Nanometer materials for screen printing industry brought the Gospel and change

Now nanomaterials has been gradually penetrate thesilk screen printing ink manufacturing, has great advantages in raising thequality of printing. Although the process is not yet mature, but expertspredict that the popularity of nanomaterials will be impacted to printing.

 As is known to all, ink fineness has closerelationship with quality of printed matter. Ink fineness better and strongercolouring, print outlets are clear and forceful. Because of nanometer materialsis currently the most fine grain materials, nano ink has special advantage infineness.

 Conductive nanoparticles due to significantquantum size effect and surface effect, and the absorption of light show somecharacteristics. Experiments show that some of the light absorption edge of thenanoparticles is an obvious blue shift, some light absorption edge of thenanoparticles was substantial redshift. Accordingly, if add them to the yellowand cyan ink made in nano ink, can improve its purity. Add a particular nanoparticles of nano ink used in color printing, color level will become moreabundant, order will be more bright, is similar to the plasma technology isused in television screens, can largely improve the image of expression.

  Because of nanometer metal particles canabsorb all the light waves and make themselves appear black, light scatteringand at the same time, therefore, also can add nano metal particles to blackink, in order to improve its purity and density.

In addition, because the nanometer particles has good surface wettability,their adsorption on ink pigment particles in the surface, can greatly improvethe ink oil-wet and wettability, and can guarantee the stability of the inkdispersed system. So, with nano particles of nano ink, printing performance canget a bigger improvement.

  Of ink components (such as resin,pigments, fillers, etc.) also can be made into nanoscale materials, becausethey are highly subtle, and has good mobility and lubricity, can achieve betterdispersed suspension and stable effect. Add nanoscale materials to differentUSES different kinds of printing ink, can get different result. If used in uvink, can accelerate the curing speed, and eliminate the contraction of the inkmembrane wrinkling; Nanoscale with conductive carbon ink, if add ink can bemade of conductive ink; In glass ceramic ink, if the inorganic materials isnanoscale fineness, will be able to save a lot of raw materials.

Nanoscale materials, as well as some specific if added to ink, can achievecertain results. Such as the nano al2o3, inorganic nano material has goodliquidity, if add to the ink can greatly improve the wear resistance. When somesubstances at the nanoscale, different colors have different particle size, andit can make our color ink manufacturing is no longer dependent on chemicalpigments, but selecting the appropriate volume of different nanoparticles torender different colors.

  Nano ink can also be used for theluminous graphic printing. Some nanoparticles itself have shine group, canshine. With ink printed with the particles added the illuminate of printingquality does not need external light source, by their own light can be thehuman recognition. If this ink is used for large outdoor advertising prints orgraphic print to reading at night, no longer need to external light source, notonly can save energy, also greatly facilitate the users.
