Graphite powder is a widely used industrial material, which is obtained from high-purity graphite after crushing, grinding, and screening. The classification of graphite powder is mainly based on the particle size, ranging from 50 mesh to 30000 mesh. The larger the mesh, the finer the particle size, and the higher the price.

Graphite powder has good chemical stability. After special processing of graphite, with corrosion resistance, good thermal conductivity, low permeability, a large number of users in the production of the heat exchanger, reaction tank, condensing device, combustion tower, absorber, cooler, heater, filter, pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper, and other industrial sectors can save a lot of metal materials. So what basis do we have to buy graphite powder?
The purity of graphite powder: the carbon content of natural graphite (both purity) generally ranges from 30% to 85%, the purity of artificial graphite up to 99.9%, the higher the purity of production cost, the more expensive the price, we can not blindly pursue purity without considering the cost.
The particle size of graphite powder: at present, the foreign definition is more strict and is more used is the particle size of less than 3um powder is called ultrafine powder. Chinese scholars usually for metal and non-metallic mineral processing, generally the particle size is less than 10um powder material is called ultrafine powder. The superfine powder is usually divided into micron, submicron, and nanopowder. The particle size is greater than 1um powder is called micron powder, the particle size is in 0.1 ~ 1um powder is called submicron powder, the particle size is in 0.001 ~ 0.1um (that is, 1 ~ 100nm) powder is called nanopowder. The industry often defines the particle diameter in terms of the mesh size.
The conductivity of graphite powder, graphite powder used in the electronics industry with the lithium electricity industry not only considers the purity and particle diameter but there also is a more important factor is the electrical conductivity, as is known to all, not 100% of the conductor in nature, can according to the size to any metal or nonmetal resistance value is not the same, the smaller resistance, the fewer impurities, electrical conductivity, the better.
With the development of modern science and technology and industry, the application of graphite is still expanding, has become an important raw material of new composite materials in the high-tech field, has an important role in the national economy. , and these are our standards to buy graphite powder, of course, the use of each factor is not the same, the standard of graphite powder is not the same, we need to choose different graphite powder according to their own needs. Franli can provide different kinds of graphite powder, the quality is also very high, suitable for different industries.
