Graphite has the following special properties due to its special structure:
1, high temperature resistance
The melting point of graphite is 3850±50℃, even after ultra-high temperature arc burning, the weight loss is very small, the coefficient of thermal expansion is very small. The graphite strength increases with the increase of temperature. At 2000℃, the graphite strength increases twice.
2, electrical and thermal conductivity
Graphite is a hundred times more conductive than ordinary non-metallic minerals. Thermal conductivity of steel, iron, lead and other metal materials. The thermal conductivity decreases with increasing temperature, even at extremely high temperatures, graphite becomes adiabatic. Graphite conducts electricity because each carbon atom in graphite forms only three covalent bonds with other carbon atoms, and each carbon atom still retains one free electron to transfer charge.
The lubrication performance of graphite depends on the size of graphite flake, the larger the flake, the smaller the friction coefficient, the better the lubrication performance.
4, chemical stability
Graphite has good chemical stability at room temperature and can withstand acid, alkali and organic solvent corrosion.
Characteristics of graphite products:
1, graphite products have good adsorption.
The hollow structure of carbon makes carbon have good adsorption, so carbon is often used as adsorption data, used for adsorption of water, odor, etc.
2, Graphite products have good thermal conductivity, fast heat transfer, uniform heating and fuel saving.
With graphite made of baking pans, POTS and other heating fast, and the food is heated evenly, cooked from the inside out, heating time is short, not only pure taste, and can lock the original nutrition of food.
3, graphite products have chemical stability.
Graphite has good chemical stability at room temperature, and is not corroded by any strong acid, strong alkali and organic solvent. Therefore, graphite products even if long-term use loss is very little, just scrub clean as new and the same.
