Abstract

A suspension consists of surface-modified ultrafine calcium carbonate, di-n-octylphthalate and calcium oxide was used as the research system in this paper. The transforming from antithixotropy to thixotropy, the formation, stability and strength of the thixotropic structure, andthe influence of the free fatty acid on the transforming were studiedin detail. The results revealed that the transforming depends on the storage time. As the storage time extended, the suspension transfers from antithixotropy to thixotropy and stable thixotropy was obtained after stored 24 h. At the same time, the strength of flocculated structure stablized gradually. If the free fatty acid exists, the suspension will transfer to antithixotropy. And a physical model of the thixotropic structure is introduced, which is connected with the dispersion-stability properties of the suspension.
