Rally machine is easy to make rubber rubber wire test problems

Rubber rubber wire has the characteristics of smooth surface,uniform thickness,good elasticity,high strength,high tensile strength and elongation,good light resistance,washing resistance,chemical resistance,etc.,as a textile,clothing and sports culture.Widely used in the business of elastic materials.The tensile strength and elongation of rubber rubber are one of the main performance indicators of its quality.In order to test and verify the performance of the rubber adhesive in actual use,it is necessary to test the tensile strength and elongation of the rubber adhesive before it is put into production.A common test method is to clamp the ends of the rubber filaments respectively into the fixture of the tensile machine,and then perform the tensile test.
Because the rubber rubber wire is fixed by clamping the two ends of the rubber tension tester,the rubber rubber wire is also a round cross-section linear elastic material,which has flexibility,and both ends of the rubber rubber wire are clamped by clamps.The pressure will be flat.During the test,when the rubber filaments are stretched to a certain extent,the rubber filaments will first be broken or detached from the ends of the clamps.The clamping force of the upper fixture,during the rubber rubber testing process,is more likely to produce fractures from both ends,resulting in inaccurate tensile strength and elongation of the test and failure to test the true properties of the rubber adhesive filament.
