This is a case study of photocatalytic application for anti-contamination measures of LP gas tanks.

The decomposition of organic contaminants using photocatalysts and self-cleaning will break down the substances causing dirt and mold in LP gas tanks, resulting in a clean state.

■Titanium Dioxide Raw Material By coating a titanium dioxide aqueous solution, which serves as the raw material for photocatalysts, on the ceilings and walls of buildings, it exhibits effects such as dirt resistance, deodorization, antibacterial properties, antiviral properties, and mold prevention. ■Indoor Photocatalyst When light hits the surface of the indoor photocatalyst, reactive oxygen species are generated on the surface, decomposing organic substances that cause dirt and odors into water and carbon dioxide, rendering them harmless. ■Outdoor Photocatalyst When rain hits the surface of the outdoor photocatalyst, a hydrophilic effect causes water to spread thinly beneath the dirt, contributing to self-cleaning as the dirt flows away with the water, thus maintaining the building's aesthetics and reducing cleaning costs. ■Duration of Photocatalytic Effect Since titanium dioxide, the raw material for photocatalysts, is inorganic, it does not degrade due to ultraviolet light or other factors, and the effect continues for a long time as long as the coating substrate's paint surface or wallpaper does not peel off. A glass coating on floor tiles creates a strong water-repellent surface. The water-repellent effect prevents the penetration of waste water such as urine, making it easier to remove dirt and reducing odors caused by bacteria and other sources.
