Impregnated graphite

Product name: Impregnated graphite

Impregnation is one of the necessary processes for products such as high-density carbon graphite products and graphite electrodes .

Impregnation is a process that forces liquid materials (asphalt, synthetic resin, low melting point metal) to penetrate into the pores of products under certain temperature and pressure. The purpose of impregnation of carbon products is to increase the volume density of products and reduce porosity and permeability, increase the mechanical strength of products and improve electrical and thermal conductivity. Commonly used antimony-impregnated graphite is an excellent solid material with high temperature resistance, wear resistance and self-lubricating properties. It can be used under high temperature of 500 ℃ , deep cooling of -253 ℃ , high speed of 2000 rpm and high pressure of 10MPa. Chemical graphite equipment generally impregnates the processed rough graphite with synthetic resin to achieve the effect of not being penetrated by reactive gases or liquids in the chemical production process .
