China's production of natural graphite products, most of the primary processing products. These carbon graphite primary processing products manufacturer, are faced with the problem of overcapacity graphite, while excess capacity and suppress prices. Prior to 2011, the largest output of natural graphite flake graphite commodity prices gradually ascending, until 2011 reached 6,700 yuan / ton. Then its price began falling, as the current, graphite powder prices higher bit has fallen more than 50%. Our natural graphite resource superpower (2/3 of world reserves), but many foreign research on expanded graphite late than. Expanded graphite is a soft new carbon material, which is 70 years from the first US company Union Carbide to develop applications, 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 roughness than graphite, but also because of its special molding process and the special microstructure, and have no natural graphite soft, resilient, low The stress relaxation rate. All kinds of animal used in petrochemical, power, metallurgy, machinery and other industries, static seals, and exhibit low cost Qingdao graphite factory, low energy consumption, long life, good effect and so on.
