Properties and Uses
AA / AMPS to acrylic acid and 2-acrylamido-2-methylpropane sulfonic acid (AMPS) copolymerized. Because the molecular structure contains good scale inhibition and dispersion and strong polar carboxylic acid group, can improve calcium tolerance of water calcium phosphate, calcium carbonate, zinc scale significant scale effect, prevent oxidation iron deposition, especially calcium phosphate scale rate. And excellent dispersion properties. Organic phosphine complex, synergistic effect is obvious. Particularly suitable for high pH, high alkalinity, water high hardness, is to achieve one of the best high concentration scale dispersant operation.
AA / AMPS also be used as textile auxiliaries; pulp and paper system inhibitors.
