What is nonionic polyacrylamide PAM?

Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation. Many friends have little knowledge of this type of polyacrylamide. Today, I will introduce the characteristics, efficacy, and usage of nonionic polyacrylamide PAM.

What are the characteristics of nonionic polyacrylamide?

1. Characteristics of nonionic polyacrylamide Nonionic polyacrylamide is a high polymer with a high molecular weight and a low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film-forming, relating, and colloidal stability.

How strong is a cationic Pam compared to a nonionic Pam?

Besides, the average of maturated floc strength factor for cationic PAM (77 %) was somewhat greater than that for either anionic or nonionic PAMs (both ≈ 69 %).

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.

Are cationic polyacrylamides better than anionic polyamides?

They suggested that cationic polyacrylamides (PAM) produced floc aggregates with larger size, greater shear-resistant ability and higher regrowth capacity than anionic one, arising from the contribution of charge neutralization and bridging effects , , .

Why is Pam adsorption slower than cationic?

For nonionic PAM, its adsorption was found to be much slower and weaker than that of cationic one, probably due to the screening of the electrical double layer on the negatively charged particle surface , .
