摘　　要：电镀锡钢板内涂层剥离缺陷是在化工罐、食品罐、饮料罐等金属包装容器加工成型过程中时常会出现的一种表面缺陷,该缺陷会导致内容物与金属包装容器发生反应,造成腐蚀、变质、泄漏等质量问题,严重影响到产品质量,对于罐装食品的金属包装容器严重影响到广大消费者的食品安全。通过使用金相显微镜、辉光分析、激光共聚焦分析、能谱分析,对电镀锡钢板内涂层剥离缺陷进行系统研究。结果表明:热卷钢卷表面存在重皮缺陷,在冷轧、镀锡生产加工过程中导致了电镀锡钢板表面产生重皮分层缺陷,部分重皮未漏光,针孔检测仪无法检测到,导致存在重皮分层缺陷的镀锡板流入印刷、制罐环节,内涂加工完成后在金属容器加工过程中在外力作用下,重皮分层缺陷处出现与金属包装容器材料剥离缺陷。通过优化热轧钢卷材质纯净度、增加检验频次,此类缺陷有了明显改善。The peeling defect of inner coating of electroplating tin steel plate is a surface defect that often occurs in the processing process of chemical cans,food cans,beverage cans,etc.The defect will cause the reaction of contents with metal packaging container,corrosion,deterioration,leakage and seriously affect product quality.For the metal packaging container of canned food,seriously affect the food safety of consumers.Through the use of gold microscope,glow analysis,laser confocal analysis,the peeling defect of electroplating tin steel plate is systematically studied.The results show that there is heavy defects on the surface of the hot coil,in the process of cold rolling and tin plating production led to the defects of plating tin plate layered surface,part of the heavy skin without light leakage,pinhole detector could not detect,lead to double layered tin plate into printing,canning link,after the processing in the metal container processing under the external force,double layer defects and metal packaging container material stripping defects.By optimizing the hot rolling steel coil material purity,increase the inspection frequency,such defects have significantly improved.
