硬质聚氯乙烯低发泡挤出过程研究(2)──挤出工艺过程研究

Study on Structural Foamed R-PVC Etrusion Procession(2)──Study on the Extrusion Technology

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。

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.
