空气净化瓦 一句话评价:除了阳光之外,不消耗任何能量。 如何应对日益严重的环境尤其是空气污染,可以说让人们费尽了心力与财力。而下面这项简单有效的创新或许提供了一些新的思路。 借助一系列创新的化学处理,常见的瓷砖瓦片就可以由普通的标准建材让沉默不语的建筑们一跃成为对抗空气污染的超级武器:碳化硼铝瓦片外层涂有的二氧化钛,能够与烟雾中的氮氧化物粒子发生反应,并将其中和。而最终产生的副产品亦是无害的,借助雨水便可冲洗干净。与其他防污手段相比,这种巧妙而简易的化学净气法绝对是最优秀的:它无需调用机械,不必安装设备,除了阳光之外,不消耗任何能量。 The 10 Most Innovative Tech Products of 2011 BoralPure Smog-Eating Tile Using some creative chemistry, Boral Roofing has turned a standard building material into a formidable weapon—not just against sun and rain, but also air pollution. The tile's coating contains TiO2 (titanium dioxide), which reacts with and neutralizes NO X (nitrogen oxide) particles in smog. The byproduct is a harmless precipitate that accumulates on the roof and washes away in the rain. That's pollution removal at its best. No machinery. No moving parts. No energy input other than sunlight. Just a clever, air-cleansing chemical reaction. (Price: approximately $650 more than a standard 2500-sq.-ft. tile roof) Read more: The 10 Most Innovative Tech Products of 2011 - Popular Mechanics 空气净化瓦
