduced to nanometer scale, a nanometer equal to 1/1000 microns.
