Nano TiO2antibacterial coating - 2020年03月18日(水)
Antibacterial ceramic tiles and sanitary ceramics coated with nano-TiO2film have been industrially produced in Japan, and are mainly used in hospitals, food processing industries etc. However, the development and application of nanotechnology has solved these problems. Through the photocatalysis of nanoparticles, nano-TiO2can directly decompose organic or inorganic toxic pollutants under sunlight or ultraviolet light, and the pollutants can be completely mineralized or oxidized into harmless CO2and H2O without causing secondary pollution. Nanotechnology has shown great potential for the degradation of nitrogen oxides and other organic matter in wastewater.
In addition, it is also necessary to consider the compatibility of the antibacterial agent with the resin, so the antibacterial agent is usually pretreated by adding a coupling agent or a dispersing agent.; the other is antibacterial active metal nanomaterials. It is of great significance for preventing disease transmission, purifying environment, and protecting human health. In order to make full use of indoor sunlight and low light, new antibacterial ceramics have been actively developed.
Nano TiO2antibacterial coating has a long-lasting bactericidal effect, and it can also exert strong bactericidal effect under natural light, fluorescent lamp and even dark conditions.. Since the nano-TiO2is in the form of powder, it is generally required to uniformly disperse these powders into the resin during processing to obtain a desired antibacterial effect.
