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.
Graphite introduction Graphite is an allotrope of carbon element, each carbon atom of the neighboring link also three carbon atoms (arrangement is multiple hexagon honeycomb) by covalent bonds with the covalent molecule is formed. Because each carbon atom emits an electron, the electrons are free to move, so the graphite is a conductor. Graphite is one of the most soft minerals, and its use includes the manufacture of pencil cores and lubricants. Graphite application 1, as a refractory material: graphite and its products have properties of high - strength, high temperature resistance, mainly used to produce graphite crucible in the metallurgical industry, in steelmaking in graphite is usually used for the protection of steel ingot agent, metallurgical furnace lining. 2, as the conductive material: used for manufacturing electrode, carbon brush, carbon rod, carbon nanotubes, mercury is the cathode in electrical industry, graphite gaskets, telephone parts, TV picture tube coating. 3, as wear-resistant lubricating material: Graphite in the mechanical industry as a lubricant. Lubricating oils are often not used in high speed, high temperature and high pressure conditions, and graphite wear resistant materials can be used at high sliding speed in 200~2000. Many of the devices that transport corrosive media are widely used in the piston cup, seal rings and bearings, which are widely used in graphite materials. Graphite is many metal processing (drawing, drawing) the good lubricant. 4, graphite has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability characteristics, which is widely used in the manufacturing of heat exchanger, reaction tank, condenser, the burning tower, absorption tower, a cooler, a heater, a filter, a pump device. Widely used in petrochemical, wet metallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials. The corrosion resistance of the different types of non transparent graphite is different because of the different resin. Such as phenolic resin impregnated are acid, but not alkali resistant; furfuryl alcohol resin impregnated both acid and alkali. Heat tolerance of different varieties also have differences: carbon and graphite in a reducing atmosphere can be resistant to 2000 to 3000 DEG C, in an oxidizing atmosphere respectively in 350 and 400 degrees Celsius oxidation; impermeable graphite varieties with impregnating vary, generally by the heat-resistant phenolic or furfuryl alcohol immersed in 180 DEG C below.
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.
