Explore our top-tier industrial polyacrylamide grades engineered for maximum flocculation efficiency, water clarification, and process optimization.
A comprehensive analysis of polymer chemistry, charge dynamics, and high-efficiency solid-liquid separation science.
Anionic Polyacrylamide (APAM) is a linear, water-soluble high-molecular synthetic polymer produced through the copolymerization of acrylamide (AM) monomer with functional anionic co-monomers, primarily acrylic acid or sodium acrylate ($CH_2=CH-COONa$). Characterized by its high molecular weight ranging from 5 Million to upwards of 25 Million Daltons and a controllable degree of hydrolysis (charge density ranging from 10% to 60%), APAM serves as an essential chemical reagent across global process industries.
The fundamental physics of APAM performance hinges upon two main mechanisms: Charge Neutralization and Interparticle Polymer Bridging. When introduced into aqueous suspensions containing positively charged inorganic suspended solids, the negatively charged carboxylate groups ($-COO^-$) along the extended macromolecular chain interact electrostatically with particle surfaces. Concurrently, the long-chain amide backbone extends into the fluid medium, adsorbing onto multiple suspended particles simultaneously to form massive, rapidly settling micro-flocs and macro-flocs.
Ranging from 6 Million to 25 Million Daltons. Higher molecular weight polymers create robust physical bridges across vast liquid distances, ideal for mine tailings thickening, sediment clarification, and drag reduction in fluid transfer pipelines.
Tailored from 10% (low anionicity) to 60% (high anionicity). Dictates the electrostatic binding intensity with mineral substrates, clay platelets, and heavy metal hydroxides across varying pH environments (pH 4 to 12).
Established in 2011 within the state-level Strategic Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd (O'brien brand) has developed into a premier world-class synthesis enterprise for water-soluble polymers. Engineered around a rigorous quality control framework, Oubo has sustained an annual business growth rate of over 10% for the past decade, achieving an annual polyacrylamide production capacity breaking through 50,000 Metric Tons in 2018.
Our manufacturing facilities operate under strict compliance with the ISO9001:2008 Quality Management System certification. By utilizing advanced biological enzymatic monomer synthesis pathways— reinvesting over €2 Million annually into technical formulation research—Oubo delivers high-purity PAM products with ultra-low residual acrylamide monomer (<0.05%), exceptional thermal stability, and accelerated dissolution kinetics.
From heavy municipal sewage treatment to high-salinity oilfield polymer flooding, discover how Oubo Anionic Polyacrylamide optimizes process performance worldwide.
Functions as a primary coagulant aid and flocculant for municipal wastewater clarifiers, industrial effluent treatment, and inorganic sludge dewatering. Ideal for neutral-to-alkaline aqueous systems, accelerating solid sedimentation rates while reducing chemical dosage costs by up to 30% compared to inorganic alum or iron salts alone.
Extensively deployed in Enhanced Oil Recovery (EOR) as a mobility control polymer flood agent. Provides superior shear resistance, thermal tolerance in high-salinity reservoirs, profile modification, hydraulic fracturing fluid thickening, and shale hydration inhibition in drilling mud systems.
Essential for coal slurry washing, alumina red mud clarification (Bayer Process), gold and copper hydrometallurgical tailings thickening, and centrifugal sludge filtration. Increases overflow water clarity for zero-liquid-discharge (ZLD) plant recycling.
Acts as an effective retention aid, drainage promoter, dry/wet strength agent, and anionic garbage scavenger. Enhances fine fiber and filler retention, improves sheet formation uniformity, and recovers valuable suspended fibers from paper machine white water.
Used as a synthetic textile warp sizing agent for smooth yarn abrasion resistance, fabric finishing chemical, and highly efficient flocculant for textile dyeing wastewater decolorization and COD/BOD parameter reduction.
Formulated for food-grade juice clarification, sugarcane extract flotation, sugar syrup filtration, and organic wastewater treatment in citric acid, starch, and vegetable protein extraction facilities.
1. Paper Retention, Drainage, and Anionic Trash Capture:
In modern high-speed paper machines, the addition of Oubo Anionic Polyacrylamide as a wet-end chemical dramatically balances slurry wet chemistry. APAM interacts with cationic coagulants or dual polymer systems to bind micro-fibers, titanium dioxide ($TiO_2$), and calcium carbonate ($CaCO_3$) fillers. This charge balance reduces anionic garbage interference, preventing felt blinding and improving wire dewatering velocity by 15-25%.
2. Oilfield Hydraulic Fracturing & Polymer Flooding:
In tertiary oil recovery (EOR), maintaining sweep efficiency requires injected water to match reservoir rock permeability without experiencing severe viscosity degradation. Oubo's high-molecular weight APAM creates a viscoelastic aqueous plug. Under high temperature and shear stress, the specialized branched structure resists mechanical degradation, effectively sweeping stranded crude oil from low-permeability subterranean strata.
3. Coal Tailings & Heavy Ore Clarification:
Coal preparation plants deal with dense black water containing ultra-fine clay suspensions. Adding APAM at concentrations as low as 1 to 5 ppm induces rapid agglomeration into dense flocs, allowing thickeners to produce sparkling clear supernatant water for reuse in closed-loop washing circuits, eliminating environmental discharge liability.
Oubo supplies a complete family of PAM products tailored to specific ionic requirements, pH ranges, and substrate charges.
Positively charged copolymer ideal for organic sludge dewatering, municipal waste, and acidic pulp treatment.
Negatively charged, high molecular weight polymer for mineral solids, inorganic wastewater, and EOR flooding.
Neutral polymer designed for acidic wastewater conditions, soil conservation, and specialized mineral leach slurry.
