PhotoCatalyst Information
Strong
Oxidation Power
Hydroxyl
radicals are among the strongest oxidizing species, even much stronger
than chlorine, ozone, and peroxide. They act as very powerful disinfecting
agents by oxidizing the cells of microorganisms, causing rupture
and leakage of vital composition.
Deodorizing
VOC
and Odor Remediation |
Sterilizing
Anti-Bacterial
and Mold Prevention |
| On
the deodorizing application, the hydroxyl radicals accelerate
the breakdown of any Volatile Organic Compounds or VOCs by destroying
the molecular bonds. This will help combine the organic gases
to form a single molecule that is not harmful to humans thus
enhance the air cleaning efficiency. Some of the
examples of odor molecules are: Tobacco odor, formaldehyde,
nitrogen dioxide, urine and fecal odor, gasoline, and many other
hydro carbon molecules in the atmosphere.

Titanium
dioxide has strong oxidation affects to single-celled organism
that includes all bacteria and fungus. The very strong oxidizing
power of Titanium Dioxide can destroy bacteria's cell membrane,
causing leakage of the cytoplasm, which inhibits bacteria’s
activity and ultimately results in the death and decomposition
of bacteria. Generally speaking, disinfections by titanium oxide
is three times stronger than chlorination, and 1.5 times stronger
than ozonation.

Super
Hydrophilic Property
Self-Cleaning,
Anti-Soiling and Anti-Fogging |
The
hydrophilic nature of titanium dioxide, coupled with
the gravity, will enable the dust particles to be swept away
following the water stream, thus making the product self-cleaning.
When
the surface of photocatalytic film is exposed to light, the
contact angle of the phtocatalyst surface with water is reduced
gradually. After enough exposure to light, the surface reaches
super-hydrophilicity. In other words, it does not repel water
at all, so water cannot exist in the shape of a drop, but
spreads flatly on the surface of the substrate. And
the water took the form of a highly uniform thin film, which
behaves optically like a clear sheet of glass.
Most of the
exterior walls of buildings become soiled from automotive
exhaust fumes, which contain oily components. When the original
building materials are coated with a photocatalyst, the dirt
on the walls will wash away with rainfall, keeping the building
exterior clean at all times. |
