Get PriceWhat 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 anionic polyacrylamide?
Anionic polyacrylamide is suitable for higher density, inorganic suspension substance with positive charge and is neutral or basic, with thick suspension particles of 1mm-10mm. Polyacrylamide comes in various forms such as granular, liquid oil emulsion, tablet, and block forms.
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 determines the molecular weight of anionic polyacrylamide?
The molecular weight is determined by the type and concentration of the reaction initiator and the reaction parameters. Anionic polyacrylamide has no systemic toxicity to aquatic organisms or micro-organisms. The polymer is much too large to be absorbed into tissues and cells.
What are the synthesis methods for anionic polyacrylamide?
Homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization are the main six kinds of synthesis technologies of APAM. This review summarizes the synthesis methods for anionic polyacrylamide.
What is cationic polyacrylamide (CPAM)?
Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.
