DEVICE FOR TESTING PEEL STRENGTH OF FLEXIBLE MATERIALS FROM SUBSTRATE

摘要

FIELD: testing equipment.;SUBSTANCE: test fixture for testing the peel strength of flexible materials, for example foil, paper, polyvinyl chloride, polyethylene, fluoroplastic, from the substrate. Invention relates to a testing technique, intended to determine the strength when flaking flexible foil materials from a substrate. Test fixture for testing the peel strength of flexible foil materials from a substrate, including a press and guide series of rollers, between which is placed a sample adhered to a rigid substrate, ensuring peeling of the flexible material from the surface of the base of the sample at the required angle, by fixing them with a series of holes made at a predetermined angle in two side plates arranged vertically and connected to a mounting base, and the sample is freely movable between the rows of rollers, the fastening base moves relative to the axis of application of the tensile load directed along the strip of flexible material, in the interval fixed by two limiters located on the transition, fixed on a stationary grip of the testing machine.;EFFECT: improved accuracy of test results and simplified measurement.;1 cl, 2 dwg
