Nuclear track anti-counterfeiting is a high-tech and high-tech technology. Together with “heavy ion micropore anti-counterfeitingâ€, it is called two nuclear weapons in the field of anti-counterfeiting. It has now begun to be widely used in many aspects such as badges, trademarks, tickets, etc. It can be said that it is a trend to guide today's and future security development.
Nuclear Track Anti-Counterfeit Principle
It uses nuclear reactors and other nuclear materials to irradiate plastic films to produce track damage in the plastic film, and then forms the fine-grained microtrack anti-counterfeit pattern required by the imaging technology to identify the trademark. Finally, after the late commodity processing, micropore anti-counterfeit signs or other forms of nuclear track micropore anti-counterfeiting technology products are obtained.
The nuclear track anti-counterfeiting technology products can carry out multiple identifications, improve the reliability of ordinary identification, and have first- and second-line anti-counterfeiting features. The first-line ordinary anti-counterfeiting device has the advantages of simple, rapid, and effective recognition. There are three main ways to identify:
(1) Use the permeability of the microchannels for anti-counterfeiting identification. The pattern of anti-counterfeit marks on nuclear tracks is smeared with liquids such as water and wine. Since the channels are filled with liquid, the optical structure of the film changes, and the pattern becomes lighter or even disappears. If a pattern is printed on the back of the pattern, it becomes more pronounced. Once the liquid evaporates, the pattern is restored. If pens, ballpoint pens or other colored pens are used to draw on the anti-counterfeiting mark, the white paper backed by the pattern part of the mark will leave a corresponding color due to the ink penetration, and in the part where the mark is not patterned, there will be no slightness. Hole without leaving any color.
(2) Use the adsorption of the channel to identify forgery. Also use the above method to detect, with a pen, ballpoint pen or other colored pen on the anti-counterfeit logo painted, wipe the surface color, because the color penetrates into the micro-hole, the color left in the anti-counterfeit logo pattern part can not be removed in a short time, In the absence of a pattern part of the security mark, it can be immediately removed.
(3) Use high magnification magnifiers for security identification. Using the 20 times magnifying glass to carefully observe the pattern part of the anti-counterfeiting mark, it can be seen that it is composed of irregular points, and has unique features for identification of anti-counterfeiting and nuclear track anti-counterfeiting, and is characterized by simple identification equipment.
The nuclear track anti-counterfeiting mark was torn off and observed under an optical microscope at a depth of more than ten micrometers. A nuclear track anti-counterfeit mark made of a plastic film was observed. The mark part of the mark was composed of micron-sized micropores formed by nuclear tracks. The pore size and pore density of the micropores can be changed according to user requirements. The pore size is cylindrical and the pore distribution is random. Nuclear track anti-counterfeiting marks produced by nuclear reactors are randomly distributed at certain discrete angles. The pattern is very delicate, it can not change the user-supplied pattern, and the product price is moderate. In 2001, the nuclear track anti-counterfeiting technology has been listed by the Ministry of Science and Technology as a national key science and technology promotion project.
The key to nuclear track anti-counterfeiting technology is the production and anti-counterfeiting technology of the nuclear hole film (ie, nuclear track anti-counterfeiting protection film). It utilizes selective irradiation and etching to form a nuclear pore film on the plastic film to form a specific pattern. Its anti-counterfeiting principle is:
(1) The manufacture of nuclear membranes requires cutting-edge nuclear technology and expensive nuclear facilities. They are all controlled at the national-level large-scale nuclear branch research units. Under the supervision of the National Nuclear Safety Administration, counterfeiters are difficult to obtain. Even if the manufacturing process of the film is disclosed in the future, it is extremely unlikely that it will be forged due to production conditions.
(2) Nuclear reactors for the manufacture of nuclear track anti-counterfeiting membranes are not conventional production reactors, but special reactors that must be equipped with irradiation tunnels. The reactors of nuclear power plants cannot be manufactured.
(3) The manufacture of nuclear pore membranes requires high-quality scientific and technical personnel, high-energy physics and nuclear technology, and only a few countries in the world have mastered it. specialty.
(4) The hole of the anti-counterfeiting mark film has a certain scattering angle distribution and is not easy to imitate.
Due to the random distribution of the nuclear track micropores on the film, the direction of the micropores was irregular and could not be imitated by mechanical processing. It was also impossible to form holes with a diameter of 5 microns by laser drilling. With chemical methods, it is impossible to process micro-hole patterns with a hole density of 40,000 to 1,000,000 holes per square centimeter, and it is even less likely that the processed pattern will have the function of what color is changed to what color is applied, so that security against forgery can be guaranteed.
The nuclear track mark film is generally formed by pressing a piece of nuclear track protection film and a trademark, and the logo and the text under the film can be easily seen through the white protective film, so that the consumer can easily identify the brand of the product. To identify the authenticity, just apply a little water to the membrane (saliva can also be used). The water immediately penetrates through the protective film to the logo area under the film to make the pattern clearly visible. Consumers can also apply ink or pigment to the film. After tearing the film, it can be seen that ink and pigment have penetrated the pattern. The counterfeit white semi-packing machine 'target=_blank' transparent film does not have the above characteristics because it does not have high-density micropores.
Nuclear Track Anti-counterfeit Market Outlook
Nuclear track integrated anti-counterfeiting technology
It is a Beijing high-tech torch development company using high technology, after many years of successful research. It integrates a number of anti-counterfeiting technologies such as "nuclear track" technology and aluminized film brittle encryption, and it is a new type of anti-counterfeiting technology that is synthesized on a security label by high technology. According to experts, it has a high technological content, it is difficult to imitate, easy to identify, a large number of low production costs, and good communion with other technologies. This technology can be applied to all objects that can stick anti-counterfeiting labels, such as audio and video products, books, cigarettes, alcohol, and high-end branded products.
Nuclear track nuclear track dual-card anti-counterfeiting technology
This technology uses the nucleus or heavy-charged particles to form different tracks when a solid material is injected at a certain speed. The track is taken up to make a printing plate, which is pressed into a laser holographic anti-counterfeiting mark, and then the mark is divided into two. Half is stored in the computer and the other half is affixed to the product. When the test is performed, a computer identification device is used to identify the nuclear track in the laser image, and the counterfeit sign immediately appears. The key is the plate making technology, which no one can imitate. This technology can be processed into dual-card track anti-counterfeiting film and dual-card track security paper.
Improvement of nuclear track anti-counterfeiting technology
(1) The biggest drawback is that the security mark can be reused. As can be seen from the above-mentioned several identification methods, the identification method of identification does not destroy the micro-holes, and as long as it is cleaned, it can be used again. This opens a great deal of convenience for the counterfeiters and only needs to be recycled. Marks that have already been used on goods can be falsified.
(2) Do not rule out that those grouped fraud organizations have the possibility of manufacturing equipment, because the hospital's X-ray machines and nuclear radiation detection in industry all require nuclear radiation materials.
(3) As a filter material, the nuclear pore membrane is relatively easy to buy. The pores of the nuclear pore membrane are approximately evenly distributed. If some technical measures are taken to close a part of the pores of the nuclear pore filtration membrane, a specific distribution can also be obtained. Patterned nuclear pore membrane.
(4) The nuclear pore membrane is actually a kind of microporous membrane, and it is possible to stimulate the activity of the macromolecule at the bombardment by bombarding the polymer membrane with a laser or high-energy electron beam, and similar micropores can be obtained under certain chemical etching conditions.
In short, nuclear track anti-counterfeiting technology has become a new star in today's anti-counterfeiting field. Although there are still some deficiencies, but with continuous development of science and technology and continuous improvement of technology research, it will surely become an excellent anti-counterfeiting technology.
