Accuracy of viscosity measurement using rotation viscometer
In the present work the effect of these parameters was measured and quantified in model fluids at room temperature with wide range of viscosity and the movement of the spindle and shaft were recorded by a camera. Considering some factors such as the type of combination between rotor and viscometer, angle between spindle and shaft, rotating speed, side movement during testing it was indicated that bigger side movement will introduce larger error and the instable side movement was the main effect to generate error, especially in low viscosity fluid, whereas the angle variation between spindle and shaft during testing affected the viscosity hardly. The articulated combination between rotor and viscometer benefited to reduce side movement significantly in high viscosity fluid, whereas it had less influence in low viscosity liquids. Therefore strongly side movements should be avoided during the test especially in low viscosity tests. High temperature measurements were performed with several groups of TiO2 containing slags in the CaO-SiO2-TiO2 and CaO-SiO2-TiO2-Na2O-Al2O3 systems. The viscosity-temperature relationships of these TiO2 containing slags have been given out in the present work as well. The chemical composition effects on viscosity were discussed such as basicity, TiO2 content, Na2O content and Al2O3 content. Additionally the mechanisms of how the viscosity is influenced in the homogeneous state and in the heterogeneous state with precipitated solid oxides.
