Properties: AA/AMPS is the copolymer of acrylic acid and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS). Due to including carboxylic group (scale inhibition and dispersion) and sulfonic acid group (strong polarity) in this copolymer, AA/AMPS has high calcium tolerance and good scale inhibition for calcium phosphate, calcium carbonate and zinc scale. When built with organophosphines, the synergic effect is obvious. AA/AMPS is suitable to be used in water quality of high pH and high alkaline, it is one of the ideal scale inhibitor and dispersant on high concentration index. Specification: Conform to HG/T3642-1999 items index Appearance Colorless or light yellow viscous liquid Solid content % ≥ 30 40 Free monomer (as AA)% ≤ 0.5 0.8 Density (20℃)g/cm3 ≥ 1.05 1.15 Viscosity (30℃) dl/g 0.055 - 0.100 - pH(1% solution) ≤ 3.0 3.5 - 4.5 Application range: AA/AMPS can be used as scale inhibitor and dispersant in open circulating cool water system, oilfield refill water system, metallurgy system and iron & steel plants to prevent sediment of ferric oxide. When built with organophosphorines and zinc salt, the suitable pH value is 7.0~9.5. AA/AMPS can also be used as dyeing auxiliaries for textile. Package and Storage: Normally In 25kg,200 kg or 250kg net Plastic Drum, or packing as customers’ request.Storage for ten months in room shady and dry place.
