Thermal paper is a processed paper, its manufacturing principle is in the quality of the base paper coated with a layer of "thermal coating" (thermal color layer). Although there are dozens of chemicals used in this discoloration layer, there are at least the following compounds: leuco dyes, the variety of which is widely used, the most commonly used fluorescent compounds; chromogenic agents about 20% or less, commonly used in double Phenol, p-hydroxybenzoic acid; sensitizer about 10% or less, which contains benzenesulfonic acid amide compounds; filler about 50% or less, commonly used calcium carbonate (particles); adhesive about 10% Such as polyvinyl acetate; stabilizers such as dibenzoyl phthalate; lubricants and the like.

Thermal Paper Thermal paper: in the fax machine as a text and graphics communication carrier, that is, as a fax paper; in the medical, measurement system as a recording material, such as ECG drawings, thermal instrument recording paper; applied to the Internet terminal printing paper; In terms of business activities, used to make trademarks, signature (POS), etc., of which the amount of fax paper to occupy the largest proportion.
The principle of the production of thermal paper is coated with plain particles on the plain paper, the composition is a leuco dye phenol or other acidic substances, separated by thin film, in the heat conditions, the film melts, the powder mixture from the color reaction. Paper on the color of the handwriting is unstable, easy to fade, resulting in difficult to identify the contents of the file.
Commonly used lottery is used in thermal paper.
Ordinary thermal paper is not suitable for long-term preservation, but good thermal paper can be saved for 30 years or even longer.
Thermal Paper Thermal paper is specially used for thermal printers and thermal fax machine printing paper, its quality directly affects the print quality and save time, and even affect the printer and fax machine life. Currently on the market of thermal paper good and bad, the state has not yet introduced the national standard, many users do not know how to identify the quality of thermal paper, which for many businesses to control the poor quality of thermal paper provides a convenient, The storage time becomes shorter, the writing is blurred, and the damaged printer is heavy. This article tells you how to identify the pros and cons of thermal paper, so as not to be taken again. Thermal printing paper is generally divided into three layers, the bottom of the paper base, the second layer for the thermal coating, the third layer for the protective layer, the main impact of its quality for the thermal coating or protective layer,
