Applicability of Relative Viscosity Models to Shear Flow Properties of PIM Compounds

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. Rheology of such highly filled (up to 50 vol. %) multiphase systems is necessarily a complex phenomenon # characterized by strain dependent, non-newtonian properties complicated by flow instabilities, yield and wall slip. Due to the complex structure of the filler (irregular shape, particle size distribution) and a multi-component character of the binder, the applicability of the available mathematical models vary with the powder-binder systems studied. However, the particular values of maximum loadings are in a good accordance with the predictions based on powder characteristics. Simplemodification of Frankel # Acrivos model to the systems containing unimodal hard-metal carbide powders with particles of an irregular shape and broad particle size distributions give precise agreement between experimental data and model pr
