Sedimentation equilibrium of ultrafine A1(OH)3 particles in aqueous solution

摘要：

The influence of dispersant on sedimentation performance of ultrafine Al(OH)3 aqueous suspension was studied by the determination of settlement rate and Zeta potential. And the settlement rate formula of powder particle in water solution was modified. Results showed that 0.2％ addition of DP-270 has better dispersion effect on Al(OH)3 aqueous suspension. As for spherical powder particle with electricity at size range 0.55～1.67μm, the settlement rate in aqueous solution can be calculated with modified formula: V=V0 esp（ζn-ζ0）/ζ0-1.
