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.

2

Reinforcing Mechanism:

PAM molecule chain and dispersed phase form bridging bond, ion bond and covalent bond to increase combination strength.
