Overview

The Shouxin brand of zwitterionic polyacrylamide is supported by Chinese and American academicians. Due to the presence of cationic and anionic groups in its molecules, zwitterionic polyacrylamide flocculants not only have the characteristics of general cationic flocculants, but also exhibit superior performance. Coagulants such as zwitterionic polyacrylamide can be used over a wide range of pH values, with higher filtration capacity and lower cake moisture content. They can also be used for strong acid leaching of ores or recovery of valuable metals from acidic catalysts containing metals.

【Shouxin brand's zwitterionic polyacrylamide is supported by Chinese and American academicians】The zwitterionic polyacrylamide flocculant has been widely used in the field of water treatment due to its excellent flocculation performance and adaptability. It is a polymer with cationic and anionic properties. It adjusts its own charge state by changing the pH value and ionic strength, thus adapting to the flocculation needs under different water quality conditions. APAM usually exists in the form of solid powder or lotion, and is widely used to remove suspended particles, organics and chroma in water treatment process.

Due to the presence of cationic and anionic groups in its molecules, zwitterionic polyacrylamide flocculants exhibit superior performance in addition to the typical characteristics of cationic flocculants. This type of flocculant can be used over a wide range of pH values, with higher filtration capacity and lower cake moisture content. It can also be used for strong acid leaching of ores or recovery of valuable metals from acidic catalysts containing metals. The zwitterionic type is not a mixture of anionic and cationic types. If cationic polyacrylamide is used in combination with anionic polyacrylamide, a reaction will occur to produce a precipitate.

The hydrolysis degree of polyacrylamide affects the actual use effect of polyacrylamide. Therefore, the hydrolysis degree of polyacrylamide is a very important technical indicator in addition to ionic type, molecular weight, and ionic degree, which is crucial for the practical application of polyacrylamide. There are four factors that affect the hydrolysis degree of polyacrylamide: dissolution time, dissolution concentration, stirring time, and alkali addition ratio. Therefore, under certain hydrolysis conditions, there is a close relationship between hydrolysis degree and hydrolysis time. By conducting experiments under different conditions, the appropriate hydrolysis time can be obtained.

Polyacrylamide of zwitterionic polyacrylamide flocculant is a general term for acrylamide monomer or polymer copolymerized with other monomers. It is a water-soluble linear polymer synthesized artificially. Its products are mainly divided into dry powder and lotion. According to different structures, it can be divided into non-ionic, anionic, and cationic types. Because the main chain of polyacrylamide contains a large number of amide groups and has high chemical activity. Therefore, various polyacrylamide derivatives can be manufactured through deformation, and the products are widely used in fields such as papermaking, mineral processing, petroleum production, metallurgy, building materials, and sewage treatment.

　　Advantages of zwitterionic polyacrylamide flocculant:

Wide applicability: It can adapt to the flocculation needs under different water quality conditions. It has good flocculation performance in acidic, alkaline, and neutral environments, and has good removal effects on different types of suspended substances and organic matter.

Charge neutralization and adsorption characteristics: It has both cationic and anionic properties, and can aggregate suspended substances into larger particles through charge neutralization and adsorption, effectively settling to the bottom of the water body and achieving solid-liquid separation.

Salt resistance and hardness resistance: It still has good flocculation effect in high salinity and high hardness water bodies, and can effectively treat water quality from different sources such as seawater, freshwater, and groundwater.

Environmental friendliness: Compared with traditional inorganic flocculants, APAM flocculants have lower toxicity and secondary pollution risks. Its degradation products have a relatively small impact on the environment and meet environmental protection requirements.

　　Application areas of zwitterionic polyacrylamide flocculant:

Wastewater treatment: widely used in urban sewage treatment plants and industrial wastewater treatment systems, it can effectively remove pollutants such as suspended solids, ammonia nitrogen, COD, etc., and improve the treatment efficiency of wastewater.

Drinking water purification: It can be used for primary purification of drinking water sources, removing harmful substances such as turbidity, organic matter, and heavy metals, and improving the safety of water quality.

The textile, papermaking, and printing and dyeing industries can remove chromaticity, suspended particles, and organic matter during the textile, papermaking, and printing and dyeing processes, ensuring product quality during the production process.

Mining and coal industries: widely used in tailings treatment in mining and coal industries, it can improve ore dewatering rate and reduce solid waste emissions.

【Shouxin brand's zwitterionic polyacrylamide is supported by Chinese and American academicians】As an efficient and adaptable water treatment agent, zwitterionic polyacrylamide flocculant has broad application prospects in the field of water treatment. By adjusting the pH value, ion strength, and dosage, it is possible to achieve optimized flocculation for different water qualities. In the future, we still need to further research and improve APAM flocculants to enhance their efficiency and economy, and contribute to the clean utilization of water resources and environmental protection.
