Definitions

  • the present invention relates to an apparatus for applying a nanostructured material onto articles, in particular tiles, glass and the like.
  • the titanium dioxide is obtained by spontaneous oxidation or, in order to make the thickness controllable, by anodization.
  • Such a compound is usually amorphous, however, operating in very particular anodization conditions, it is possible to obtain crystal oxygen, maintaining the aesthetic properties of the anodized titanium dioxide.
  • the crystal oxygen can assume various microstructures (for example rutile, anatase, brookite) .
  • the anatase presents the most relevant antibacterial and anti-polluting properties.
  • the titanium dioxide is a semiconductor material, stable to the light and to corrosion processes, which in the colloidal form or in . thin film reacts to the radiation of wavelength lower than 430 nm (UV spectrum) . Due to this reaction, called photocatalytic process, the organic, inorganic substances and the bacteria which deposit on the film, are decomposed and removed at room temperature as a result of irradiation of natural and/or artificial light.
  • Hydrogen peroxide and OH radicals produced locally as the results of the oxidation and reduction processes, trigger oxidizing processes, which lead to the mineralization of organic pollutants, to the denaturation of the bacteria and to the neutralization of inorganic toxic compounds, such as Nox.

  • An operational group 67 is placed downstream of the first station 50 and includes a second station 60 and a third station 70, described in the following.
  • the second station 60 situated downstream of the first station 50, provides for the gelation of the liquid precursor 10 applied previously to each tile 1.
