Polyacrylamid

Use characteristic 1) flocculation sex: PAM can make the suspended material through electric neutralization, bridging adsorption effect, since flocculation effect. 2) agglutinate sex: can pass the mechanical, physical and chemical action, on bonding effect. 3) the resistance reduction sex: PAM can effectively reduce fluid frictional resistance, adding water trace PAM can dray reduction of 50-80 percent. 4) thickening sex: in a neutral and PAM acidity conditions are thickening functions, while PH in 10 above PAM easy hydrolysis. A half mesh structure, thickening will be more apparent. PAM action principle profile 1) flocculation mechanism: used for flocculation PAM, and BeiXu coagulation species of surface properties, especially the dynamic potential, viscosity, turbidity and suspension PH value relevant, particle surface of dynamic potential, is particles inhibitor reasons to join the surface charge opposite PAM, can make the move potential reduce and cohesion. 2) adsorption bridging PAM molecular chains fixed in: different particle on the surface, the particles formed between polymer bridge, make granules form micelles and settlement. 3) the surface of PAM molecules adsorbed: various polargroup particle adsorption. 4) enhancing effect: PAM molecular chain and the dispersed phase through various machinery, physics, chemistry, etc function, will the dispersed phase implicated in together, grid formation, thus enhanced role plays.
