Abstract |
Extrusion is one of the major methods for processing polymeric materials and the thermal homogeneity of the process output is a major concern for manufacture of high quality extruded products. Therefore, accurate process thermal monitoring and control are important for product quality control. However, most industrial extruders use single point thermocouples for the temperature monitoring/control although their measurements are highly affected by the barrel metal wall temperature. Currently, no industrially established thermal profile measurement technique is available. In this work, a highly instrumented single screw extruder has been used to study the effect of temperature on HDPE lumps in the extrusion process. Three different molecular weight grades of high density polyethylene(HDPE) were extruded at a range of conditions. Three geometries of extruder screws were used at several set temperatures and screw rotation speeds. The extruder was equipped with real-time quantification of energy consumption; thermal dynamics of the process were examined using thermocouple grid sensors at the entrance to the die. Results showed that HDPE lumps had a significant effect on surface. Extruder screw geometry, set extrusion temperature and screw rotation speed were also found to have a direct effect on HDPE lumps and granules . These results highlight that the screw geometry and melt temperature affected on HDPE lumps and granules. |
