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 studie
d through measurements of shear viscosity, yield stress and thixotropic loo
ps, The results show that TiO2/water dispersions exhibit the best disperse
property, low viscosity without yield stress when the mass fraction of N(CH
2CH2OH)(3) is 0. 1%; but (NaPO3)(n)(n=10 similar to 20) beheves the time de
pendence as dispersant for TiO2/water dispersions, as flocculation agent in
TiO2 industry, the concentration of (NH4)(2)CO3 has effects on the rheolog
ical properties of TiO2/water dispersions.
