新型抑垢阻沉淀剂的制备与阻垢效果的研究

Preparation of a New Scale Inhibitor-Antiprecipitantand It's Scale Inhibiting Efficiency

为提高聚丙烯酸盐类高分子水处理剂的功能，特别是加强抑垢及阻沉淀效果，作者制备了添加单一或混合型有机络合剂的ＡＡ／ＡＭ共聚物。模拟蒸发实验表明：加入添加有混合型有机络合剂的ＡＡ／ＡＭ共聚物１２ｐｐｍ（真实固含量）具有９６．６％～９７．８％阻垢率（以Ｃａ２＋计）。

crylic Acid/Acrylamine copolymer adding single or mixed organic complexants was prepared in order to improve the behavior of the copolymer in water treatment specially in inhibiting scale and antiprecipitating. The conditions of reaction and operating process were studied. IR, solid contents and characteristic viscosities of the products were determined. The results in a simulated evaporative test indicated that the percentage of scale (as Ca2+) inhibition is 966～978 when 12ppm(real solid)AA/AM copolymer adding mixed organic complexants was used.
