Abstract

The invention discloses a high polymer material plasticizing transportation device based on tension rheology and shear rheology for stretching and shearing materials synchronously in the high polymer material plasticizing transportation process, comprising at least one plasticizing transportation unit arranged on a same transmission shaft. All plasticizing transportation units are connected together in series and each plasticizing transportation unit comprises a feeding disc, an exhaust disc, an extrusion disc arranged between the feeding disc and the exhaust disc, and a plurality of tooth-shaped push rods arranged in a rectangular through hole of the extrusion disc and evenly distributed along a circumference direction. Full compound dynamic plasticizing transportation extruder can be combined by overlapping the plurality of plasticizing transportation units; plasticizing transportation unit, various screw extrusion units or plunger injection units can be combined into a compound dynamic plasticizing injector of various extruders or injectors.

Description

technical field [0001] The invention relates to a plasticizing and transporting device for polymer materials, in particular to a plasticizing and transporting device for polymer materials based on extensional rheology and shear rheology. Background technique [0002] At present, both extrusion and injection of polymer materials are completed by screw, and the energy used by the screw for the transportation of plastic raw materials, melting and plasticization accounts for the vast majority of the energy consumption of polymer material processing. In the screw machine, the plasticizing and transporting of materials mainly depends on the drag effect on the material when the screw rotates: solid transport is friction drag, melt transport is viscous drag, and the velocity gradient of the material is perpendicular to its flow and deformation direction. The deformation is mainly dominated by the shear stress. Therefore, it can be considered that the currently widely used screw mac...
