  • Kaolin | clay | Britannica

    In filling, the kaolin is mixed with the cellulose fibre and forms an integral part of the paper sheet to give it body, colour, opacity, and printability In coating, the kaolin is plated along with an adhesive on the paper’s surface to give gloss, colour, high opacity, and greater printability Kaolin used for coating is prepared so that most of the kaolinite particles are less than two micrometres in diameterThe simplest process is called air flotation or the dry process The properties of the finished product depend to a large extent on those properties inherent in the crude kaolin In the dry process operation, a deposit must be chosen with desirable properties of color and relatively low content of grit ( > 44 µ) The crude kaolin is transported to the mill where the large chunks are reduced to about egg size by rollKaolin WetProcessing Helals
