摘要：

The influence of single and compound dispersant on the sedimentation performance of modifiedultrafine Al（OH）3powder aqueous suspension was studied by the determination of the settlement rate and the Zeta potential.The results showed that the type and dosage of the dispersant have remarkable impacts on the dispersion stability.Using the mixture of DP-270and Sodium C16alkylbenzenesulfonate（mass ratio=1∶1）in the Al（OH）3aqueous suspension,the dispersion stability was improved effectively.As for spherical particles with electricity in a size of0.55 1.67μm,the settlement rate in aqueous solution can be calculated with a modified formula:V=V0[esp（ζn-ζ0） /ζ0]-1.
