Light purification tiles come out

The "ray purification tile" jointly developed by the Taiwanese merchant Roman tile and the Institute of Photocatalysis of Fuzhou University in September 2003 coated various organic contaminants on the surface without any wiping, but only in the sunlight. After five minutes of exposure, it can be as white as new.
Roman tile chairman Huang Jie recently displayed the new product at the Haiyan Roman Brick Factory in Zhejiang: When using this type of tiled building, the future will never need to spend money on high-floor cleaning companies to scrub the exterior walls; If the external wall of the rain stains is exposed to the ultraviolet rays of the sun, organic stains will naturally decompose, and the remaining non-organic pollutants will naturally be washed as soon as they meet with rain, and the building will always look like new.
The chemical principle of this new invention is to use nanotechnology to first ultrafine the titanium oxide, and then combine it with the glaze of the tile-made magnetite and tile surface to form a “light-purifying tile”. The titanium oxide Chemical changes caused by ultraviolet irradiation can decompose and volatilize organic substances on the surface, giving the tiles a "self-cleaning" effect. This decomposition and volatilization is not only completely harmless to the human body, but even the air within a few hundred meters around can produce a purifying effect. According to the data provided by Fuzhou University, the ability of 1,000 square meters of light-purifying tiles to clean the nitrogen oxides and sulfides in the air in the sunlight is equivalent to the photosynthesis of 70 poplar trees at the same time. The new Roman tile product has now received orders for several buildings in Shanghai and Japan. The factory is actively mass-producing and the first delivery in August.
The selling price of tiles is about RMB 120 per square meter. Although it is higher than other series of external tiles of Roman tiles, it can save users the countless external wall cleaning fees and keep the exterior of the building clean forever. At the same time, the surface of the light purification tiles The generation of a large amount of active oxygen can be antibacterial and deodorizing, and it also contributes a lot to the purification of the surrounding environment.
