| Carbon black carbon particles and the structural is together as chain or grapes shape the degree to say. By condensed body size, shape and each condensed bodies of particle number consists of condensing body composition of carbon black called high structure carbon black. The common values mean structural oil absorption, oil absorption is, the higher carbon structural, easy to create space, and network access not easily damaged. High structure carbon black fine grain, mesh chain accumulation closely, the unit quality grain much, is advantageous in polymer chain conductive structure in which formed in numerous silica varieties with acetylene black is the best. The particle size distribution wide carbon than distribution narrow carbon particles can give more conductive polymers, and statistical method to explain the phenomenon. Particle size distribution wide black, a few large diameter particles need huge number, diameter smaller particle compensation, the same average particle size distribution wide distribution of carbon black carbon than more narrow particle total. | |
