Extrusion process and link of twin screw extruder granulator
Dec 13, 2018

The twin screw extruder granulator has the extrusion principle of a single-screw extruder when it is used, and its solid transport is melted during operation, pressurized and pumped, mixed stripping and devolatilization, but not simply . The research on the twin-screw extrusion theory started late, coupled with its many types, complicated screw geometry and complicated extrusion process, which brought many difficulties to the research. From the whole, the research on twin-screw extrusion theory is still In the initial stage, this is what is called "more skill than science."
Extrusion process and link of twin screw extruder granulator
1. The change of the state of the polymer during the extrusion process, the principle of transporting the solid phase of the solid melt and the law of the exhaust, establish a mathematical physical model to guide the design and extrusion process of the twin-screw extruder Optimization.
2. To understand the true state of the physical state of the two or more polymers and materials during the extrusion process, the mixing morphology, the process of structural changes, and the relationship between the final mixture and the properties.
3. As a twin-screw extruder, the internal relationship between the reaction process, speed, performance and screw configuration and operating conditions during extrusion reaction molding is established to guide the reaction molding extrusion.
