polyacrylamide (PAM) is a kind of linear polymer. It is one of the most widely used water-soluble polymer compounds. Polyacrylamide and its derivatives can be used as effective flocculants, thickeners, paper reinforcers and liquid reducing agents. Resistors are widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textile, construction and other industrial sectors.

1. Flocculation: PAM enables flocculation of suspended substances through electric neutralization, bridging and adsorption.
2, adhesion: through mechanical, physical, chemical role, play the role of adhesion.
3. Drag reduction: PAM can effectively reduce the friction resistance of the fluid, adding a small amount of PAM in the water can reduce resistance by 50-80%.
4. Thickening: PAM has thickening under neutral and acid conditions. When pH is above 10, PAM is easy to hydrolyze. Thickening will be more obvious when half mesh is present.
