Product advantages 1, high-strength graphite, easy processing, high temperature resistant, uniform particles, stable resistance, etc 2, in coarse graphite: easy processing, high temperature resistant, uniform particles, stable resistance, low price, no specification limits, etc 3, graphite electrode, easy processing, high temperature resistant, uniform particles, stable resistance, low price, no specification limits, etc Character: 1) high temperature resistant type: graphite melting point is ***0 + *0 °C, boiling point is ***0 °C, even by the ultra high temperature arc ignition, weight loss is small, thermal expansion coefficient is small. Graphite with temperature increase and strengthen the intensity, at ***0 °C, the intensity of graphite double. 2) conductive, thermal conductivity, the conductivity of graphite nonmetalliferous ore is one hundred times higher than normal. Thermal conductivity than steel, iron, lead and other metal materials. Coefficient of thermal conductivity decreases with temperature rise, and even at high temperatures, graphite into insulator. 3) lubricity, lubrication performance depends on the size of the graphite flake graphite, flake, the greater the friction coefficient is smaller, the better the performance of lubrication. 4) chemical stability: graphite at room temperature with good chemical stability, acid, alkali and corrosion resistance to organic solvent. 5) plasticity: graphite good toughness, can be in very thin slices. 6) thermal shock resistance: graphite when used at room temperature can withstand the severe changes of temperature without damage, temperature mutations, graphite volume change is not big, won't produce crack. Natural graphite has many excellent properties and wide application of the national economy departments, especially in metallurgy, machinery, electrical appliances, has been widely used in chemical industry.
