Polyacrylic acid sodium is a matureindustrial products, there are industry standards. The standard number is: HG /T2838-2010. Standard product appearance is colorless to yellow liquid, solidcontent greater than or equal to 30%.
High relative molecular mass forflocculants.
Water treatment agent - flocculant
Polyacrylic acid sodium is a linear,soluble polymer compounds, the molecular chain of the carboxyl group due toelectrostatic repulsion. So that the polymer chain stretches around, causingthe adsorption of functional groups exposed to the surface. As these activepoints adsorbed on the suspended particles in the solution, the formation ofparticles between the bridge, thus accelerating the settlement of suspendedparticles. As the flocculant sodium polyacrylate its molecular weight up toseveral million, the commercial form of yellow viscous liquid, solid content orup to 8% Xu, the corresponding intrinsic viscosity η ≥ 3.40.
Sodium polyacrylate flocculant isparticularly suitable for caustic soda and soda ash industry, salt refining,alumina production of red mud sedimentation separation, monosodium glutamatewastewater protein recovery and sugar and other industries of polymermaterials.
