Device for determining the force of uneven peeling of the adhesive layer of flexible materials from a rigid plate

One of the most important performance indicators of flexible adhesives is the peeling force from the rigid substrate. The most common method for determining this parameter is the method of uneven peeling of flexible material from a rigid plate at an angle of 90о. Devices used today to determine this parameter do not provide high accuracy of measuring the peeling force due to design features. In this paper, a method for determining the exfoliation force of flexible material from a rigid plate with self - regulating maintenance of the exfoliation angle equal to 90о is theoretically justified and experimentally confirmed. As a result of experimental studies using a medical patch, it was found that the developed device allows clearly recording and measuring with high accuracy the exfoliation force of flexible material from a rigid plate with self - regulating maintenance of the exfoliation angle equal to 90±3о.
