Rheological Behavior of Mixture of Carbonyl Iron Powder (CIP) and High Density Polyethylene (HDPE)


Article Preview

Rheological study has been performed experimentally by using melt flow index (MFI) tester on a mixture of CI (Carbonyl Iron) powder and HDPE (High-Density Polyethylene) polymer. The rheological properties such as volume flow rate (cm3/s), shear strain rate (s-1) and viscosity (Pa.s) are investigated for varying conditions of temperature and weight (pressure). This also includes experimental determination of viscosity dependence over parameters like temperature, shear strain rate and CI powder loading by weight added in HDPE. For this experimental conditions selected are temperatures 4480K-5230K in steps of 250K, weights in MFI tester (ultimately converted to shear strain rate) 0.325, 1.20, 2.16, 3.80, 5.00Kg and carbonyl iron powder loading in binder HDPE (by weight) 80%-92% in steps of 6%. A constitutive equation for viscosity is formulated which considers all factors affecting viscosity with the maximum percentage error of about 4% between experimental value and value predicted by the formulated equation is obtained.
