Real-time polymer melt viscosity monitoring via torque and power analysis
A novel method for real-time polymer melt viscosity assessment using torque and power monitoring, offering potential for immediate feedback on process conditions and material properties without apparatus modification.
Overview
This innovative solution enables real-time monitoring of polymer melt viscosity through the analysis of torque and power draw during the mixing and injection processes, specifically for PET materials. By correlating power draw with molecular weight and viscosity changes, this method provides immediate feedback on process conditions, allowing manufacturers to make informed decisions without modifying existing equipment.
Technical specifications
Key features include:
- Utilization of existing mixer and injector apparatus to monitor power draw, reflecting changes in material properties
- Correlation of torque measurements with molecular weight and viscosity, offering insights into polymer quality
- Capability to detect reductions in molecular weight, aiding in the prevention of defects
- Potential for further exploration of the relationship between polymer degradation and failure modes using advanced analytical techniques
Technology readiness level
This technology is currently at TRL 4, indicating that it has been validated in a laboratory setting. Future work includes mapping power draw to material properties using advanced rheology and chemical analysis techniques, with supervision from experts at the University of Edinburgh.
