Cationic polyacrylamide is an important polymer material with high cation and molecular weight. It is widely used in water treatment, paper making and oilfield development. At present, the synthesis methods of cationic polyacrylamide mainly include free radical polymerization, ion polymerization and modified polymerization. Among them, free radical polymerization is a common method, by introducing free radical initiator and crosslinking agent, control reaction conditions and material composition, can prepare high quality cationic polyacrylamide materials.
The application research of cationic polyacrylamide is mainly concentrated in water treatment, paper making and oilfield development. In water treatment, cationic polyacrylamide is widely used in coagulation, flocculation and filtration processes, can effectively remove suspended matter and pollutants in water, improve the cleanliness and transparency of water.
In the paper industry, cationic polyacrylamide can be used as coagulant and flocculant of pulp coloring, reduce impurities and suspended matter in the pulp, improve the quality and transparency of paper. In oilfield development, cationic polyacrylamide can be used as water flooding agent and thickening agent to improve the efficiency and production of oilfield exploitation.
In conclusion, as an important polymer material, cationic polyacrylamide has made great progress in its synthesis and application. In the future, with the increasing requirements of sustainable development, cationic polyacrylamide will be applied and developed in a wider range of fields and at a higher level.
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
