The main purpose of polyacrylamide polyacrylamide washing is an important water-soluble polymer flocculant, and both flocculation, thickening, shear resistance, drop resistance valuable properties, such as dispersion. These properties vary derivative ions and different emphases. Thus in oil, mineral, coal, metallurgy, chemicals, paper, textiles, sugar, medicine, environmental protection, building materials, agricultural production and other departments have a wide range of use. Rheology refers to substances in the external force flow deformation characteristics. From the relationship between the apparent viscosity and the shear rate of the anti-temperature and salt polyacrylamide see, under moderate shear rate conditions, an aqueous solution of polyacrylamide often exhibit pseudoplastic, i.e., its apparent viscosity with increasing shear rate large reduction. Also increases with the shear rate of the dilatant fluid, typically present in high solids content (> 50%) of the dispersion. Has been reported that hydrophobic associating polymer solution in the high shear region also showed some dilatant behavior. From the relationship between the apparent viscosity and time to see zwitterionic polyacrylamide, another rheological properties of polyacrylamide (especially hydrophobic association polyacrylamide) solution is thixotropic, namely, the continuing role of shear stress in the polyacrylamide, the apparent viscosity decreases when the shear force is removed, over time, the apparent viscosity was gradually restored.
