PAM for improving water quality

Polyacrylamide(PAM)
Usage:Water Treatment Chemical
High molecular weight



Polyacrylamide(PAM)
Use properties
1) : flocculation PAM can make the suspended material through electric bridge, adsorption, flocculation effect since.
2) springiness: mechanical, through the role of physical and chemical, adhesive.
3) reduction of PAM: can effectively reduce the friction resistance, water flow can trace PAM resistance reduction of 50-80.
4) thickening of PAM: in neutral and acid conditions were, when thickening in 10 PH PAM above to hydrolysis. A half mesh structure, increase
Thick will be more apparent.

PAM principle of introduction
1) flocculation mechanism for flocculation PAM: when BeiXu and surface properties of species, especially the dynamic potential, viscosity, turbidity and suspension PH value, particle surface of potential, is the reason to join polymerization particle surface charge instead PAM, can reduce hydraulic. And potentials,
PAM: 2) adsorption chain Bridges in different particles on the surface, the granular form between polymer bridge, make granules form micelles and settlement.
PAM: 3) surface adsorption of molecules of adsorption polargroup particles.
PAM: 4) improved chain and computed by various machinery, physics, chemistry, etc, will be dispersed phase involved together, forming mesh, thus enhanced role plays.
PAM is water-soluble polymer, insoluble in most organic solvents, good flocculation sex, can reduce the friction resistance between liquid, according to the properties of ionic, can be divided into the points, anionic, cationic and gender type four types.
