Special carbon black for wires and cables plays a vital role in improving the conductivity of wires and cables. Here are the ways to improve the conductivity of wires and cables with Special carbon black for wires and cables:
1. Reduce the particle size of carbon black
The particle size of carbon black directly affects its conductivity. In theory, the smaller the particle size of carbon black, the more particles there are in a unit volume, and the denser the conductive network formed, thus improving the conductivity. Therefore, when choosing Special carbon black for wires and cables, products with smaller particle sizes should be preferred, usually between 10100nm, especially 2040nm.
2. Optimize the structure of carbon black
The structure of carbon black also has an important influence on its conductivity. DBP value (oil absorption value) is an important indicator reflecting the structure of carbon black. Carbon black with high DBP value usually has a chain branch or linear structure, which is conducive to the formation of conductive channels and improves the conductivity. Therefore, carbon black with a higher DBP value should be selected as a conductive additive for wires and cables.
3. Control the roughness of carbon black
The roughness of carbon black is also a key factor affecting its conductive properties. Appropriate roughness helps the carbon black particles to closely contact each other and form a more stable conductive network. Therefore, the roughness of carbon black should be controlled during the production process so that it fluctuates within a certain range.
4. Limit the volatile matter of carbon black
The volatile matter on the surface of carbon black is mainly composed of organic groups and oil films, which will affect the conductive properties of carbon black to a certain extent. Therefore, the volatile matter content of carbon black should be strictly controlled during the production process to keep it at a low level.
Through the comprehensive application of the above methods, the conductive properties of Special carbon black for wires and cables can be significantly improved, thereby improving the conductive properties of wires and cables, and improving the transmission efficiency and stability of wires and cables.
