密炼机混炼胶粘度预测数学模型的建立

Mathematic Model for Predicting Viscosity of Different Rubber Mixes in Internal Mixer

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＝２ＰπＮ２Ａ；建立了单台机粘度预测模型，即μ＝ＰＮ２×１０００×（－１３８７２９＋１５１４４４／γ－２０６８１１／γ２）。此模型预测值与实测值之差的绝对值的平均值为１４１０５个门尼。

Using the regression analysis method based on the rheological theory of internal mixer mixing,the relationship of mix viscosity to dump power P,rotational speed N and filling factor ,i.e.= 2P N2A was investigated in terms of single internal mixer;and a mathematic model for predicting viscosity ofdifferentrubbermixesin single internal mixer,i.e.= P N2SX)1 000(-138 729+151 444/ -20 6811/2),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.
