Abstract

A model for investigating the melting process under a vibration force field is presented. The key parameters of this model are as follows: the rotation of the screw and heat are supplied by the vibration force field for the material phase conversion. A multidimensional vibration desk (DWZD-500) and low-density polyethylene material were used to investigate the effect of the vibration parameters on the melting process. A comparison of the derived model and experimental results revealed that increasing the vibration parameters increased the melting mass. This study will serve as the theoretical basis to optimize the parameters of vibration extruders' processing polymers. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
