Thermal paper is a special paper widely used in the printing industry, which is characterized by the ability to produce images or text under thermal action. You may be curious about how to make this unique paper. In this paper, we will introduce the basic process of making the heat-sensitive paper.
Making the thermal paper involves the following key steps:
Substrate selection: The substrate of thermal paper usually consists of two main materials: thermal sensitive sensing layer and base paper. The thermosensitive receptor layer contains thermosensitive dyes and development agents, which react with each other to produce images when heated. The base paper provides the structure and support of the paper. Common base paper materials include cellulose paper and polyester thin films.
Coating the thermal sensitive layer: The core step in the manufacturing process of the thermal paper is to coat the thermal sensitive layer on the base paper. The thermosensitive receptor layer consists of thermosensitive dyes, development agents, and other auxiliary materials. These materials are evenly covered on the surface of the base paper through a coating process.
Dry and curing: After coating the heat sensitive layer, the paper needs to be dried and cured to make the heat sensitive layer firmly attached to the base paper. This step is usually performed by delivering paper to a drying oven or drying chamber to remove moisture and solvent, and make the thermosensitive layer dry and cured.
Cutting and processing: After making heat paper, the paper can be cut and processed to meet the needs of different sizes and shapes. Cutting can be performed using a paper cutter or a cutting tool to ensure that the desired paper size is obtained.
Please note the following points:
The production of thermal paper requires professional equipment and process, generally in specialized manufacturing plants.
The manufacturing process of thermal paper requires strict control of parameters such as temperature, humidity and coating amount to ensure the stability of quality and performance.
Since thermal paper involves chemicals and professional equipment, it is not recommended to try making thermal paper in home or non-professional environments. In conclusion, the production of thermal paper is a complex process involving specialized equipment and process control. If you are interested in learning more about the manufacturing process of thermal paper, it is recommended to refer to the information of professional thermal paper manufacturing companies or research institutions. I hope this article will provide you with a basic overview of thermal paper making. Feel f
