Japan uses titanium dioxide to make decorative tiles

The University of Tokyo in Japan recently successfully developed decorative bricks with self-cleaning functions, which solved the problems of toilet and Kitchen cleaning and disinfection.
This new type of tile uses rare earth technology to spray titanium dioxide onto the tile surface through a special process. The physical and chemical adsorption of titanium dioxide to water is greater than the adsorption of oil, ie, it has both hydrophilicity and oil repellency. Therefore, it is very easy to remove the oil adhering to it. No detergent is needed and no artificial and The machine is scrubbed and only rinsed with water to allow the oil to fall with the water droplets. Titanium dioxide can also undergo certain chemical reactions under ultraviolet radiation, producing a kind of "active oxygen", and active oxygen can decompose organic matters. Using this method, dirt on the surface of the tiles can be quickly removed and the bacteria can be killed.
In addition to ceramic tiles, the above materials can also be used as exterior wall paints, and are particularly effective in eliminating some hard-to-erase stains, such as air pollution. If the exterior of the building is painted in advance, these stains will be difficult to form. Even if it does happen, a heavy rain will make the building look new.
