Can anionic polyacrylamide improve climatic durability of solidified waste rock fine?

In order to improve the climatic durability of solidified waste rock fine (WRF), anionic polyacrylamide (APAM) was innovatively introduced to amend solidified WRF in this study. The effects of APAM content, freeze-thaw (F-T), and wet-dry (W-D) cycles on the mechanical behaviors of solidified WRF were explored.

What is the molecular weight of anionic polyacrylamide?

Anionic Polyacrylamide Molecular weight of anionic polyacrylamide: As an industrial sewage treatment agent, the molecular weight is between 6 million and 18 million. The misunderstanding we need to understand: It is not that the higher the molecular weight, the better the effect of treating sewage.

Does anionic polyacrylamide have a good flocculation effect?

Anionic polyacrylamide has a long molecular chain, and a large number of long chains describe the surface of a huge group. This achieves a very good flocculation effect, using molecular chains to directly bridge and link each other to form a strong floc, thus achieving a water purification effect. Anionic Polyacrylamide

How does anionic polyacrylamide affect water purification?

This achieves a very good flocculation effect, using molecular chains to directly bridge and link each other to form a strong floc, thus achieving a water purification effect. Anionic Polyacrylamide Molecular weight of anionic polyacrylamide: As an industrial sewage treatment agent, the molecular weight is between 6 million and 18 million.

Is polyacrylamide a coagulant?

Polyacrylamide is a polymer flocculant widely used in the water purification market. It is also often used as a coagulant. The raw material of polyacrylamide is made of polyacrylonitrile. Under the environment, acrylamide can become acrylamide through the process of hydrolysis, and finally polyacrylamide is formed through suspension polymerization.

What is Pam/PAC-Fe(III) polyacrylamide/polyanionic cellulose composite physical hydrogel?

In this work, a series of Fe (III)-crosslinked polyacrylamide/polyanionic cellulose composite physical hydrogels [PAM/PAC-Fe (III)] were firstly prepared via polymerizing acrylamide in PAC solution free of chemical crosslinkers, and followed by posttreatment in 0.1 M iron chloride solution.
