polyacrylamide for water purification

The anionic PAM is made through the alkali homopolymerization and hydrolysis prior to acrylamide,and through the granulation,drying and grinding. Its apperance is white fine grains or powdery solids. Classification and Performance Index model Molecular weight Degree of hydrolysis% adjustable Solid content% EffectivePH value Residual monomer HYA-1 2000-3000 35-45 ≥89 5-14 ≤0.05 HYA-2 1800-2600 30-40 ≥89 5-14 ≤0.05 HYA-3 1500-2500 25-35 ≥89 5-14 ≤0.05 HYA-4 1000-2000 15-30 ≥89 5-14 ≤0.05 HYA-5 800-2000 10-25 ≥89 5-14 ≤0.05 HYA-6 500-1600 6-20 ≥89 5-14 ≤0.05 Package,Storange and Transportation Packed in 25KG P.P woven bags or paper-plastic bags with PE lined,or as per buyers instructions.In storage and transportation,pay attention to heartproof and moisture-proof . The powdery product will be damped to be caked and will be poor in solubility if exposure to air for long time ,The stacking layer shouldn’t be more than 20layers Shelf life is two years. Application: In The Treatment of Industrial Waste Water Widely used in the treatment of the sewage with suspended grains ,high concentration, positive charges and mid or alkali PH value, the waste water from a iron and steel plant, an electroplating factory and a coal washing works, and metallurgicai waste water.
