Polyacrylamide polymer is, simply called PAM, a water- soluble high polymer and widely used in petroleum, paper-making, metallurgical, textile, chemical and environment protection fields. There are three categories of anionic, cationic and non-ionic type.
Polyacrylic acide(Anionic powder) is high molecular weight polymer with anionic charge, used for industrial and potable water treatment, paper mills and mining industry.
CAS number for PAM: 9003-05-8
Polyacrylamide Polymer Functional principle
Flocculation Mechanism: Adsorbing suspension particles, polymer chains entangle and cross-link each other to form bridging, and make flocculation structure enlarge and thicken, and has the functions of surface adsorption and electric neutralization. Reinforcing Mechanism: Polyacrylamide(PAM) molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.
