The effects of extrusion technology and procession parameters-the screw speed, cylinder temperature profile, and die-head temperature on the structural foamed R-PVC extrusion stability were studied. The special rheological properties of the R-PVC melt containing gas were investigated. 研究了挤出工艺过程及参数&螺杆转速、挤出温度、机头温度等对硬质PVC低发泡挤出过程稳定性的影响,同时研究了含气PVC熔体的特殊流变性能。
