The problem that the tension machine is easy to produce when testing the rubber rubber wire:
Rubber rubber yarn has the characteristics of smooth surface, uniform thickness, good elasticity and high strength. It also has high tensile strength and elongation, good light fastness, washing resistance and chemical resistance. It is used as textile, clothing and sports culture. Elastic materials widely used in business. The tensile strength and elongation of rubber filaments are one of the main performance indicators of their quality. In order to test and verify the performance of rubber rubber filaments in actual use, it is necessary to test the tensile strength and elongation of rubber rubber filaments before putting them into production. A common test method is to clamp the ends of the rubber rubber into the clamp of the tensile machine and then perform the tensile test.
Since the rubber rubber wire is fixed by clamping the two ends of the tensile testing machine fixture, the rubber rubber wire is a circular cross-section linear elastic material, and has softness, and both ends of the rubber rubber wire are clamped by the clamp. The pressure will be flat. During the test, when the rubber rubber wire is stretched to a certain extent, the rubber rubber wire will first break or fall off from the ends of the clamped ends of the clamp. The clamping force of the upper clamp and the rubber rubber wire test process are more likely to cause breakage from the ends of the two ends, resulting in inaccurate tensile strength and elongation of the test, and the true performance of the rubber rubber filament cannot be tested.
