Polyacrylamide (PAM) is a versatile polymer, and its effectiveness across various applications hinges on its specific type. At NINGBO INNO PHARMCHEM CO.,LTD., we understand the importance of selecting the right PAM variant for optimal performance. PAMs are broadly classified based on their ionic charge and molecular structure: Anionic, Cationic, Non-ionic, and Amphoteric.

Anionic Polyacrylamide (APAM): APAM carries a negative charge due to the presence of carboxylate groups, typically formed through the hydrolysis of amide groups. It is highly effective in flocculating positively charged suspended particles and is widely used in water treatment, mining, and papermaking. APAM's performance is influenced by factors like pH and the presence of multivalent cations, which can enhance its flocculation efficiency. Its applications range from treating industrial wastewater to aiding in mineral processing and improving paper retention.

Cationic Polyacrylamide (CPAM): CPAM possesses a positive charge, making it particularly effective in flocculating negatively charged particles and organic matter. It is extensively used in sludge dewatering in municipal and industrial wastewater treatment plants, as well as in the paper industry for retention and drainage. The degree of cationicity significantly influences its performance, with higher cationicity generally being more effective for sludge treatment.

Non-ionic Polyacrylamide (NPAM): NPAM carries no net electrical charge. It functions primarily through bridging mechanisms to aggregate particles. NPAM is often preferred in applications where the presence of electrolytes might interfere with ionic PAM performance, such as in highly saline water or certain industrial processes. It is also utilized in water treatment, oil recovery, and textile applications.

Amphoteric Polyacrylamide (APAM): Amphoteric PAM contains both positive and negative charges along its molecular chain. This dual charge capability makes it exceptionally versatile, allowing it to effectively flocculate a wide range of particles, including those with mixed or changing charges. Amphoteric PAM can exhibit superior performance in complex water matrices and is increasingly used in challenging wastewater treatment scenarios and specialized industrial applications where its unique properties offer distinct advantages.
