以工业聚酯终缩聚圆盘反应器开发应用为研究背景，分别考察了介质粘性、弹性、盘径和盘间距对圆盘反应器流型及宏观混合时间的影响。实验结果表明：高粘、弹性、高剪切和小的盘间距有利于混合；釜径增大，混合效率降低。 Based on the development and application of industrial polyester final disc reactor, the effects of medium viscosity, elasticity, disc diameter and disc spacing on the flow pattern and macroscopic mixing time of disc reactor were investigated respectively. The experimental results show that: high viscosity, flexibility, high shear and small disk space are conducive to mixing; reactor diameter increases, the mixing efficiency decreases.
