摘要：The effects of additives [N(CH2CH2OH)(3), (NaPO3)(n)(n=10 similar to 20), (NH4)(2)CO3] on rheological properties of TiO2/water dispersions were studied through measurements of shear viscosity, yield stress and thixotropic loops, The results show that TiO2/water dispersions exhibit the best disperse property, low viscosity without yield stress when the mass fraction of N(CH2CH2OH)(3) is 0. 1%; but (NaPO3)(n)(n=10 similar to 20) beheves the time dependence as dispersant for TiO2/water dispersions, as flocculation agent in TiO2 industry, the concentration of (NH4)(2)CO3 has effects on the rheological properties of TiO2/water dispersions.
