某美发店用空调在安装数月后，其内机蒸发器长U形铜管出现穿孔泄漏现象。对泄漏的铜管进行了宏观检验、金相分析、腐蚀产物成分分析以及复现试验等，分析了其腐蚀泄漏原因。结果表明：该美发店使用的发胶、染发剂、焗油膏等产品使用过程中挥发出的物质，在潮湿环境中聚积在铜管表面水解生成甲酸根、乙酸根等易引起铜管发生蚁巢腐蚀的羧酸根离子以及易引起点腐蚀的氯离子，从而导致铜管发生穿孔泄漏失效。据此建议开发对应更耐腐蚀的空调机型。

The perforation leakage happened to the inner evaporator long U-shaped copper tubes of an air-conditioner used in a hair salon after a few months of installation. Macroscopic examination, metallographic analysis, corrosion product composition analysis and reappearance test were conducted on the copper tube to find out the causes of its corrosion leakage. The results show that the substances volatilizing from the hair sprays, hair dyes, baking ointment and other products used in the hair salon gathered on the surface of the copper tube in the wet environment and formed carboxylic acid ions such as formic acid and acetic acid which easily caused nest corrosion and chloride ions which easily caused pitting corrosion, which resulted in the perforation leakage failure of the copper tube. Accordingly, it was recommended to develop corresponding more corrosion-resistant air conditioning models.
