Photocatalytic ARC-FLASH has three major effects:
sterilization, deodorization and antifouling.
Sterilization and deodorization effects are
achieved by the strong oxidative decomposition power. Antifouling
is the effect of oxidative decomposition and super-hydrophilicity.

To put the photocatalyst shown in the figure at left to practical
use in living spaces, it is important to stabilize the titanium dioxide
photocatalyst effectively and to bind it to the material to be coated.
The difficulty of binding with materials is a characteristic of titanium
oxide. ARC-FLASH has enabled this difficult binding. |

As shown in the figure above, when UV rays
are applied to a surface treated with ARC-FLASH, photoexcitation
of titanium dioxide occurs and all the organic
matter that comes into contact with the surface is decomposed
into low molecular weight molecules. Not even dead bacteria
remain on the surface. Substances that cause fouling are also
decomposed on the same principle, and super-hydrophilicity prevents
drops of water from adhering to the surface. In case of outdoor
application, the surface is washed by rain and cleanliness
can be maintained at all times.

The figure at left shows decomposition in the case of acetaldehyde,
which is responsible for cigarette odors.
Acetaldehyde is decomposed into carbon dioxide and water vapor, and
the smell is eliminated. The better the air circulation, the greater
the deodorizing effect. In the same way, airborne bacteria and viruses
are reduced by air circulation. As long as ultraviolet rays are applied,
the condition shown in the figure will be maintained. |
