Spherical graphite regarding the uses of graphite powder
Release Date:
2020-09-14
Spherical graphite Regarding the use of graphite powder, graphite has excellent electrical conductivity and is therefore widely used. Graphite products have been widely used by many enterprises at home and abroad, gaining widespread market acclaim. Graphite is widely used in the electrical and electronic industries as electrodes, anodes for rectifiers, graphite gaskets, telephone parts, coating technology for TV picture tubes, and so on. Wear-resistant and lubricating system materials: Graphite is often used as a lubricant in the mechanical development industry. Graphite electrodes have the widest range of applications. When smelting various alloy steels and ferroalloys, powerful current can be introduced into the melting zone of the electric furnace through the working electrodes of graphite electrodes
Spherical graphite About the Use of Graphite Powder ， The use of graphite powder is very wide in our daily life, so what are its characteristics?
1. High temperature resistance: According to graphite manufacturers, graphite has a melting point of 3850 01 50 01C and a boiling point of 4250 01C. Even after ultra-high temperature arc burning, the weight loss is still very small, and it has a low thermal expansion coefficient. The strength of graphite increases with increasing temperature. At 2000 degrees Celsius, the strength of graphite doubles
2. Electrical conductivity and thermal conductivity: The electrical conductivity of graphite is one hundred times higher than that of non-metallic minerals mentioned, and its thermal conductivity is generally higher than that of metallic materials such as steel, iron, and lead. As the temperature rises, the thermal conductivity decreases at very high temperatures, and graphite will become an insulator
3. Spherical graphite Regarding the use of graphite powder, lubricity: Graphite manufacturers state that the lubrication performance of graphite depends on the size of graphite flakes. The larger the flakes, the smaller the friction coefficient, and the better the lubrication performance
4. Chemical stability: Graphite has good chemical stability at room temperature and can resist corrosion from acids, bases, and organic solvents
5. Plasticity: Graphite has good toughness and can be made into very thin sheets
6. Spherical graphite Regarding the use of graphite powder, thermal shock resistance: Graphite manufacturers outline that when used at room temperature, graphite can withstand drastic changes in temperature without damage When temperature changes, the volume of graphite does not change significantly, and no cracks are produced
