1.Performance and usage
AA/AMPS is a copolymer of acrylic acid and 2-acrylamide-2-methylpropanesulfonic acid (AMPS). Because its molecular structure contains carboxylic acid groups with good scale-inhibiting and dispersing properties and highly polar sulfonic acid groups, it can improve calcium tolerance and has a significant scale-inhibiting effect on calcium phosphate, calcium carbonate, zinc scale etc.scales in water, it can prevent the deposition of iron oxide, especially has a high scale inhibition rate on calcium phosphate. And it has excellent dispersion performance. Compounded with organic phosphine, the synergistic effect is obvious.
AA/AMPS is suitable for high pH, high alkalinity and high hardness water, it is one of the most ideal scale inhibitor and dispersants to achieve high concentration multiple operations.
AA/AMPS can also be used as textile printing and dyeing auxiliaries; scale inhibitor for pulp in papermaking systems.
