Internal and external factors affecting the lubricity of Low price graphite powder from China

1. Internal factors affecting the lubricity of Low price graphite powder from China

1) The influence of particle size, the larger the particle size, the smaller the friction coefficient, and the smaller the particle size, the larger the bearing capacity;

2) Influence of crystallinity: flake graphite and flake graphite have complete crystallinity and superior lubricity; Earthy graphite has poor crystallinity and lubricity.

3) Due to the influence of impurities, the wear rate of graphite with ash content of less than 1% is much smaller than that of natural graphite with ash content of 2%, and the grinding effect is significantly reduced;

4) Due to the influence of particle shape, graphite with a large ratio of the area of the base surface to the area of the prism has a small abrasiveness. The more flat the graphite is, the smaller the specific wear of the lubricated material is.

2. External factors affecting the lubricity of Low price graphite powder from China

1) The temperature characteristic data of Low price graphite powder from China show that graphite is a good lubricant from room temperature to 538 ℃, and fails because of the rapid oxidation of graphite above 538 ℃. If phosphorus oxide or expanded material is added, the high temperature of 700 ℃ can be used;

2) The friction and wear of graphite powder are controlled by the environment atmosphere, mainly because the wear rate of graphite decreases with the increase of water vapor pressure;

3) Under the influence of speed and load, the friction coefficient of Low price graphite powder from China decreases with the increase of coincidence within the range of bearing capacity.

As a lubricant, Low price graphite powder from China has the advantages of good high temperature resistance, good lubricity, good chemical stability, non-toxic and low price. Other characteristics of Low price graphite powder from China also have many uses in other industrial fields such as conduction, heat conduction and sealing.
