Method for detecting surface adhesion of cold-rolled electroplated tin steel plate

The invention discloses a method for detecting the surface adhesive force of a cold-rolled electrotinned steel plate, and mainly solves the technical problems that the surface adhesive force of the existing cold-rolled electrotinned steel plate cannot be accurately detected and the detection precision is low. The invention discloses a method for detecting the surface adhesive force of a cold-rolled electroplated tin steel plate. The method comprises the following steps: 1) preparing a sample; 2) carrying out deformation treatment on the sample, and impacting two indentations on the sample by using a cupping tester; 3) cooking the sample subjected to cupping impact in a sterilization pot; 4) carrying out gridding treatment on the sample; and 5) evaluating the adhesive force of the surface of the sample in a manner of pasting and tearing the surface of the sample by using a 3M610 adhesive tape, observing the falling area of the paint film in the scribing area, and grading according to the ratio of the area of t
