Flexible graphite carbon graphite as a sealing material for sale in sealing - quantitative tests on leakage rates from the user to the manufacturer in technology innovation and test equipment are not well resolved. Foreign attaches great importance to technology research in this area, Germany was in 1995 the development of standards, provides testing technology and equipment, requires nitrogen leakage rate is flexible graphite sheet and strip and composite panel is less than 0.1mg / m * s (DIN28091). China also We should conduct more work in this area, to improve product quality and level of use efficiency of the State in flexible graphite sealing material. Graphite series of process characteristics: Acheson graphite furnace in Qingdao graphite, graphite block factory Pingdu graphite, graphite plate graphite, graphite rod, graphite electrode firing semi-finished products is around four weeks of metallurgical coke resistance electrode material heating up and external heating, and Kastner graphitization furnace, the heating element is energized as semi-finished baking heat, so that heat mode. Graphite series resistance of the material without metallurgical coke, graphite whole process only about 10 hours, so the electricity consumption per ton less than the Acheson graphitization of about 1000 degrees. Carbon graphite, carbon industry in the North Sea Dragon (certified), graphite is provided by Carbon Co., Ltd. Weifang Sea Dragon. Weifang Sea Dragon Carbon Co., Ltd.
