When mixing black antistatic rubber material, the structure of carbon black is easily damaged after mechanical shear, and the plasticity of the result increases, but the antistatic property (that is, the electrical conductivity) is damaged, so the mixing can reach a uniform dispersion degree, beware of overmixing.
The plasticity of the compound should be controlled at 0.4 to 0.450 sheet out type hot refining time should not be too long, and the roll distance should not be too small, for the same reasons as above.
The deeper the degree of vulcanization crosslinking, the more smooth the electrostatic path and the better the electrostatic conductivity removal effect.
