馬來酸-丙烯酸共聚物
鎖定
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℃高温等惡劣條件下使用，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阻垢性能和耐高温性能優異，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。
馬來酸-丙烯酸共聚物抽取通過氧化二苯甲酰為引發劑，以馬來酸酐為主，加入少量的丙烯酸共聚後，經水分解制成

馬來酸-丙烯酸共聚物英文介紹
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.
Specification:
items | Water treatment agent | Accessory detergent |
Appearance | Clear brown liquid | amber transparent liquid |
Solid content % | 48 min | 50 min |
Free monomer (MA) % | 9.0 max | 5.0 max |
Density （20℃）g/cm | 1.18 min | 1.18min |
pH（1% solution） | 2.0~3.0 | 2.0±1.0 |
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.
