The technological properties of high purity graphite bearing:

1, high temperature resistant: graphite is known to most of the high temperature resistant material. Its melting point was 3850 and 50, and its boiling point was 4250.. It is high at 7000 DEG C under 10S arc, the minimum loss of graphite, graphite by weight loss 0.8%. Thus, the high temperature of graphite is very prominent..

2, a special thermal shock resistance, thermal shock resistance of Ishi Sumiku good, namely when the sudden temperature changes, the thermal expansion coefficient is small, and has good thermal stability, in the sharp temperature quench heat change, no crack.

3, thermal conductivity and electrical conductivity: graphite has good thermal and electrical conductor. Compared with the general material, its thermal conductivity is very high. 4 times higher than that of stainless steel, 2 times higher than carbon steel, non metal than the average 100 times higher.

4, lubrication, the lubrication performance of the graphite similar to molybdenum disulfide, friction coefficient is less than 0.1. Their lubrication properties vary with the scale size, larger scale, the smaller the coefficient of friction is, lubrication, the better.

5, chemical stability at room temperature: graphite has good chemical stability, acid resistance, alkali resistance, corrosion resistance to organic solvents.
