Graphite sheet is widely used in metallurgy, chemical industry, electrochemistry and other industries, the reason is that it has good conductivity, high temperature resistance, acid and alkali corrosion resistance, easy processing and other characteristics. Let's talk about its performance.
1. The anisotropy of graphite sheets. It is well known that graphite belongs to a hexagonal structure, and the carbon atom spacing in the plane layer is significantly different from the carbon atom spacing between the upper and lower layers. Therefore, there is obvious anisotropy in thermal conductivity, thermal conductivity and thermal expansion coefficient.
2. Excellent corrosion resistance of graphite sheet and flexible graphite. Maintain good chemical stability for general chemical solvents, petroleum products, esters, steam, hectare reflux medium, etc.
3.Irradiation resistance of graphite sheet, flexible graphite material has good radiation resistance.
4. The density, compression and rebound of graphite sheet, and the obvious difference between flexible graphite and ordinary graphite is that it has good flexibility and resilience. The relationship between density and specific pressure increases as the specific pressure increases. When the density reaches 1.8g/cm 3 or more, the density changes little with the increase of specific pressure.
