| 中文摘要: |
| 利用聚合物加工分析软件POLYFLOW模拟密炼机中炭黑与橡胶的混合过程，采用团聚体累积粒径分布函数表征炭黑团聚体在橡胶中的分散状态，以直观反映炭黑团聚体在橡胶流场中粒径的变化情况；利用分离尺度表征混合物的分布混合性能。模拟结果表明：要得到良好的炭黑与橡胶混炼效果，提高密炼机的使用效率，必须有合理的转子转速与混炼时间。 |

| The mixing process of carbon black and rubber in an internal mixer was simulated by using polymer processing analysis software POLYFLOW.The dispersion of carbon black agglomerates in rubber was characterized by using accumulative size distribution function，which described size change of carbon black agglomerates in rubber.The mixing performance of the compound was characterized by using segregation scale.The results showed that，with optimized rotor speed and mixing time， the mixing result and efficiency were good. |
