SEM/EDS法和XRF法在电工胶带检验中的应用

目的探索电工胶带带基的元素检验方法。方法利用扫描电镜/能谱法（SEM/EDS）对电工胶带带基中的主体元素进行定量分析,通过SPSS软件对SEM/EDS定量分析法检测出的主体元素（Cl和Ca）相对含量进行统计分析;利用X射线荧光光谱法（XRF）对电工胶带带基中的微量元素进行定性分析。结果34个品牌红色电工胶带组成的561组样品对通过SEM/EDS定量分析法可以区分539组,区分率达到96.1%;根据XRF法定性分析测出的Mg、Al、Si、S、Ti、Sb、Ba、Pb微量元素的不同组合可将34种电工胶带分成11组,两种方法结合可使不同品牌红色电工胶带的区分率达到98.4%。结论SEM/EDS法和XRF法结合可以实现同种颜色、不同品牌电工胶带的高效区分。

The Application of SEM/EDS and XRF Methods in Insulation Tapes Analysis

Objective To study the analytical methods of the elements in the backing of insulation tapes of the same color.Method Scanning electron microscopy/energy dispersive spectroscopy(SEM/EDS) was used for determining the relative amounts of two main elements,Cl and Ca,in the backing,and SPSS software was used for statistical analysis.X-ray fluorescence(XRF) was used for detecting the trace elements.Results Through the SEM/EDS quantitative analysis by comparing the relative amounts of Cl and Ca,539 sample groups could be distinguished from the total 561 groups,and the discrimination rate was 96.1%.Based on the XRF qualitative analysis,34 brands of red insulation tapes were divided into 11 groups according to their different combinations of Mg、Al、Si、S、Ti、Sb、Ba、Pb.The total discrimination rate was 98.4% when combining these two methods.Conclusion SEM/EDS and XRF methods can be used to distinguish different brands of insulation tapes of the same color.
