1. preparation of PAM aqueous solution should be in enamel, galvanized, aluminum or plastic barrel, no preparation and storage in the vessel.
2. dissolution, should pay attention to the product evenly and slowly, in dissolving into the mixing and heating measures should be avoided with solid, solution at the proper temperature, prepare, and should be avoided for a long series of mechanical shearing. it is recommended that mixer 60-200/min, will cause the polymer degradation, affect the results.
3. PAM water solution to be active now, and when the dissolution of placed for a long time, depending on the water quality of its performance will gradually decrease.
4. After adding a flocculant aqueous suspensions, and stir furiously for a long time, will undermine the formation of flocs.
