Graphite saggar is made must have measures to fill the gaps in the graphite, make its permeability of graphite materials Contains impregnated graphite pressed graphite Casting graphite 3 kinds Graphite saggar has excellent corrosion resistance and physical and mechanical function, can manufacture anticorrosive equipment is widely applied in chemical industry Graphite sagger anti-corrosion functional advantages are as follows: 1 appearance is not easy to scale: The affinity between graphite sagger and most media is very small, so dirt is not easy to adhere to the surface, especially used in condensation equipment and crystallization equipment 2 excellent corrosion resistance function: All kinds of carbon and graphite saggers have excellent corrosion resistance to all concentrations of phosphoric acid and hydrofluoric acid, including fluorine containing media. The highest application temperature is 350-400, that is, the temperature at which carbon and graphite saggers begin to oxidiate 3. They can withstand certain high temperature: The application temperature of imperpermeability graphite sagger depends on the type of impregnating material, such as phenolic impregnated graphite can be resistant to 170-200, if the appropriate amount of silicone impregnated graphite is increased, it can be resistant to 350; When phosphoric acid is deposited on carbon and graphite, the oxidation resistance of carbon and graphite saggers can be improved, and the operating temperature can be further improved. 4 Excellent heat conduction function Graphite saggers also have good heat conduction function, and the heat conduction function of wrong and wrong metal materials is only higher than that of metal materials, ranking first among non-metallic materials The thermal conductivity is 2 times of carbon steel and 7 times of stainless steel, so it is suitable for use in heat transfer equipment
