Furthermore, Smedic has drafted ten national and industry standards regulating the quality of composite carbon sources, composite coagulants, sodium acetate, and specialized nitrifying bacterial agents.
Anionic Polyacrylamide (APAM) is a highly efficient water-soluble polymer formulated via the copolymerization of acrylamide monomers and acrylic acid salts, or through the partial alkaline hydrolysis of polyacrylamide. Synthesized through sophisticated free-radical polymerization pathways, our APAM molecular weight profiles range from 5 million to over 25 million Daltons, paired with custom charge densities (hydrolysis levels) between 10% to 60%.
By controlling radical polymerization temperatures and incorporating specific chain-transfer agents, Smedic yields UHMW APAM chains exceeding 22 Million Daltons. These expansive chains accelerate floc formation through particle bridging.
We are researching enzymatic acrylamide synthesis pathways utilizing biological catalysts to replace traditional copper-catalyzed hydration routes. This significantly reduces residual monomer toxicity (free acrylamide content < 0.05%).
By modifying charge distributions, Smedic optimizes adsorption kinetics on specific mineral or waste particles. Our specialized molecular structures perform reliably under high-shear conditions.
| Polymer Type (APAM Series) | Molecular Weight (Million Da) | Degree of Hydrolysis (%) | Typical Industrial Application | Optimal pH Range |
|---|---|---|---|---|
| Smedic APAM-HW12 | 12 - 15 | 15 - 20 | Mining tailings sedimentation & wash-water recycling | 6.0 - 9.0 |
| Smedic APAM-UH22 | 20 - 25 | 25 - 35 | Municipal sludge thickening & industrial paper retention | 7.0 - 10.0 |
| Smedic APAM-OR18 | 16 - 18 | 10 - 15 | Enhanced Oil Recovery (EOR) polymer flooding | 5.5 - 8.5 |

Industrial scale optimization requires reagents customized for specific solid-liquid separation challenges. Anionic Polyacrylamide forms the backbone of these process optimizations.
In gold, copper, iron, and coal preparation plants, our APAM acts as a primary settling flocculant in deep-cone thickeners. It accelerates settling rates, increases underflow density, and enables rapid water recycling, helping mines maintain zero-discharge operations.
Our polymers improve sludge dewatering performance on belt presses, centrifuge decanters, and screw presses. By forming robust, shear-resistant flocs, they reduce moisture content in filter cakes and lower transport costs.
Our polymers improve mobility ratios during waterflooding, allowing operators to sweep trapped oil from mature reservoirs. Smedic's EOR formulations maintain stable viscosity under high shear, salinity, and temperature conditions.
APAM acts as a retention and drainage aid, improving fiber distribution and filler retention on the wire. This enhances sheet formation, dry strength, and drainage speeds, increasing production capacity.
Our smart production facilities utilize advanced Distributed Control Systems (DCS) for precise control over polymerization temperature, reaction times, and monomer addition. This ensures consistent batch quality and reduces impurities. Smedic's integrated supply chain, from raw material procurement to final distribution, helps shield global buyers from market volatility.
In-process monitoring track molecular weight, free monomer limits, and particle size distribution. No batch is released from our warehouses without passing multi-point quality control testing.
With warehouse hubs located near major shipping hubs like Tianjin, Qingdao, and Shanghai, we support flexible freight arrangements (FOB, CIF, DDP) and maintain prompt shipping times.
We maintain deep partnerships with domestic acrylonitrile manufacturers to secure priority access to key inputs, ensuring stable production capacity even during global shortages.
Our export solutions are designed to simplify global logistics. We customize our packaging, documentation, and technical support to match the import regulations of target countries.

We provide full documentation support, including REACH registration, SGS reports, and certificate of origin paperwork.
Our technical team answers common questions about the application and storage of Anionic Polyacrylamide.
APAM should be dissolved in clean water at a concentration of 0.1% to 0.3%. Slow, steady mechanical agitation (around 100-300 RPM) is recommended to prevent polymer shear degradation. The water temperature should be kept between 20°C and 40°C to ensure complete dissolution, which typically takes 40 to 60 minutes.
The hydrolysis level dictates the net negative charge density along the polymer chain. Low hydrolysis (10-15%) is suited for slightly acidic streams or slurries with low inorganic charge, while higher hydrolysis (30-40%) is ideal for neutral or alkaline mineral slurries where electrostatic repulsion needs to be overcome by calcium or magnesium bridges.
When stored in its original, unopened packaging in a cool, dry warehouse, dry granular APAM has a shelf life of up to 24 months. Liquid emulsions should be used within 6 months and should be agitated occasionally to prevent settling.
Our production lines use DCS control systems to manage temperature and reaction conditions. Every batch undergoes testing for viscosity, molecular weight, hydrolysis level, insoluble content, and residual monomer levels prior to shipment.
