Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand
The better conductivity is graphitized carbon, the higher the degree of graphitization, the better the conductivity. In general, the conductivity of graphite is better than that of black carbon (both of which are of high purity, if not of high purity).
With graphite powder, the specific explanation is some chemical principle not elaborate
Suggested carbon blackBecause of the good lubricity of graphite, the addition of graphite will increase the lubricity of the concreteIn addition, compared with the same amount of graphite and carbon black, the volume of carbon black is larger, the surface area is also large, the contact area increases, and the conductive network is easier to formFirst of all, I hope I can help you
But the conductive carbon black in plastic system can achieve better quality with less graphite is because in polymer systems, factors of conducting conductivity in addition to the conductive powder itself, but also with the distribution of conductive particles in the polymer related. The same quality of the carbon black and graphite carbon black, due to a smaller proportion, occupy a large volume fraction of the polymer, is conducive to the formation of conductive network, which was better than the effect of conductive filler graphite.But in the high aggregation state, the conductivity of graphite aggregate is much better than that of carbon black. The good conductive electrode material is made of graphite instead of carbon black.
