Matters to be considered in Rubber Tensile Testing Machine

Precautions for the rubber tensile testing machine to carry out rubber tensile strength It has good elasticity and plasticity, and is widely used in various industries. Because each industry has different requirements for rubber materials, a detailed study of the mechanical properties of rubber materials is necessary to determine whether it meets the relevant product requirements. When you use the Rubber Tensile Testing Machine to do the rubber tensile test, you need to pay attention to the following things

What data do we need first to test the mechanical properties of rubberEPPTextile Testing Instruments, Testing Equipment Manufacturer

According to the relevant elastic testing standards, elastic testing generally takes the following parameters or seven parameters:EPPTextile Testing Instruments, Testing Equipment Manufacturer

1. The maximum force value (tensile strength) when the specimen is stretched to breakEPPTextile Testing Instruments, Testing Equipment Manufacturer

2. The force value when the sample breaks (breaking strength)EPPTextile Testing Instruments, Testing Equipment Manufacturer

3. Force value corresponding to the yield point (tensile stress at the yield point)EPPTextile Testing Instruments, Testing Equipment Manufacturer

4. The force value when the sample is stretched to a specific strain (constant tensile stress)EPPTextile Testing Instruments, Testing Equipment Manufacturer

5. Strain when the specimen is strained to a specific stress rate (constant stress strain)EPPTextile Testing Instruments, Testing Equipment Manufacturer

6. Elongation according to yield point (Yield point elongation )

7. Elongation at break of specimen (Elongation at break)EPPTextile Testing Instruments, Testing Equipment Manufacturer

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. EPPTextile Testing Instruments, Testing Equipment Manufacturer

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. EPPTextile Testing Instruments, Testing Equipment Manufacturer

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. EPPTextile Testing Instruments, Testing Equipment Manufacturer
