Graphite is very versatile, so what is the specific use of graphite?
1, do refractories, 2, steelmaking, 3, as a conductive material, 4, for wear and lubrication materials, 5, for corrosion-resistant materials, 6, do casting, foundry, dies and high temperature metallurgical materials, 7, with in the atomic energy industry and defense industry, 8, do scaling rust-proof material
There are two new uses of graphite:
1) flexible graphite products, flexible graphite, also known as expanded graphite, is 70 years to develop a new graphite products. In 1971 US researchers successfully flexible graphite sealing material
Solve the problem of valve leakage of atomic energy, followed by Germany, Japan, France began to develop and produce. This product in addition to natural graphite has the characteristics, but also has a special flexible and elastic. Accordingly, it is an ideal sealing material, widely used in petrochemical industry, atomic energy, international market demand increased year by year.
2) the production of semi-metallic friction material since the 1970s, and the automatic clutch lining semi-metallic friction material widely used. Semi-metallic friction material is graphite and metal powder,
Steel fiber, clay powder bonded with synthetic resin. These automated liner mainly for high-speed equipment, such as aircraft, trucks and off-road vehicle brakes and clutch plates.
In recent years, asbestos has been gradually replaced by graphite. The graphite consumption depending on the field of development of the automotive industry
