摘要

在一个有八年历史的公寓楼的829户家庭中,通过用苯并三唑水溶液填充喷淋铜管,研究了使用苯并三氮唑(BTAH)抑制喷淋铜管点蚀的可行性。BTAH处理161天后,漏水率比前一年减少了约90%。通过光学显微镜、扫描电子显微镜、能量色散光谱、X射线光电子能谱和X射线衍射分析研究了两个喷淋铜管中的一个的泄漏,以确定腐蚀坑内Cu-BTA膜的形成。腐蚀坑的所有内部部件都涂有Cu-BTA膜,这表明BTAH分子穿透了腐蚀产物。在腐蚀坑的底部,Cu-BTA膜的厚度约为2nm。一层CuCl和Cu2O相位于Cu-BTA膜下。这种复杂的结构有效地防止了腐蚀坑在洒水喷头铜管中的传播,并减少了漏水。

Pitting Corrosion Inhibition of Sprinkler Copper Tubes via Forming of Cu-BTA Film on the Inner Surface of Corrosion pits
The feasibility of using benzotriazole (BTAH) to inhibit pitting corrosion in the sprinkler copper tubes was investigated by filling the tubes with BTAH-water solution in 829 households at an eight-year-old apartment complex. The water leakage rate was reduced by approximately 90% following BTAH treatment during 161 days from the previous year. The leakage of one of the two sprinkler copper tubes was investigated with optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction analysis to determine the formation of Cu-BTA film inside the corrosion pits. All the inner components of the corrosion pits were coated with Cu-BTA films suggesting that BTAH molecules penetrated the corrosion products. The Cu-BTA film was about 2 nm in thickness at the bottom of a corrosion pit. A layer of CuCl and Cu 2 O phases lies under the Cu-BTA film. This complex structure effectively prevented the propagation of corrosion pits in the sprinkler copper tubes and reduced the water leakage.
