In order to separate non-clay minerals and organic matter such as quartz, feldspar, mica, iron minerals, titanium minerals and other non-clay minerals and organic matter in kaolin, and produce kaolin products that can meet the needs of various industrial fields, in addition to using gravity separation, flotation, magnetic separation, etc. to purify kaolin and remove impurities, sometimes it is necessary to use chemical bleaching, ultrafine stripping, calcination, surface modification and other deep processing methods to treat kaolin.
use
Due to the high purity of kaolinite and the very low content of harmful elements, it is not only simple to treat the process, but also has high whiteness of the product, with an average whiteness of 93% and a maximum whiteness of 97%. High viscosity concentration, up to 74%, good dispersion, and natural and synthetic adhesives and other additives in the formula have good compatibility, can make the coating have good rheological properties, especially suitable for in-machine coating and other coating machines requiring high solid content.
