Polyacrylamide is a water-soluble polymer with valuable properties such as flocculation, thickening, shear resistance, resistance reduction and dispersion. These varied properties depend on the derivative ion. As a result, it is widely used in oil extraction, mineral processing, coal washing, metallurgy, chemical industry, paper making, textile, sugar, medicine, environmental protection, building materials, agricultural production and other sectors.
Then how to make Polyacrylamide suitable for use?
First of all, it is important to choose the right model when selecting polyacrylamide. Cationic polyacrylamides are water-soluble linear polymeric organic polymers consisting of cationic monomers and acrylamide copolymers, it is mainly negatively charged colloids during flocculation and has functions such as oil removal, decolourisation, adsorption and adhesion.
Anionic PAM uses the polar groups contained in its molecular chain to adsorb suspended solid particles, bridging them or causing them to
coalesce to form large flocs by charge neutralisation.This allows inter-particle bridging, or the coalescence of particles to form large flocs through charge neutralisation.
Nonionic PAM is a water-soluble polymer. It is mainly used for flocculation and clarification of various industrial wastewater and is more effective under weak acidic conditions.
