Commissioning method for PAM viscosity

It can be reduced in dosage or diluted. Note that powdered PAM can be stored in dry, cool places for more than two years, but after being formulated into a solution, its storage time is very limited.

Generally, when the solution concentration is 0.1%, the non-anionic polymer solution does not exceed one week; the cationic polymer solution does not exceed one day. The stability of the solution is related to the concentration. The thicker the solution (eg 3% to 5%), the longer the solution will be stored. However, 3% to 5% of the solution cannot be directly treated with sewage and diluted before use.

The cationic PAM solution is relatively stable at pH < 5.5, and will rapidly fail due to hydrolysis at pH > 6. It is sensitive to iron ions and calcium and magnesium ions than anionic polymers.
