제목 | A study to search highly effective conditions for high quality graphite through pitch impregnation process. |
초록 | An impregnation process is important to enhance the properties of synthetic graphite. Because the graphite block or electrode typically have channels as well as pores due to the evaporation of low molecular weight components during the heat treatment. These channels and pores degrade the properties of the synthetic graphite such as physical strength, electrical property, and so on, and this is why the impregnation is necessary for high quality synthetic graphite. Process conditions of temperature, pressure and time for the impregnation process are investigated. The temperature and pressure ranges were 220 - 260 ℃ at 20 ℃ increments and 1 - 40 bar at 20 bar increments, respectively. The time was experimented with 1, 2 and 4 hours respectively. The experimental evidence show that the properties of synthetic graphite can significantly enhanced with the help of impregnation process based on the petroleum impregnation pitches we synthesized. |
