Detailed Product Description: | Pressure installation under the Act applies to a smaller diameter graphite bearing temperature range and little change in the situation. When using this method of installation to ensure that the bearings and bearing sleeve absolutely straight and pressure stability. Loose installation method This installation method is only applicable to the next through the thin wall bearing load conditions. When installing a graphite sleeve bearings allow rotation in, in order to prevent transmission around, you can also use a key to fix. Graphite due to its special structure, which has the following special properties: 1) High temperature resistance: the melting point of graphite is 3850 ± 50 ℃, boiling point of 4250 ℃, even after ultra high temperature electric arc burning, weight loss is very small, the thermal expansion coefficient is also very 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 graphite flake graphite depends on the size of the graphite gasket, the larger flake graphite products, graphite friction coefficient is smaller, the better lubricating properties. 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 packing 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. Graphene battery, graphite, carbon industry is provided by the North Sea Dragon Sea Dragon Carbon Co., Ltd. Weifang. Carbon Co., Ltd. Weifang Sea Dragon (www.longmentanye.com) strong, credible, Shandong Weifang graphite and carbon products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the industry in the North Sea Dragon carbon into the brilliant and you work for a better future! |
