Anionic polyacrylamide is a polymer material commonly abbreviated as APAM. It is a water-soluble polymer, which is formed by copolymerization of acrylamide monomer and acrylic monomer. Because of its negative charge, it is called anionic polyacrylamide.
Anionic polyacrylamide has many excellent properties, such as high water absorption, high viscosity, high viscosity and high molecular weight. These properties make anionic polyacrylamide widely used in many fields. Especially in the field of water treatment, anionic polyacrylamide is an important flocculant and precipitator, which can remove impurities and suspended matter in water. At the same time, anionic polyacrylamide can be used for soil conservation and prevention of soil erosion.
Anionic polyacrylamide also has important applications in petroleum exploration and production. It can be used to improve formation conditions and improve exploration efficiency. During oil recovery, anionic polyacrylamide can be used to thicken and reduce water content in Wells to improve oil recovery rates.
In addition, anionic polyacrylamide can also be used in paper, printing and dyeing, leather manufacturing and medicine and other fields. In conclusion, anionic polyacrylamide is an important polymer material with wide application prospects. With the continuous development of technology, the application range of anionic polyacrylamide will continue to expand, and become an important material to promote social development.
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
