1.
Polyacrylamide has flocculation: PAM can make county floats through the effects of electrical neutralization, bridge adsorption, and flocculation.
2. Adhesion: It plays an adhesive role through mechanical, physical and chemical effects.
3.
Polyacrylamide has thickening properties: under neutral and acidic conditions, PAM has a thickening effect. When the pH value is greater than 10, PAM is easily hydrolyzed. The thickening is more pronounced when the structure is semi-reticular
4. Drag reduction: PAM can effectively reduce the frictional resistance of the fluid. Adding a small amount of PAM in water can reduce the resistance by 50-80%.
