Thermal paper is with the popularity of fax machines around the world and the rapid development, but due to the development of electronic communications, thermal paper is not only in the form of fax paper popularized in the individual family, but also in the commercial, supermarkets, banks, hospitals, airports and other areas. Its use is becoming more and more extensive, more and more varieties, suitable for a wider and wider range. At present, the main areas of application are categorized as follows.
(1) fax machine with thermal paper is mainly used for various types of thermal paper fax machine. There are commercial business use, but also for home use. At present, this type of use of thermal paper machine almost accounted for about half of the total output, is the late 1980s to date, the main direction of thermal paper. Its quality goal is to pursue the high speed of fax recording, high density of lines (blackness) and preservation after recording. Such as from the recording speed, has developed from G2 type to G3 and even G4 type, up to about 15S per A4-sized paper high-speed fax.
(2) printing and terminal recording of thermal paper to adapt to the needs of a variety of new terminal recording equipment, the development of different varieties, can be widely used in word processors, medical testing and industrial testing of the print record, electronic computer-aided design and production (can be referred to as CAD / CMA), counters, cash automatic payment machines (ATM / CD) and portable terminal printers, such as printing, highways, taxis and other receipts.
(3) labels and tickets with thermal paper thermal paper in recent years, the new products lead to the field of labeling, and the development of rapid. It is a combination of thermal paper and self-adhesive labels. In the back of the thermal core paper coated with self-adhesive and laminated to the anti-adhesive paper, for the need to print the label.
Question 2: Who knows what is called thermal paper ah? Heat-sensitive paper thermal paper is coated with a layer of special coating on the thermal raw paper and paper products, used to record text, images. Thermal paper is generally in the raw paper 45 grams / square meter or so, the coating by the various colors of dyes, coloring agents to join other auxiliary chemicals, the characteristics of this coating is heat will melt and color, thermal paper can only be used for heat recording head of the special instrument, when the message is accepted, the thermal recording head that will produce heat, thermal recording head and the thermal paper contact part of the coating will melt and the formation of text and images. Common uses of thermal paper are: fax machines, medical records, airport boarding cards, baggage fees, supermarket cash registers, barcodes, and so on.
Question 3: What kind of paper is thermal paper? Thermal paper is a kind of processed paper, the principle of its manufacture is in the high-quality raw paper coated with a layer of "thermal coating"
In the heat conditions, the sea film melting, powder mixing color reaction. Thermal paper on the color of the handwriting is unstable, easy to fade, resulting in the content of the document is difficult to recognize.
Question 4: What is the role of thermal paper, why use thermal paper thermal paper: in the fax machine as a text and graphics communication carrier, that is, as fax paper; in the medical, measurement system as a recording material, such as electrocardiogram paper, thermal instrumentation recording paper, etc.; applied to the Internet terminal printing paper; in terms of commercial activities, used to produce trademarks, sign code (POS), and so on, which to The use of fax paper occupies the largest proportion.
Thermal paper production principle is in the ordinary paper base coated with particulate powder, the composition of colorless dyes phenol or other acidic substances, separated by a film, in the heat conditions, the film melted, the powder mixed with the color reaction. The color on the thermal paper is unstable, easy to fade, resulting in the content of the document is difficult to recognize.
Commonly used lottery tickets are thermal paper.
Ordinary thermal paper is not suitable for long-term preservation, but good thermal paper has been able to save 30 years or even longer.
Question 5: What is the meaning of thermal paper paper by heating to write the content of the paper
Question 6: What is the principle of thermal paper thermal paper is a special coated processed paper, its appearance is similar to ordinary white paper. Thermal paper surface smooth, is made of ordinary paper as a paper base, coated with a layer of thermal color layer, are coated on the surface of ordinary paper on one side, the color layer is made of adhesive, color rendering agent, colorless dyes (or cryptochrome dyes) composed of microcapsules to be separated, the chemical reaction is in a "latent" state. When the thermal paper meets the heat of the print head, the print head where the color rendering agent and the colorless dyes that are printed on the chemical reaction and discoloration, the formation of graphics.
Thermal paper is placed in the environment above 70 ℃, the thermal coating began to change color. The reason for the discoloration starts with its composition.
Thermal paper coating in the thermal components are mainly two: one is a colorless dye, or hidden color dyes; the other is a color rendering agent. This type of thermal paper is also known as two-component chemical-based thermal recording paper.
Commonly used as colorless dyes are: crystalline violet lactone (CVL), fluorescent alkane system, colorless benzoylmethylene blue (BLMB) or spiropyran system and other substances. Commonly used as a color developer are: parahydroxybenzoic acid and its esters (PHBB, PHB), salicylic acid, 2,4-dihydroxybenzoic acid or aromatic sulfone and other substances.
Thermal paper heat colorless dyes and color rendering agent after a chemical reaction to produce color, so the use of thermal paper in the fax machine to receive signals to print or print directly with a thermal printer, the graphic is displayed. As used as colorless dyes have many varieties, so the color of the handwriting is different, there are blue, fuchsia, black, etc..
Question 7: the difference between a defense thermal and three defense thermal paper thermal paper is waterproof, belonging to the general material thermal labeling paper, thermal paper three defense is: waterproof, oil-proof, anti-wear. Better quality, hope to adopt, thank you
Question 8: What is thermal paper? The so-called thermal paper is coated with a color-forming material containing the thermal signal excitation and its own color information recording paper. That is to say, thermal paper is given on the surface of the paper energy (heat), so that the material (color developer) physical or chemical properties change and get an image of a special coated paper.
Thermal paper is with the popularity of fax machines around the world and the rapid development, but due to the development of electronic communications, thermal paper is not only in the form of fax paper popularized in the individual family, but also in the commercial, supermarkets, banks, hospitals, airports and other areas.
