Introduction
Polyacrylamide is a type of polyelectrolyte that has been widely used in water treatment industry because of its low dosage requirement, high efficiency, and pollution-free effects.
High-molecular-weight polyacrylamide (PAM) has been widely used in chemically enhanced oil recovery processes under mild conditions. The conversion of some of the amide groups on the polyacrylamide to carboxylate groups provides greater viscosity, even when low concentrations of polymer are added to the injected water.
Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization. Reinforcing Mechanism: PAM molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.

Application
1.For flocculation, PAM can be used for recovering solid substance treating industrial effluent, domestic sewage and purifying water, assisting filtering, treatment or coal, mining, and well drilling slurry material and etc.
2.For viscosity thicker, PAM can be used for oil/gas drilling additives and water injection process in EOR(Enhanced Oil Recovery).
3.For paper mills, polyacrylamide can be used for enhance staying rate of filling material, speed size filterability and white water sedimentation in the paper and then coagulate to increase the strength of paper.
4.PAM can also be used in textile industries.
