Rheological Data of Hard-Metal Carbide Powder Compounds and their Application to Relative Viscosity Models

Popis výsledku v původním jazyce

The rheological behaviour of highly filled polymer systems used in Powder Injection Molding (PIM) technology strongly influences the final properties of the products. In this study the capillary flow data of multi-component polymer binders compounded with three various hard-metal carbide powders were employed. Over 15 mathematical models, proposed for highly filled systems were tested, calculating the maximum filler loading. Due to the complex structure of the filler (irregular shape, particle size distribution) and a multi-component character of the binder rather low applicability of these models was observed in most cases. However, a simple modification of the theoretical Frankel - Acrivos model to the systems containing hard-metal carbide powder with particles of an irregular shape and broad particle size distribution gave precise agreement between experimental data and model prediction.
