To test the scratch resistance of all resin carbon ribbon, the following methods can be used:

1、 Common testing methods

Scratch test with sharp or hard objects:

Use ordinary sharp tools or hard objects (such as nails) to gradually increase the friction force on the surface of the printed label.

Observe the difficulty of scratching off the label handwriting to determine the scratch resistance of the carbon ribbon.

2、 Professional testing methods

Pencil hardness test:

This method is suitable for measuring the scratch resistance of hard surface materials.

Scratch the surface of the printed label using pencils of different hardness (such as 6B, 4B, 2B, HB, etc.).

Observe the situation where the label handwriting is scraped off, and select the hardness of the hardest pencil that can scrape off the handwriting to evaluate the scratch resistance of the carbon ribbon.

Eraser wiping test:

Use different types of erasers (such as 2B, 4B, 6B, etc.) to wipe the surface of the printed label.

Record the number or duration of erasers until the label begins to blur or completely disappear.

Evaluate the scratch resistance of different carbon ribbons by comparing their rubber eraser resistance times or times under the same conditions.

Taber abrasion test:

This is a widely used testing method for materials such as surface coatings and printed materials.

Test the sample using a rotating scraping head to simulate the wear situation during actual use.

Evaluate the scratch resistance of carbon ribbon based on the degree of wear and clarity of handwriting after testing.

3、 Practical application testing

Environmental simulation testing:

Place the printed label under different environmental conditions (such as high temperature, high humidity, low temperature, etc.) and observe the changes in the label handwriting.

Especially in environments that may be subject to scratches (such as clothing friction, rubbing during washing, etc.), evaluate the scratch resistance of carbon ribbons.

Long term storage testing:

Keep the printed labels for a long time and regularly check the clarity and completeness of the label handwriting.

Evaluate the scratch resistance and long-term storage performance of carbon ribbon by comparing the changes in label handwriting at different time points.

4、 Precautions

Test conditions:

During testing, the consistency of testing conditions should be ensured, such as scraping force, speed, angle, etc.

For professional testing methods, relevant standards and specifications should be followed for operation.

Sample selection:

Representative samples should be selected for testing to ensure the accuracy and reliability of the test results.

Result evaluation:

Based on the test results and practical application requirements, evaluate whether the scratch resistance of the carbon ribbon meets the requirements.

Through the above methods, the scratch resistance of all resin carbon strips can be comprehensively and objectively tested, providing strong support for practical applications.
