Graphite is a mineral name graphite, generally produced in the metamorphic rocks, coal or carbonaceous rock (or sediment) affected by regional metamorphism or magmatic intrusions form. Graphite is an allotrope of elemental carbon, each carbon atom of the peripheral link with three other carbon atoms, carbon graphite prices were the honeycomb arrangement of a plurality of hexagons, each room has a weak van der Waals attraction . Since each carbon atom will emit an electron, those electrons can move freely, and therefore belong graphite conductor. Graphite is one of the most soft mineral, opaque and oily texture, color from black to steel gray iron, shape of crystals, flakes, scaly, striped, layered body or distribute in metamorphic rocks. Chemically inert, corrosion resistant. Our natural graphite resource superpower (2/3 of world reserves), but many foreign research on expanded graphite late than. Expanded graphite is a soft graphite factory Qingdao new carbon material, which in the 1970s by the US company Union Carbide first development application, introduced in the early 1980s in China. In addition to natural graphite expanded graphite itself, resistance to thermal, corrosion resistance, self-lubricating and other excellent performance outside, but also because of its special molding process and the special microstructure, and a soft, resilient, low stress relaxation does not have natural graphite rate. All kinds of animal used in petrochemical, power, metallurgy, machinery and other industries, static seals Pingdu graphite, and exhibit low cost, low energy consumption, long life, good effect and so on. Qingdao graphite, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd. Weifang. Weifang Sea Dragon Carbon Co., Ltd. (www.longmentanye.com) strong, credible, Shandong Weifang graphite and carbon products industry has accumulated a large number of loyal customers.
