Understanding the charge density dynamics, copolymerization mechanisms, and structural kinetics of linear water-soluble cationic polymers in heavy industrial solid-liquid separation.
Cationic Polyacrylamide carries positively charged quaternary ammonium groups along its backbone (e.g., DAC or DMC monomers). In colloidal suspensions with negatively charged organic particles, CPAM destabilizes electrical double-layers via rapid charge neutralization, collapsing zeta potential to near-zero levels.
Featuring ultra-high molecular weights ranging from 5 Million to over 15 Million Daltons, CPAM macromolecular chains extend deep into the aqueous phase. Individual polymer threads adsorb simultaneously onto multiple suspended solids, forming large, fast-settling macroscopic flocs.
At high cationic charge densities (40%–80% mole content), the polymer chain attaches to particle surfaces in localized patches. This creates alternating positively and negatively charged domains across micro-flocs, driving intense electro-viscous coagulation under high shear stress conditions.
| Parameter / Grade | Molecular Weight (Million Daltons) | Charge Density (Degree of Cationicity) | Solid Content (%) | Dissolving Time (Mins) | Primary Application Focus |
|---|---|---|---|---|---|
| CPAM Low-Charge | 10.0 - 15.0 | 10% - 20% Mol | ≥ 88% | ≤ 60 | Papermaking retention aids, river dredging, low-organic municipal sludge |
| CPAM Medium-Charge | 8.0 - 12.0 | 30% - 40% Mol | ≥ 88% | ≤ 50 | Textile dyeing wastewater, belt filter press dewatering, food processing waste |
| CPAM High-Charge | 6.0 - 10.0 | 50% - 60% Mol | ≥ 88% | ≤ 45 | Centrifugal dewatering, high-fat food industrial sludge, tannery effluents |
| CPAM Ultra-High Charge | 5.0 - 8.0 | 70% - 80% Mol | ≥ 90% | ≤ 40 | Pharmaceutical sludge, biochemical sludge, high-speed centrifuge dewatering |

Polyacrylamide (PAM) is a synthetic resin prepared by polymerizing acrylamide. It is a white, solid, water-soluble polymer of acrylamide, mostly used as a flocculant, coagulant, and filtration aid in a whole range of applications that are determined by its physical form and its ionic type (nonionic, anionic, cationic, and Mannich).
It is utilized in secondary oil recovery, as a thickening agent, a flocculant, and an absorbent. Moreover, polyacrylamide is also employed to separate macromolecules of different molecular weights.

Engineered formulas designed for municipal sewage, pulp and paper, enhanced oil recovery, mining tailings, and industrial effluent treatment.
As a cationic flocculating agent, CPAM is predominantly used in industrial solid-liquid separation processes including sedimentation, clarification, thickening, and sludge dewatering. Highly effective across belt presses, screw presses, and high-speed centrifuges, CPAM dramatically lowers cake moisture content.
Increasingly stringent environmental regulations accelerate the need for ultra-pure water discharge. Beyond urban sewage, CPAM works extensively in leather processing, citric acid production, vegetable protein extraction, dyeing, pharmaceuticals, incense manufacturing, and chemical effluent purification.
In the paper industry, cationic polyacrylamide functions as a vital dry strength agent, retention aid, drainage promoter, and filter aid. It significantly enhances paper quality, increases physical sheet strength, and reduces fiber loss while recycling white water during deinking processes.
Polyacrylamide polymers are extensively deployed across oil recovery, profile control, water-plugging agents, drilling fluids, and hydraulic fracturing fluids. They effectively suppress shale swelling, reduce fluid loss, lubricate drill strings, cool bits, and carry rock cuttings out of the borehole during cementing and completion operations.
Key application sectors include:
Mining & Mineral Processing: High-molecular polyacrylamides accelerate solid-liquid separation in coal washing, mineral tailing thickening, filtration, centrifugation, and hydrometallurgical recovery of Gold, Silver, Iron, Nickel, and Copper.
Sugar Industry: Acts as an ultra-pure clarification and flotation aid in sugarcane and sugar beet juice clarification, accelerating impurity drop-out.
Textile Industry: Functions as a high-performance sizing agent, finishing auxiliary, and fabric treatment agent, delivering superior yarn strength while treating dye-rich wastewater effluent.
