Manufacturer of graphite powder

Graphite powder is used in industry

Graphite powder has good chemical stability. The specially processed graphite powder is characterized by corrosion resistance, good thermal conductivity and low permeability. It is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorbers, coolers, heaters, filters and pumps. Widely used in petrochemical industry, wet metallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.

For casting, aluminum casting, molding and high temperature metallurgical materials: due to the small thermal expansion coefficient of graphite, and ability to the change of thermal shock, can be used as glass mold, after using graphite black metal casting dimension precision, smooth surface high yield, without processing or slightly processing can use, thus saving a large amount of metal. The production of cemented carbide and other powder metallurgy processes, usually made from graphite materials die and sintering porcelain boats. The crystal growth crucible of monocrystalline silicon, regional refining vessel, bracket clamping device and induction heater are all made of high purity graphite. In addition, graphite can be used as graphite heat insulation board and base for vacuum smelting, high temperature resistance furnace tube, rod, plate, lattice shed and other components.

Graphite also prevents the boiler from scaling, and unit tests have shown that adding a certain amount of graphite powder (about 4 to 5 grams per ton of water) to water prevents the boiler from scaling. In addition, graphite can be anticorrosive and rust-proof on metal chimneys, roofs, Bridges and pipelines.

Graphite can be used as pencil lead, paint, polish. After special processing, graphite powder can be made into various special materials for the relevant industrial departments.

In addition, graphite is a polishing agent and antirust agent for glass and paper in the light industry. It is an indispensable raw material for making pencils, ink, black lacquer, ink and artificial diamonds and diamonds. It is a good energy-saving and environment-friendly material, which has been used as a car battery in the United States. With the development of modern science and technology and industry, the application field of graphite has been continuously expanded, and it has become an important raw material for new composite materials in the high-tech field and plays an important role in the national economy.

Graphite powder on national defense

Used in the atomic and defense industries: graphite powder has good neutron moderator for atomic reactor, uranium - graphite reactor is a kind of nuclear reactor. The deceleration material in a power reactor shall have the properties of high melting point, stability and corrosion resistance. Graphite powder can meet the above requirements. Graphite, used as an atomic reactor, has high purity requirements and should contain no more than a few parts per million of impurities. In particular, the boron content should be less than 0.5PPM. Graphite powder is also used in the defense industry to make nozzles for solid fuel rockets, nose cones for missiles, components for space navigation equipment, insulation and radiation protection materials.
