Graphite powder can be divided into various types according to particle size, but in some special industries, there are strict requirements for the particle size of graphite powder, even reaching the nano-level particle size. The following Furuite graphite editor will talk about nano-level graphite powder. Use it:
1. What is nano-graphite powder
Nano-graphite powder is a high-end graphite powder product made by special processing technology of ferroalloy. Due to its superior lubricating properties, electrical conductivity and high temperature resistance, nano-graphite powder is superior. It is more and more widely used in many industrial fields. Nano-graphite powder is a layered inorganic substance. Adding nano-graphite lubricating oil and grease has significantly improved the lubricating performance, high temperature resistance, wear resistance and wear reduction performance.
2. The role of nano-graphite powder
Lubricating oils and greases themselves are used in the field of industrial lubrication. However, when lubricating oils and greases are exposed to high temperature and high pressure, their lubricating effect will be reduced. The nano-graphite powder is used as a lubricating additive and added to the production of lubricating oil and grease. The nano-graphite powder can upgrade its lubricating performance and high temperature resistance. The nano-graphite powder is made of natural flake graphite powder with good lubricating performance. The characteristic size of nano-graphite powder is nano-scale, and it has volume effect, quantum effect, surface and interface effect. Research has shown that under the same conditions of flake crystal size, the smaller the particle size of graphite powder, the better the lubrication effect. .
The effect of nano-graphite powder in grease is better than that in lubricating oil. The nano-graphite powder can be made into nano-graphite solid lubricating dry film, which can be used on the rolling surface of heavy-duty bearings. The coating formed by nano-graphite powder can effectively It can effectively isolate the corrosive medium and at the same time play an effective lubricating role.
