Study on the Rheological Properties of Partially Hydrolyzed Polyacrylamide Saline Solution

摘要

The rheological measurements in terms of steady and oscillatory are reported for the saline solutions of partially hydrolyzed polyacrylamide (HPAM) with a concentration range from 400mg/L to 5000mg/L by using RS150 Haake rheometer. Also, the effect of temperature on the behavior of the HPAM solutions is discussed The HPAM solution showed shear-thinning behavior. The linear viscoelastic range for HPAM solutions according to these tests was about 2.0 Pa. HPAM saline solutions showed elastic behavior and its viscoelastic behavior depends strongly on the temperature.
