A spy who steals secrets finds that there is confidential information in the bottle that he wants. He can't wait to extract the cork and take out a note to see what happened. Suddenly the note changes, first from the blue. Slowly darkened, and then the whole sheet of paper actually burned up. The spy immediately took out the note and threw it away. The note sparkled with fiery tinges and turned into a pile of cigarette smoke. This is a shot in many movie blockbusters. With the development of science and technology, such paper that can be burned automatically appears around us. Not only that, but more high-tech integration has given the paper more functions. It will “talk”, “brain”, and not afraid of water. In fact, as long as the paper is inserted into the wings of science and technology, the invention of specialty paper will exceed people's imagination.

Special paper with cultural atmosphere

Color inkjet paper

Color inkjet printing paper is a supporting material for the information industry. The quality of images printed with it is comparable to that of color photographs, and it is widely welcomed by people. With the popularity of computers and printers, the market demand will increase.

The development technology of color ink-jet printing paper is difficult. Although it is manufactured by traditional paper-making and coating processing methods, the base paper, coating pigments, adhesives, and auxiliary chemical aids are all special special products, which are different from conventional paper-making raw materials. Materials still need to be self-synthesized and prepared. Its manufacturing process involves papermaking, printing, computer, chemical and other technical fields, and is a product of cross-cutting applications of edge science. Color ink-jet printing paper is a kind of coating product. The discharge of pollutants in the production process is very small. It is a high value-added paper that is environmentally friendly and worthy of development.

At present, China's color ink-jet printing paper is mainly imported from Japan. Its price is relatively high. After domestically produced color ink-jet printing paper is industrialized, it will produce good social and economic benefits.

Carbonless paper

In 1945, the National Cash Register Co., Ltd. of the United States developed NCR paper, which is not apparently different from plain paper in appearance, but it can be used to reproduce and produce the same effect as blue carbon paper. Stain your fingers. Because it does not use carbon materials, it is called carbonless paper, or carbonless paper for short. The technical principle lies in that chemical coatings containing color formers and color developers are evenly coated on the CB surface and CF surface of carbonless copy paper. Under certain pressure, the microcapsules on the CB surface break, and the coloring solvent overflows. A chemical reaction with the developer on the CF surface gives clear images and text.

Why should carbonless paper be classified as specialty paper?

First of all, the structure of paper is special. Carbonless copy paper is generally divided into upper, middle, and lower pages, and each page has three different layers of structure. This is not what ordinary paper used to have.

Second, the added chemicals are special. For example, carbonless copy paper requires the preparation of microcapsules, the use of leuco dyes, color reagents, etc., whereas plain paper requires only the addition of general chemicals (eg, rosin gum, modified starch).

Again, special processing techniques. The application of carbonless copy paper varies according to different levels and requires multiple coating operations, and the processing difficulty is high. Ordinary paper sometimes does not need to be processed separately.

Finally, the application area is special. Carbonless paper is mostly used in financial and financial, aerospace, electronic communications, defense and military departments.

Carbonless copy paper is a new generation product of today's ink copy paper, which is easy to use, anti-virtual, non-polluting, etc. It is an ideal carbon paper for enterprises and institutions to open financial invoices and sign contracts. It has broad prospects and good economic benefits. The output of carbonless copy paper in China has been growing rapidly. It was 50,000 tons in 1998 and 135,000 tons in 2002. By 2005, production will be estimated at about 250,000 tons.

Sounding Paper Japan's Olympus Optical Industries Co., Ltd. has developed a sound-generating paper that can be heard with a special scanning pen to read fine-grained barcodes printed on paper. The company cooperated with publishing houses and published sounding books. The sound was recorded with a 8.4-mm-thick bar code, and the reader could hear the sound from the headphones.

Nano waterproof paper

This is a paper made of nano-materials. It not only maintains the original writing and copying functions of paper, but also has super-waterproof and moisture-proof properties that ordinary paper does not have, and it can improve the strength of printing surface and reduce the special performance of the expansion and contraction rate. Used to print water-resistant books, long-term preservation documents, military maps, etc. Since its increased cost is only about 10% more expensive than plain paper, the market prospects are promising.

Confidential specialty paper

Anti-copy paper

The so-called anti-copying is to prevent the original copy through the copy machine and the original exactly the same product to achieve the purpose of preventing counterfeiting. Anti-copying paper with hidden texts, patterns, and patterns is printed with a background pattern (a very fine dot pattern or hidden text or pattern) that has almost no effect on reading or recognizing. Once copied, the pattern or Hidden text and patterns clearly appear.

In addition, a Japanese chemical company has developed a “secret paper” called KSP, which is protected by a very thin layer of aluminum plating that biases or scatters the photocopier light. In this way, the copying machine cannot distinguish between the word and the background behind these words. The bronze paper is put into the copying machine. The result is a dark piece of copy.

Smart paper

The French developed a kind of smart paper. In the process of printing documents in the office, a bar code-like logo was added to the paper. These signs can hold 1 Mbytes of information per square inch. Any printer equipped with the correct driver software, You can read out the information in the logo.

Anti-leakage paper

A Canadian company has developed a new type of white paper whose surface has been specially treated so that the confidential information of the document is not copied or passed through a fax machine. To this end, the need for confidentiality, such as individual paragraphs, sentences, numbers, etc., must be separated by a special pen-scriber. The fountain pen is transparent and will produce a complex pattern once it is in contact with the paper surface. This pattern does not prevent reading documents, but it can break the normal work of the copier's sensitive components. Therefore, an ink ribbon will appear after the required confidentiality is copied.

Automatic burning paper

This is the paper that we burn automatically at the beginning of the article. Sweden has developed a new type of confidential paper that will be automatically burned in the safe when the key to the safe is stolen or the safe door is smashed. Therefore, it is very safe to use such paper to print confidential documents and information. Tamper-proof paper France developed a tamper-resistant security paper "Secura". It uses advanced compression printing technology, when the pressure generated by the pen tip, dot matrix printer or letterpress printing on the "Secura" paper, will make the paper fiber inside and the back of the paper chemical reaction, 1 minute later on the back of the paper Marks or text patterns appear on it. On the front side of the paper, there is a layer of chemicals that prevent the documents from being smeared, wiped, scratched, scraped, and color copied. When altered with solvents such as organic solvents, redox agents, acids, and alkalis, the formulation enters the paper fibers and leaves a color mark in it. The surface of the paper is also accompanied by a layer of toner, such as an eraser or a knife, which also produces a color mark on the surface of the paper.

The development and production of specialty paper in China lags behind those of the United States, Japan, and European countries. Overall speaking, it is far from the advanced level in foreign countries. However, in recent years, adjustment and development, optimization and innovation have emerged, and a number of varieties have emerged. Enterprises with special characteristics have strong competitiveness in the domestic specialty paper market, and some products have already begun to export. At present, some varieties of domestic specialty papers have occupied the dominant position in the domestic market, but in some areas of specialty papers with higher technological content and a certain market in China, imported products still dominate.
