1.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. 2.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 |
3.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. 4.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.
