Property and Uses
MA/AA is a low molecular weight polyelectrolyte copolymerized from maleic acid and acrylic acid in a certain ratio. MA/AA has strong dispersing effects on carbonates and other chemicals, high thermal stability, and can be used under harsh conditions such as 300°C. It has good compatibility and synergistic effects with other water treatment agents. It effectively inhibits the formation of scale including phosphates. Due to the excellent scale resistance and high-temperature resistance of MA/AA, it is widely used in low-pressure boilers, centralized heating, central air conditioning, and various circulating cooling water systems. MA/AA can also be used as a chelating dispersant in the textile printing and dyeing industry.
