Engineered for precise solid-liquid separation, rapid sludge dewatering, and municipal wastewater clarification.
Established in 2011 within the Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd. has scaled into a global titan of water-soluble polymer manufacturing. Maintaining a consistent 10% annual business growth trajectory over the past decade, our production facilities surpassed an annual polyacrylamide capacity of 50,000 Metric Tons in 2018.
Governed by strict ISO9001:2008 Quality Management Certification, Oubo integrates cutting-edge bio-catalytic monomer synthesis technology with automated continuous polymerization lines. We prioritize environmental safety, eco-friendly chemical footprints, and precision charge tuning for diverse industrial solid-liquid separation challenges.
Understanding charge density, molecular weight distribution, and reaction dynamics in wastewater flocculation.
CPAM is synthesized by copolymerizing acrylamide (AM) with cationic monomers such as DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride). Charge density ranges from 5% to 80% based on application requirements.
Negatively charged suspended solids, organic sludge particles, and colloidal dyes are destabilized through charge neutralization. Positively charged quaternary ammonium groups compress the electrical double layer, facilitating immediate particle collapse.
With ultra-high molecular weights (ranging from 6 Million to 12 Million Daltons), long polymer chains adsorb onto multiple suspended particles simultaneously, generating compact, dense flocs with exceptional shear resistance for mechanical dewatering.
| Grade / Product Type | Ionic Charge (%) | Molecular Weight (Million) | Solid Content (%) | Dissolving Time (Mins) | Primary Application |
|---|---|---|---|---|---|
| CPAM Ultra-Low Charge | 5 - 15 % | 10 - 12 Million | ≥ 88% | ≤ 60 | Paper manufacturing retention aid & river dredging |
| CPAM Medium Charge | 20 - 40 % | 8 - 10 Million | ≥ 88% | ≤ 50 | Municipal sewage sludge dewatering (Belt Press) |
| CPAM High Charge | 50 - 60 % | 6 - 8 Million | ≥ 88% | ≤ 45 | Textile dyeing effluent & organic wastewater |
| CPAM Super-High Charge | 70 - 80 % | 5 - 7 Million | ≥ 88% | ≤ 45 | Centrifuge/Decanter municipal sludge dewatering |
Located in the Free Trade Zone of Qingdao, Oubo Chemical bridges advanced chemical processing with streamlined maritime supply chains.
