PRODUCT光觸媒

  1. 通過光的照射,激發光觸媒半導體的強氧化還原特性,
    當有害氣體遇到光觸媒時,會被氧化分解,
    像樹葉一樣分解污染物,釋放負離子,改善空氣質量。

  1. 示意圖
  1. 光觸媒具有以下特性
  1. 光觸媒技術原理
  2. 納米光觸媒在光照射下,價帶電子被激發到導帶,形成了電子和空穴,
    與吸附于其表面的O2和H2O作用,生成超氧化物陰離子自由基,
    O2-和羥基自由基-OH,其自由基具有很強的氧化分解能力,
    能破壞有機物中的C-C鍵、C-H鍵、C-N鍵、C-O鍵、O-H鍵、N-H鍵,
    分解有機物為二氧化碳與水;同時破壞細菌的細胞膜固化病毒的蛋白質,
    改變細菌,病毒的生存環境從而殺死細菌、病毒。
  1. 光觸媒技術原理
  1. 空氣凈化
  2. 對甲醛、苯系物、揮發性有機物、氨氣、二氧化硫、一氧化碳、氮氧化物、汽車尾氣等影響人類身體健康的有毒物質,在光催化作用中,其中有機物分解為二氧化碳和水,從而凈化空氣。
  1. 負氧離子
  2. 釋放負氧離子,中科院理化技術研究所對光觸媒進行檢測后發現,使用優質光觸媒噴涂100平米建筑面積的房間,相當于種了25棵白樺樹的凈化效果。
  1. 抗菌防霉
  2. 對大腸桿菌、金色葡萄球菌、肺炎桿菌、霉菌等病菌具有殺滅功能的同時還能分解由病菌釋放出的有害物質。
    1. 除臭除味
    2. 生活環境的臭味大多是有機物,如油漆中的有機溶劑,餿水中的含氮有機物氣體,香煙味、廁所臭、動物臭等等,有機物都有碳基極易與納米光觸媒反應,從而分解為沒有污染的CO2和H2O。
    1. 除臭除味
    2. 物體表面的污垢大多是含油脂污染物。油脂也是有機物,基于光催化的機理所以能分解后剝離于物體表面。
    1. 凈化
    2. 具有水污染的凈化及水中有機有害物質的凈化功能,且表面具有超親水性,有防霧、易洗、易干的效能。
      1. 親水防霧
      2. 二氧化鈦光觸媒表面與水滴的接觸角幾乎是零度,所以表面覆有二氧化鈦光觸媒的物體都有親水防霧的功能。
      光觸媒作為新興的空氣凈化產品,越來越多的應用于室內和車內的空氣凈化。
