The functions of impregnated carbon graphite mainly include reducing porosity, increasing volume density and mechanical strength, improving electrical and thermal conductivity, etc.. Through impregnation treatment, the physical and chemical properties of carbon graphite materials can be significantly improved.
Specifically, the impregnation treatment is to force the liquid impregnating agent to immerse into the pores of porous products under a certain temperature and pressure, thereby reducing the porosity of the product and improving its bulk density and mechanical strength. In addition, the impregnation treatment can also improve the electrical and thermal conductivity of carbon graphite materials.
