The impact of nanotechnology on the packaging and printing industry

release date: Source: Chinese paper industry

among the four great inventions in ancient China, except that gunpowder originated from ancient alchemy, the other three inventions can be attributed to ancient information technology. Papermaking and printing are one of the great breakthroughs and achievements of ancient information technology. It is an important prelude to the arrival of the Renaissance. Marx called it "the three great inventions that herald the arrival of bourgeois society". Qian Xuesen, a famous scientist, believes that "the structures around and below nanometer will be a key point of scientific and Technological Development in the next stage. It will be a technological revolution, which will lead to another industrial revolution in the 21st century." Since its invention, printing has experienced more than 500 years of "lead and fire" and nearly 100 years of "light and electricity", and now it has entered the era of "number and". 20 years ago, Chinese scientists led the Chinese printing industry to bid farewell to lead and fire, usher in light and electricity, remote publishing, color publishing, digital printing systems, bid farewell to paper and pen, and usher in digital and. It has become another milestone for China's packaging, printing and publishing technology to lead the world. In the 1990s, high fidelity printing has quietly come to us, and its point is about um, which shows that printing materials are not far away from the nano level. Today, China's paper industry starts with nanotechnology. Let's introduce in detail the impact of the packaging and printing industry

using nano materials to make printing materials or adding nano materials to printing materials to make nano ink, nano paper, nano printing machine and other nano printing auxiliary materials can greatly improve the quality of printing materials, or produce printing materials with special functions, which can bring another technological revolution after light and electricity to the printing industry

at present, nanotechnology has emerged two methods to create nanostructures, namely "top-down method" and "bottom-up method". So far, all kinds of lithography we have discussed belong to the "top-down method", and the "bottom-up method" is actually a kind of molecular tectonics. The "top-down" method uses a process similar to engraving, such as electron beam printing, which has reached an accuracy close to the atomic level. For quite some time, the "top-down" method is likely to be the preferred method for building truly complex devices. Scanning probe microscopy can meet the requirements of nano printing in terms of resolution, positioning accuracy and manufacturability. Scanning probe microscopy can be used for atomic level printing. It can be concluded that nanotechnology is the result of printing diffusion thinking

nano production technology, especially the preparation of gold "nano dots", is not a new thing. In Medieval and Victorian churches, various colors can be seen on the colorful glass windows; Ancient pottery was painted with different colored glazes, which were based on the nano scale performance of the material, which was different from the macro scale performance. In particular, nano gold powder will show orange, purple, red or dark green according to different scales. In a sense, the first nano technologist was actually a glass technologist in front of the forge in the middle ages, rather than a smart worker in a modern semiconductor factory. Obviously, the glazing workers do not understand why their treatment of gold will make the gold show different colors, but we are now very clear about the mystery of it

the research and development of nanotechnology has formed a new scientific and technological field between chemistry, physics, biology and electronic engineering. It is a science and technology based on many modern advanced science and technology. It is the product of the combination of modern science and technology, which will revolutionize the research and application in the original field and trigger a series of new science and technology, Nanotechnology is integrated into almost all branches of contemporary science and technology. Undoubtedly, nano packaging printing is no exception

application of nanotechnology in the printing industry

printing of new materials. When a special surface processing treatment is adopted, two kinds of two-dimensional surfaces with different properties can be formed on the medium, and the surface area of each phase surface and the "interface" of the two-phase structure are nano-sized, super hydrophilic and super lipophilic interfaces will be generated. It is conceivable that the resolution of printed matter will be higher in the future

due to the development of printing plates, the requirements for inks will inevitably increase accordingly. At present, the technology of producing ultra-fine metal materials "nano in short, nano metal powder" by DC arc plasma has been realized. It is an inevitable trend for nano material engineering to develop from metal and semiconductor fields to diverse organic fields. When an effective preparation method of ultra-fine materials is established and the stability problem commonly existing in organic materials is solved, the performance of ink will surely have a leap. Packaging and printing materials mainly refer to PS board, paper and ink. Due to the characteristics of nanotechnology, their printability will be greatly changed to better match the printing conditions. As we all know, the best roughness range of PS board is nm. It is conceivable that nanotechnology has a great impact on the performance of PS version. The problems of low printing resistance, uneven roughness and the performance of photosensitive solution in printing will be solved with the application of Nanotechnology (1) heating, melting and mixing. Nanotechnology is the latest technology to "create" new packaging with high performance, high efficiency ratio and high functions. Therefore, nanocomposite packaging materials have strong development momentum and broad application prospects. For example, adding 10% nano (thermotropic liquid crystal polymer) to the polymer will effectively eliminate burrs after stretching, and the strength will be increased to 476mpa, thus greatly expanding the use of packaging materials

theoretical basis of nano packaging and printing

nano packaging and printing is a new discipline that intersects and integrates nanotechnology and packaging and printing science. Its theoretical basis includes: (1) nanotechnology must have two conditions: one is nano size; The second is the new physical properties that are not found in nature. (2) There are three kinds of research fields with the strongest function in nanotechnology, namely, nano materials, nano devices, nano detection and characterization. (3) Nanomaterials. After ordinary materials are made into nano scale, there are four unique effects, namely, small size effect or volume effect, surface effect and interface effect, quantum size effect and macro quantum tunnel effect. (4) Nanotechnology route and nano manufacturing are the key technologies to realize nano state. Its tri Mack hybrid panel adopts robot injection molding unit manufacturing in two ways: one is top-down and the other is bottom-up. (5) Nano materials science and nano processing are the two basic disciplines of packaging and printing in nano science

basic concept of nano packaging and printing

definition of nano packaging and printing: Although there is no accurate definition of nano packaging and printing at present, from the perspective of nano science, nano packaging and printing refers to the use of nano materials and nano technology to synthesize, add and modify nano packaging and printing products, so that they have nano structure, scale and specific functions

nano packaging printing has four elements: nano packaging printing material elements, nano packaging container and printing carrier elements, nano packaging printing technology elements, nano packaging printing information elements

nano packaging and printing materials: refers to the system of nano composite packaging and printing materials made of particles or crystals with dispersed phase size of nm and other packaging and printing materials

research objects and tasks of nano packaging and printing: the research contents of nano packaging and printing are: nano packaging and printing technology (preparation method), nano packaging and printing materials, nano packaging and printing structure, nano packaging and printing machinery, nano packaging and printing testing, nano packaging and printing theory, nano packaging and printing market, etc. Study the movement state and law of nano packaging and printing materials in the logistics process, the law of physical and functional changes of nano packaging and printing materials, and the preparation technology; Study the relationship between nano packaging and printing and multidisciplinary, so as to put forward a new concept of packaging and printing, improve and create new packaging and printing technology, packaging technology and decoration technology, and shorten the engineering, industrialization and commercialization process of existing packaging and printing enterprises and nano packaging and printing

impact of nanotechnology on packaging and printing equipment

the ink supply system of the printing machine is an important part to ensure normal printing. The function of ink roller is to transfer ink to the surface of printing plate. Therefore, the choice of ink roller material is very important to the printing quality. The use of nano materials can change the elastoplasticity, oil resistance, acid resistance, solvent resistance, aging resistance, inkiness, transmissibility and wear resistance of the ink roller, so as to stabilize the printing transmission conditions. Similarly, the use of nano materials can improve the quality of printing blanket, thereby stabilizing the printing conditions and improving the printing quality

nanotechnology will also be applied in transmission. For example, the tiny micro motor system (MEMS) can place 1million micro machines on a silicon chip, and each machine has an electronic control system. Texas has used MEMS technology to develop chips that display video images. With such a fine sensor - transmission device installed on the printing machine, the pressure, speed, position and so on can be adjusted and controlled very accurately

the main problem of printing equipment is mechanical accuracy. One is the inherent defects caused by the level of manufacturing technology in the manufacturing process; The second is the failure caused by mechanical wear in the process of printing production. The main components that are easy to wear in printing equipment include: gears, cams, journal and shaft sleeve (or eccentric sleeve) of rollers, etc. With the application of nanotechnology, the accuracy and wear resistance of these key components can be greatly improved, the maintenance cost can be reduced, and the printing quality of printing products can be improved. By using nanotechnology, nano packaging system can be developed. The traditional packaging and printing products will be updated by making various types of additives at the micron level into nano products. At the same time, the nanotechnology industry will promote precision manufacturing technology to the whole packaging and printing industry through the manufacture and application of nano powder and film

target outlook for the industrialization of nano packaging and printing

the share of packaging and printing industry in the national economy has ranked 14th, with an annual output value of more than 300 billion, with an annual growth of about 15%. Undoubtedly, China is already a big packaging country in the world, but it is not a powerful packaging country. The combination of environmental protection, it technology and nanotechnology will be the development direction of this discipline

the focus of nano packaging industry is packaging materials and packaging technology. At present, the research and application of nanotechnology in packaging is still in its infancy. However, nanotechnology is bound to become the "commanding height" in the world packaging field. In the past, most of the advanced equipment, materials and technologies in China's packaging industry were imported. The emergence of nanotechnology will bring opportunities for the development and technological innovation of China's packaging industry. We must speed up the process of technological innovation and strive to be in the forefront of the world. Nano will fulfill my dream of becoming a powerful packaging country
