研究人员正在开发一种轻质半透明凝胶状物质。这种具有独特冷热调节性能的材料可用于改变窗户和建筑物的隔热方式,节省燃料费用。气凝胶是30年代由美国科学家发现的。他们在高温高压下设法使硅胶脱水而又不发生结构破坏和收缩,制得了具有超级绝热性能的气凝胶板。业已发现:厚度只有15mm的气凝胶板的热散失量不到普通玻璃板的1/12。即使与由双层镀银玻璃板构成并充有
Researchers are developing a light translucent gel-like material. This unique cold conditioning material can be used to change the insulation of windows and buildings, saving fuel costs. Airgel was discovered by American scientists in the 1930s. They managed to dehydrate the silica under high temperature and pressure without structural damage and shrinkage, resulting in an airgel sheet with super-thermal insulation properties. It has been found that the heat loss of an airgel sheet having a thickness of only 15 mm is less than 1/12 of that of a normal glass sheet. Even with a double-silvered glass plate and filled
