Carbon and Graphite Electrode

Carbon and graphite, which are often used in mechanical engineering, can be divided into carbonaceous materials and graphite materials according to their microstructure. Carbonaceous materials are based on petroleum coke and bitumen Coke. The coal tar pitch is a binder, which is formed by kneading, compacting and heating carbonization. Graphite by source can be divided into natural graphite, artificial graphite (including special graphite) two kinds. Natural graphite also has both squamous and earthy forms. The synthetic graphite is made of carbon material and then 2,500 Shan above high temperature graphitization treatment. Special graphite is obtained by hot-pressing processing of ordinary graphite, or by other organic materials and special process. For example, the thermosetting resin by a special heat-treatment of glass carbon, the decomposition of hydrocarbons at high temperature, deposition of pyrolytic graphite, and then the formation of natural graphite in the high temperature of the high expansion of the flexible graphite, as well as carbon fiber and graphite fibers made of synthetic fiber.

Characteristics and use of diamond hard wear-resistant, commonly used as abrasive, cutting tools and exploration drills. carbonaceous materials and graphite materials have been widely used in the fields of machinery, motor, metallurgy, Chemical industry, electronics, aviation, spaceflight, rocket and atomic energy because of their excellent properties. The general man-made graphite conductive, heat-resistant, can be used to manufacture electric arc furnace and EDM mold electrode, because of lubrication wear, can be used to manufacture seals, scraping, high-temperature bearings. The impermeable graphite, which is infiltrated by thermosetting resin, is good in chemical corrosion resistance, and can be used in heat exchangers, pipes and fittings in chemical equipment. Flexible graphite is rich in elasticity, can be used to manufacture high-temperature seals, fillers, gaskets. Carbon fiber, graphite fiber strength is very high, can be used as resin, metal, ceramic, carbon matrix composite material reinforced materials. Porous graphite is capable of high-temperature, corrosion-resistant gases and liquid erosion, and can be used as high-temperature insulation material and filtration materials. High purity nuclear graphite without boron and rare earth elements can retard neutrons and be used in atomic. Because of the large thermal conductivity, the pyrolytic graphite can be used as the throat liner of the rocket nozzle, the nuclear fuel coating, and the high directional degree can be used for the gate of high-power launcher The artificial graphite can also be used as the die-casting mould for copper and aluminum and the sintering mold of electronic components; carbon bricks, carbon blocks can be used as iron blast furnace, ferroalloy large electric furnace lining; glass carbon is used to make the auxiliary surface of rotary seals and the electrodes in laser technology. As for the natural graphite, because the impurity content is big, generally only uses in the manufacture smelting crucible, the sand type coating, or as the raw material, passes through the refinement, uses in the liquid lubricant and the flexible graphite
