説明

There are two opposite theories about the second peak in the voltage-time curve occurs when carbon black mixed in the internal mixer. The one is regarded as the dispersion process already completed, and the other is only the incorporation process almost proceeded, so the dispersion process further proceeds. We focused on the results of SBR-carbon system that the BIT is much affected by the addition of zinc oxide. As the results of this investigation, it was found that the latter theory is reasonable, even if in the case of the long BIT that the dispersion seems to be completed. Increasing the water supply temperature to mixer, the BIT was reduced and the dispersion became to be inferior. By addition of magnesium oxide or calcium hydroxide, the BIT is reduced but the dispersion became not to be superior. Whereas by addition of zinc oxide, it was found that we could reduce the BIT at low temperature and also highly improve the dispersion.
