摘　　要：应用多普勒激光测速计测量同向旋转双螺杆挤出机捏合区域的速度分布。在90r/min的转速下 ,测量了两螺杆捏合区中推力区和阻力区熔体的轴向速度和法向速度。Velocity distributionin in kneading zone of co rotating twin screw extruder is measured by Laser Doppler Anemometry.Axial and normal velocity of polymer melt among reverse conveying region and forward conveying region in kneading zone of co rotating twin screw extruder are also measured at the screw speed of 90 r/min.

关 键 词：捏合区 速度分布 双螺杆挤出机 塑料 成型
