摘要
在带有在线取样和在线显微观察系统的全程透明视窗单螺杆挤出机上 ,采用普通三段式螺杆和分离型螺杆 ,对LDPE和LLDPE等物料进行了挤出实验。对实验过程中的固体床结构与变形、固体粒子的变形现象和变形机理进行了描述和分析 ,针对固体粒子的粒间运动与变形现象 ,提出了固体粒子粒间变形三个阶段的概念。
The experiments are carried out on the single screw extruder with the on line samples and the on line visual microscopical system.Using conventional three stage screw and barrier type screw for LDPE and LLDPE,The phenomena about solid-bed structure and deformation,solid particle deformation,and their deformational mechanisms are described and analysed.In the light of the conditions of the particulate motion and deformation between the solid particles,the concept of three different stages of the solid particle deformation has also been advanced.
