Nano ink full contact

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

nano is the translation of English nano meter. One nanometer is one billionth of a meter, which is only as long as 45 atoms. 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 is mainly in the aspect of nano materials, which refers to substances with grain size in the range of 1 ~ 100 nm. Characteristics and advantages

nano materials have now begun to penetrate all fields, including the ink manufacturing field of our printing industry. In 1994, Xmx company in Massachusetts, USA, has successfully obtained a patent for nano-sized uniform particle raw materials for ink manufacturing. 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

as we all know, ink fineness is closely related to print quality. 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, at the same time, they can 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 have proved that the light absorption edge of some nanoparticles has obvious blue shift. The friction and wear experimental machine of Jinan new era Gold Testing Instrument Co., Ltd. is based on the principle of time production by the manufacturer, and the light absorption edge of some nanoparticles has a large red shift when placed in a dry place. 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 clearer tones, just like plasma technology used in TV screens recently, which can greatly improve the expressiveness of images

in addition, because nanoparticles have good surface wettability, they adsorb 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

when nano raw materials are added to different kinds of inks for different purposes, different effects will be achieved. If used in UV ink, it can accelerate its curing speed and 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 will be saved

there are also some specific nano materials, which can achieve some specific effects if added to ink. Inorganic nano materials such as nano Al2O3 have good fluidity, which can greatly improve the wear resistance if added to the ink. When some substances are at the nanometer level, their particle sizes are different and their colors are different, which can make our color ink manufacturing no longer rely on chemical pigments, but choose different nanoparticles of appropriate volume to show different colors

what's 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 printed matter printed with the ink with such particles does not need the irradiation of external light sources, and can be recognized by the human eye by its own light. If this kind of ink is used for outdoor large-scale advertising spray painting or graphic printing for night reading, 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 inks has achieved gratifying results, especially in anti-counterfeit inks. The nano anti-counterfeiting printing ink developed by combining nano technology and anti-counterfeiting technology not only has good printing effect, but also can further improve the anti-counterfeiting effect and anti-counterfeiting performance. For example, in view of the poor light resistance of fluorescent anti-counterfeiting inks and the fact that the anti-counterfeiting mechanism has been decoded and the anti-counterfeiting function has been lost, the performance of the nano anti-counterfeiting inks absorbed by near-infrared ray successfully studied 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 in the stage of talking on paper about nano ink, and there is still a long way to go before we widely replace springs for the 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
