The application of reinforced gaskets to enhance the effect of mechanical sealing——Expanded graphite is a new type of mechanical sealing material, which has sufficient elasticity, softness, self-lubrication and impermeability, but its low strength is its weakness . For this reason, a gasket with expanded graphite compounded on both surfaces of the original various gaskets has appeared, which greatly improves the sealing performance of the mechanical seal. In order to facilitate transportation, use and installation, a metal mesh or a thin plate washed into fish scales and a gasket compounded with expanded graphite on both sides have achieved satisfactory sealing effects. ◊It can be used not only in petrochemical industry, but also in automobiles The cylinder gasket of the engine has been successful.　　220.html,
