土工合成材料磨损试验仪使用方法

★在GB6529规定的标准大气中试验已调试过的试样。

★将已调试过的试样放在静止的上平板上,在平板的两端用夹具将试样夹紧。将磨料放在可往复运动的下平板上,用夹具在平板的两端夹紧。

★将上平板放在下平板之上,使试样和磨料对齐。

★将上平板施加包括上平板重量在内共(6±0.01)㎏的荷量。

★打开电源开关,设定好所需磨损周期,本试验仪开启磨损试验,本机每分钟90周期的频率进行工作,以规定的频率磨750周期,或者直到试样磨穿。如果试样在规定的周期之前磨穿,需报告试样磨穿和试样磨穿时的周期数,如中途有异常情况,可按下停止键停车,下次试验时需按下计数器清零键。

★如果试样或磨料在夹子内产生滑移,舍弃试样,惊醒调整后试验另一块试样,每次试验后更换磨料,按CB/T3923.1的规定分别对参照样和磨损样进行拉伸试验。

★土工布磨损试验仪结果的计算和表示: 计算每组试验的强力损失百分率,精确到1%: 强力损失率(%)=[ (FA-FB) ÷FA] ×100 式中:FA—参照样断裂强力,N; FB—磨损样的断裂强力,N.

Geotextile wear tester
★ Test the tested specimens in the standard atmosphere specified in GB6529.
★ Place the calibrated sample on the stationary upper plate and clamp the sample with the clamp at both ends of the plate. The abrasive is placed on a reciprocable lower plate and clamped at both ends of the plate with a clamp.
★ Place the upper plate on the lower plate to align the sample with the abrasive.
★ Apply a total of (6 ± 0.01) kg of the upper plate to the weight of the upper plate.
★ Turn on the power switch and set the required wear cycle. The tester starts the wear test. The machine works at a frequency of 90 cycles per minute, grinding 750 cycles at the specified frequency, or until the sample wears through. If the sample is worn through before the specified period, the number of cycles during the wear of the sample and the wear of the sample shall be reported. If there is an abnormal situation in the middle, press the stop button to stop, and press the counter to clear the next test. key.
★If the sample or abrasive slips in the clip, discard the sample, and test another piece after the wake-up adjustment. Replace the abrasive after each test and pull the reference and wear samples according to CB/T3923.1. Stretch test.
★ Calculation and representation of geogrid abrasion tester results: Calculate the percentage of strong loss in each group of tests, accurate to 1%: Strength loss rate (%) = [(FA-FB) ÷FA] × 100 where: FA - reference Breaking strength, N; FB—wearing fracture strength, N.
