Cationic polyacrylamide is a special type of polyacrylamide that contains cationic groups in its molecular structure. This makes it useful in many fields. The applications of cationic polyacrylamide in water treatment, pulp and paper, and sediment treatment are described below.
Firstly, cationic polyacrylamide is widely used in the field of water treatment. Due to its cationic properties, CPAM can combine with negative ion particles, suspended matter and organic matter in water to form flocculates. This helps to purify water and improve water quality. At the same time, cationic polyacrylamide can also be used as a precipitation agent to accelerate the sedimentation rate of suspended solids in water, thereby improving the efficiency of water treatment. In addition, CPAM can also be used in sludge dewatering processes to reduce sludge volume and reduce treatment costs.
Secondly, cationic polyacrylamide plays an important role in the pulp and paper industry. Pulp is often dispersed and stabilized in the manufacturing process to ensure the quality and performance of the paper. CPAM is widely used in pulp processing as a dispersant and thickener. It can enhance the fiber binding force in the pulp and improve the strength and durability of the paper. At the same time, CPAM can also well suppress static electricity in the pulp, improve the flatness and gloss of the paper.
In addition, cationic polyacrylamide also has important applications in sediment treatment. Sediments are often present in many industrial processes and natural environments, such as mud, bottom mud, etc. CPAM can be used as a flocculant to treat these deposits. It is able to combine with sediment particles to form larger flocs, thus promoting sedimentation and separation. This characteristic makes CPAM play an important role in sewage treatment, mud treatment, lake restoration and so on.
In summary, cationic polyacrylamide is a kind of polymer compound with application value. Its applications in the fields of water treatment, pulp and paper, and sediment treatment have made important contributions to improving the environment, increasing production efficiency, and conserving resources.
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
