碱性锌锰电池的密封失效与检测

Seal failure and its detection of alkaline Zn/MnO_2 battery

将酸碱指示剂甲酚红喷施在受碱液污染的电池或零配件表面,用肉眼或显微镜即可观察到微量碱痕迹的变色现象。变色的形态可帮助确定钢壳封口内表面存在的微细漏液通道,以及密封圈存在的漏液缺陷。

By spraying acid-base indicator cresol red onto the surface of battery or parts, the discoloration of trace base mark could be observed by naked eye or microscope. The shape of discoloration could help to detect micro leakage channel existed on the inner surface of steel can sealing,leakage defects existed on sealing ring.
