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.
