Measuring, Monitoring, and Controlling Viscosity in Real Time
The increasing use of recycled materials and raw materials from various sources poses ever-greater challenges for extrusion plants. Fluctuating material qualities make it difficult to maintain consistent product quality and stable processes.
With the Visco-P inline viscometer, PROMIX offers a solution for continuously monitoring the melt directly within the production process. The system measures the actual viscosity under real processing conditions directly in the melt stream, without a bypass and without material loss.
The maintenance-free measuring module reliably homogenizes the melt and prevents clogging, deposits, or material degradation. This makes the system particularly suitable for recycled materials, filled compounds, and shear-sensitive materials.
At Fakuma, PROMIX will demonstrate the automatic control of the intrinsic viscosity (IV) value during PET extrusion. If the measured IV value falls below the specified setpoint, the system automatically controls the dosing of an IV enhancer until the desired melt quality is restored. The same principle can also be applied, for example, in PP recycling through the metered addition of suitable chain extenders.
Additional trend analyses, statistical functions, and reporting features enable comprehensive documentation of process data. User-definable thresholds automatically trigger warning messages in the event of deviations and assist the plant operator in quickly optimizing the process.
The Visco-P is compatible with all common extruder types and most thermoplastic materials and can be easily integrated into existing systems. All standard communication interfaces are available for integration into modern production environments and Industry 4.0 concepts.
