Expandable graphite powder 300times superfine graphite powder for lubricant
Graphite powder
Boiling point: 4250 ℃
Dense degree: 1.6 ~ 2.2
Should be used: carburizer, smelting
Structure: high temperature resistant, conductive, thermal conductivity
Graphite powder can be divided into two main categories:
1. Natural graphite
2. Synthetic graphite
Among them, natural graphite has the following kinds:
1. Flake graphite
2. Spheroidal graphite
3. Micronized graphite
4. Expandable graphite
5. Soil graphite
Flake graphite
is a natural crystalline graphite, which is similar to fish phosphorus and belongs to hexagonal crystal system. It has layered structure. It has good properties of high temperature resistance, conductivity, heat conduction, lubrication, plasticity and acid-base resistance.
Flake graphite is a natural lubricant with a layered structure, rich in resources and cheap in price.
Natural graphite
is formed by the transformation of carbon-rich organic matter under the long-term action of high temperature and high pressure geological environment, and is the crystallization of nature. The technological characteristics of natural graphite mainly depend on its crystalline form. Minerals with different crystalline forms have different industrial values and uses. There are many kinds of natural graphite. According to the different crystalline morphology, natural graphite is divided into dense crystalline graphite, flake graphite and cryptocrystalline graphite.
