Polyacrylamide (CAS 9003-05-8) is a synthetic, water-soluble linear polymer formed through the free-radical polymerization of acrylamide ($CH_2=CH-CONH_2$) monomers. Its functional versatility stems from the high reactivity of its amide side groups, which can be chemically modified to yield varying ionic charges (Anionic, Cationic, Nonionic, and Amphoteric) and tailored molecular weights ranging from 3 Million to over 30 Million Daltons.
Mechanism: Synthesized by copolymerizing acrylamide with acrylic acid or sodium acrylate. APAM introduces negatively charged carboxylate groups ($-\text{COO}^-$) along the polymer backbone.
Primary Function: Operates primarily through bridging flocculation. The extended polymer chains adsorb onto positively charged suspension particles, linking them into large, rapidly settling flocs.
Target Applications: Mineral processing, inorganic effluent clarification, paper dry-strength enhancement, and tertiary Enhanced Oil Recovery (EOR).
Mechanism: Produced by copolymerizing acrylamide with cationic monomers such as DAC (Dimethylaminoethyl Acrylate Methyl Chloride) or ADAM.
Primary Function: Governed by charge neutralization followed by bridging. It neutralizes the negative zeta-potential on organic suspensions, collapsing electrostatic repulsion barriers.
Target Applications: Municipal sewage sludge dewatering, belt filter press/centrifuge operations, oily wastewater separation, and textile dyeing effluent treatment.
Mechanism: Homopolymerized pure acrylamide featuring neutral amide functional groups ($-\text{CONH}_2$) without ionic charge sites.
Primary Function: Relies on hydrogen bonding between the amide groups and suspended organic/inorganic substrates under acidic or high-salinity conditions.
Target Applications: Acidic industrial wastewater flocculation, mineral tailings leaching, soil conditioning, and oilfield drilling fluid viscosification.
Customized polymer formulations tailored for maximum solid-liquid separation kinetics across key industries.
As environmental regulations tighten globally, effective sludge dewatering and effluent clarification are critical. In municipal sludge handling, our high charge-density Cationic Polyacrylamide (CPAM) achieves superior cake dryness (>25% solid content) on belt presses and decanter centrifuges, while drastically lowering chemical dosage requirements.
In mature oil fields, ultra-high molecular weight APAM acts as a mobility control agent during polymer flooding, increasing sweep efficiency. In drilling operations, Oubo PAM formulations serve as shale inhibitors, viscosifiers, and fluid-loss additives capable of withstanding high shear stress and geothermal temperatures.
Oubo’s specialized PAM series acts as dry/wet strength agents, retention aids, and drainage accelerators. By neutralizing anionic trash in the wet-end process and forming ionic bonds with cellulose fibers, our polymers improve paper sheet formation while retaining fine fillers and fibers.
In hydrometallurgy and coal washing, efficient liquid-solid separation is key to water recycle circuits. Oubo’s APAM and NPAM lines accelerate tailings thickening, clarifying process water for immediate reuse and enabling fast centrifuge dewatering of gold, copper, iron, and coal slurry.
Engineered to global shipping standards with customized OEM/ODM packaging options.
Pioneering bio-catalytic synthesis pathways and micro-emulsion technologies for carbon-neutral industrial chemistry.
Replacing traditional copper-catalyzed nitrile hydration with microbiological nitrile hydratase enzymes. Yields 99.9% pure monomer with zero copper residue and 40% reduced carbon emissions.
Developing stable polyacrylamide polymers exceeding 30 Million Daltons for deep-well fracturing and ultra-low dosage mine tailings thickening.
Formulating rapid-dissolving liquid emulsions that invert within seconds upon water addition, eliminating powder dust hazard and shortening hydration aging times by 80%.
