Product Details


The main purpose:

 

1. As a refractory material: Graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for ingots and linings of metallurgical furnaces.

2. As a conductive material: In the electrical industry, it is used for the manufacture of electrodes, brushes, carbon rods, carbon tubes, positive electrodes of mercury current collectors, graphite gaskets, telephone parts, coatings for TV picture tubes, etc.

3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the machinery industry. Lubricating oil often cannot be used under the conditions of high speed, high temperature and high pressure, while graphite wear-resistant materials can work at high sliding speed at (1) 200~2000 ℃ temperature without lubricating oil. Many equipment for conveying corrosive media widely use graphite materials to make piston cups, sealing rings and bearings. They do not need to add lubricating oil during operation. Graphite milk is also a good lubricant for many metal processing (wire drawing, tube drawing).

4. Graphite has good chemical stability. Specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability, and is widely used in the production of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters , Pump equipment. It is widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, which can save a lot of metal materials.

5. For casting, sand casting, compression molding and high-temperature metallurgical materials: Due to the small thermal expansion coefficient of graphite and the ability to withstand changes in rapid cooling and rapid heating, it can be used as a mold for glassware. After using graphite, ferrous metals can obtain castings with accurate size and smooth surface yield. High, can be used without machining or a little machining, thus saving a lot of metal. In the production of powder metallurgy processes such as cemented carbide, graphite materials are usually used to make porcelain boats for compression molding and sintering. Single crystal silicon crystal growth crucibles, regional refining vessels, support fixtures, induction heaters, etc. are all processed with high-purity graphite. In addition, graphite can also be used as graphite heat insulation board and base for vacuum smelting, high temperature resistance furnace tube, rod, plate, grid and other components.

6. Used in atomic energy industry and national defense industry: Graphite has a good neutron moderator and is used in atomic reactors. Uranium-graphite reactor is a kind of atomic reactor with more applications. As a deceleration material in a power atomic energy reactor, it should have high melting point, stability and corrosion resistance, and graphite can fully meet the above requirements. As the graphite used in atomic reactors, the purity requirements are very high, and the impurity content should not exceed several tens of PPM. In particular, the boron content should be less than 0.5PPM. Graphite is also used in the defense industry to make nozzles for solid fuel rockets, nose cones for missiles, parts for aerospace equipment, thermal insulation and radiation protection materials.

7. Graphite can also prevent scaling of boilers. Tests of relevant units show that adding a certain amount of graphite powder to water (about 4-5 grams per ton of water) can prevent scaling on the surface of boilers. In addition, graphite coating on metal chimneys, roofs, bridges and pipes can prevent corrosion and rust.

8. Graphite can be used as pencil lead, pigment and polishing agent. After special processing of graphite, various special materials can be made for relevant industrial sectors.
In addition, graphite is also a polishing agent and rust inhibitor for glass and paper in the light industry, and is an indispensable raw material for the manufacture of pencils, inks, black paint, inks, synthetic diamonds and diamonds. It is a good energy-saving and environmentally friendly material, and the United States has used it as a car battery. With the development of modern science, technology and industry, the application field of graphite is still expanding, 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.
