The conductive effect of carbon black means that carbon black can improve the conductive properties of rubber, so that it has special functions such as antistatic, anti-interference, and anti-corrosion. The conductivity of carbon black mainly depends on the following factors:
Carbon black content:
Content refers to the mass or volume of carbon black contained in a unit mass or unit volume of rubber, which reflects the proportion of carbon black in rubber. Generally speaking, the higher the content, the greater the concentration of carbon black in rubber, which increases the contact and connection between carbon black particles, forms a conductive network, and improves the conductive effect of rubber.
The resistivity of carbon black:
Resistivity refers to the resistance value of carbon black per unit length and unit cross-sectional area, which reflects the conductivity of carbon black particles themselves. Generally speaking, the lower the resistivity, the better the conductivity of the carbon black particles themselves, which reduces the resistance between the carbon black particles and improves the conductive effect of the rubber.
Form of carbon black:
Morphology refers to the shape and surface characteristics of carbon black particles, which reflect the contact mode and connection strength between carbon black particles. Generally speaking, the more regular the shape, the larger the contact area between carbon black particles, which increases the contact and connection between carbon black particles and improves the conductive effect of rubber.
