What is graphite powder? The hardness of graphite powder is 1~2, and along the vertical direction, the hardness can increase to 3~5 with increased impurities. The specific gravity is 1.9~2.3. Under the condition of oxygen isolation, its melting point is above 3000 ℃, one of the most temperature-resistant minerals. At room temperature, the chemical properties of graphite powder are relatively stable. It is insoluble in water, dilute acid, alkali, and an organic solvent; The material has high-temperature resistance and conductivity and can be used as refractory, conductive, and wear-resistant lubricating material. Graphite powder is a substance with a very sensitive chemical reaction. Its resistivity will change in different environments; its resistance value will change, but one thing will not change. Graphite powder is one of a good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in the insulating object, it will also be energized like a thin wire. However, there is no accurate number for the resistance value because the thickness of graphite powder is different; the resistance of graphite powder will be different for different materials and environments.
Use of graphite powder Graphite has good chemical stability The specially processed graphite, with corrosion resistance characteristics, good thermal conductivity, and low permeability is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pump equipment. It is widely used in the petrochemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, paper making, and other industrial sectors, which can save a lot of metal materials For casting, sanding, die casting, and high-temperature metallurgical materials. Due to graphite's small thermal expansion coefficient and its ability to withstand rapid changes in cooling and heating, it can be used as a mold for glassware. After using graphite, ferrous metal can be used for casting with accurate dimensions, a high yield of smooth surface, and can be used without processing or a little processing, thus saving a lot of metal. Graphite materials are usually used to make ceramic boats for die casting and sintering for cemented carbide and other powder metallurgy processes. The crystal growth crucible of single crystal silicon, regional refining container, m bracket fixture, induction heater, etc., are all made of high-purity graphite; in addition, graphite can also be used as graphite insulation plate and base for vacuum smelting, high-temperature resistance furnace tube, rod, plate, grid, and other components.
Conductive principle of graphite powder General rubber is insulated. If conductive materials are needed, conductive materials should be added. Graphite powder has superior conductivity and lubrication demoulding properties. Graphite powder is processed into graphite powder with excellent lubrication and conductivity. The higher the purity of graphite powder, the better the conductivity. Many special rubber products factories need conductive rubber, so can graphite powder be added to rubber to conduct electricity? The answer is yes, but there is also a question: what is the proportion of graphite powder in rubber? The proportion used by some enterprises is no more than 30% on wear-resistant rubber products, such as automobile tires, etc., and the proportion of special rubber plants is 100% so that the conductivity can be conducted. The basic principle of conductivity is that the conductive body cannot be interrupted, just like a wire; if it is interrupted, it will not be energized. The conductive graphite powder in the conductive rubber is the conductor. If the graphite powder is separated by insulating rubber, it will not conduct electricity. Therefore, the conductive effect may not be good if the proportion of graphite powder is less.
Price of graphite powder Graphite powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of graphite powder. A large amount of large amount will be lower. The graphite powder price can be found on our company's official website.
