What is the standard for heat resistance testing of all resin carbon ribbon?

The heat resistance testing standards for all resin carbon ribbons usually involve multiple aspects, including testing methods, testing conditions, evaluation criteria, etc. The following is a detailed summary of the heat resistance testing standards for all resin carbon ribbons:

1、 Testing method

High temperature environment placement test:

Attach the printed label to a dedicated trial board and place it in a set high temperature environment.

According to the temperature resistance specifications of the carbon ribbon, for example, if the carbon ribbon claims to withstand a temperature of 150 ° C, it should be placed in an environment at 150 ° C for a period of time (such as 24 hours, 48 hours, etc.).

After the test is completed, check if the printed content of the label is still clear and readable, and if there are any deformations, bubbles, or detachment of the label.

Printing test combined with high temperature environment:

Conduct printing tests in high temperature environments to observe the clarity, contrast, stability, and compatibility of printed images and text with the printing medium.

Standard test files can be used for printing, and then the printing effect can be evaluated.

2、 Test condition

Temperature control:

The testing temperature should be set according to the temperature resistance specifications of the carbon ribbon, and ensure that the temperature of the testing environment is uniform and stable.

Usually, the testing temperature is higher than the normal operating temperature of the carbon ribbon to evaluate its heat resistance under extreme conditions.

Time control:

The testing time should be set according to actual needs to fully evaluate the heat resistance of the carbon ribbon in high temperature environments.

The testing time may vary from a few hours to several days, depending on the testing purpose and the temperature resistance specifications of the carbon ribbon.

Environmental control:

In addition to temperature, factors such as humidity and air pressure in the testing environment should also be controlled to ensure the accuracy of the test results.

3、 Evaluation criteria

Print content clarity:

After the test is completed, check if the printed content of the label is still clear and readable.

If the printed content appears blurry, faded, or other phenomena, it indicates that the heat resistance of the carbon ribbon is poor.

Label integrity:

Observe whether the label is deformed, blistered, or detached.

If the above problems occur with the label, it indicates that the carbon ribbon may not be able to maintain stability in high temperature environments.

Comparative testing:

Different brands or models of all resin carbon ribbons can be tested under the same conditions, and their heat resistance performance can be evaluated by comparing the test results.

4、 Reference standard

Although there is currently no universal standard specifically for heat resistance testing of all resin carbon strips, relevant national standards, industry standards, or enterprise standards can be referenced when conducting testing. For example, standards such as GB/T 40724-2021 may contain content related to the evaluation of carbon ribbon performance, which can serve as a reference for testing.

In summary, the heat resistance testing standards for all resin carbon ribbons involve multiple aspects such as testing methods, testing conditions, and evaluation criteria. When conducting testing, appropriate testing methods and conditions should be selected based on actual needs, and evaluation should be conducted with reference to relevant standards.
