Abstract:

With the help of physical and analytical models of polymer melting under the impact of pure vibration force field, the expression of polymer melting rate and vibration parameters was obtained. Low-density polyethylene (LDPE) was used in the calculation, and some conclusions were obtained. Melting rate increased with the increase of vibration frequency and amplitude. However, after vibration intensity reached a limit value, melting rate would remain unchanged. In the end, a multidimensional vibration experiment was used to prove the validity of the conclusion. Calculations were in good agreement with the result of experiment. This research will serve as the basis for polymer processing and equipment design.
