Anti-scaling corrosion inhibitors (LQ - 676)

1. With advanced phosphorus acid, sulfonates for main components, copolymer has excellent corrosion inhibition;
2. The calci
PAM (PAM) abbreviation Polyacrylamide, is a linear polymers, the application of water-soluble polymer compound is one of the most extensive varieties, PAM and its derivatives can be used as effective flocculating agent, thickener, fortifier, and liquid friction reduction agent, since 1974 introduced to China is widely used in water treatment, papermaking, petroleum, coal, mining and metallurgy, geology, textile, building and industry departments.
PAM is a linear polymer, it is soluble in water, hardly soluble in benzene, ether and ester, acetone general organic solvent, and its solution nearly transparent viscous liquid, belong to the dangerous goods, non-toxic, no corrosive, solid PAM has hygroscopic, hygrosc opicity with ion degrees increases, PAM good thermal stability; Heated to 100 °C good stability in 150 °C above, but can decompose produce nitrogen, when at the molecular between imine function and insoluble in water, density (g) milliliter 23 °C 1.302. The glass transition temperature of 153 °C, PAM showed in stress under the action of non-newtonian fluid.
use properties
1) flocculation sex: PAM can make suspension material through electric neutralized, bridging adsorption effect, up flocculation effect.
2) agglutinate sex: can through mechanical, physical, chemical, up the role of adhesive role.
3) drop negative: PAM can effectively reduce the friction resistance, water flow trace PAM can join the resistance reduction 50-80 percent.
4) thickening sex: PAM in neutral and acid conditions are thickening functions, while PH in 10 °C above PAM easy hydrolysis. When a half reticulation, thickening will be more apparent.
PAM acti on principle profile
1) flocculation mechanism: PAM used for flocculation, and surface properties BeiXu coagulation species, especially of dynamic potential, viscosity, turbidity and suspension PH value relevant, particle surface dynamic potential, is the reason to join particle inhibitor of surface charge instead PAM, can reduce and condensing hydraulic potential.
2) PAM molecular chain adsorption Bridges: fixed in different particle surface, each particle polymer bridge formed between, grain to form micelles and settlement.
3) on the surface of PAM molecular adsorption: all kinds of adsorption polargroup particles.
4) enhancing effect: PAM molecular chain and the dispersed phase through various machinery, physics, chemistry, etc, will the dispersed phase lead role in together, grid formation, thus enhanced role plays.
