Thin a thin glass, can hold back chill outside the door in the winter however, lie between burning hot block in in summer outdoor. "Use this kind of glass, above of energy-saving now half should be compared at least between our air conditioning. " Han Gaorong of professor of college of director of metalloid material institute, Zhejiang tells Zhejiang university inorganic the reporter.
This kind of magical glass, appearance is without peculiar place it seems that, the reporter is played with the hand play glass, give out the should become voice of common glass. The layer after Han Jiao awards those who pointing to glass says, the answer is here. Another besmear of original glass has a film. According to diverse functional demand, besmear with different plated film, this also produced two kinds big of magical glass: One kind is glass of sunshine control plated film, another kind is glass of low radiation plated film.
Sunshine controls plated film glass, plated film layer is given priority to with silicon or metallic titanium. This kind of magical glass has very good reflection effect, have to visible light absorb ability certainly. This character makes this kind of glass arose to hold back the competence with broiling summer magically. Use on this kind of glass, indoor air conditioning at least energy-saving 50% above, and the act wall glass of the world trade building of Hangzhou also is used already went up this kind of glass.
In the season that this day freezes coldly now, more the glass of plated film of low still radiation that yields a person to be interested. Many people have this kind of experience, opened the air conditioning of one night, charge of electricity many, still feel cold in the room. Scientist introduction, the reason depends on a building the specific power consumption of 1/3 above was dropped by door pane be lost. The mystical place of glass of low radiation plated film, depend on the coating that surface layer of this kind of glass besmeared with 2 oxidation stannum is given priority to, this kind of coating can be adiabatic, human body launchs the certain wavelengh that come out, namely quantity of heat also won't send out go out.
And more let a person cry absolutely is, mix heat insolation prevent cold plated film to adopt certain technique one case the glass on besmear, the thoroughly remould oneself on common glass horse, in summer can heatproof, can fight in the winter cold, became genuine " clever glass " .
According to introducing, the building of 90% above uses the Euramerican country with colder weather this kind of magical glass. Professor Han Gaorong says, ceng Yi of abroad of this kind of technology spends forestall, for this, our country begins own research and development, zhejiang goes in front row. Current, the edifice of the Christian era near Hangzhou yellow dragon, the floor area of nearly 10 thousand square metre will be used on " clever glass " .
"Clever glass " be about to throw production, but because the price is high, present price is 300 yuan / square metre, near 10 times more expensive than common glass. Professor Han Gaorong says, hangzhou city is used generally, after wanting to wait 35 years.
