Progress in Research on Flexible Graphite Metal Composite Structure Sealing Gasket
Among the new carbon materials,flexible graphite is widely used because of its high weather resistance,radiation resistance,low expansion and good self-lubrication,and is known as the"king of contemporary sealing".However,due to the shortcomings of flexible graphite such as porosity,oil absorption and low strength,it is easy to collapse and fall apart in service,which seriously restricts the application and promotion of this material.Flexible graphite composites have the excellent properties of both graphite and metal,and can form multi-channel seals,and have gradually become the preferred materials for sealing materials under extreme conditions in petroleum,chemical,automotive,nuclear power and other fields.In this paper,the structure and composition of composite gaskets are analyzed,and the application prospect and development trend of graphite seals in petrochemical,nuclear power and other fields are prospected.
