The characteristics and advantages of full contact nano ink

nanotechnology was born and rose rapidly in the late 1980s. It can be said that it has developed to a hot point. It seems that it has become a popular new term that everyone can blurt out. But really speaking, what is nanotechnology? Many people may not be able to answer Identification of true and false -- thousands of commodity identification methods

nano is the translation of English nano meter. One nano meter is one billionth of a meter. It is only 45 atoms long. Nanostructures usually refer to micro structures with a size of less than 100 nm. The basic meaning of nanotechnology is to understand and transform nature within the scope of nanostructures, and create new substances through direct operation and arrangement of atomic and molecular motion laws and characteristics. This means that people can use this technology to produce extremely pure materials and colorful new products. At present, the research on nanotechnology mainly focuses on nano materials. Nano materials refer to materials with grain size in the range of 1 ~ 100 nm

characteristics and advantages

nano materials have now begun to penetrate into various fields, including the ink manufacturing field of our printing industry. In 1994, Xmx company in Massachusetts of the United States successfully obtained a patent for nano-sized uniform particle raw materials used for manufacturing inks. Nano scale transparent iron oxide series pigments, which have recently been rated as national key new products by the Ministry of science and technology, have also been successfully developed

then, what is the application value of nanotechnology in ink manufacturing? What are the characteristics of nano ink compared with ordinary ink

it is well known that ink fineness is closely related to the quality of printed matter. The better the fineness of the ink, the stronger the coloring power, and the clearer and fuller the dots of the printed matter. Nano ink undoubtedly has special advantages in fineness, because nano materials are the materials with the finest grains at present

because nano metal particles can absorb all light waves and make themselves appear black, they can also scatter light. Therefore, nano metal particles can be added to black ink to improve its purity and density. In addition, semiconductor nanoparticles exhibit certain characteristics of light absorption due to the significant quantum size effect and surface effect. Experiments show that the light absorption edge of some nanoparticles has an obvious blue shift, and the light absorption edge of some nanoparticles has a large red shift. Accordingly, if they are added to yellow and cyan inks respectively to make nano inks, their purity can be improved. Nano ink with specific nano particles added for color printing will have richer color levels and sharper tones, which is similar to plasma technology used for TV display screen, and can greatly improve the expressiveness of images

in addition, because nano particles have good surface wettability, they are adsorbed on the surface of pigment particles in the ink, which can greatly improve the lipophilicity and wettability of the ink, and ensure the stability of the whole ink dispersion system. Therefore, the printing performance of nano ink with nano particles can be greatly improved

we can also make various components in the ink (such as resin, pigment, filler, etc.) into nano raw materials, because they are highly fine and have good flow and lubricity, which can achieve better dispersion, suspension and stability

different effects will be achieved when nano raw materials are added to different types of inks for different purposes. If used in UV ink, it can accelerate its curing speed, and release after cleaning to eliminate the shrinkage and wrinkling of the ink film; Nano carbon ink has conductivity. If ink is added, it can be made into conductive ink; In the printing ink of glass ceramics, if the inorganic raw material composition is nano fineness, a lot of raw materials can be saved

there are also some specific nano materials. If they are added to the ink, they can achieve some specific effects. Inorganic nano materials such as nano Al2O3 have good fluidity. If they are added to the ink, the wear resistance can be greatly improved. When some substances are at the nanometer level, the particle size is different and the color is different, which can make our color oil printing test report ink manufacturing no longer depend on chemical pigments, but choose different nano particles of appropriate volume to present different colors

what is more wonderful is that nano ink can also be used for luminous graphic printing. Some nanoparticles have their own light-emitting groups and can emit light by themselves. The printing products printed with the ink added with such particles do not need the irradiation of external light sources, and can be recognized by the human eye by self illumination. If this kind of ink is used for large-scale outdoor advertising spray painting or graphic printing for reading at night, it will no longer need external light sources, which can not only save energy, but also greatly facilitate users

development and application

the application of nanotechnology in the development and production of ink has made gratifying achievements, especially in anti-counterfeiting ink. Combining nano technology with anti-counterfeiting technology, the developed nano anti-counterfeiting printing ink for removing the dial glass not only has good printing effect, but also can further improve the anti-counterfeiting effect and anti-counterfeiting performance. For example, if you still have other questions about fluorescent anti-counterfeiting oil, the anti-counterfeiting function of inks is lost due to poor light resistance and the anti-counterfeiting mechanism has been decoded. The performance of the nano anti-counterfeiting ink successfully researched by Guangzhou University has reached a satisfactory level in terms of reliability, safety, stability and aging resistance. At present, the product has been used in high-tech fields such as outer packaging, ticket anti-counterfeiting and infrared sensors

at present, we are basically at the stage of talking on paper about nano ink, which is still a long way from being widely used in ink manufacturing and printing industry. However, some experts predict that nano ink will open up a broad Xintiandi for the ink manufacturing industry and bring a new change to the world's ink and printing technology
