2026-04-14 10:51:37
Nonionic Polyacrylamide(NPAM)is a water-soluble polymer with high molecular weight and low ionic charge.It is widely applied across industries for flocculation,dispersion,thickening,and adhesion,especially in water treatment,papermaking,oil recovery,mining,textiles,and agriculture.
1.Water&Wastewater Treatment
Flocculant for acidic/high-salinity wastewater:Effective in industrial wastewater(paper,mining,steel,textile,petrochemical)and municipal sewage,forming large flocs to accelerate sedimentation.
Sludge dewatering:Improves filtration and reduces moisture content in sludge from sewage and industrial processes.
Drinking water clarification:Used in river/lake water treatment with inorganic coagulants.
2.Papermaking
Retention&drainage aid:Keeps fine fibers/fillers in paper,boosts production speed.
Dry strength additive:Enhances paper tensile and burst strength.
Deinking assistant:Flocculates ink particles in recycled pulp processing.
3.Oil&Gas Industry
Enhanced Oil Recovery(EOR):Thickens injected water to improve sweep efficiency.
Drilling fluid additive:Controls viscosity,stabilizes boreholes,reduces friction.
Oily wastewater treatment:Separates oil droplets and suspended solids.
4.Mining&Mineral Processing
Tailings/coal wastewater clarification:Settles fine particles,recovers minerals.
Concentration&filtration:Improves solid–liquid separation in ore processing.
5.Textile Industry
Textile sizing agent:Strengthens yarns,reduces weaving breakage.
Finishing&anti-static:Improves fabric smoothness and antistatic properties.
6.Agriculture&Soil Management
Soil conditioner:Improves structure,water retention,and erosion resistance.
Sand fixation:Crosslinked NPAM sprayed on desert/sandy soil stabilizes dunes.
7.Other Uses
Construction:Chemical grouting for dam/foundation sealing.
Food industry:Sugarcane juice clarification.
Electroplating/leather:Decolorizes and clarifies wastewater.
