Working principle of Extrusion Screw Barrel

On the whole, although the current theory of extruder screw is very mature, there is still room for improvement. From its extrusion process research, the extruder screw is divided into three parts
1. During the extrusion process, the change law of the physical state of the polymer, the transportation principle of the solid melt, the stage and law of the transportation and discharge of the solid melt are established. Use mathematical and physical models to guide the planning of the extruder screw and the optimization of the extrusion process
2. It is necessary to find out the true state change, mixing shape, structure change process of two or more polymers and materials during the extrusion process, as well as the relationship between the mixture and its function
3. As an extruder screw, establish the internal relationship between the reaction process, speed and function, screw configuration and operating conditions in the extrusion reaction molding process to guide the reaction molding extrusion.
