以3种不同产地的膨润土为研究对象,研究了膨润土悬浮体的流变性。研究结果表明,3种试样制成的膨润土悬浮体均表现为负触变性,试样A、B膨润土悬浮体流变曲线的触变环面积较大,流变性表现明显;剪切应力与膨润土悬浮体中小于10μm的颗粒含量呈正相关。
Taking bentonite from three different places as the research object, the rheological properties of bentonite suspension were studied. The results show that all the bentonite suspensions made from three kinds of samples show negative thixotropy. The thixotropic ring area of the rheological curves of the bentonite suspensions is larger and the rheological properties are obvious. The shear stress and bentonite The content of particles less than 10μm in suspension was positively correlated.
