Anionic polyacrylamide is a kind of polymer compound, which is a derivative of polyacrylamide. Compared with ordinary polyacrylamide, anionic polyacrylamide has special ionic properties and application fields. The following will describe the characteristics and applications of anionic polyacrylamide.

Firstly, anionic polyacrylamide has good adsorption properties. It can be electrostatic adsorbed with positively charged particles or colloids in water to form larger precipitates or gels. This makes it widely used in the field of water treatment. In the process of sewage treatment, anionic polyacrylamide can be used as a flocculant to remove solid particles, colloids and organic substances suspended in water, and improve the clarification effect of sewage. In addition, it can be used in the fields of mineral flotation, suspension treatment in the pulp and textile industries.

Secondly, anionic polyacrylamide has excellent thickening and viscosification properties. It is often used as a thickener and clay stabilizer in oil extraction and construction projects. In the process of oil exploitation, anionic polyacrylamide can increase the adhesion between water and crude oil and improve the oil recovery. In construction projects, it can be used to stabilize and strengthen the soil, improve the soil anti-erosion ability and bearing capacity.

In addition, anionic polyacrylamide also has certain salt resistance properties. It has good water absorption performance in seawater, so it has also been applied in the fields of seawater desalination and seawater precipitation. In the process of seawater desalination, anionic polyacrylamide can remove impurities and salts in seawater by adsorption and condensation, and improve the desalination effect. In seawater precipitation, it can be used as a precipitating agent to promote the deposition of dissolved substances in seawater and purify water quality.
