The main factors that affect the storage time of three heat-sensitive paper are as follows:
1. Ambient temperature
High temperature effect: High temperature will accelerate the reaction of the chemical coating on the thermal paper, causing the handwriting to fade or disappear. Generally speaking, the temperature control below 30℃ is conducive to extending the storage time. If the temperature exceeds 30 ° C, especially in direct sunlight, the writing of the three heat-proof paper may only be stored for about ten days.
Low temperature effect: Although the direct impact of low temperature on thermal paper is small, the extreme low temperature environment may also have a certain impact on the paper material itself, and indirectly affect the storage time.
2. Ambient humidity
The high humidity environment is easy to lead to the moisture absorption of the paper, which affects the stability of the heat-sensitive coating and accelerates the fading of the handwriting. Therefore, maintaining a dry environment is an important factor in extending the storage time of the three heat-resistant paper.
3. Lighting conditions
Light, especially ultraviolet light, can promote chemical reactions in the heat-sensitive coating, causing the writing to fade. Avoid direct sunlight and store in a cool place to significantly extend storage time.
4. Contact substances
Although the three thermal sensitive paper has a certain waterproof and oil-proof performance, long-term contact with solvents or plasticizers such as grease and alcohol may still affect its stability and shorten the storage time.
Avoid rubbing or scraping with sharp objects to reduce the impact of physical damage on storage time.
5. Paper quality
Different brands, different batches of three thermal sensitive paper may have differences in paper quality, including the thickness of the thermal sensitive coating, uniformity, protective layer performance, etc., which will affect the preservation time.
6. Save the environment
The ideal storage environment should be dry, ventilated, and away from direct sunlight. In such an environment, the writing of the three heat-proof paper can be preserved for a long time.
In summary, in order to extend the storage time of the three thermal sensitive paper, attention should be paid to controlling the ambient temperature and humidity, avoiding direct sunlight and contact with harmful substances, and choosing products with reliable quality. Under normal indoor temperature and humidity conditions, the writing time of the three heat-proof paper can reach one year or even several years. But in extreme environments, the preservation time is greatly shortened. Therefore, it is important to choose the right storage conditions according to the specific use scenario and requirements.
