Calculation of Parameters of Granular Polymer Material Plasticization Process Under Intense Shear Impact

Abstract

The characteristics of the granular polymer material plasticization process in a plasticizer shear flow are studied. A mathematical model of the process, which fully conforms to the modern concepts of the plasticization mechanism and allows determination of the key process parameters, particularly the plasticization time, under intense shear impact on the polymer granules, is proposed. This model provides the possibility of performing technological calculations even at the stage of designing mixing equipment for preparation of highly viscous polymer solutions.
