The stability study of La self-assembly modifier colloidals
The stability of La self-assembly modifier colloidals were investigated by the Turbiscan Lab. The results show that modifiers are unstable at the early stage and colloidal phase separation occurs. The clarification phase height increases at the top of the cell and transmitting light flux increases, backscattering light flux decreases. The sedimentation phase height increases at the bottom of the cell and backscattering light flux increases. The stability of the prepared modifier colloidals under different Ph was examined. The comparative analysis shows that the transmitting and backscattering light flux change minimum with time when Ph is between 5 and 6, that is, the stability of the modifier colloidal shows the best under this condition.
