Embodiment
[0021] Such as Figure 1~5 As shown, the plasticizing transportation equipment has a barrel 1 with a cylindrical inner cavity, a first plasticizing sheet 2 and a second plasticizing sheet 3 placed in the barrel, and four plasticizing sheets for regulating the fluid flow separated by the plasticizing sheet. The cam ring 4 for the flow between the two spaces and the left baffle plate 5 and the right baffle plate 6 on both sides of the barrel 1. In this plasticizing transport equipment, the pull handle 7 is fixedly connected with the cam ring 4, the number of plasticizing sheets is two, and the cylindrical cavity in the barrel 1 is divided into four spaces, and each plasticizing sheet has a groove 9 cooperates with the cam ring 4, and the groove 9 that cooperates with the cam ring 4 is the flow port between the spaces separated by the first plasticizing sheet 2 and the second plasticizing sheet 3, and the size of the flow port is determined by the cam ring. The gap between the c...

The invention discloses a polymer material plasticizing device based on extensional rheology, which includes a barrel with a cylindrical inner cavity, several plasticizing sheets placed in the barrel, and is used to regulate the flow of fluid when separated by the plasticizing sheets. The cam ring for the flow between the opened spaces and the baffle plate on both sides of the barrel and, in this plasticizing transportation equipment, the number of plasticizing sheets is at least two, which divides the cylindrical cavity in the barrel into several spaces, Each plasticizing sheet has a groove to match with the cam ring. The groove matching with the cam ring is the circulation port between the spaces separated by the plasticizing sheet. The axis rotates and the rotation speed of each plasticizing sheet is not exactly the same. The shape of the cam ring corresponds to the rotation speed of the plasticizing sheet, so as to ensure that the material flows and reverses between the spaces separated by the plasticizing sheet along the rotation direction of the plasticizing sheet. The invention has the characteristics of short material thermomechanical course, low energy consumption, wide adaptability, small volume and the like.
Description
technical field [0001] The invention relates to a polymer material plasticizing processing method and equipment, in particular to polymer material plasticizing equipment based on extensional rheology. Background technique [0002] The molding and processing of polymer materials is a high-energy-consuming process. At present, screw machines, such as screw extruders and screw injection machines, are widely used. All must go through the basic and common process of conveying and melting plasticization. The energy used in this process accounts for the vast majority of the energy consumption of polymer materials processing. In the screw machine, the plasticization of the material is mainly due to the drag effect on the material when the screw rotates. The solid transport is frictional drag, and the melt transport is viscous drag. The velocity gradient of the material is perpendicular to its flow and deformation direction. This flow and deformation are mainly affected by Shear str...
