中空玻璃和真空玻璃的区别:
发布时间： 2023-10-19
真空玻璃和中空玻璃有什么区别性能差别很大，中空玻璃叫 “中空” 其实不是空的，两层玻璃中间有 “气体”，大多数情况下 “气体” 是空气，质量更好的是氩气，因为肉眼看不到气体，所以说它是 “空的。真空玻璃是在两层玻璃之间画一个“ 真空 ”。基本上，可以说没有气，真的是空的，为什么热水瓶可以长时间保持温暖？因为内胆内外壁之间是真空层，有效的阻隔了热量的传导，真空玻璃是将两块平板玻璃封住四周，中间留有缝隙，吸尘间隙，封住通风口。两块玻璃的内表面涂有一层或两层透明的低辐射薄膜。保温瓶由空腔内外两层玻璃外壳组成，空腔被吸尘，真空玻璃相当于把保温瓶做成平板，有人开玩笑说，真空玻璃窗实际上是“ 把保温瓶做在窗户上 ”。
If the thermos bottle at home leaks, it will not be insulated, which can reflect the difference in insulation performance between gas and no gas. Data show that the insulation performance of vacuum glass is 2 to 3 times better than that of insulating glass, more than 6 times better than that of ordinary monolithic glass, and much better than that of ordinary walls. Another feature of vacuum glass is that it is much thinner than hollow glass, which can save installation space and window frame materials. At the same time, due to its good heat preservation performance, its anti-condensation and fog performance is also very good, which can avoid the annoying things such as invisible exterior and dew soaking window sill caused by condensation and fog on the window. In winter, it can reduce the feeling of chilly in front of the window and the feeling of "surface wind" under the feet.
In addition to good thermal insulation performance, vacuum glass sound insulation performance is also better than hollow glass. The wind pressure strength of vacuum glass is about twice that of insulating glass made of the same glass, but the impact strength is not as good as that of insulating glass. This weakness can be solved by combining vacuum glass. For example, in the required location, laminated glass technology can be used to add tempered glass on one or both sides of the vacuum glass to form a safety vacuum glass with high impact strength and wind pressure resistance. Undoubtedly, the cost will increase accordingly.
In recent years, the most widely used new buildings in China are hollow glass. Insulating glass is also known as the "today's glass" title of the rich sense of the times. Vacuum glass than insulating glass started late, no matter from the industrialization of technology maturity and scale, vacuum glass is still in the early stage. However, due to its strong comprehensive performance advantages over insulating glass, its development prospects are very bright. With the expansion of production scale and technological progress, prices will also drop significantly. A few years later, vacuum glass is likely to replace insulating glass to become the mainstream product of energy-saving glass, which can be said to be "tomorrow's glass".
