Description

Waterproof coiled material tearing detection device Technical Field The invention relates to the technical field of waterproof coiled material detection, in particular to a waterproof coiled material tearing detection device. Background The tearing performance detection of the waterproof coiled material is a core link for evaluating the physical and mechanical properties of the waterproof coiled material, and is directly related to the reliability of the material in the actual construction and use process. The test is intended to determine the ability of a web to resist penetration by sharp objects or to tear by local external forces, and is a key indicator for evaluating its durability under applied, overlapped and long-term service conditions. At present, the detection is strictly carried out according to the national standard GB/T328 series building waterproof coiled material test method. Because the asphalt and macromolecule waterproof coiled materials have obvious differences in material and mechanical behaviors, different sample shapes and test procedures are correspondingly specified in the standard, but the essence of the waterproof coiled materials belongs to the tearing strength experiment carried out by using a tensile machine. Accurate and reliable tearing performance data has important significance for guaranteeing the quality of waterproof engineering, optimizing material formula and standardizing construction process. However, current testing methods generally rely on the manner in which a universal tensile tester is fitted with a special fixture. This method can hold and test only one sample at a time, and each sample can be tested in a sequential and batch manner even when a control or parallel experiment is required. Because of possible fine fluctuation of environmental conditions and equipment states in the experimental process, the asynchronous sequential testing mode can introduce additional system errors and time variables, so that the testing conditions among different samples are difficult to keep completely consistent. Therefore, the comparability and the contrast accuracy of the obtained experimental data are affected to a certain extent, and the actual influence caused by the slight difference of the performance of the material or the process change is difficult to accurately reflect. Therefore, it is needed to develop a tearing detection device capable of realizing synchronous and same-condition testing of multiple samples, so as to improve the detection efficiency and especially ensure the accuracy and reliability of the comparison experiment result.
