Product description, Product introduction: Kaolin is White or light yellow powder, the main components is aluminum silicate (Al2O3,2SiO2,2H2O) Physical properties of Kaolin: Mohs Scale Hardness is from 2 to 2.5,density is 2.6 g/cm3 ,and refractoriness is from 1750 to 1790 degree centigrade.Used as friction materials, Kaolin can improve the process performance of friction materials, reduce the shrinkage rate of products , and improve the friction performance of friction materials in 400-600 , reduce the cost. Kaolin is made by crushed kaolin ore .Kaolin is used in Brake pad Drum brake or clutch, The recommended regular consumption of kaolin is from 2% to 8%. The character of Kaolin: Kaolin is named by the kaolin village in Jingdezhen in China where it was found near China, it is clay or clay rock which is mainly of kaolin clay mineral Kaolinite radial clay minerals including kaolinite, halloysite, di stone, Pearl chinastone, water mica, etc. Kaolinite is of soft and hard kinds.Kaolin has many excellent properties. Such as: water absorption, plasticity, suspended, strong cohesive force, high refractoriness, good insulation and chemical stability, and good sintering performance.Add some kaolin in the composition of friction materials, can reduce the brake noise and reduce the heat recession.

The well-controlled processes ensure the GB series have no coarse particles and maintains an absolute minimum of 325 mesh residue, so the end user can achieve a high Hegman grind. The GB series pigments also have high brightness, strong hiding powder and superior dispersibility, and it is widely applied in latex paint, powder coating and electrophoresis coating. Its main benefits are: It is the best extender of titanium dioxide with excellent opacity that can improve efficiency and cut costs by partly replacing titanium dioxide; It can easily disperse in water based systems; It offers superfine particle and with excellent anti-settling property; It is inert to most acids and alkaline at ambient temperature and offers good anticorrosive capabilities.

Calcined Kaolin: Calcined Kaolin is representative of high quality hard clay in China. After calcined , Al2O3 contents about 44-46%, Fe2O3 contents 2% max, the composition is stable , uniform and dense structure, with the white colour after calcined, it is the good raw material in the refractory industry.
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.
Kaolin is a kind of nonmetallic minerals, is a kind of give priority to with the family of kaolinite clay mineral clay and clay rock.For white and delicate, also called dolomite.Named after the deep jingdezhen kaolin village in jiangxi province.Its quality pure kaolinite was white and delicate, soft soil, it has good plasticity and the physical and chemical properties such as fire resistance.Its mineral composition mainly consists of kaolinite, halloysite, hydromica, illite and montmorillonite, quartz and feldspar mineral composition.Kaolin application is very extensive, mainly used for paper making, ceramics and refractory materials, secondly used in paints, rubber filler, enamel glaze and white cement raw material, a few used in plastics, paint, paint, grinding wheel, pencil, daily cosmetics, soap, pesticide, medicine, textile, oil, chemical industry, building materials, national defense and other industries. Kaolin is mainly used for paper making, ceramics and refractory, kaolin second used in paints, rubber filler, enamel glaze and white cement raw material, kaolin small amount used in plastics, paint, paint, grinding wheel, pencil, daily cosmetics, soap, pesticide, medicine, textile, oil, chemical industry, building materials, national defense and other industries.
