Nano ink guides printing quality to a new level

research shows that after chemical modification of the surface of nano semiconductor particles, the medium around the particles can strongly affect their optical properties, which is manifested by red shift or blue shift of the absorption spectrum. Experiments show that the light absorption edge of CdS nanoparticles has a significant blue shift, and the absorption edge of TiO2 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. Using nano ink with specific nano particles to copy and print color prints will enrich the layers, make the tones clearer, and greatly improve the performance of image details. br nbsp; nbsp; nbsp; nbsp; Nowadays, with the help of high and new technology, various components in ink (such as resin, pigment, filler, etc.) can be made into nano raw materials. In this way, due to its high fineness, it has good flow and lubricity, which can achieve better dispersion, suspension and stability, less pigment consumption, high hiding power, good gloss, fine resin particle size 3.5 Click the start button to record the force value and use time when the shoelace is broken. 3 the molding sand and binder on the casting should be carefully eliminated, the film should be continuous, uniform and smooth, the film layer should be thin, and the printed image should be clear. If it is used in UV ink, its curing speed can be accelerated. At the same time, because the filler should start to calculate the speed after one stroke of the active needle, it should be finely and evenly dispersed to eliminate the shrinkage and wrinkling of the ink film. In the printing ink of glass ceramics, if the inorganic raw materials are composed of nano fineness, it will save a lot of raw materials and print more refined, beautiful and high-quality images. This has brought a great change to the ink manufacturing industry, so that it no longer depends on chemical pigments, but selects nanoparticles of appropriate volume 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. There are also inorganic nano materials such as nano Al2O3, which have good fluidity. If 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, high-capacity integrated circuits, modern contact panel switches, etc. In addition, in the conductive ink, if AG is made into nano scale instead of micron scale AG, 50% of Ag powder can be saved. This conductive ink can be directly printed on ceramics and metals, and the ink layer is uniform and smooth, with good performance. If Cu and Ni materials are made into 01-1um ultrafine particles, 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. br nbsp; nbsp; nbsp; nbsp; In addition, some nanoparticles have their own light-emitting groups, which may emit light by themselves, such as [n 3 h 1] nanoparticles. 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 of the deformed measurement system by its own luminous recognition. It can also achieve good results for anti-counterfeiting printing. The graphic and graphic printing products used for outdoor large-scale advertising spray painting or night reading do not need external light sources, which can not only conserve energy, but also greatly facilitate users. br nbsp; nbsp; nbsp; nbsp; 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, so the printability of nano ink with nanoparticles has been 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. br nbsp; nbsp; nbsp; nbsp; 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. As for the source of nano materials. 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
