本发明提供了一种覆膜铁表面膜层结合力的评价方法。环氧树脂与PET膜在结构上具有相似性，故本发明通过在镀铬板表面涂覆环氧树脂，模拟PET膜与镀铬板的结合，采用热振实验来衡量镀铬板表面与有机膜的结合能力，从而对膜层结合力的差异进行检测对比。本发明评价方法操作简单，可以根据实验结果直观看出不同镀液体系、不同结构的镀铬板表面与薄膜之间的结合力差异性，具有快速、有效、准确且绿色环保的优点。

The invention provides a method for evaluating the adhesion of a film coated iron surface facial mask layer. The structure of epoxy resin and PET film is similar, so the present invention simulates the bonding between PET film and chrome plate by coating epoxy resin on the surface of the chrome plate, and uses thermal vibration experiments to measure the bonding ability between the chrome plate surface and the organic film, thereby detecting and comparing the differences in the bonding strength of the film layers. The evaluation method of the present invention is easy to operate, and the difference in adhesion between the surface and thin film of chromium plated plates with different plating solution systems and structures can be visually observed based on experimental results. It has the advantages of fast, effective, accurate, and environmentally friendly.
