| Résumé : |
Mixing and screw extrusion - Tightly intermeshing, co-rotating twin-screw extruders are commonly employed for tasks requiring good mixing. The modular structure of both barrel and screw makes it possible to optimize the extruder configuration for a given task. Increasing demands on polymers have resulted in the development of more sophisticated mixing elements. In the framework of this investigation we looked at the pressure-throughput behaviour of mixing elements in a conveying, reconveying and conveying-reconveying configuration. furthermore, the local residence time distribution within those elements was investigated. We developed physical-mathematical models to describe the pressure-throughput behaviour observed in the experimental investigations. |
