Graphite rod nut characteristics:
1. Jebsen graphite nut high temperature resistance: it 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 loss of graphite nut under 3000 ℃ ultra-high temperature arc for 10s, and the loss of graphite nut is 0.08% by weight. It can be seen that the high temperature resistance of graphite nut is very prominent.
2. Special thermal shock resistance of graphite nut: Graphite nut 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 of graphite nuts: Graphite nuts have 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 of graphite nut: the lubricity of graphite nut 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 of graphite nut: Graphite nut has good chemical stability at normal temperature, and can resist acid, alkali and organic solvent corrosion.
