How to evaluate the solvent resistance of color mixed carbon ribbon?

Evaluating the solvent resistance of color blended carbon ribbons is an important step that determines their stability and durability in specific chemical environments. The following is a systematic evaluation method:

1、 Determine evaluation objectives

The purpose of the evaluation is to understand the performance of colored mixed carbon ribbon in specific solvents, such as whether it will fade, dissolve, or deform.

2、 Select test solvent

Select representative solvents for testing based on actual application scenarios. Common solvents include water, alcohol, gasoline, xylene, etc. It should be ensured that the selected solvent fully reflects the solvent resistance of carbon ribbon in practical applications.

3、 Prepare test samples

Print test patterns on specialized test media using colored mixed carbon ribbon, which should include text, numbers, symbols, and graphics to ensure a comprehensive evaluation of the carbon ribbon's solvent resistance.

Ensure that the test samples are completely dry to avoid the influence of moisture or other factors on the test results.

4、 Conduct solvent resistance testing

Immersion test:

Soak the test sample completely in the selected solvent, and determine the soaking time and temperature based on the actual application scenario of the carbon ribbon.

After soaking, take out the test sample and gently wipe the surface solvent with a clean cloth or tissue, then observe the color change, dissolution or deformation of the sample.

Wipe test:

Use a cloth or tissue soaked in solvent to wipe the test sample back and forth several times, simulating the solvent wiping situation that carbon ribbon may encounter in practical applications.

Observe the wiped sample and evaluate its color change, dissolution, or scratch marks.

5、 Observation and evaluation

Color change: Evaluate whether the color of the test sample changes after soaking or wiping, such as fading or discoloration.

Dissolution situation: Observe whether the test sample has dissolved or residual after dissolution.

Deformation situation: Evaluate whether the test sample undergoes deformation or dimensional changes after soaking or wiping.

6、 Record and analyze

Detailed records of all parameters and results during the testing process, including solvent type, soaking time, temperature, wiping frequency, etc. Perform data analysis on the test results to determine whether the solvent resistance of the colored mixed carbon ribbon meets actual requirements.

7、 Reference standards and specifications

When conducting solvent resistance testing, relevant national or industry standards such as GB/T 40724-2021 can be referred to to ensure the scientific and authoritative nature of the testing methods and evaluation standards.

Through the above steps, the solvent resistance of color mixed carbon ribbon can be comprehensively evaluated, providing reference for its selection in practical applications. Meanwhile, good testing methods and strict evaluation criteria are also key factors in ensuring the accuracy of evaluation results.
