Uses of Expanded Graphite Sheets

Expanded Graphite Sheets are generally used as refractory materials. Graphite crucibles made of graphite Sheets can be used as protective agents for steel ingots and magnesium carbon bricks for lining smelting furnaces.
In many mechanical equipment, graphite Sheets can be used as wear-resistant and lubricating materials. The use of such materials does not require or reduces the use of lubricating oil to a certain extent. In addition to the above functions, graphite Sheets can also be used as sealing materials: flexible graphite is used as piston rings and sealing rings for centrifugal pumps, steam turbines and equipment to transport corrosive media.
When using corrosion-resistant materials, graphite Sheets also show good application advantages. The use of graphite Sheets as vessels, pipes and equipment can resist the corrosion of various corrosive gases and liquids, and is widely used in petroleum, chemical industry, hydrometallurgy and other departments.
Then, graphite Sheets can be used as heat preservation, high temperature resistance and radiation protection materials: graphite Sheets can be used as neutron moderators for nuclear reactors, as well as rocket nozzles, missile nose cones, aerospace equipment components, heat preservation materials, radiation protection materials, etc.
In the current building system, polystyrene is a common wall insulation material. Graphite, foaming agent and other additives are added to the polystyrene raw material. The graphite is wrapped in the inner wall of the bubble to form a fireproof layer. The heat reflection effect of graphite makes the flame retardant function of the graphite board better than that of the general insulation board.
