Graphite milk factory | Sea Dragon Carbon | graphite provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) is specialized in the "graphite" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Chin. Graphite and carbon products have excellent performance, used widely, productivity and efficiency was a rapid growth trend. In 2011, the development of graphite and carbon products industry rapidly carbon graphite, enterprises in the industry are higher costs of management and control capabilities, strong profitability. National Bureau of Statistics data show that in 2011, China's carbon and graphite products industry realized an industrial output value of 167.564 billion yuan; sales revenue 167.765 billion yuan, an increase of 40.58%; total profit of 10.959 billion yuan, an increase of 50.87%. With the application of the continuous promotion of graphite and carbon products industry competition has become increasingly fierce. Graphite crystals with a typical layer structure of carbon atoms arranged in a hexagonal mesh-like layer, the carbon atoms on the surface network node with respect to the center of the upper and lower adjacent layers of the grid. Repeat for 2 layered graphite 2H polytype, is a hexagonal graphite factory in Qingdao, which is commonly referred to graphite; if repeated three layered graphite compared 3R polytype, trigonal system graphite milk, but in Natural graphite structure alone can not be separated. In graphite crystal structure, the coordination number of the inner layers of carbon atoms is 3, with a covalent bond metal, spacing 0.142nm graphite, is connected to the molecular bond between the layers, and pitch is 0.340nm, such a special crystal structure and chemical bonding of graphite has some special process performance.
