1. Configuration concentration
The molecular weight and viscosity of anionic polyacrylamide pam are high, so the ratio concentration is generally between 0.1% to 0.5%, and the solution ratio concentration can also be adjusted according to the specific situation on site.
2. Dissolving container
The dissolving operation should be carried out in the mixing tank of plastics, ceramics, stainless steel, etc.
3. Mixing process
The shearing force of the PAM molecular chain in the solution will cause the molecular chain to break and degrade, which affects the performance. Therefore, when dissolving and diluting PAM, the stirring time and the stirring intensity should be reduced as much as possible; the stirring speed should generally be controlled at 50-250 rpm/min. It should not be too fast. When using PAM solution, avoid strong mechanical stirring as much as possible.
