摘要
以造纸污泥为研究对象,采用NXS-11型旋转黏度计在室温(23·5℃)条件下对质量浓度为55%、60%和65%的污泥进行剪切应力测试,获得不同剪切速率下对应的剪切应力和黏度值,得出造纸污泥的流变曲线,并回归出流变方程和黏度表达式。可以看出浓度为55%和65%污泥的流体类型为假塑性流体,60%污泥的流体类型为宾汉流体。
With papermaking sewage sludge as the object of study, start the the conditions of the mass concentration of 55%, 60% and 65% of the sludge shear stress test by the NXS-11 rotational viscometer at room temperature （23.5℃）, obtained different shear rates corresponding to shear stress and viscosity values, draw the paper sludge flow curve and return to the flow equation and the viscosity expression. The results show that the concentration of 55% and 65% of the sludge types of fluid for pseudoplastic fluids, 60% of the sludge type of fluid to Bingham fluid.
