Cationic polyacrylamide is a kind of ionic polymer with certain cationic properties. Because of its excellent physical and chemical properties, cationic polyacrylamide has been widely used in many fields.
Firstly, cationic polyacrylamide is an important coagulant and precipitator in the field of water treatment. In the treatment of suspended matter and organic matter and other impurities in the water, cationic polyacrylamide can be adsorbed with these negatively charged substances, so as to promote its condensation and precipitation. In addition, cationic polyacrylamide can increase the viscosity of water and slow the flow rate, thus improving the solid-liquid separation. Therefore, it is widely used in urban sewage treatment and drinking water purification.
Secondly, in the field of paper manufacturing, cationic polyacrylamide can be used as a water retaining agent and rheological control agent for pulp. During the paper manufacturing process, the water in the pulp is gradually removed, causing the paper to dry and deform. In order to avoid this situation, cationic polyacrylamide can be added to improve the water retention performance of the pulp. In addition, CPAM can also regulate the rheological properties of the pulp, thereby improving the formability and strength of the paper and improving the quality of the paper.
In the field of production, CPAM can be used as a viscosifier to improve oil recovery efficiency. In a well, oil and water mix, slowing the flow of oil and reducing the efficiency of recovery. At this time, the addition of cationic polyacrylamide can make the viscosity difference between oil and water, so as to increase the flow resistance of oil and improve the efficiency of oil recovery.
In short, cationic polyacrylamide is a very important polymer material, widely used in water treatment, paper manufacturing, oilfield exploitation and other fields, and has a good application effect.
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
