马来酸-丙烯酸共聚物（Copolymer of Maleic and Acylic Acid，MA/AA）是一种低分子量的聚电解质，由马来酸与丙烯酸按一定比例共聚制得，MA/AA对碳酸盐等具有很强的分散作用，热稳定性高，可在300℃高温等恶劣条件下使用，与其它水处理药剂具有良好的相容性和协同增效作用。对包括磷酸盐在内的水垢的生成具有良好的抑制作用。由于MA/AA阻垢性能和耐高温性能优异，因此广泛用于低压锅炉、集中采暖、中央空调及各类循环冷却水系统中。MA/AA也可用于纺织印染行业作螯合分散剂使用。

符合GB /T 2229-2018

MA/AA可在温度较高的循环水系统或低压锅炉、蒸馏系统中使用。与其他有机磷酸盐复配使用，用量一般在2～10mg/L。

MA/AA作纺织印染助剂及助洗剂的用量由试验确定。

MA/AA 为酸性，应避免与皮肤、眼睛等接触，接触后应用大量水冲洗。

MA/AA 为塑料桶包装，每桶25Kg或200kg。贮存期十二个月。

Copolymer of Maleic and Acylic Acid (MA/AA)

【CAS】26677-99-6

Properties:MA/AA is a low molecular weight polyelectrolyte, a copolymer of maleic anhydride and acrylic acid. It has good dispersant performance against carbonate and scale inhibition for phosphate. it has good thermal stability, can be used under high temperature (300℃). MA/AA has good compatibility when used together with other agents. MA/AA is widely used in low-pressure boiler, centralized heating, centralized air-conditioner and circulating cool system. It can also be used as chelating dispersants in woven and dyeing fields.

Specification:

Usage:MA/AA is used in circulating cool water system, medium or lower pressure boiler and distillation system in which high temperature is usually encountered. MA/AA can be used alone or together with other organic phosphates. When used together, the dosage of 2-10mg/L is preferred. The dosage for use as woven & dyeing and accessory detergent should be determined by experiments.

Package and Storage:Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.

Package and Storage:Acidity, Avoid contact with eye and skin, once contacted, flush with water.
