What is the thermal sensitivity of the three proof thermal paper?

The thermal sensitivity of three proof thermal paper is an important performance indicator, which determines the response speed and clarity of thermal paper to temperature changes when heated. The thermal sensitivity of the three proof thermal paper can be explained from the following aspects:

1、 Definition and importance

Thermal sensitivity refers to the speed and degree at which chemical substances in the surface coating of thermal paper react and develop color when heated. This performance indicator is crucial for the application of thermal paper in printing, recording, labeling, and other fields, as it directly affects the clarity, speed, and stability of printing.

2、 Influencing factors

The thermal sensitivity of three proof thermal paper is affected by various factors, mainly including:

Coating formula: The coating of thermal paper contains chemical substances such as colorants and color developers, and the types and ratios of these substances directly affect thermal sensitivity.

Paper quality: The substrate, thickness, and tightness of paper can also affect thermal sensitivity. For example, thicker paper may require higher temperatures to trigger color reactions.

Printing conditions: Temperature, pressure, speed, and other conditions during printing can also affect thermal sensitivity. Generally speaking, higher temperatures and appropriate pressures help improve thermal sensitivity.

3、 Testing methods

To test the thermal sensitivity of the three proof thermal paper, the following methods can be used:

Static color performance test: By controlling certain temperature and time conditions, observe the color development of thermal paper to evaluate its thermal sensitivity.

Dynamic Color Performance Test: Observe the color development speed and stability of thermal paper under continuously changing temperature conditions to evaluate its dynamic performance in terms of thermal sensitivity.

4、 Performance performance

Three proof thermal paper usually has high thermal sensitivity due to its special coating formula and paper quality. This enables it to quickly and clearly color when heated, meeting the needs of various application scenarios. At the same time, the three proof thermal paper also has waterproof, oil proof, alcohol proof and other characteristics, further enhancing its stability and durability in harsh environments.

5、 Application scope

Due to its high thermal sensitivity and excellent three proof performance, three proof thermal paper is widely used in various fields such as retail, logistics, medical, catering, etc. In these fields, three proof thermal paper is used as labels, receipts, bills, etc. to meet various printing and recording needs.

In summary, the three proof thermal paper has high thermal sensitivity, which makes it perform well in various application scenarios. However, the specific thermal sensitivity values may vary depending on different product formulations and testing conditions. Therefore, when selecting and using three proof thermal paper, it is recommended to evaluate and choose based on specific application requirements and testing conditions.
