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.

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.

How to make Apam polymer?

Strong acid, strong alkali, and high salt water are not suitable. The concentration of the polymer solution is recommended to be 0.1%-0.3%, that is, add 1g-3g PAM polymer powder to 1 liter of water. The appearance of APAM is white powder with a molecular weight ranging from 6 million to 25 million.

Is Apam soluble in water?

The appearance of APAM is white powder with a molecular weight ranging from 6 million to 25 million. With good water solubility, it can dissolve in water in any proportion, but is insoluble in organic solvents. Meanwhile, the effective PH value ranges from 4 to 14.

What is anionic Pam used for?

At present, anionic PAM is most used in the paper industry. In food industry, it is used for cane juice clarification and syrup phosphorus floatation extraction in the production of cane sugar and beet sugar. Used in the flocculation and clarification industry of enzyme fermentation broth.
