2, operation panel 3, prepare the sample:
1) Select specimens from the same batch of samples.
2) Use standard cutters and slicing machine to cut out the standard test strips required by your company.
4, steps:
1) After turning on the power, turn on the power switch and the power indicator light is on;
2) After the power is on for about 30 seconds, the monitor automatically enters the test state, which means 0.00 display, at which time the monitor no longer bounces;
3) Check whether the thimble of the oil cup is locked. If it is not locked, it must be locked. Check if the air source is leaky. If the air leakage is bad, the air source must be properly adjusted to test;
4) Place the prepared sample between the upper and lower platens and prepare to enter the test;
5) Press Clear to make sure that the display shows 0.00, then press the Peak button.
6) After everything is ready, press the motor start button and the cylinder will automatically press down on the test sample. After 5 seconds, the pressure motor will automatically run and pressurize.
7) When the test strip ruptures, the maximum pressure value is displayed on the display. At this time, the cylinder of the instrument will automatically rise, and the pressure motor will quickly retreat. Be careful not to turn off the power switch.
8) When the maximum value is retained, press the function key twice to save the maximum value. Press the following keys to print the test value.
9) Note: If you need to change the unit value of the force value, press the unit conversion key to switch.
10) After the cylinder returns, remove the test piece. This test is completed.
11) Test other groups of samples according to the 4 to 9 items mentioned above, and pre-record to obtain the average value of the same kind of samples. 12) After the test is completed, turn off the power switch and the power indicator is off.
5, rubber membrane elastic strength correction operation method 1) according to the above test operation method 1-4 items to make the machine in a normal state.
2) Take a standard aluminum foil with a smooth surface and no scratches. Place it on the center of the lower platen. Tighten the handwheel until the indicated pressure reaches 7.5kgf/cm2.
3) Test the maximum rupture strength of aluminum foil according to the test method 5~10.
4) The machine differential value (also called the machine correction value) is calculated:
Example <1>: The standard value of the standard aluminum foil is 11.41kgf/cm2 "Standard value of low-value aluminum foil blasting 8.61kgf/cm2", and the test value is 11.26kgf/cm2.
(11.26-11.41)kgf/cm2
Machine differential value (correction value)=-----------------------×100%=-1.3% (low value)
11.41kgf/cm2
If the final result of the instrument test carton maximum rupture is 20kgf/cm2, the correct result is: 20+(20×1.3%)=20.26kgf/cm2
Example <2>: Standard aluminum foil standard value is 11.41kgf/cm2, test value 12.26kgf/cm2
(12.26-11.41)kgf/cm2
Machine differential value (correction value) =----------------------- × 100% = +7% (high value).
11.41kgf/cm2
If the instrument test carton maximum rupture is 20kgf/cm2, the correct result is: 20-(20×7%)=18.6kgf/cm2
6. Precautions 1) Correctly obtain the test value when correcting. After three or more standard aluminum foils are tested, calculate the average value.
2) How to check that the sample has broken:
2.1 When the value of the monitor breaks when the sample breaks, it will pause for a moment;
2.2 When the sample breaks, it will make a sound (but when some of the samples break, no sound is heard).
3) The conditions for renewing the rubber film in principle:
3.1 Rubber damage ring;
3.2 Has been used for a period of time, such as 30 days or 60 days, when there is distrust of test data.
