The graphite particles

use

1, refractory materials: in the metallurgical industry with graphite crucible, smelting non-ferrous, special steel and other precious metals, as furnace lining magnesia-carbon brick; In addition, it is also used as insulation agent, protective slag and ladle covering agent for casting ingot in steelmaking.

2. Conductive materials: graphite can be used as electrode, brush, rod, carbon tube, kinescope tube and vacuum tube coating in the electrical industry.

3, wear-resistant materials and lubricants: wear-resistant and lubricating materials can be used in the mechanical industry, such as graphite can be within the temperature range of -200-2000℃, sliding at a speed of 100m/s, without lubricating oil. Graphite lubricants include oil agent, water agent, powder colloidal graphite, graphite grease, graphite packing and so on.

4, sealing materials: with flexible or expanded graphite for centrifugal shaft, water turbine, gas turbine and transmission of corrosive media equipment piston ring gasket, sealing ring, automobile cylinder pad, etc.

5, corrosion resistant materials: graphite can be made of utensils, pipes and equipment, such as heat exchanger, reaction tank, pickling tank, etc., because of its resistance to all kinds of gas, liquid corrosion, widely used in petroleum, chemical, hydrometallurgy and other departments.

6, heat insulation, high temperature resistance, radiation protection materials: nuclear reactor neutron moderator and anti-atomic radiation shell and rocket nozzle, missile nose cone, aerospace equipment parts, heat insulation materials, anti-ray materials, etc..

7. Brake antifriction material: in the brake pads of motor vehicles, graphite is used as antifriction agent to protect the pair and reduce the noise.

8. Other aspects: mold paint, pencil, battery, electrode, graphite bomb that causes short circuit of transmission line, anti-ray material, etc.
