1. Product Introduction
Impregnated Copper-Graphite Ring is a high-performance sealing element made by impregnating copper alloy into a graphite matrix. This composite material not only inherits the excellent high temperature resistance, corrosion resistance and self-lubricating properties of graphite, but also enhances its electrical conductivity, thermal conductivity and mechanical strength due to the addition of copper alloy. Impregnated copper-graphite rings have been widely used in the industrial field due to their unique performance combination.
2. Materials and characteristics of impregnated copper-graphite rings
Material composition
Impregnated copper-graphite rings are mainly composed of graphite matrix and copper alloy impregnant. The graphite matrix is based on its high temperature resistance, corrosion resistance and self-lubricating properties, while the copper alloy impregnant is filled into the pores of the graphite matrix through a special impregnation process and is tightly combined with the graphite matrix to form a composite material that is both hard and elastic.
Characteristics
(1) High temperature resistance: The graphite matrix can still maintain stable performance under high temperature environment, which enables the impregnated copper-graphite ring to operate stably for a long time under high temperature conditions. At the same time, the copper alloy impregnant also has good high temperature resistance, which further enhances the high temperature resistance of the copper-impregnated graphite ring.
(2) Corrosion resistance: The graphite matrix has excellent corrosion resistance to most chemical media and can resist the erosion of various corrosive media such as acids, alkalis, and salts. The copper alloy impregnant also has certain corrosion resistance. The combination of the two enables the copper-impregnated graphite ring to maintain stable performance in corrosive media.
(3) Self-lubricity: Graphite itself has good self-lubricity, which can reduce wear and friction heat during friction. The addition of copper alloy further enhances this lubricity, making the copper-impregnated graphite ring perform well in the sealing of rotating, reciprocating and other moving parts.
(4) Excellent electrical and thermal conductivity: Copper alloy is an excellent electrical and thermal conductive material. After being impregnated into the graphite matrix, the copper-impregnated graphite ring has excellent electrical and thermal conductivity. This feature gives the copper-impregnated graphite ring a unique advantage in sealing occasions that require electrical conduction or heat dissipation.
(5) Good mechanical properties: The addition of copper alloy enhances the mechanical strength of the graphite matrix, making the copper-impregnated graphite ring have better stability and durability when subjected to mechanical stress such as pressure and shear.
