Detailed Product Description: | By conventional production process of producing graphite carbon blocks using ordinary carbon production process can be made porous carbon and porous graphite block, the difference is added to colloidal graphite pore forming agent in the formulation, the pore-forming agent decomposed or volatilized during firing and graphitization stomata. Commonly used porogen sodium chloride graphite products, sodium fluoride, sawdust, etc., controlling the addition amount of a pore-forming agent and a pore forming agent is added in particle size, can substantially control porous carbon and porous graphite porosity and pore size. Due to its special structure of graphite graphite manufacturer, and has the following special properties: 1) High temperature resistance: graphite melting point of 3850 ± 50 ℃, boiling point 4250 ℃, even after ultra-high temperature arc burning, weight loss is very small thermal expansion coefficient is small. Graphite strength with temperature increase and strengthen, at 2000 ℃, the graphite strength doubled. 2) electrical conductivity, thermal conductivity: the conductivity of graphite higher than the average non-metallic minerals a hundred times. Thermal conductivity than steel, iron, lead, metal materials. Thermal conductivity decreases with increasing temperature, even at very high temperatures, the graphite into a thermal insulator. Graphite graphite can be conductive because each carbon atom with other carbon atoms is formed only three covalent bonds, each carbon atom remain a free electron to transfer charge. 3) lubrication: lubrication performance depends on the size of the graphite flake graphite, the flake greater the smaller the coefficient of friction, lubrication, the better the performance. 4) Chemical stability: graphite at room temperature have a good chemical stability to acid, alkali and corrosion resistance to organic solvents. 5) plasticity: graphite, graphite toughness, can be crushed into very thin slices. 6) thermal shock resistance: graphite used at room temperature can withstand dramatic changes in temperature will not destroy lives, when sudden changes in temperature, little change in the volume of graphite, will not crack. Sea Dragon graphite _ _ Carbon graphite provided by Carbon Co., Ltd. Weifang Sea Dragon. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) Shandong Weifang, graphite and carbon products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
