Nano ink guided printing quality

research shows that after the surface of nano semiconductor particles is chemically modified, the media around the particles can strongly affect their optical properties, which is manifested as red shift or blue shift in the absorption spectrum. The experiment shows that the light absorption edge of CDs nano particles has obvious blue shift, and the absorption edge of TiO2 nano test machine has a large red shift when the oil return pipe is injected and vibrated during loading. Accordingly, if they are added to yellow and cyan inks respectively to make nano inks, their purity can be improved. Using nano ink added with specific nano particles to copy and print color prints, the layers will be richer, the tone will be more distinct, and the fine image will have a greater ability of saving performance in the process of processing and using functional plastics

nowadays, with the help of high and new technology, various components in ink (such as resin, pigment and filler) can be made into nano raw materials. In this way, it has good flow and lubricity due to its high fineness, which can achieve better dispersion, suspension and stability, less pigment consumption, high hiding power, good gloss, fine resin particle size, continuous, uniform and smooth film formation, thin film layer, and clear printing image. If used in UV ink, it can accelerate the curing speed, and eliminate the shrinkage and wrinkling of the deinking film due to the fine and uniform dispersion of the filler. In the printing ink of glass ceramics, if the inorganic raw materials are composed of nano fineness, a large number of raw materials can be saved and a more precise, beautiful and high-quality image can be printed. This has brought a great change to the ink manufacturing industry, making it no longer rely on chemical pigments, but choose appropriate volume of nanoparticles to present different colors. Because some substances have different particle sizes and colors at the nanometer level, or different substances have different colors. For example, TiO2 and sio2z are white in nanoparticles, Cr2O3 is green and Fe2O3 is brown. In addition, inorganic nano materials such as nano Al2O3 have good fluidity. If they are added to the ink, the wear resistance of the ink film can be greatly improved. Nano carbon ink is conductive and has a good shielding effect on static electricity to prevent the interference of external static electricity. If it is added to the ink, it can be made into conductive ink, large capacity integrated circuit, modern contact panel switch, etc. In addition, in the conductive ink, if AG is made into nanometer level instead of micron level AG, 50% of Ag powder can be saved. This conductive ink can be directly printed on ceramics and metals. The ink layer is uniform and smooth with good performance. If Cu and Ni materials are made into ultrafine particles of 01-1um, it can replace precious metals such as palladium and silver to conduct electricity. Therefore, the combination of nanotechnology and anti-counterfeiting technology will open up another broad world of anti-counterfeiting ink

in addition, some nano particles have their own light-emitting groups and may emit light by themselves, such as [- N 3H - "nano particles. The printing products printed with the ink added with such particles do not need the irradiation of external light sources. They can be recognized by the human eye by their own luminous recognition. They can also achieve good results for anti-counterfeiting printing. The graphic and graphic printing products used for large-scale outdoor advertising spray painting or night reading do not need external light sources, which can not only control energy, but also greatly facilitate users

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 printability of nano ink with nano particles can be greatly improved. It is believed that with the further development of nano material technology, more nano materials with different characteristics will be known and used by people

in electrostatic copying, using magnetic nano toner to replace the widely used non-magnetic toner can eliminate the need to add ferromagnetic particles to the non-magnetic toner as a carrier, and make a single component copy developer, which can save raw materials and improve the copy quality

to the source of nanomaterials. In fact, there are many methods to obtain nano materials, including high-temperature sintering (such as the sintering technology of carbon nanotubes), precipitation, high-temperature dissolution, chemical vapor condensation or modern plasma energy polymerization
