物体上的污垢,玻璃上的尘埃,空气中的有害物质……要除去这些东西非常麻烦,有什么办法能使这类工作变得轻松容易些呢?现在,一种称着“光催化”的技术可望解决这个难题。当光(主要是紫外光)照在一种叫“氧化肽”的薄膜上时,薄膜表面会出现化学反应,并产生一种叫“活性氧”的分子,这种分子有强烈的氧化作用,能分解附着在氧化肽上的有机物,致使其上的污垢分离瓦解和自动脱落,利用这个特性,将氧化肽涂在某物体的表面,这个表面就具有了抗虫尘、除菌、消臭的性能.光催化现已在日本广泛应用.它在日用品、汽车、建材、通讯、交通等领域大显身手,前景非常广阔。3年前,日本将公路隧道中的照明灯玻璃全部换上涂了氧化肽的新型玻璃。当玻璃上沾了污物时,只要用光一照,污垢就会分解脱落,玻璃又明亮如初了。生产空调和空气净化设备的厂家对光催化技术也大感兴趣,纷纷将其应用于产品制造中。他 Dirt on objects, dust on glass, and harmful substances in the air ... To remove these things is very troublesome, is there any way to make this kind of work easier and easier? Now, a call “photocatalytic ”The technology is expected to solve this problem. When light (mainly UV light) shines on a film called “oxidized peptide ”, the surface of the film is chemically reacted and produces a molecule called “reactive oxygen species” that has a strong Of the oxidation, can break down the organic matter attached to the oxidized peptide, resulting in the separation of the dirt on its collapse and automatic shedding, the use of this feature, the oxidation of peptide coating on the surface of an object, this surface has a insect-resistant dust, sterilization , Deodorizing performance.Catalyst has been widely used in Japan.It is in the daily necessities, automobiles, building materials, communications, transportation and other fields to show their talents, the prospects are very broad. Three years ago, Japan replaced all of the lighting glass in the highway tunnel with a new glass of oxidized peptide. When the glass stained with dirt, as long as a light, dirt will break down, the glass is bright again. Manufacturers of air-conditioning and air purification equipment are also interested in photocatalytic technology, have been used in product manufacturing. he
