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.
