There is no absolute fixed answer to this question, because it depends on a number of factors, including the specific quality of the thermal paper, the production process, soaking conditions (such as water temperature, water quality). However, based on publicly released information and common sense, we can infer the following:
Characteristics of three heat-proof paper
Three heat-proof paper is a special heat-sensitive paper, with waterproof, oil-proof, PVC and other characteristics. These characteristics make the three heat-resistant paper able to maintain clear and stable printing content in wet or oily environments. In particular, its waterproof properties allow the paper to keep the writing intact even when submerged in water.
Inference of soaking time
1.Laboratory data: It is mentioned that the three heat sensitive paper can be stored for up to 20 years under the theoretical data in the laboratory, and the waterproof performance is excellent, and can cope with extreme situations such as soaking water. Although this does not mean that the paper can be submerged indefinitely without being affected, it does show that the three heat sensitive paper has a certain stability under water.
2.Actual tests:Some manufacturers or users show that the three thermal sensitive paper is completely soaked in water for at least one hour, and there is no significant change in the paper and writing after removal. This further proves the durability of the three heat-proof paper under water.
3.Note: It should be noted that although the three thermal sensitive paper has excellent waterproof performance, long-term immersion or extreme soaking conditions (such as high temperature water, strong acid alkali water, etc.) may still have a certain impact on the paper. Therefore, in practical applications, it should be avoided to soak the three heat-resistant paper in water for a long time.
conclusion
In summary, the three thermal sensitive paper can be submerged for a period of time without affecting the printing content, but the specific soaking time depends on the quality of the paper and soaking conditions. Under normal circumstances, the three heat sensitive paper is completely soaked in water for at least one hour, and the paper and writing should not change significantly after removal. However, in order to maintain the best condition and service life of the paper, it is recommended to avoid soaking the three heat-resistant paper in water for a long time.
