Matters needing attention

1 configure the concentration

Anionic, non-ionic due to the high molecular weight, strong viscosity, anion concentration standard of 1 per thousand (according to adjust the turbidity concentrations. High turbidity and decreased concentration; low turbidity, can increase the dose, but does not change its concentration was good, smooth or easy piping).

2 dissolution vessel

Dissolution action in plastic, ceramic, stainless steel mixing tanks. Because PAM chains in solution is a random coil, at the time of preparation and dissolution, in some of the online community, coils and large and plump, easily intertwine with Crosslinking between the coils, from the appearance of a certain viscosity. If due to the high-speed rotation of the impeller of a centrifugal pump structure of macromolecular coil deformation part separated from the Middle, smaller, cross-linking between the coils is destroyed, viscosity, reduced performance.

3 the mixing process

PAM chain in solution of shear force leads to molecular chain degradation, affecting performance, dissolve dilute PAM should as far as possible to reduce mixing time stirring reduced agitation speed should be controlled at 50-250 rpm, not too fast. PAM solution, dosing should be avoid strong mechanical stirring; conveying PAM solution, line thicker, less tip and pipe, pump use Mono pump or diaphragm pump, rather than selection of centrifugal pumps.
