How to measure and evaluate the adhesion of enhanced hybrid carbon ribbon?

The enhanced adhesion of mixed carbon ribbon can be measured through a series of standardized testing methods and evaluation criteria. The following are the detailed steps and considerations for measuring and evaluating its adhesion force:

Measuring methods

1. Standard wiping test:

Prepare a certain length of reinforced mixed carbon ribbon, unfold it and fix it on a horizontal surface.

Use white non-woven fabric that meets the standard and fold it into four layers to place under the fixed carbon tape.

Apply appropriate pressure on the carbon ribbon using a pen of uniform quality, and push the pen tip in a fixed direction.

Then gently wipe the carbon tape along the direction of the pen tip with non-woven fabric until there are no more visible carbon tape residues on the non-woven fabric.

Repeat the above steps several times (usually three times), and evaluate the adhesion of the carbon tape by the color and quantity of the residue on the non-woven fabric after wiping.

2. Adhesion tester test:

Hang the sample with reinforced mixed carbon ribbon vertically on the test stand.

Hang a weight of the specified weight at the lower end of the sample and measure the displacement or time required for the sample to detach.

This method can quantitatively evaluate the adhesion of carbon ribbon and provide more accurate measurement data.

Evaluation criteria

1. Industrial standards:

According to different industries and application scenarios, there will be corresponding adhesion testing standards and requirements. For example, some industries may require carbon ribbon to have almost no residue on non-woven fabric after a certain number of wiping cycles.

2. Environmental adaptability:

Consider the impact of factors such as temperature, humidity, and chemical substances that carbon ribbon may encounter in actual usage environments on its adhesion. Ensure that the carbon ribbon maintains sufficient adhesion under these conditions.

3. Compatibility:

Evaluate the adhesion performance of carbon ribbon with different materials such as paper, plastic, metal, etc. Ensure that the carbon ribbon can adhere well to various materials and provide long-lasting printing effects.

4. Durability:

Evaluate the changes in adhesion of carbon ribbon after long-term use through methods such as abrasion resistance testing and weather resistance testing. Ensure that the carbon ribbon maintains stable adhesion performance during long-term use.

Matters needing attention

1. Consistency of testing conditions:

When conducting adhesion testing, it is important to ensure consistency in testing conditions, including temperature, humidity, testing speed, etc., to ensure the accuracy and comparability of the test results.

2. Representative of the sample:

The selected samples should be representative and able to truly reflect the adhesion performance of the carbon ribbon. At the same time, it should be ensured that the number of samples is sufficient to provide reliable statistical data.

3. Applicability of testing methods:

Select appropriate testing methods based on specific testing requirements and conditions. For example, for scenarios that require quantitative evaluation of adhesion, the adhesion tester testing method can be chosen; For scenarios that require evaluating the adhesion performance of carbon ribbons under different conditions, multiple testing methods can be selected for comprehensive evaluation.

In summary, enhancing the adhesion of mixed carbon ribbon can be measured through standard wiping tests and adhesion tester tests, and evaluated based on factors such as industrial standards, environmental adaptability, compatibility, and durability. During the testing process, attention should be paid to maintaining consistency in testing conditions and ensuring the representativeness of the sample and the applicability of the testing method.
