Polyacrylamide Polymer

The potential on the surface of particles is the reason why particles are inhibited by adding PAM with opposite surface charge, which can reduce the potential and agglomerate.


Product Introduction

Polyacrylamide (PAM) is a water-soluble polymer, insoluble in most organic solvents, has good flocculation, can reduce friction resistance between liquids, according to ionic characteristics can be divided into non-ionic polyacrylamide, anionic polyacrylamide, cationic polyacrylamide and amphoteric polyacrylamide.

Brief principle introduction of PAM

(1) Principle of flocculation: When PAM is used in flocculation, it is related to the surface properties of flocculated species, especially the potential, viscosity, turbidity and PH value of suspension. The potential on the surface of particles is the reason why particles are inhibited by adding PAM with opposite surface charge, which can reduce the potential and agglomerate.

(2) Adsorption bridging: PAM molecular chains are fixed on the surface of different particles, and polymer bridges are formed between the particles, which make the particles form aggregates and settle down.

(3) Surface adsorption: Various adsorption of polar group particles on PAM molecule.

(4) Enhancement: PAM molecular chains and dispersed phases, through various mechanical, physical, chemical and other actions, connect dispersed phases together to form a network, thus playing an enhancement role.
