1) flocculation: polyacrylamide can make suspended substances through electric neutralization, bridging adsorption, flocculation.
2) bonding: through mechanical, physical and chemical effects, the bonding effect.
3) resistance reduction: polyacrylamide can effectively reduce the friction resistance of fluid, adding trace polyacrylamide in water can reduce resistance by 50-80%.
4) thickening: polyacrylamide has thickening effect in neutral and acid conditions, when th...
