Test Principle

Under the impeller rotor, a free state textile sample is continuously subjected to a high-speed impact in the annular track of a cylinder and continuously impinges on the friction lining of the inner wall of the cylinder. In the test process, the specimen is subjected to bending, friction, vibration, tensile and other mechanical forces, wear occurs. Then evaluate the wear resistance of the samples by the weight loss or fracture strength loss before and after friction. This test method is mainly used to evaluate the wear resistance of textiles or other flexible materials.

Test Step

Sample preparation: Cut the specimen according to the standard requirements, if test the fracture strength, test the original fracture strength with half the specimen, and test the fracture strength after wear with the other half sample.

Adjust tachometer: select and install the appropriate rotor, adjust the speed dial to calibrate the accurate speed of the tachometer.

Weight Loss Method

Weigh and record the weight of the sample before testing. Then place the specimen in the accelerator.

Close the accelerator door, open the accelerometer and timer, rub the sample fully at a given speed and time. After friction, stop the accelerometer and remove the sample.

Remove the deposits from the sample with a brush, moisturize and weigh the sample. Calculate the weight loss rate of each sample to 0.01.

Strength Loss Method

Humidifying the sample, measure the fracture strength of the specimen without wear and the fracture strength of the specimen after wear, then calculate the strength loss of each specimen.

The test results are affected by duration, rotor size, shape, and speed. During testing, the test should be stopped when the specimen is curled in the test room or can’t move freely for any other reason.
