| 摘 要： | 利用HAAKE RV-100旋转流变仪和TR-1加压式毛管粘度计,在10-1s-1~104s-1的剪切速率范围内,测定了不同配方的三元复合体系的流变特性。流变数据处理结果认为,三元复合体系流变性可用Carreau模型来描述。研究结果显示,在所研究的条件下(碱浓度0.5%~1.5%、聚合物浓度800 mg/L~1200 mg/L、表面活性剂浓度800~1200 mg/L),三元复合体系表现出类似于聚合物溶液的流变特征,在低剪切速率和高剪切速率下,体系表现出牛顿流体特征;在中等剪切速率下,呈现剪切变稀的流变特性。随着碱、表面活性剂浓度的增加,三元复合体系的零剪切粘度下降,剪切变稀性能减弱。

| Abstract: | The theological behavior of the ASP (Alkaline-Polymer-Surfactant) system with different formulations was measured by rheomters (HAAKE RV-100 and TR-1). The results indicated that the Carrean is the beat model to describe the rheology of the ASP system. 1st Newtonian zone at low shear rate, sheaf thenning zone within medium shear rate, and 2nd Newtonian zone at high shear rate. The zero shearing viscosity decreased and shear thinning exponent increased with the increase of the concentrations of the con-centrations of alkaline and surfactant. |
