The special graphite for batteries has good chemical stability, and the specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pumps, and is widely used in petrochemical, hydrometallurgy, acid-base production, Synthetic fiber, paper making and other industrial sectors, Can save a large amount of metal materials.
It is a material for casting, casting, pressing and high-temperature metallurgy. Because of its low coefficient of thermal expansion of graphite and its resistance to rapid cooling and heating, it can be used as a mold for glassware. After graphite is used, Ferrous can be used to obtain castings with accurate size, smooth surface and high yield, which can be used without machining or slightly processing, saving a lot of metal. In the powder metallurgy process of producing cemented carbide, graphite materials are usually used to manufacture sintering dies and porcelain boats, Crystal growth crucibles, regional refining vessels, support fixtures, induction heaters, etc. are all made of high-purity graphite. In addition, graphite can also be used as vacuum melting graphite insulation plates and bases, high-temperature resistance furnace tubes, rods, plates, grid sheds, and other components.
Battery specific graphite can also prevent boiler scaling. Relevant unit tests have shown that adding a certain amount of graphite powder (about 4-5g per ton of water) to water can prevent boiler surface scaling. In addition, graphite can be coated on metal chimneys, roofs, bridges, and pipelines to prevent corrosion and rust.
Battery specific graphite can be used as pencil lead, pigment, and polishing agent. After special processing, graphite can be made into various special materials for use by relevant industrial departments.
In addition, graphite is also a polishing agent and rust inhibitor for glass and paper in light industry. It is an indispensable raw material for manufacturing pencils, ink, black paint, ink, artificial diamonds, and diamonds. It is a good energy-saving and environmentally friendly material, and has been used as a car battery in the United States. With the development of modern science, technology, and industry, the application field of graphite is constantly expanding, and it has become an important raw material for new composite materials in the high-tech field, It plays an important role in the national economy.
