The Taber abrasion tester is used for testing various textiles, cloth, paper, paint, plywood, leather, floor tiles, glass, natural rubber, plastic film and other materials to evaluate the wear performance of materials. It is our standard group (Hong Kong) Co., Ltd. independently develops and produces experimental equipment with high cost performance and complete after-sales service. Customers in need are welcome to inquire.
Experimental principle:
Apply a specified load and speed to the test sample placed on the test bench. When the test bench rotates, it drives the grinding wheel to wear the sample. weight loss due to abrasion is the test. The weight difference between the front and back samples was used to estimate the abrasion resistance according to standard methods.
Benefits and Features:
1. The company has been in instrument testing for more than ten yearsand has a after-sales service team;
> 2. Can be different
3. Spare parts are available to solve the problem of long delivery time for spare parts ordering;
4. Provide outsourced maintenance services;
5. Long-term supply of various commonly used test instruments;
6. Keep up with industry standard updates and provide timely
Evaluation of experimental results:
For the evaluation of abrasion resistance, the sample and the standard sample with the same properties can be placed in the same For comparison under the experimental conditions, it is suggested that in the following example, observations can be made from different aspects.
1. Appearance Traits:
Changes in Shine: Changes insurface properties (pilling, fuzz)
Changes in color: first time fibers are visible Broken, holes found for the first time.
2. Physical properties:
Changes in thickness
Changes in air permeability
Changes in weight
Changes in force (stretching or crushing).
3. Weight loss method:
The weight loss per unit area is the difference between the original weight of the sample and the weight after wear, and the percentage of the worn surface of the sample, namely:
Weight loss per unit area = W0-W1/S
In the formula:
W0--the original weight of the sample (g);
W1 ---The weight of the sample after wear (g);
S --- The area of the sample worn (cm2) --This instrument is 20cm2;
If the calculated data is too small, it can be converted to g/m2.
4. Loss of strength method:
The strength difference (%) is the difference between the original strength of the sample and the strength after wear, and the effect on the original strengthPercentage, namely:
Strength difference (%) = A0-A/A0;
where: A0 --- sample original strength (N);
A --- the strength of the sample after wear (N).
