Influence of Different Dispersants on Dispersion Stabilities of TiO_2 Powders in Water

Effect of several dispersants (PEG,PMAA,MN)on aqueous suspension of submicron TiO 2 powder is focused in the study.The experimental results show that the TiO 2 aqueous suspension with MN dispersant has many advantages such as low viscosity,little dosage,no agglomeration,width pH et al.So the system with MN dispersant excels that with PEG or PMAA.
