Internal and external factors affecting the lubricity of customized graphite powder from China manufacturer

1、 Internal factors affecting the lubricity of customized graphite powder from China manufacturer.

1） The larger the particle size is, the smaller the friction coefficient is, and the smaller the particle size is, the greater the bearing capacity is;

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

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

4）The influence of particle shape, the larger the ratio of the area of the base surface to the area of the prisms, the smaller the abrasiveness of the graphite. The more flat the graphite is, the smaller the specific wear of the lubricated material is.

2、External factors affecting the lubricity of customized graphite powder from China manufacturer

1） The influence of service temperature and the temperature characteristic data of graphite 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） Under the influence of environmental atmosphere, the friction and wear of customized graphite powder from China manufacturer are dominated by environmental atmosphere, mainly because the wear rate of graphite decreases with the increase of vapor pressure;

3） Under the influence of speed and load, the friction coefficient of customized graphite powder from China manufacturer decreases with the increase of load.

Customized graphite powder from China manufacturer as a lubricant has the advantages of good high temperature resistance, good lubricity, good chemical stability, non-toxic and low price. Some other characteristics of graphite powder are also used in other industrial fields such as electric conduction, heat conduction and sealing.
