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.

Is non ionic polyacrylamide a water soluble polymer?

Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.

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:

Why are polyelectrolytes mixed with non-ionic polymers?

Also, because of their high water absorption and/or brittle nature [ , , ], polyelectrolytes are often blended with non-ionic polymers to form mechanically-strong membranes and then soaked in KOH solutions [ 30, 31] to obtain the ionic conductivity.

What is a nonionic polymer (Pam)?

Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain. It can adsorb solid particles suspended in water and bridge between particles to form large floccules, accelerate the sedimentation of particles in suspension, accelerate the clarification of solution, and promote filtration.

What are the functions of nonionic polyacrylamide PAM?

Therefore, nonionic polyacrylamide PAM has the functions of flocculation, dispersion, thickening, adhesion, film formation, gelation, and colloid stability. Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation.
