The conductivity of conductive carbon black is endowed and determined by the microstructure, so the conductivity of carbon black is also directly related to the structure.
Specifically, how to judge the conductivity through the index is as follows:
- The conductivity of carbon black is judged by the specific surface area : the larger the specific surface area, the better the conductivity ;
- The conductivity of carbon black is judged by the structure : the higher the structure, the better the conductivity ;
- The conductivity of black carbon is judged by the purity : the higher the oil absorption value, the better the conductivity;
- The conductivity of black carbon is judged by the purity +: the higher the purity, the better the conductivity.
The above kinds of judgments on the conductivity of pigment black are related to the black carbon index, and the conclusions can only be drawn through professional comparison of the conductivity of conductive carbon .
If you do not judge by the index, you can only judge by the test results. Checked, but there is no such method convenient.
