摘要：

The work presents the results of experimental studies of plasticized poly(vinyl chloride) (PVC) extruded by a single-screw extruder with a modified feed section. The variable factors were the feed opening width, the feed pocket depth in the extruder barrel, and the rotational speed of the screw. The following parameters were studied: extrudate temperature T-w (degrees C), screw torque M (Nm), polymer mass flow rate G (kg/h), unit consumption of energy supplied to the extruder E-jc (J/g), and extrusion process energy efficiency kappa (%). It was found that the increase in the depth of the pocket and the decrease in the width of the feed opening influence the extrusion process in a positive way.
