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 is a kind of mineral powder, mainly composed of carbon, soft, black gray; Greasy can pollute the paper. The hardness is 1 ~ 2, along the vertical direction with the increase of impurities the hardness can be increased to 3 ~ 5. The specific gravity is 1.9 ~ 2.3. Under the condition of oxygen isolation, its melting point is above 3000℃, and it is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, insoluble in water, dilute acid, dilute alkali, and organic solvents.
The graphite powder produced by Franli has a very good performance. Franli graphite has good high-temperature resistance, The melting point of graphite is 3850±50℃, and the boiling point is 4250℃. Even after ultra-high temperature arc burning, the weight loss is very small, and the thermal expansion coefficient is very small. The strength of graphite increases with the increase in temperature. At 2000℃, the strength of graphite increases twice.
Franli graphite also has ultra-high electrical and thermal conductivity, The conductivity of graphite is 100 times higher than that of ordinary non-metallic minerals. Thermal conductivity exceeds steel, iron, lead, and other metal materials. Thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite becomes an insulating body. Franli graphite also has good lubricity, chemical stability, plasticity, and thermal shock resistance.
Franli supplies graphite to different countries around the world, in different fields such as refractory, Because our graphite has high-temperature resistance, high strength properties, in the metallurgical industry is mainly used to manufacture graphite crucible, in steelmaking graphite is commonly used as a protective agent of ingot, metallurgy furnace lining. Of course, our graphite can also be used as electrode material, In the electrical industry, it is used as the cathode of the electrode, brush, carbon rod, carbon tube and mercury positive current device, graphite gasket, telephone parts, coating of the TV picture tube, etc. The most commonly used is as lubricating material， Graphite powder is often used as a lubricant in the machinery industry. The lubricating oil can not be used under the conditions of high speed, high temperature, and high pressure, while graphite wear-resistant material can work without lubricating oil at the high sliding speed at the temperature of (I) 200 ~ 2000 ℃. Many types of equipment transporting corrosive media are widely made of graphite materials, such as piston cups, sealing rings, and bearings. They do not need to add lubricating oil when they operate. Graphite emulsion is also a good lubricant for many metal processing (wire drawing and pipe drawing).
The graphite provided by franli to countries all over the world has been widely praised and is also used in various industries. People from all walks of life are welcome to buy it.
