Anionic polyacrylamide is a water-soluble linear polymer with high degree of polymerization. It has flocculation, thickening, shear and resistance reduction properties. Dispersion and other valuable properties. Anionic polyacrylamide although the water surface tension reduction is very small, but the molecule has active groups, adsorbed on the interface, can change the interface state. Its cool amine group (CONH2) and many substances affinity, adsorption to form hydrogen bonds, which can make it in the adsorption of particles of the bridge, so that several or even dozens of particles connected together, can promote colloidal particles gathered into large flocculent, accelerate the settlement of particles in the suspension, accelerate solution clarification, promote filtration and other effects.
