Summary on Grant Application Form |
|
It is based on an invention by the applicants to reproduce the dispersive-distributive mixing achieved in large co-rotating twin screw extruders but in a very small device holding typically 10 to 100g of material. The principle of operation is based on combining two opposing flows: a single screw extruder circula flow with a twin screw extruder mixing flow. The mixing is carried out as a batch but on its completion, the single screw extruder flow is reversed and become co-current with the twin extruder flow to enable the discharging of the batch through a die. This invention provides a new opportunity to develop new products quickly, safely and cheaply. It has also other spin-offs particularly as a research tool for studying mixing and developing new, more efficient, mixing flows. In the research, we shall build a prototype of this mixer to observe and analyse dispersive mixing and develop mixing rules. We will investigate the effects design and operation parameters on dispersive and distributive mixing of polymer melts-additives and pastes-additives using image analysis of microtome sections of the extrudate. We will also carry out an analysis of the flow and develop mathematical models to underpin the experimental results.
