最近,在医院里由于感染等造成的细菌的环境污染已作为社会问题提了出来.以此为背景,考虑若建材自身具有能抑制细菌繁殖的功能,则有望保持环境的清洁,可减少清洁维修费用.从这一点考虑,日本东陶机械株式会社在世界率先开发出用氧化钛光触媒的抗菌陶瓷面砖.下面简要介绍氧化钛光触媒技术和抗菌面砖.氧化钛光触媒的作用原理氧化钛具有光触媒作用,用入射的光作为能源,使空气中的氧和水分变成活性氧.这种活性氧具有能分解各种有机物、无机物的功能.接触细菌时,能靠光触媒的分解作用使细胞膜破坏,可在短时间内杀掉细菌.这类光触媒,不仅对细菌,而且对一般的污染的防止也能发挥很好的效果.是能抗菌、防止污染、防臭等多功能的新型材料.象植物的叶绿素,使用氧化钛制出的活性氧.这样的光触媒作用是1972年由东京大学工学院藤岛昭教授发现的.氧化钛光触媒技术的开发菌陶瓷面砖.下面简要介绍氧化钛光触媒技术和抗菌面砖.氧化钛光触媒的作用原理氧化钛具有光触媒作用,用入射的光作为能源,使空气中的氧和水分变成活性氧.这种活性氧具有能分解各种有机物、无机物的功能.接触细菌时,能靠光触媒的分解作用使细胞膜破坏,可在短时间内杀掉细菌.这类光触媒,不仅对细菌,而且对一般的污染的防止也能发挥很好的效果.是能抗菌 Recently, bacterial environmental pollution caused by infections in hospitals has been raised as a social issue. Considering this as a background, if building materials themselves have the function of inhibiting bacterial growth, they are expected to keep the environment clean and reduce the need for cleaning and maintenance. Cost. From this point of view, Japan Toto Machinery Co., Ltd. has taken the lead in the world to develop antibacterial ceramic tiles using titanium oxide photocatalysts. The following briefly describes titanium oxide photocatalyst technology and antibacterial tiles. The role of titanium oxide photocatalysts Titanium dioxide has a photocatalytic effect. By using incident light as an energy source, oxygen and moisture in the air become reactive oxygen species. This reactive oxygen species has the function of decomposing various organic and inorganic substances. When exposed to bacteria, the cell membrane can be destroyed by decomposition of the photocatalyst. Kill bacteria in a short time. Photocatalysts of this type not only have a good effect on bacteria, but also prevent general pollution. It is a new type of material that can resist bacteria, prevent pollution, and deodorize. It is like a plant’s chlorophyll. Using reactive oxygen species made from titanium oxide. This photocatalytic effect was discovered in 1972 by Prof. Fujishima Chiaki of the Faculty of Engineering at the University of Tokyo. Titanium photocatalyst technology development bacteria ceramic tile. Here is a brief introduction of titanium oxide photocatalyst technology and antibacterial tile. Titanium dioxide photocatalyst principle of action Titanium dioxide has a photocatalytic role, using the incident light as energy, so that the air of oxygen and moisture become active Oxygen. This reactive oxygen species has the function of decomposing various organic and inorganic substances. When exposed to bacteria, it can destroy the cell membrane by the decomposition of photocatalyst and kill bacteria in a short time. Such photocatalysts are not only bacteria, but also Prevention of general pollution can also exert very good results. It is able to be antibacterial
