Test the tension of paper
Second, the test equipment
1, a paper specimen
2. A pair of jigs
3. A tensile testing machine.
Third, the test steps
1. Adjust the tensioner horizontally to make it in a horizontal state.
2. Confirm whether the power supply meets the specified requirements.
3. Turn on the power switch of the control panel. At this point, all buttons, indicator lights and control devices are turned on.
4, according to the fixture correctly device paper samples.
5. Adjust the up-and-down stroke setting ring to the upper and lower limits of the required range, and select the appropriate test speed.
6. Press the Start-Down or Up button to lower or raise the middle plate.
7. Start the test. At this point, the display starts to show the tensile force value of the paper sample.
9. Keep the load to a minimum until the paper sample is broken or damaged.
10, record the value.
1 1. Remove broken or damaged paper samples.
12. Hold the pattern as described above, and test again after the displayed value returns to zero.
