铝电解电容器用电子铝箔的性能分析与比较

The performance analysis and comparison of electronic aluminum foils used for aluminium electrolytic capacitors

摘要: 利用原子吸收光谱仪(AAS)、电子扫描电镜(SEM)、电子背散射技术(EBSD)、电化学工作站等方法对不同厂家生产的铝电解电容器用电子铝箔各方面的性能进行比较和分析。结果表明,国产铝箔在微量元素设计和杂质控制,立方织构控制方面已达到国外同类产品的先进技术水平,但表面加工质量,氧化层均一性和微量元素的分布控制方面与国外存在差距。

Abstract: Using AAS,SEM,EBSD and Electrochemical Working Station to analyse the properties of electronic aluminum foils for electrolytic capacitor produced different factories.The results show that the technology of trace elements designing,impurity controling and cube texture controling about electronic aluminum produced by the domestic factories has reached the foreign advanced level of the same trade,such as SHOWA.But the processing quality of surface,the uniformity of oxidation film and the controling of trace elements distribution are not as well as the abroad foils,these technologies should be improved.
