| Abstract: | The capability of the dispersion of cobalt blue in weak solvent was studied.The influence of dispersant(type & dosage),pH value,and other dispersion parameters on the stability of cobalt blue dispersion system was tested which shows good stability and excellent dispersion performance with diethylamide glycol ether the weak solvent,complex formulation(M(KH550)∶M(KH560)∶M(A-842)=1∶1∶2) the dispersant and 7 the pH value.The characteristics of dispersion system were evaluated through sedimentation experiment and measurement of article size distribution.The most steady dispersion system was formed through high speed shearing force and the size of cobalt blue in this system is about 300nm. |
