Introduction to the principle of twin-screw plastic extruder: Firstly, twin-screw extruder has the extruder principle of single screw extruder: solid conveying, melting, pressurization, and pumping, mixed stripping and devolatilization, but it is not just that. The research on twin-screw extrusion theory started late, and coupled with its diverse types, complex screw geometries, and intricate extrusion processes, it has brought many difficulties to the research Overall, the research on twin-screw extrusion theory is still in its initial stage, which is known as' more skill than science ' The study of its extrusion process can be roughly divided into three stages:
1. The changes in the physical state of polymers during the extrusion process, the conveying principle, the truth and laws of solid melt conveying and exhaust, and the establishment of mathematical and physical models to guide the design of twin-screw extruders and the optimization of extrusion processes
2. To understand the true changes in the physical state of two or more polymers and materials during extrusion, the process of mixing morphology, structural changes, and the relationship between the final mixture and performance
3. As a twin-screw extruder, establish a model to guide the reaction process, speed, performance, screw configuration, and operating conditions during extrusion reaction molding.
