Abstract

The invention discloses an adhesion inspection device and method for the coating layer of electroplated tin thin steel plate. By adding harsh baking conditions, the sample is first baked at 215°C for 24 minutes, and then the sample is baked with a hundred grid knife. After the sample is baked under this baking condition, it can accurately distinguish the nuances of the coating adhesion of different samples, and the test result is more accurate, which can guide the optimization of the production process and the development of new products. Bring economic benefits and social benefits to enterprises and society, and improve the market competitive advantage of products; secondly, the oven equipment adopted in the present invention can make the storage tray rotate inside the oven by setting a fixing device and a rotating device, so that the oven is baked The baked samples are evenly heated to ensure the consistency of the sample testing conditions and the accuracy of the test results; secondly, the storage tray can be easily taken out and put in from the inside of the oven, and divided into multiple storage areas, which can facilitate the classification and placement of samples.

Description

technical field [0001] The invention relates to the technical field of adhesion inspection of the coating layer of electroplated tin steel sheet, in particular to an adhesion inspection device and method for the coating layer of electroplated tin steel sheet. Background technique [0002] In the prior art, the detection of the adhesion of the coating layer printed on the electroplated tin steel plate usually adopts the ordinary scraping experiment, that is, the tool is used to directly draw a grid on the surface of the sample coating, and then the adhesive tape is pasted, and the adhesion of the tape is observed to judge the adhesion. The sensitivity of this kind of scraping coating experiment is insufficient, and it is impossible to distinguish the subtle differences in coating performance. Although the coating is sometimes pulled off in a large area during the test, there is no peeling, anti-sticking, anti-sticking, etc. in the subsequent process. Grinding and other phenom...
