Oubo Chemical Co., Ltd was established in 2011, located in the Free Trade Zone of Qingdao, China. The Quality Control system of O'brien is strict and comprehensive. Over the past decade, our business growth rate has sustained 10% per year. Qingdao Oubo Chemical Co., Ltd is highly committed to quality, service, and pays paramount attention to environmental sustainability during polymer production and global oilfield application.
We specialize in supplying Cationic Polyacrylamide, Anionic Polyacrylamide, and Nonionic Polyacrylamide. Our advanced synthesis equipment and elite technical personnel ensure all products and field services remain in optimal performance order. Certified by ISO9001:2008, Oubo stands firmly behind every chemical shipment dispatched globally.
Understanding the molecular weight distribution, enzymatic polymerization, and hydrogen bonding mechanisms in extreme downhole environments.
Unlike conventional chemical hydrolysis, Oubo utilizes patented biological enzymatic methods to convert acrylonitrile into monomer acrylamide. This biological pathway minimizes chemical impurities, produces ultra-high molecular weight chains (up to 12-15 Million Daltons), and keeps free monomer residuals strictly under 0.05%.
Nonionic Polyacrylamide (NPAM) is synthesized as a homopolymer of acrylamide with zero net ionic charge. Because it lacks electrical charge along its backbone, NPAM is virtually insensitive to high salinity, divalent calcium (Ca²⁺), and magnesium (Mg²⁺) ions, preventing polymer precipitation in harsh brine formations.
NPAM induces bridging flocculation and rheological thickening via strong hydrogen bonding between its abundant amide groups (-CONH₂) and hydroxyl surface sites of suspended solids, clay minerals, or silica particles. This creates durable micro-flocs capable of enduring elevated shear stress.
| Polymer Type | Ionic Charge Degree | Molecular Weight (MW) | Salt Tolerance (Brine) | Primary Oilfield / Industrial Role |
|---|---|---|---|---|
| Nonionic PAM (NPAM) | Neutral (0 - 2%) | 3 Million - 15 Million | Exceptional (Unaffected by Ca²⁺/Mg²⁺) | Acidic wastewater flocculation, HT/HS drilling fluid loss reduction, EOR sweep efficiency |
| Anionic PAM (APAM) | Negative (5% - 80%) | 5 Million - 25 Million | Moderate (Prone to divalent metal precipitation) | Polymer flooding, profile control, clay stabilization, neutral/alkaline sludge dewatering |
| Cationic PAM (CPAM) | Positive (5% - 80%) | 4 Million - 12 Million | Low to Moderate | Organic sludge dewatering, textile effluent treatment, paper retention & drainage aid |
Tailored polyacrylamide chemistry addressing complex challenges across oil extraction, wastewater purification, paper manufacturing, and heavy metallurgy.
Enhanced Oil Recovery (EOR) & Drilling Fluid Rheology
NPAM acts as a premier fluid loss additive, friction reducer, and shale inhibitor in oil drilling muds. In secondary and tertiary enhanced oil recovery (EOR), NPAM increases mobility control ratio, improves volumetric sweep efficiency, and prevents water breakthrough in heterogeneous reservoirs with extreme thermal and saline profiles.
Municipal Sewage & Acidic Effluent Clarification
Nonionic polyacrylamide excels in solid-liquid separation processes where effluent pH is acidic (pH < 5.0). It accelerates settling rates in sedimentation tanks, enhances water clarification, and significantly reduces total suspended solids (TSS) across chemical processing and electroplating industries.
Dry Strength, Retention & Fiber Dispersant
Used as a retention agent, drainage aid, and dispersant, NPAM enhances inter-fiber hydrogen bonding, increasing paper burst strength, tensile durability, and filler retention while accelerating wet-end dewatering speeds on modern high-speed paper machines.
Mineral Separation & Tailings Management
In mineral slurry processing, NPAM binds to fine mineral particles of gold, silver, copper, iron, and coal tailings. It speeds up thickener sedimentation rates, ensures rapid filtration, and facilitates eco-friendly tailing pond water recycling.
Combining world-class raw material sourcing, automated polymer synthesis lines, and rigorous triple-stage QA/QC protocols in Qingdao FTZ.
To guarantee unyielding batch-to-batch consistency, Oubo partners directly with global energy and chemical giants, including SINOPEC and Eni. Primary monomers undergo strict HPLC assay verification before entering continuous polymerization reactors.
Every production lot is subjected to three consecutive quality checks: incoming monomer purity, in-line polymerization viscosity tracking, and final dry granule particle size/dissolution testing in accordance with ISO 9001:2008 standards.
Our proprietary biological enzyme catalyst route operates at ambient temperatures, reducing carbon emissions by up to 35% compared to thermal copper-catalytic methods, while keeping environmental impact to an absolute minimum.
Advancing thermo-tolerant chemical structures and eco-compatible polymers for modern deepwater and high-temperature oilfields.
Developing modified nonionic polymers incorporated with temperature-resistant monomers (such as AMPS/NVP) capable of sustaining long-term viscosity in reservoir fluids exceeding 120°C (248°F) without thermal degradation.
Next-generation micro-porous polymer granules engineered to dissolve within 20–30 minutes (compared to traditional 60+ minutes dissolution time), preventing fish-eye formation and operational downtime at offshore oil rigs.
