A Computer Model for Single Screw Plasticizing Extrusion


A fully predictive pc model has been developed for a single-screw plasticating extrusion. The model considers five zones of the extruder and the die, and describes a surgical procedure of the extruder-die program, making it possible to predict a mass move level of the polymer, pressure and temperature profiles along the screw channel and in the die, sturdy bed profile, and electric power consumption. Moreover, combining degree, heat range fluctuation and viscoelastic houses of the polymer happen to be estimated. The simulation parameters will be the material and rheological twin screw extrusion manufacturer properties of the polymer, the screw, hopper and die geometry, and the working conditions. Such a comprehensive method of the modeling of extrusion makes the possibility of optimizing the process, for example, from the point of view of the grade of extrusion. The model has been verified experimentally for a low-density polyethylene on a 45 mm diameter single-screw extruder.
