Erosion of Polymer Pellets during Blending in a Twin-Screw Extruder

摘要

The behavior of Newtonian droplet deformation and breakup has been well established through a fundamental study by Taylor and other researchers (such as Grace and Bentley and Leal).It is well known that polymeric drops are usually highly non-Newtonian fluids.Their behavior under even a simple shear flow may not follow the prediction by theories for Newtonian fluids.The mechanism of polymer drop deformation and breakup has been intensively studied to understand the development of morphology of polymer blends during blending,such as in twin-screw extruders (TSEs).
