What is anionic polyacrylamide (Apam)?

Anionic polyacrylamide (Anionic PAM, APAM) Structure and properties: Anionic PAM is a water-soluble polymer. By introducing these anionic groups on the polymer backbone, APAM can react with positively charged substances. It is mainly used for flocculation, sedimentation and clarification of various industrial wastewaters.

What are the different types of polyacrylamide (PAM)?

According to its ionic properties, PAM is divided into three main types: cationic (Cationic PAM, CPAM), anionic (Anionic PAM, APAM) and nonionic (Nonionic PAM, NPAM). These three types have significant differences in structure, function and application. 1. Cationic polyacrylamide (Cationic PAM, CPAM) Structure and properties:

What is polyacrylamide (PAM) used for?

In water treatment and industrial production, polyacrylamide (PAM) is widely used as an important flocculant in wastewater treatment, pulp production, ore processing, and other fields. Based on its ionic properties, PAM can be divided into anionic polyacrylamide (APAM) and cationic PAM (CPAM).

What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

What is nonionic polyacrylamide?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.

What is cationic polyacrylamide (CPAM)?

2. Cationic polyacrylamide (CPAM) This type of polymer has molecules that carry positive charge. Cationic PAM can pick up negatively charged particles (organic materials like carbon or human waste). CPAM is very efficient in usage and has high dehydration rate.
