The Taber wear tester is used to test the wear of various textiles, fabrics, paper, paint, plywood, leather, tiles, glass, natural rubber, plastic sheet and other materials to evaluate the performance of wear of materials. This is our company qisnun precision test equipment independently developed and produced by Electromechanical Technology Co., Ltd. is a cost-effective and comprehensive after-sales service.
Applicable standard:
ISO 5470-1, ASTM D4060, ASTM D3884, DIN53863.2, GB 4085
Test principle:
Apply a specified load and speed to the test sample placed on the test bench. As the test stand rotates, it drives the abrasive wheel to wear down the sample. The weight lost by abrasion is the difference in weight of the sample before and after the test. Wear resistance is estimated using the standard method.
Evaluation of the result:
For the evaluation of wear resistance, the sample and the standard sample with the same properties can be placed in the same For comparison under the test conditions, it is suggested to observe various aspects in the example following.
1. Appearance properties:
Gloss changes: changes in surface properties (pilling, fluff);
Color changes: the first time fibers are seen Fracture, holes were found for the first time.
2. Physical properties:
Thickness changes;
Changes in air permeability;
Weight changes;
Force changes (stretching or squeezing).
3. Weight loss method:
Weight loss per unit area is the difference between the initial sample weight and the weight after wear, and the percentage of the worn surface of the sample, namely:
Weight loss per unisurface tee = W0-W1/S
In the formula:
W0--the initial sample weight (g);
W1 ---The weight of the sample after wear (g);
S --- The area of the worn sample (cm2)--ThThis instrument measures 20 cm;
If the calculated data is too small, it can be converted to g/m2.
4. Strength loss method:
Strength difference (%) is the difference between the original strength of the sample and the strength after wear, and the percentage of the original resistance, i.e.:
Force Difference (%) = A0-A/A0;
where: A0 --- sample original force (N);
A --- wear example Rear force (N).
