概述了国内外炭黑及橡胶填料标准的差异以及炭黑细粉含量对混炼工艺和胶料性能的影响,指出气力输送过程中影响炭黑破碎率的主要因素。分析了国内外细粉含量对胶料加工性能、机械性能影响的研究情况,指出了炭黑细粉含量对炼胶质量确实存在一定影响。橡胶制品质量稳定性及炭黑细粉含量的研究对提升我国橡胶制品的质量具有重要意义,国内研究者应加大对炭黑细粉含量的研究,提升产品竞争力。
The differences between the standards of carbon black and rubber filler at home and abroad as well as the influence of the carbon black content on the properties of the compounding process and the rubber compound are summarized. The main factors influencing the carbon black fragmentation rate are pointed out. The research on the influence of the content of fine powder on the processing performance and mechanical properties of the compound was analyzed. It was pointed out that the content of carbon black does have some influence on the quality of the rubber compound. The research on the quality stability of rubber products and the content of carbon black powder is of great significance to improve the quality of rubber products in China. Domestic researchers should increase the research on the content of carbon black fine powder to enhance the competitiveness of products.
