(anionic, cation ,nonionic )PAM

1) Polyacrylamide ( PAM )
2) PAM is the water-soluble high molecular polymer.
3) Good water solubility
4) High quality....
the physical nature
Colorless or light yellow thick polyacrylamide gel, odorless, neutral, soluble in water, insoluble in ethanol, acetone, when the temperature exceeds 120 °C easy to decompose, flocculation, sedimentation, the role of reinforcement, etc.
Non-ionic polyacrylamide is non-macromolecular chain ionic groups, but with many substances amide, such as clay.
Cellulose to produce hydrogen.
Adsorption and flocculation due to bridging
Cationic This product is a polymer electrolyte solution.
With a positive charge (active basis).
Of suspended organic colloids and organic compounds can be effectively condensed, and to strengthen the solid-liquid separation process
Anionic polyacrylamide in neutral and alkaline media showed the characteristics of polymer electrolyte, the electrolyte salt sensitive.
Associated with the high price of metal ions can form insoluble gel

PAM application of the strong)
1, in the papermaking process as a retention aid, reinforcing agent.

2, as a coagulant in water treatment, flocculation, sludge dewatering agent.
3, as precipitation agent in oil drilling, oil displacement agent.

4, PAM also widely used in thickening, colloidal stability, drag reduction, bond, film, bio-medical materials and so on.
