First, the difference between impregnated graphite and ordinary graphite is as follows.
Impregnated graphite is a material obtained by baking at high temperatures after coating the surface of ordinary graphite with certain materials. Compared with ordinary graphite, impregnated graphite has the following differences:
1. Different nature
Ordinary graphite is a carbonaceous material formed by the close arrangement of graphite particles, which has high conductive and thermal properties. Impregnated graphite not only has these properties, but also has many properties such as high strength, corrosion resistance and high temperature resistance.
2. Different uses
Ordinary graphite is mainly used in the manufacture of electrodes, valves, bearings and other industrial products, while impregnated graphite is widely used in high temperature, high pressure and other harsh environment parts, such as aviation, aerospace, nuclear industry, vacuum technology and other fields.
3. Different performance
Due to the impregnation treatment, the structure and performance of impregnated graphite are more uniform and stable, and in the harsh environment such as high temperature and high pressure, the impregnated graphite has better performance and can withstand higher pressure and temperature.
At last, impregnated graphite is manufactured by coating ordinary graphite material on a surface and then baking it at high temperatures. Due to the relatively high cost of the manufacturing process and materials of impregnated graphite, the price of impregnated graphite is also several times or more higher than that of ordinary graphite.
Impregnated graphite is widely used in parts and equipment in harsh environments such as high temperature, high pressure, strong acid and alkali, such as aerospace, nuclear industry, chemical industry, vacuum technology and metrology technology. Impregnated graphite products mainly include impregnated graphite electrode, impregnated graphite cathode, impregnated graphite boiler tube, impregnated graphite reactor, impregnated graphite corrugated plate and so on.
