Understanding Charge Density, Molecular Weight Metrics, and Flocculation Kinetics
Polyacrylamide (PAM) is a linear water-soluble polymer synthesized from acrylamide monomers. Anionic Polyacrylamide (APAM) is copolymerized with acrylic acid salts or hydrolyzed from polyacrylamide to introduce negatively charged carboxylate groups (—COO⁻) along the polymer backbone.
APAM operates primarily through polymer bridging. The long-chain molecules adsorb onto the surface of suspended solid particles simultaneously. By spanning across multiple particles, APAM forms dense, fast-settling micro-flocs and large macro-flocs, rapidly clarifying turbidity.
In suspended systems containing positively charged mineral particles or heavy metals, the negative charges of APAM's carboxylate groups neutralize surface charges, reducing electrostatic repulsion (zeta potential) and facilitating rapid aggregation.
| Product Grade | Molecular Weight (Million Da) | Degree of Hydrolysis (Charge Density) | Solid Content (%) | Dissolution Time (Mins) | Primary Industrial Field |
|---|---|---|---|---|---|
| APAM Ultra High MW | 18 - 25 Million | 20% - 30% Low-Medium | ≥ 88% Powder | ≤ 60 min | Enhanced Oil Recovery (EOR), Mineral Tailings |
| APAM High MW | 12 - 18 Million | 30% - 40% Medium-High | ≥ 88% Powder | ≤ 50 min | Municipal Wastewater, Industrial Clarification |
| APAM Medium MW | 6 - 12 Million | 10% - 20% Low | ≥ 88% Powder | ≤ 45 min | Sugar Refining, Paper Retention & Dispersant |
| NPAM (Nonionic) | 8 - 15 Million | 0% - 5% Ultra Low | ≥ 88% Powder | ≤ 60 min | Acidic Wastewater, Coal Washing Tailings |
