Effect Principle 1) Principle flocculation: PAM for flocculation, the flocs are species with surface properties, in particular the zeta potential, viscosity, PH value and the turbidity of the suspension is related to the particle surface zeta potential, particle polymerization of Cause addition of surface opposite charge PAM, make the move to reduce the potential and cohesion. 2) adsorption bridging: PAM molecular chain immobilized on the surface of different particles, each bridge is formed between the polymer particles, the particles form aggregates and settle. 3) Surface: various polar groups adsorbed particles PAM molecule. 4) enhancement: PAM molecular chain and dispersed by seed mechanical, physical, chemical and so on, will be involved with the dispersed phase to form a network.
