1. Product Specifications & Manufacturing Process
As a leader in specialty polymer synthesis, Gongyi Xinqi offers a comprehensive polyacrylamide (PAM) portfolio with tailored ionic characteristics: cationic for high-charge applications, anionic for mineral processing, and non-ionic for pH-sensitive systems. Our oxygen-free continuous polymerization technology enables precise molecular weight control (5-25 million Da) with pharmaceutical-grade purity (>99% monomer conversion). The proprietary purification system maintains residual acrylamide below 0.3%, exceeding the EU REACH 0.1% standard for potable water applications.

2. Synthesis Technology Breakthroughs

Initiation System Optimization: The redox system (ammonium persulfate/TMEDA) achieves 92% initiation efficiency at reduced temperatures (35-50°C vs conventional 70°C). Urea serves dual functions as chain transfer agent and thermal stabilizer, enabling molecular weights up to 15 million Da without crosslinking.

Energy-Smart Production: Continuous flow technology reduces cooling energy consumption by 30% through advanced heat exchange networks, delivering 15% higher space-time yield than batch processes.

Custom Polymer Engineering: Computer-controlled monomer feed adjustment allows precise hydrolysis degree (10-50%) and charge density (±0.5-8 meq/g) customization for specific industrial needs.

3. Industry-Specific Performance Data

Mining Wastewater Treatment: Cationic PAM (12 million Da, 40% charge) achieves 98% turbidity reduction at 2 ppm dosage in copper tailings, with 60% lower sludge volume versus traditional coagulants in Shanxi coal mines.

Enhanced Oil Recovery: Nano-dispersed PAM (80-150 nm) shows 120% higher injectivity in 50 mD formations, boosting oil displacement efficiency by 18% through viscoelastic flow control.

Biomedical Applications: FDA-cleared non-ionic PAM hydrogels with tunable stiffness (0.5-80 kPa) serve as 3D bioprinting scaffolds for tissue engineering.

4. Quality Assurance System
ISO 17025-certified testing includes:

Rheological profiling (Haake RheoStress, 0.1-1000 s⁻¹ shear range)

Molecular weight distribution (GPC-MALLS)

Accelerated stability studies via Arrhenius modeling

5. Eco-Innovation
EcoPAM® features biodegradable ester linkages (90% degradation in 180 days per OECD 301B), reducing aquatic toxicity (Daphnia magna LC50 from 12% to 0.8%) in textile wastewater treatment.
