INDUSTRIES

Kaolin In Ceramic Industries

The word ceramic derived from Greek word “Keramos” originally meant fired and fused common clays. The manufacturing consists of mixing China clay, quartz or silica and other types of clay, feldspar and some flux with water. This mixture is well ground, thoroughly stirred up, filtered, pressed and molded into the required shape. It is then dried and fired at a temperature raging from 1200⁰ to 1500⁰ Celsius.
Paper

Kaolin In Papper Industries

Kaolin serves as a paper coating which enhances paper’s appearance by adding brightness, smoothness and gloss. It also improves printability. In paper industry Kaolin is used as a filler as It increases opacity, printability, gloss and brightness. Approximately 40 percent of the kaolin produced worldwide is used in the filling and coating of paper. In coating, the kaolin is plated along with an adhesive on the paper’s surface to give gloss, color, high opacity, and greater printability. Kaolin used for coating is prepared so that most of the kaolinite particles are less than two micrometers in diameter.
Paint

Kaolin In Paint Industries

Kaolin is used in white paint. It is also used in oil paint owing to its high oil absorption. Kaolin is used as an extender or a suspending agent in oil paints and as pigments in water paints or distempers. Kaolin has properties such as white color, easy dispersion, anti-settling and chemical inertness, which are the main criteria for its use in paint industries.
Rubber

Kaolin In Rubber Industries

Considerable quantity of kaolin is used for filling rubbers to improve its mechanical strength and resistance to abrasion. For this purpose, the clay used must be extremely pure kaolinite and exceedingly fine grained.
