Different materials use different tensile testing machines
   Tensile testing machine is widely used by customers due to its wide range of applications. However, for different materials and different testing items, the main functions of the required tensile testing machine are naturally different. How to choose one is satisfactory Ruyi, a testing machine that can meet your own requirements, requires a certain amount of energy to consider. Different materials use different tensile testing machines.   1. Thin film materials mainly measure the tensile force and elongation of the material. Since most thin film materials have high elongation, a large-stroke testing machine is required. For example, a tensile testing machine with a stroke of 1 meter;    2. Rubber materials, which mainly detect the tensile strength and elongation of the material. The material has a higher elongation, sometimes reaching more than 1000%, and a large-stroke tensile testing machine must be used , Usually the test space will not be less than 900mm or even larger. This material has high requirements for elongation detection, and displacement instead of deformation can no longer meet the test requirements. Therefore, a large deformation measurement system is indispensable. 4. Waterproof coiled material. The material usually uses a tensile testing machine of 1000-5000N to test the maximum test force and elongation of the material. Due to the addition of many additives to the new material, it has a higher requirement for the fixture of the testing machine. High, otherwise, the test data is not accurate;   5. The maximum test force of the packaging belt and protective net is mainly tested. The test space is not high, and the general tensile stroke 100-200mm is enough;   6. Wire and cable, usually test the maximum test The test space is not large, and the requirements for fixtures are also high;    7. Metal wires such as copper wire, aluminum wire, steel wire, etc., mainly detect the tensile strength and elongation of the material, and the elongation of non-ferrous metals is high, and the maximum can reach 50%, the elongation rate of the steel wire is extremely low, so it is difficult to detect the elongation rate of the steel wire, and a more tensile testing machine is needed;    8. Aluminum foil copper foil, mainly to detect tensile strength and elongation, because the material is very thin, It is usually between 0.005 and 0.2mm, which is very important for the vertical stretching of the material. If you are a little careless, the stretching of the material will be torn. The result is very different from the true value. The coaxiality of the upper and lower clamps of the product, Universality and rigidity of the equipment are important to it;   9. The paper mainly detects the maximum test force and tearing force, and the clamping of the clamp becomes the key to the test accuracy;   10. Non-woven geotextile, mainly detects the maximum test The performance of force, tearing, puncture, bursting, etc. requires high neutrality and firmness of the product fixture. The above is the content of using different tensile testing machines for different materials. Do you understand? There are subtle differences in the functional characteristics of different parts of the testing machine. If you want to obtain a machine with good product performance and functions, it is not the machine itself. The function introduction is enough. When buying a machine, the main thing is to see what kind of test you want to perform, what kind of test purpose you want to achieve, and buy a machine that suits your test purpose.
