Testing the tensile properties of rubber using an electronic tensile tester
The rubber of the electronic tensile testing machine has been widely used in various aspects of life and production as a material with good elasticity, so the tensile properties of rubber has become an important indicator for examining the quality of rubber. At present, the tensile properties of rubber are tested according to GB/T528-98 "Determination of tensile properties of vulcanized rubber and thermoplastic rubber". The samples are mainly dumbbell-shaped samples. Testing the tensile properties of rubber specimens is the study of the stress-strain curve of the rubber specimen during the stretching process. The rubber tensile testing machine is started at the specified speed during the test, the specimen is stretched and the marking of the test is followed, and the following items are recorded as required. Several or all of:
1. The force value (breaking strength) when the sample is broken;
2. Elongation of the specimen to a given stress (constant elongation);
3. The yield point corresponding to the elongation (yield point elongation);
4. Elongation at break of the sample (break elongation). a. The force value (fixing stress) when the sample is stretched to a given elongation;
5. The force value corresponding to the yield point (the yield point tensile stress);
6. The maximum force value (tensile strength) that occurs when the sample is stretched to the fracture process;
Bulk grain van has van, tank car, and some cars also with such as air suction and other special loading and unloading functions. In general, bulk grain transport vehicles with loading and unloading speed, to prevent sand and snow effect, suitable for large tonnage transport and other characteristics, widely used in grain-producing farms, large grain depots, flour mills, instant noodles factory, Food transport
