2026-04-14 10:08:33
Anionic Polyacrylamide(APAM)is a water-soluble high-molecular polymer with negative charge groups on its molecular chain.It is widely used as a flocculant,thickener,binder,filtration aid,and rheology modifier in various industrial fields due to its high molecular weight,good water solubility,and strong adsorption bridging ability.
Main Applications
Wastewater Treatment
It is mainly used for flocculation and sedimentation of industrial wastewater,municipal sewage,and river water treatment.It can effectively adsorb suspended particles,aggregate them into large flocs,speed up solid-liquid separation,and reduce turbidity and COD.
Mining&Mineral Processing
Used for ore slurry concentration,tailings dewatering,and mineral flocculation.It improves solid-liquid separation efficiency,reduces fine ore loss,and speeds up filtration and sedimentation.
Oil&Gas Drilling
Applied in drilling fluids as a fluid loss controller,viscosity modifier,and shale stabilizer.It enhances mud carrying capacity,stabilizes the wellbore,and reduces filtration loss.
Paper Making Industry
Used as a retention and drainage aid,surface sizing agent,and paper strengthening agent.It improves fiber retention rate,accelerates dehydration on the paper machine,and enhances paper strength and smoothness.
Construction&Building Materials
Acts as a thickener,water-retaining agent,and binder in mortar,concrete,and grouting materials.It improves workability,reduces segregation,and enhances bonding strength.
Textile&Printing Industry
Used as a textile printing and dyeing thickener and sizing agent to improve color uniformity and fabric surface smoothness.
