摘要： This invention discloses a method of improving the constitution of boiler water by adding thereto an effective amount of a copper transport agent which is either rubeanic acid or a low molecular weight polymer of polypiperazine methyl-para-hydroxysulfonic acid or polypiperazine methyl-para-hydroxybenzoic acid. The copper transport agent satisfactorily separates the copper from iron, calcium, magnesium and other heavy metals with a high degree of selectivity. The chelant may be added in a ratio of 100/1 to 10/1 chelant/copper and an advantageous ratio in the case of the polymer is 50/1 ppm active polymer to 1 ppm Cu. The chelants, which form a soluble chelate with Cu, is capable of removing Cu through boiler blowdown in an operating, layup or cleanup boiler. This adds an anti-corrosion factor to the galvanized boiler corrosion.
摘要翻译：本发明公开了一种通过添加有效量的铜运输剂来提高锅炉水的构成的方法，铜运输剂是无机硼酸或聚哌嗪甲基对羟基磺酸或聚哌嗪甲基对羟基苯甲酸的低分子量聚合物。铜输送剂以高选择性令人满意地将铜与铁，钙，镁和其他重金属分离。螯合剂可以以100/1至10/1的螯合剂/铜的比例加入，并且在聚合物的情况下的有效比例为50/1ppm的活性聚合物与1ppm的Cu。与Cu形成可溶性螯合物的螯合剂能够通过锅炉排放在操作，上铺或清理锅炉中除去Cu。这为镀锌锅炉腐蚀增加了防腐蚀因素。
