| 中文摘要: |
| 依据密炼机流变学理论，运用回归分析方法，从单台密炼机的角度，研究了混炼胶的粘度μ与排胶功率P、转速N和填充因数γ之间的关系，即μ= 2P/πN2A；建立了单台机粘度预测模型，即μ= P/N2×1 000 ×(-138 729 +151 444/γ1/2-20 681.1/γ2)。此模型预测值与实测值之差的绝对值的平均值为1.410 5个门尼，且预测结果与按每种胶料所建模型的预测值非常接近。 |

| Using the regression analysis method based on the rheological theory of internal mixer mixing，the relationship of mix viscosity μ to dump power P，rotational speed N and filling factor γ，i.e.μ= 2P/πN2A was investigated in terms of single internal mixer；and a mathematic model for predicting viscosity of different rubber mixes in single internal mixer，i.e.μ= P/N2×1 000 ×(-138 729 +151 444/γ1/2-20 681.1/γ2)，was established.The average absolute difference between the predictive value from the model and the measured value was 1.410 5 Mooney unit，and the predictive values from this model were very close to those from the models established for individual rubber mixes. |
