摘　　要：本研究以大量可视化实验结论为基础 ,提出熔融子区的概念 ,并定义了啮合同向双螺杆挤出过程中 1 0种典型的熔融子区。这不仅有利于人们对复杂的双螺杆挤出过程聚合物熔融的认识与理解 。Based on lots of experimental results with visualization twinscrew extruder,the conception of submelting zone is concluded.Ten typical submelting zones of corotating twinscrew extrusion are defined,which not only does help to understand and master the complex melting process,but also provides an feasible way for optimizing of polymer melting.
