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.

Which polyacrylamide is used as a pulp dispersant?

Anionic polyacrylamide can be used as a pulp dispersant. 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.

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 is the association between Pam and 10 million molecular weight?

The association of PAM with 10 million molecular weight in solution shows a loose network structure of micro-gels with a size of about several hundred nanometers.

What is the molecular weight of Pam?

The oxide content (wt.%) of PC. PAM was supplied by Sinopharm Co., Ltd. (Beijing, China) and McLean Co. Ltd. (Shanghai, China). In order to compare the workability change of cement paste, the molecular weight of PAM varied greatly, among them 3, 10, and 17 million with the unit of Da (g/mol).

What type of polyacrylamide is Apam?

Amphoteric Polyacrylamide. APAM is formed by hydrolysis and copolymerization of vinyl amide and vinyl cationic monomer acrylamide monomer. It is an irregular zwitterionic polymer with both positive and negative charges on the molecular chain. Non-ionic Polyacrylamide.
