摘要 提出了一种单螺杆挤出机，由带有沟槽进料区（螺旋沟槽）的机筒、沟槽熔融区（轴向或螺旋沟槽）和带有混合和剪切元件的屏障螺杆组成。与具有平滑熔融区的挤出机相比，在质量吞吐量、压力建立、熔体温度、熔体均匀性、进料区冷却、加工壁滑移聚合物、磨料磨损、停留时间、总体效率和经济性方面实现了显着的工艺改进。阐述了新型挤出机的加工原理。实验结果证实了理论预测。 3 年来，该系统已被证明在 100 多台挤出吹塑机中非常有价值。
Abstract A single-screw-extruder is presented, consisting of a barrel with grooved feed zone (helical grooves), a grooved melting zone (axial or helical grooves) and a barrier-screw with mixing and shearing elements. Compared with extruders with a smooth melting zone, significant process improvements are achieved regarding mass throughput, pressure build up, melt temperature, melt homogeneity, feed-zone cooling, processing wall-slipping polymers, abrasive wear, residence time, total degree of efficiency and economy. The processing principles of the new extruder are explained. Experimental results confirm the theoretical predictions. The system has proven to be very worthwile in more than 100 extrusion blow molding machines since 3 years.
