Technological characteristics of Jebsen graphite material:
1. Jebsen graphite high temperature resistance: graphite is one of the most high temperature resistant materials known at present. Its melting point is 3850 ℃± 50 ℃, and its boiling point is 4250 ℃. It has the lowest graphite loss of 0.8% by weight under the ultra-high temperature arc of 7000 ℃ for 10s. It can be seen that the high temperature resistance of graphite is very prominent.
2. Special thermal shock resistance: graphite has good thermal shock resistance, that is, when the temperature changes suddenly, the coefficient of thermal expansion is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.
3. Thermal conductivity and conductivity: graphite has good thermal conductivity and conductivity. Compared with ordinary materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel and 100 times higher than general non-metal.
4. Lubricity: the lubricity of graphite is similar to molybdenum disulfide, and the friction coefficient is less than 0.1. Its lubricity varies with the scale size. The larger the scale, the smaller the friction coefficient, and the better the lubricity.
5. Chemical stability: graphite rod has good chemical stability at normal temperature, and can resist acid, alkali and organic solvent corrosion.
Graphite is a crystal of carbon and a non-metallic material. It is silvery gray, soft and metallic. Mohs hardness is 1 ~ 2, specific gravity is 2.2 ~ 2.3, and its bulk density is generally 1.5 ~ 1.8.
