摘要: Methods are provided to inhibit corrosion of metals in contact with aqueous systems such as cooling water systems. In accordance with the methods, a hydroxyacid compound and orthophosphates are used to treat the system. Additionally, an adjuvant including poly(epoxysuccinic acids), an additional hydroxy acid, and a polycarboxylic acid, may be added to the system water.
摘要翻译: 提供了用于抑制与水系统如冷却水系统接触的金属腐蚀的方法。 根据该方法,使用羟基酸化合物和正磷酸盐来处理该体系。 另外,可以向系统水中加入包括聚(环氧琥珀酸),另外的羟基酸和多元羧酸的佐剂。
