空调器铜管“蚁巢腐蚀”泄漏失效分析

Failure Analysis of "Nest Corrosion” Leakage of Air Conditioner's Copper Tube

对ACR(空调制冷)铜管"蚁巢腐蚀"泄漏失效实例进行了宏、微观泄漏特征分析确认。通过红外光谱法对腐蚀表面物质进行定量测量,及对加工工艺、用户环境腐蚀倾向物质进行定性定量测试,方法准确可行。确定了本次"蚁巢腐蚀"物质集中波数段及物质,也提供了可靠的高耐腐空调器防护措施。

This paper analyzed the ＂nest corrosion＂ leakage of air conditioner＂ s copper tube in details. It adopted the quantitative measurement for corrosion surface material through infrared spectrum, and the qualitative and quantitative testing for process and user＇ s envi ronment corrosion materials. The method is accurate and feasible. The ＂nest corrosion＂ sub- stance concentration wave number and material was determined. Moreover, this paper also ful- filled the defend precautions for air conditioner.
