Abstract
The aim of this paper is to develop a new extruder
control system for recycled materials which has ability to
automatically maintain constant a polymer melt viscosity of
mixed recycled polymers during extrusion, regardless of
variations in the Melt Flow Index (MFI) of recycled mixed grade
high density polyethylene (HDPE) feedstock. A closed-loop
controller is developed to automatically regulate screw speed and
barrel temperature profile to achieve constant viscosity and
enable consistent processing of variable grade recycled HDPE
materials. The experimental results of real time viscosity
measurement and control using a 38mm single screw extruder
with different recycled HDPEs with widely different MFIs are
reported in this work
