High rature viscosity measurement
Webconduct extrusion tests on HDPE/EUG blends. The step shear rate viscosity measurement mode is used. The length-diameter ratio of the die is 20:2, the shear rate is 20, 50, 100, 200 and 500s-1, and the extrusion temperature is 150 °C or 170 °C. The extrudate at 50s-1 and 500s-1 is used to measure the extrusion swell ratio. Results and Discussion WebThe resistance of a liquid to flow is called its viscosity. Viscous liquids like syrup and shampoo flow slowly. Less viscous liquids like water and gasoline flow quickly. The viscosity of a liquid usually depends on its temperature. Viscosity generally decreases as the temperature increases.
