1. Flocculation: PAM can make suspended substances act as flocculants by neutralizing electricity and bridging adsorption.
2. Adhesiveness: It can play an adhesive role through mechanical, physical and chemical action.
3. Resistance reduction: PAM can effectively reduce the friction resistance of fluid, adding trace PAM in water can reduce resistance by 50-80%.
4. Thickening property: PAM can be thickened under neutral and acid conditions, and PAM with PH value above 10 is easy to hydrolyze. Thickening will be more obvious when the structure is semi-reticulate.
