Effect of screw rotating speed on polymer melt temperature profiles in twin screw extruder
Source abstract
Abstract
The effect of screw rotating speed on two-dimensional temperature profiles of flowing polypropylene melt was investigated in the barrel of a counter-rotating twin screw extruder using a designed experimental apparatus and a thermocouple temperature sensing device, the experimental apparatus being connected to a high speed data logger and a computer. The flow patterns of the polymer melt in the barrel of the extruder were also revealed. The changes in melt temperature profiles with extruding time were discussed in terms of flow patterns of the polymer melt during the flow, the increase in melt temperature being closely associated with total flow length of the melt, and shear heating and heat conduction effects.
