馬來酸-丙烯酸共聚物

馬來酸-丙烯酸共聚物

馬來酸-丙烯酸共聚物(Copolymer of Maleic and Acylic Acid,MA/AA)是一種低分子量的聚電解質,由馬來酸與丙烯酸按一定比例共聚製得,MA/AA對碳酸鹽等具有很強的分散作用熱穩定性高,可在300℃高溫等惡劣條件下使用,與其它水處理藥劑具有良好的相容性和協同增效作用。對包括磷酸鹽在內的水垢的生成具有良好的抑制作用。由於MA/AA阻垢性能和耐高溫性能優異,因此廣泛用於低壓鍋爐、集中採暖、中央空調及各類循環冷卻水系統中。MA/AA也可用於紡織印染行業作螯合分散劑使用。

英文介紹

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.
