What is Impact of Feed Opening Width and Position on PVC Extrusion Process Effectiveness about?
The influence of the feed opening axis width and position in relation to the plasticizing system axis on the effectiveness of the extrusion process of poly(vinyl) chloride has been studied. The research was conducted on the extrusion line for profiles with the extruder of the screw diameter 25 mm and L/D ratio = 25. In the extruder, the extruder head was mounted with a die of a rectangular cross-section shape for extruding a sheet of a defined width and thickness. The extruder was adapted for mounting five feed segments in the feed zone of the plasticizing unit; the segments differed from one another in terms of their feed opening width, the values of which were 0.6 D, 0.7 D, 0.8 D, 0.9 D and 1.0 D, respectively, whereas the values of the longitudinal axis shift of the opening relative to the longitudinal axis of the plasticizing unit were 0.2 D, 0.15 D, 0.10 D, 0.05 D and 0.0 D, respectively, which corresponded to 5 mm, 3.75 mm, 2.5 mm, 1.25 mm and 0 mm, respectively. The effectiveness of the polyvinyl chloride extrusion process was determined by dependences of extrudate temperature, extruder screw torque, polymer mass flow rate, power supplied to the extruder and conveyed by the
