Use of Geotextile Wear Tester:

★ Test the tested samples in the standard atmosphere specified in GB6529.

★ Place the tested sample on the stationary upper plate, and clamp the sample with clamps at both ends of the plate. Place the abrasive on the reciprocating lower plate, and clamp the two 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 load of (6 ± 0.01) ㎏ including 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 and grinds for 750 cycles at a prescribed frequency or until the sample wears through. If the sample is worn through before the specified period, the number of cycles during which the sample is worn through and the sample is worn should be reported. If there is an abnormal situation in the middle, you can press the stop button to stop, and press the counter to clear it next time key.

★ If the sample or abrasive material slips in the clamp, discard the sample, wake up and test another sample, adjust the abrasive material after each test, and pull the reference sample and the abrasion sample according to the provisions of CB / T3923.1. Extension test.

★ Calculation and expression of the results of the geotextile abrasion tester: Calculate the percentage of strength loss for each group of tests, ** to 1%: Strength loss rate (%) = [(FA-FB) ÷ FA] × 100 Reference specimen fracture strength, N; FB—Abrasion specimen fracture strength, N.
