How to judge the conductivity of conductive carbon black?
Jun 25, 2022
The electrical conductivity of conductive carbon black is endowed and determined by the microstructure of carbon black, so the electrical conductivity of carbon black is also directly related to the structure of carbon black. How to judge the conductivity of carbon black specifically, here are a few practical methods for everyone.
1. Judging the conductivity of carbon black by the specific surface area of conductive carbon black: the larger the specific surface area of carbon black, the better the conductivity;
2. Judging the conductivity of carbon black by the structure of conductive carbon black: the higher the structure of carbon black, the better the conductivity;
3. Judging the conductivity of carbon black by the purity of conductive carbon black: the higher the oil absorption value of carbon black, the better the conductivity;
4. Judging the conductivity of carbon black by the purity of conductive carbon black: the higher the purity of carbon black, the better the conductivity.
The above-mentioned judgments about the conductivity of carbon black are related to the indicators of carbon black, and the conclusions can only be drawn through professional comparison of the conductivity of conductive carbon black. Checked, but there is no such method convenient.
