Graphite powder is a chemical substance with very smart exothermic reaction. In different natural environment, its resistance changes, that is to say, its resistance will change, but it is not easy to change at all. Graphite powder is a very good non-metallic conductive chemical substance. If you make sure that the graphite powder is continuous in the insulating layer, you can plug in electricity like this Xianxia, but There is no exact value of the standard value. Due to the different sizes of graphite powder, the resistance of graphite powder used in different raw materials and natural environment will be different.
Graphite powder is soft, gray black, greasy and can pollute the environment. The strength is 1-2, and the strength can be increased to 3-5 along the vertical direction with the increase of residue. The ratio is 1.9-2.3. Under the standard of CO2 barrier, its melting point is about 3500 ℃, which is the fourth most high temperature resistant mineral. At room temperature, the physical properties of graphite powder are stable, insoluble in water, dilute acid, dilute alkali and solvent; the raw materials have heat-resistant conductivity, which can be used as fire-resistant and thermal insulation materials, conductive raw materials, wear-resistant and moistening raw materials.
Because of its unique structure, high-purity graphite has unique characteristics:

1. Heat resistant type: the melting point of high-purity graphite is 3850 ± 60 ℃, and the melting point is 4250 ℃. Even after electric arc cauterization by pasteurization, the damage of net weight is not big and the coefficient of linear expansion is not big. The compressive strength of high-purity graphite increases with the increase of temperature. At 3000 ℃, the compressive strength of high-purity graphite increases several times.

2. Conductivity and heat transfer: the conductivity of high-purity graphite is 1000 times higher than that of ordinary mining enterprises. Heat transfer super tapping, iron, lead and other metal composite materials. The heat transfer coefficient decreases with the increase of temperature, and even at very high temperature, high-purity graphite becomes a heat transfer body.

3. Wettability: the wettability of high-purity graphite lies in the scale size of high-purity graphite. The larger the scale, the smaller the friction resistance and the higher the wettability.

4. Organic chemical reliability: high-purity graphite has excellent organic chemical reliability at room temperature, and can withstand acid, alkali and solvent erosion.

5. Ductility: the high-purity graphite has good ductility and can be used for thick plates with too thin age.

6. Thermal shock resistance: high-purity graphite shall withstand the strong change of temperature without damage when it is applied at normal temperature. When the temperature changes suddenly, the volume change of high-purity graphite is not large, which is not easy to cause cracks.
