Conductive carbon black characteristics?
【Large specific surface area】
The specific surface area is inversely proportional to the carbon black particles. When the carbon black has a larger specific surface area, there are more particles per unit volume, and it is much easier to contact each other to form a network path. Therefore, the larger the specific surface area, the higher the conductivity. good.
【Good dispersion performance】
When the appearance of carbon black particles is soft and has a high structure, it is easier to be processed and dispersed, the electrical properties/mechanical properties of the material are easier to achieve a balance, and the final product can achieve a smooth and smooth appearance.
【Surface Chemical Properties】
In the process of carbon black production, the active oxygen-containing groups formed on the surface of carbon black can generate electron migration, which will reduce the conductivity, so the pH value can be used to reflect this index, weakly alkaline or neutral carbon The black surface has few functional groups.
【Excellent electrical conductivity】
High-structure carbon black can achieve excellent electrical conductivity with a small amount of addition, and is not affected by secondary crushing.
Conductive carbon black products have greater flexibility, and can meet different conductive and shielding requirements in terms of metal coating, particle core type, particle size and particle shape.
