Introduction:
When we complete in the new decoration perhaps the family increases the new furniture, the air is always sending out the formaldehyde; The formaldehyde serves as the natural lumber the antiseptic treatment, continues to use continuously spreads all the various trades and occupations until now, but in people widespread formaldehyde time, actually neglects its important nature, that is the formaldehyde is virose, the long time contact formaldehyde, can cause many kinds of cancers the occurrence.
Decomposition organic matter principle:
As soon as the new compound materials pass through the illumination, in raw material titanium dioxide electronic (e-) then meet the ad valorem electron belt (valence band) to jump to pass on the conduction band (conduction band) and are separated from, therefore the light catalyst surface produces electronic (e-) and the electricity hole (h+), the electronic electricity hole meets and in the environment H2O carries on the response, then produces the belt cathode hydrogen free radical (‧ H) with the belt positive electrode oxyhydrogen free radical (‧ OH), these free radicals may aim at in the environment decomposition the deleterious substance.
When the organic matter (hydrocarbon) contacts the light catalyst surface, then can with the hydrogen free radical and the oxyhydrogen free radical union.The free radical can rob the electron from other organic matters, but robs electronic the organic matter to be able because loses the key to tie ability (valence) to degrade into a smaller member, carbon dioxide, water.This a succession of response, on academic is called 'redox reaction' (Redox reaction).
Using:
After decoration & new furniture & paint… and so on.
