Description
Structural formula:
Performance and Applications:
MA/AA It is a low-molecular-weight polyelectrolyte prepared by copolymerizing maleic acid and acrylic acid in a specific ratio. It exhibits strong dispersing effects on carbonates and other substances, and boasts high thermal stability; it can be used in… 300℃ It can be used under harsh conditions such as high temperatures and exhibits excellent compatibility and synergistic effects when combined with other water treatment chemicals.
MA/AA It exhibits excellent inhibitory effects on scale formation, including phosphate-based scale. Thanks to its outstanding scale-inhibiting performance and high-temperature resistance, it is widely used in low-pressure boilers, district heating systems, central air-conditioning systems, and various circulating cooling water systems. It can also be employed as a chelating dispersant in the textile dyeing and printing industry.
