| Résumé : |
Melt flow index - State-of-the-art quality control systems for production require precise and real time measurement of control parameters such as the MFI. Such measurements lead to optimized process control, product quality, and reduced consumption of resources. |
| Note de contenu : |
- Conventional MFI measurement
- Melt flow index in real time
- Melting the polymer in an online lab
- Calibration
- Measurement of volume rate and pressure
- FIGURES : 1. Traditional MFI and MVI measurements in the lab : Details are established in the standard ISO 133 - 2. Melt flow index measurement device : The OPS from OCS is configured for online measurements - MVR data for steady state and a product transition between 4 and 5 : The green line represents the high frequency online data of a OP5 rheometer, the yellow line represents the low frequency in lab test results - 4. Online system components : a) Film line with camera and FTIR analysis, b) Offline-container (left side), which supplies the film line during a shutdown and container for collecting lab samples, c) Pellet analyzer, for measuring contaminations, color, throughput and size and shape distribution, d) main rack and control system for the pellet transport system - 5. Die block of the OPS system |
