摘要

设计了一种新的动态混合器，用于混合两种不相容的聚合物熔体。采用正交试验法，选择了动态混合器混合区的三个主要设计参数（孔圈数（N）、每圈孔数（M）和孔直径（d3）），研究了它们对压降（Δp）和偏析尺度（S）的影响。还研究了流量和转速的影响。此外，还将混合效果与螺杆和开槽螺杆混合机进行了比较。结果表明，影响S和S∙Δp的最显著因素是N。Δp和S均随流量的增加而增加，随转速的增加而减少。与螺杆和开槽螺杆混合机相比，动态混合机具有更好的混合效果和更短的长度。

Tuning of Mixing Zone Parameters in a Dynamic Mixer and Performance Comparison with Screw-based Mixers

A new dynamic mixer has been designed for the mixing of two incompatible polymer melts. Three main design parameters (number of circles of holes (N), number of holes (M) per circle, and diameter of the holes (d3)) for the mixing zone of the dynamic mixer were selected to study their influences on the pressure drop (Δp) and the segregation scale (S) using Orthogonal tests. The influences of flow rate and rotational speed were also investigated. In addition, the mixing effect was compared with that of screw and slotted-screw mixers. The results showed that the most significant factor influencing S and S∙Δp is N. Both Δp and S increased with increasing flow rate, and decreased with increasing rotational speed. Compared to the screw and slotted-screw mixers, the dynamic mixer had a better mixing effect and shorter length.
