Keyuan superfine polyacrylamide

Polyacrylamide (PHPA) is a high molecular weight aqueous solution that controls fluid loss and increases viscosity
25kg/bag


PAM
Use properties
1) flocculation sex: polyacrylamide can make the suspended material through electric bridge, adsorption, flocculation effect since.
2) springiness, PAM can through mechanical and physical and chemical bonding effect and function.
3) dray reduction sex: polyacrylamide can effectively reduce the friction resistance, water flow can trace PAM resistance reduction of 50-80.
4) thickening sex: polyacrylamide in neutral and acid conditions were, when thickening in 10 ° above PH PAM easy hydrolysis. A half mesh structure, thickening will more apparent.
PAM principle of introduction
1) flocculation mechanism: polyacrylamide for flocculation, 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,
2) adsorption of polyacrylamide molecular chain Bridges: fixed in different particles on the surface, the granular form between polymer bridge, make granules form micelles and settlement.
3) surface adsorption of molecular polyacrylamide: all kinds of adsorption polargroup particles.
4) enhancing effect: the polyacrylamide with computed by molecular chain mechanical, physics, chemistry, etc, will be dispersed phase involved together, forming mesh, thus enhanced role plays.
