1976年，伊利诺伊州卡本代尔市开始使用商业磷酸盐化合物进行腐蚀控制，而不是使用苛性钠作为氢氧化钠进行pH值控制。本文讨论了使用磷酸盐化合物的优点，包括降低化学成本，改善安全条件，减少机械和设备的维护。试片测试、corrator探针和水分析的结果证实了磷酸盐抑制剂的有效性。包括参考，表格。

In 1976 the city of Carbondale, Illinois began using a commercial phosphate compound for corrosion control rather than caustic soda as sodium hydroxide for pH control. This article discusses the advantages of using the phosphate compound, including decreased chemical costs, improved safety conditions, and reduced maintenance of machinery and equipment. Results from coupon tests, a corrator probe, and water analyses confirmed the effectiveness of the phosphate inhibitor. Includes reference, table.
