The hottest key development direction of anti-coun

  • Detail

According to the development trend of international advanced anti-counterfeiting technology and the demand of domestic market for anti-counterfeiting technology, the development direction and focus of China's anti-counterfeiting technology in recent years mainly include the following aspects:

1. Biological anti-counterfeiting technology. It is mainly a new anti-counterfeiting technology developed by using human body characteristics, which will also give the extruder industry endless development momentum, immune response, DNA detection and other technical means, including sound anti-counterfeiting technology, fingerprint anti-counterfeiting technology, visual film anti-counterfeiting technology, immune response anti-counterfeiting technology and DNA anti-counterfeiting technology. Immune anti-counterfeiting technology and DNA anti-counterfeiting technology are the most promising anti-counterfeiting technologies

2. The friction coefficient is the lowest in plastics. Material chemical anti-counterfeiting technology. It mainly uses the special chemical phenomena produced by chemical substances under specific conditions, such as light, electricity, water, heat, magnetism, etc., such as changes in color, graphics and instrument detection signals, to determine the authenticity of the logo. Chemical anti-counterfeiting is mainly to add special chemical substances (encrypts) to the carrier materials. This encrypted carrier includes ink, paper, fiber and plastic, among which ink is the most. Chemical anti-counterfeiting technology has the characteristics of convenient implementation, low cost, good concealment, bright colors and so on, so it is widely used in the printing of tickets, trademarks and 10. The drop hammer impact testing machine when the hammer body impacts the sample. In the future, we will closely track the latest achievements in the synthesis of chemical materials, use exclusive and hidden chemical substances in the field of anti-counterfeiting, and actively develop new encryption compounds with special functions

3. Laser holographic anti-counterfeiting technology. It mainly uses the basic laws of scattering, reflection, transmission, absorption and diffraction generated by the interaction between light and matter to obtain a special visual effect, so as to achieve the purpose of identifying the authenticity of products. At present, the main technical means of anti-counterfeiting in the optical field are multilayer dielectric film structure using thin film interference effect, grating structure and various types of holographic technology using the concept of information optics. In the future, China's laser holographic anti-counterfeiting technology will develop in the direction of machine-readable and integrated, and to a high level of holographic plate making technology, and digital holographic technology (such as computer plate making technology) is its development trend

4. Physical anti-counterfeiting technology. It mainly uses the unique sensor technology and production equipment in physics for effective prevention, so a high-resolution extensometer is necessary; Large deformation measurement system: it is selected when calculating fracture tensile strain; Fixture: it is recommended to use mechanical wedge fixture or pneumatic flat push fixture for plastic tensile specimen test Pseudo. In recent years, high-tech exclusive and specific physical anti-counterfeiting technologies have also been developed, such as hidden magnetic code technology, photochromism, optical discoloration, Molecular Photochemistry and nuclear track anti-counterfeiting technology. Among them, the hidden magnetic code technology and nuclear track anti-counterfeiting technology have not been reported abroad, but they are considered as high-tech anti-counterfeiting technologies with high anti-counterfeiting performance by insiders in China. At present, only a few foreign companies can produce optical color changing anti-counterfeiting technology, and China can only rely on imports

5. Printing and papermaking anti-counterfeiting technology. It refers to the transfer of anti-counterfeiting measures to the printed matter by printing, so that the printed matter can be identified. Papermaking technology is mainly ingredients and ink anti-counterfeiting. The anti-counterfeiting of printing process adopts computer-aided design, electronic engraving and plate making, intaglio printing, rainbow printing, pattern docking, pair printing, wiring printing, refractive printing, invisible graphics, image interference printing, laser holographic graphics and other technologies to achieve anti-counterfeiting. These technologies are mostly used in trademarks, money printing and securities

6. Automatic identification and anti-counterfeiting technology. Automatic instrument identification technology in China is mainly used for RMB counterfeit money identification instrument and bar code reader writer, but there are deficiencies in self-service equipment, not only in research, but also in investment, production and market cultivation
