Influence of Montmorillonite's Concentration on the Thixotropy of Hydrotalcite-like Compounds/Montmorillonite Suspensions

摘要

In this paper,we found that the change of sodium montmorillonite's (MT) concentration in the magne-sium-aluminum-ferrum hydrotalcite-like compounds (Mg-Al-Fe-HTlc)/MT suspensions would greatly influence the thixotropic type of the suspensions.Specifically,the increase in the MT's concentration increases the viscosities (η) of the HTlc/MT suspensions with the same R value (the mass ratio of HTlc to MT was signed as R,e.g.,R=mHTlc/mMT),meaning that the structure strength of the HTlc/MT suspensions increases.With the variation of MT's concentration,the thixotropic type of the HTlc/MT suspensions changed accordingly,and the mechanism has been discussed in this paper.
