The manufacturing principle of thermal paper:
The manufacturing principle of thermal paper is coating particle powder on general paper, its ingredient is colorless dye phenols or other acidic material, they are separated by thin film. Under heating conditions, thin film melt and mix with powder, then they come into being chromogenic reaction. The writing on thermal paper is not stable and easy to fade away, so files on it is hard to recognize. Thermal coating will change when its temperature is over 70℃。
The ingredient of thermal paper: there are two main thermal elements in thermal paper coating: one is colorless dye or leuco dye, the other is color developing agent. This kind of thermal paper is also called bi-component chemical type thermal paper, colorless dye and color developing agent produce chemical reaction and get color after heating, so the image-text comes into being when using thermal paper receive signal on the fax machine or printing by printer directly.
