Structural Formula:
Performance and Applications
AA/AMPS is copolymerized from acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid (AMPS). Because the molecular structure contains carboxylic acid groups with good scale inhibition and dispersion performance and strong polar sulfonic acid groups, it can improve calcium tolerance, has significant scale inhibition effect on calcium phosphate, calcium carbonate, zinc scale, etc. in water, prevents the deposition of iron oxide, especially has a high scale inhibition rate on calcium phosphate, and has excellent dispersion performance. When compounded with organophosphorus, the synergistic effect is obvious.
AA/AMPS is suitable for water with high pH, high alkalinity and high hardness, and is one of the ideal scale inhibitor dispersants for operation under high concentration cycles.
AA/AMPS can also be used as textile printing and dyeing auxiliaries; scale inhibitor for pulp in papermaking systems.
