Properties
MA/AA is a low molecular weight polyelectrolyte, obtained by the copolymerization of maleic acid and acrylic acid. MA/AA has a strong dispersion of carbonate, with high thermal stability, can be used in harsh conditions such as high temperature of 300°C. MA/AA has good compatibility and synergistic effect with other water treatment chemicals. It also has excellent inhibition effect to the formation of most scales including phosphate.
Storage
Storage in shady room and dry place.
pH of 1% solution
1.20 min
Application
MA/AA can be used in circulating cooling water system, medium or lower pressure boiler and distillation system in which high temperature is usually encountered. It can also be used as chelating agent in textile printing and dyeing industry. MA/AA can be used alone or together with other organic phosphates. When used together, the dosage of 2-10 mg/L is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments.
Appearance
