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 active pointsadsorbed on the suspended particles in the solution, the formation of particlesbetween the bridge, thus accelerating the settlement of suspended particles. Asthe flocculant sodium polyacrylate its molecular weight up to several million,the commercial form of yellow viscous liquid, solid content or up to 8% Xu, thecorresponding 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.
Papermaking Chemicals
Papermaking chemicals Papermaking coatingsas dispersants. The most suitable relative molecular mass is 2000-3000. Thecommodity form is generally 30% or 42% solids. The viscosity is less than 600mPa.s. Appearance colorless and transparent to amber liquid. The pH is between6-9.
