Qingdao Oubo Chemical Co., Ltd. delivers global polymer solutions backed by decade-long growth, patented biological synthesis, and stringent quality control.
Understanding the molecular architecture, charge density mechanics, and biological polymerization process driving high-efficiency flocculation.
Polyacrylamide (PAM) is a water-soluble synthetic resin synthesized via acrylamide polymerization. Cationic Polyacrylamide (CPAM) is copolymerized with cationic monomers such as DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride). This endows the polymer backbones with positively charged quaternary ammonium groups, ideal for destabilizing negatively charged colloidal suspended solids.
Most organic suspended solids, micro-algae, and industrial sludges carry a net negative surface zeta potential. Oubo CPAM neutralizes this surface charge rapidly, reducing electrostatic repulsion between particles. This micro-floc formation is immediately followed by long-chain polymeric bridging, forming large, resilient macro-flocs that settle or dewater rapidly under high shear conditions.
Oubo Chemical utilizes advanced biological enzymatic methods to produce acrylamide monomers, a core patented technical advantage. Biological catalysis operates under ambient conditions, producing exceptionally high-purity monomer feedstocks free of toxic catalytic copper or iron impurities. This allows for controlled polymerization, yielding molecular weights ranging from 5 Million to over 15 Million Daltons.
Selecting the optimal cationic charge degree (%) and molecular weight (MW) is critical for achieving clear filtrate and dense sludge cake formation.
| Polymer Grade | Ionic Type | Cationic Charge Degree (%) | Molecular Weight (Million) | Solid Content (%) | Dissolution Time (Mins) | Primary Industrial Application |
|---|---|---|---|---|---|---|
| Oubo CPAM-1015 | Low Cationic | 10% - 20% | 10 - 12 Million | ≥ 88% | ≤ 45 | Paper Mill Retention, Inorganic Sludge Dewatering |
| Oubo CPAM-3012 | Medium Cationic | 20% - 40% | 8 - 12 Million | ≥ 88% | ≤ 45 | Municipal Sewage Sludge Centrifuge Decanters |
| Oubo CPAM-5010 | High Cationic | 40% - 60% | 6 - 10 Million | ≥ 89% | ≤ 40 | Textile Dyeing Wastewater & Tannery Sludge Pressing |
| Oubo CPAM-8008 | Ultra-High Cationic | 60% - 80% | 5 - 8 Million | ≥ 90% | ≤ 35 | Chemical/Pharmaceutical Highly Organic Sludge |
Established in 2011 inside the Qingdao Free Trade Zone, China, Oubo Chemical offers unprecedented supply security and chemical engineering expertise.
Our quality management system is strictly certified under ISO9001:2008. Raw materials are sourced directly from premier global chemical giants including SINOPEC and Eni. Every single batch of polyacrylamide undergoes 3 separate mandatory quality checks before release: raw material monomer purity testing, polymerization degree analysis, and final application jar-testing performance verification.
Located directly within the Free Trade Zone of Qingdao, China, Oubo benefits from immediate proximity to Qingdao Port—one of the largest container ports globally. This location guarantees rapid export logistics, continuous availability of bulk shipping containers, streamlined customs clearance, and reduced land transport overheads, allowing us to pass significant cost savings directly to wholesale buyers.
We do not just ship chemicals; we provide end-to-end process optimization. Oubo’s chemical engineering team participates actively in pre-sales analysis, pilot jar testing, product selection, site dosing setup, and ongoing after-sales technical troubleshooting. We partner with clients worldwide to ensure optimal dosage efficiency and minimum operational expenditure.
Engineered solutions tailored specifically for municipal, industrial, paper, oilfield, and mining process requirements.
Essential for municipal sewage treatment, industrial effluent clarification, and activated sludge dewatering across belt presses, centrifuges, and filter presses.
Serves as a wet-end retention aid, drainage promoter, paper strength enhancer, and white water clarifier.
Utilized in Enhanced Oil Recovery (EOR), profile control, plugging agents, and high-performance drilling fluid additives.
Extensively applied in coal tailings dewatering and solid-liquid separation of base metals including gold, silver, iron, copper, and nickel.
Functioning as a dye house effluent flocculant, textile sizing agent, and fabric finishing additive.
Utilized for sugar juice clarification, flotation, and food processing wastewater treatment.
Navigating global environmental mandates with low-residual monomers, green manufacturing pathways, and localized support.
Environmental standards in North America and the EU (REACH, TSCA) strictly regulate residual acrylamide (AM) content due to monomer toxicity concerns. Oubo’s biological enzymatic synthesis guarantees ultra-low residual AM levels (< 0.05% or < 500 ppm), ensuring full international regulatory compliance for safe discharge and handling.
By producing ultra-high molecular weight polyacrylamide, our customers achieve identical flocculation performance with up to 20% lower dosage rates. Lower dosage directly reduces chemical logistics volume, lowers sludge transport fuel consumption via drier cake output, and reduces carbon footprint across municipal and industrial supply chains.
Modern industrial wastewater plants are adopting online viscosity and charge-monitoring sensors. Oubo’s granular dry powders offer exceptional dissolution uniformities, preventing fish-eye gel formations and protecting automated chemical metering pumps from clogs or calibration drifts.
Customized export packaging designed for international moisture protection and shelf-life preservation.
25kg PE/Kraft paper craft bags for re-labeling & OEM distributors.
Factory printed 25kg multi-wall moisture-proof composite bags.
750kg - 1000kg ton bags engineered for heavy mining/oilfield use.
Fumigation-free pallets with heavy plastic film wrapping for ocean shipping.
