Kaolin application 1, kaolin industrial use Kaolin has become a paper, ceramics, rubber, chemicals, coatings, medicine and national defense, and dozens of other industries essential mineral raw materials. Ceramic industry is the first application of kaolin, a large amount of industry. The general dosage is 30% ~ 20% of the formula. Kaolin in ceramic effect is the introduction of Al2O3, is conducive to the formation of mullite, to improve its chemical stability and strength of sinter, in firing kaolin soil derived from the decomposition of mullite, forming the main frame of the strength of the green compacts, can prevent the products from deformation, firing in a wider temperature range, also can make the green body with certain whiteness. At the same time, kaolin has certain plasticity, adhesive, suspension and ability to bind endowed with porcelain clay, glaze good formability, make ceramic mud blank to billet car and grouting, easy to shape. If used in the wire, can increase the insulation, reduce the dielectric loss. Ceramic not only on kaolin clay plasticity, binding, drying shrinkage, dry strength, sintering shrinkage, sintering properties, refractoriness and burn whiteness have strict requirements, but also relates to the chemical properties, especially the presence of color elements caused by iron, titanium, copper, chromium, manganese and other, to burn after the brightness decreases, produce spots. Of kaolin particle size is smaller, the better, the porcelain clay has good plasticity and dry strength, but the rapid casting, accelerate the grouting speed and the dehydration rate of the casting process, the need to improve the batching particle size. In addition, kaolinite crystallization degree of difference, will also significantly affect the process performance of the porcelain, crystallization degree, plasticity, binding capacity is low, drying shrinkage of small, high sintering temperature, the impurity content also reduced; on the contrary, the plasticity is high, dry shrinkage of large, low sintering temperature, corresponding impurity content is also high. 2, kaolin in the field of cosmetics applications Kaolin is also known as the white porcelain, is a kind of clay mineral, usually white. In beauty, kaolin is usually used on the mask, it can absorb the oil and waste of the skin, clean the skin to remove dirt, and the town of Jingan to ask the fragile skin. The loss of water and nutrients from the mineral supplement in natural mud, balance oil secretion, make the skin more smooth, more flexible.
