The graphite material and parts are already widely used in all kinds of industries for almost 50years,as the many good properties,such as :electricity conducting,corrosion resistance and good thermal conductivity,it is widely used for electrode,electro-chemical power,carbon brush on the motor and the gasket etc. However,the mechanical properties of graphite material is weak,easy to break and crash,limit the range of use. The graphite material impregnated with phenolic resin can improve the mechanical properties. The phenolic resin has several good properties such as high thermal stability, structural integrity etc,and making it as one of the binders of graphite is a good way to reduce the opening rate and improve the mechanical properties. Now the graphite impregnated phenolic resin is one of the most…
Carbon fiber and resin, metal, ceramics and other matrix composite, made of carbon fiber composite materials. Fiber reinforced material has been the focus of people's attention. Since the advent of glass fiber and organic resin composite, carbon fiber, ceramic fiber and boron fiber reinforced composite materials have been successfully developed, and the performance of the composite materials has been improved. Let us know about the carbon fiber composite material with no special features. Carbon fiber is a kind of special fiber which is made up of carbon. The carbon content of carbon fiber is different, and it is generally more than 90%. Carbon fiber has the characteristics of carbon materials, such as high temperature, resistance, electric conduction, heat conduction and…
The graphite gasket is made of the flexible graphite,also called expandable graphite,it’s one of the new type carbon materials since 1960s,and it first come from the patent of Union Carbine Co USA. After that,with the development of petroleum chemical industry and nuclear power industry,the need for sealing material is also more strict,and the flexible graphite sealing material replace the asbestos material. The flexible graphite has the similar properties with the natural graphite on the structure.and it has many good properties such as high thermal resistance,corrosion resistance,resilience, radiation resistance,high purity etc. The purity of the flexible graphite has a big influence to the sealing property,the Sulpher in the graphite will separate out and make the surface corrosion of the metal,and weak…
