How is the wear resistance of the enhanced hybrid carbon ribbon tested?

The wear resistance of enhanced hybrid carbon ribbons is usually evaluated through a series of standardized tests. These tests aim to simulate the wear that carbon ribbons may experience in actual usage environments and quantify their wear resistance. Here are some common wear resistance testing methods:

1. Friction test:

Testing instrument: Use a friction meter that can apply constant pressure and move the friction head at a fixed speed.

Testing method: Fix the sample with reinforced mixed carbon ribbon on the testing platform, and then set the parameters of the friction meter (such as pressure, speed, friction frequency, etc.). After starting the friction tester, the friction head will perform reciprocating or unidirectional friction on the carbon ribbon.

Evaluation criteria: Observe and record the surface condition of the carbon ribbon after friction, such as whether there is wear, detachment, or discoloration. Usually, the wear resistance of carbon ribbons is evaluated by comparing the changes before and after friction.

2. Scratch test:

Testing instrument: Scraper, which can simulate the scraping effect of sharp objects on carbon ribbon.

Testing method: Fix the carbon ribbon sample on the testing platform, and then use the blade of the scraper to scrape the carbon ribbon at a certain angle and pressure.

Evaluation criteria: Observe and record whether there are scratches, damages, or ink peeling on the surface of the carbon ribbon after scratching. Evaluate the wear resistance of carbon ribbons by comparing their changes under different scratching conditions.

3. Alcohol wipe test:

Test method: Wet a cotton swab or wiping cloth with a specified concentration of alcohol solution, and then wipe the surface of the carbon ribbon. The frequency and intensity of wiping can be set according to the testing requirements.

Evaluation criteria: Observe and record whether there is ink peeling, discoloration, or blurring on the surface of the carbon ribbon after wiping. This testing method helps evaluate the wear resistance of carbon ribbons when in contact with chemical solvents.

4. Wear resistance cyclic test:

Testing method: Place the carbon ribbon sample in a wear resistance cycling testing machine, which can simulate continuous wear in actual use. By setting a certain number of cycles and wear conditions, continuous wear tests are conducted on the carbon ribbon.

Evaluation criteria: After the test is completed, check the degree of wear of the carbon ribbon, such as wear area, wear depth, etc. Evaluate the wear resistance of different carbon ribbons by comparing their wear under the same testing conditions.

When conducting wear resistance testing, the following points should be noted:

Ensure consistency of testing conditions, including temperature, humidity, testing speed, etc., to ensure accuracy and comparability of test results.

Select appropriate testing methods and parameters to simulate wear conditions in actual usage environments.

Objectively and accurately record and evaluate the test results in order to scientifically quantify the wear resistance of carbon ribbons.

In summary, the wear resistance testing of enhanced hybrid carbon ribbons usually includes methods such as friction testing, scratch testing, alcohol wiping testing, and wear resistance cycling testing. These testing methods can simulate the wear situation in actual usage environments and quantitatively evaluate the wear resistance of carbon ribbons.
