【摘要】 采用ＨＣｌ－ＩＭＣ－ＮＨ４Ｆ 体系，对模拟锅炉进行化学清洗，当ＨＣｌ 质量分数为５％，ＩＭＣ－５质量分数为０．３％，ＮＨ４Ｆ 浓度为３　ｇ／Ｌ，温度为６０￣８０℃时，清洗５　ｈ，缓蚀效率达９９％ 以上。更多还原

【Abstract】 The systemof HCl-IMC-NH4F is adopted to clean the simulated boiler.When thevolume fraction of hydrochloric acid is 5% , the volume fraction of IMC-5 is 0.3% and the concentration of ammonium fluoride is 3 g/L, the corrosion-preventing efficiency can reach 99% after the boiler is dealt with for 5 hours at 60~80℃.更多还原
