What data do we need first to test the mechanical properties of rubber
According to the relevant elastic testing standards, elastic testing generally takes the following parameters or seven parameters:
1. The maximum force value (tensile strength) when the specimen is stretched to break
2. The force value when the sample breaks (breaking strength)
3. Force value corresponding to the yield point (tensile stress at the yield point)
4. The force value when the sample is stretched to a specific strain (constant tensile stress)
5. Strain when the specimen is strained to a specific stress rate (constant stress strain)
6. Elongation according to yield point (Yield point elongation )
7. Elongation at break of specimen (Elongation at break)
Second: Check the circuit of the electronic universal testing machine : Turn on the power switch of the host of the electronic universal testing machine, there is a red indicator light, indicating that the machine has been turned on to test Check whether the computer control system is connected to the testing machine, check whether the serial port connected to the tester and the computer is the same.
3. Check the working status of the electronic universal testing machine: Open the electronics. The host computer of the universal testing machine and the control computer control the moving beam to move up and down and the speedthe up and down movement must be within the standard requirements. Check whether the large deformation gauge is normal, and confirm whether the electronic universal testing machine is in good condition.
Fourth, check the test plan and parameter settings: Check whether the test plan selection is pull test mode, check the test plan parameter settings, e.g. B. Sample size, initial gauge length, given stress, given elongation, test end conditions and other parameters.
5. Check the pattern installation: Install the pattern in the holder, move the beam in a suitable position and install the pattern. When gripping the specimen, the longitudinal axis of the specimen should be kept in line with the axis of the testing machine. Large deflection gauges should be clamped in parallel specimen sections.
6. Check the position of the limit switch : The upper and lower limit devices should be installed in a suitable position, and the position of the lower limit should ensure that the devices do not collide; the position of the upper limit should be larger than the strain distance of the rubber sample.
Reminder: After purchasing the Rubber Tensile Testing Machine, normal manufacturers will send special staff to install it Debugging and professional training for testing machine operators. So if youIf you don't understand something about the operation, you can contact the manufacturer and ask for technical support.
The Rubber Tensile Testing Machine manufactured by Wuhan Guoliang Instrument is equipped with special jig and large deformation device for elastic testing, built-in computer interface and printer interface, can output test report by computer and printer. The test accuracy reaches the national standard of 0.5, and the performance is stable and reliable.
