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.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
