中空玻璃为什么一定要密封?

中空玻璃现在的普及度很大,下面全自动封胶机厂家就给大家简单介绍一下中空玻璃一定要密封的原因!
Hollow glass is now very popular, the following full-automatic sealant manufacturers will give you a brief introduction to the reasons why hollow glass must be sealed!
1、保护第一片玻璃的Low-E膜层,防止其氧化失去隔热的能力;
1. Protect the first glass Laow-E film to prevent its oxidation from losing its heat insulation ability.
2、最重要的是为了维持中空气层干燥——如果是湿润的空气,空气热阻低,保温效果差;干燥的空气热阻很高,有利于窗户保温。
2. The most important thing is to keep the middle air layer dry - if it is wet air, the air thermal resistance is low and the insulation effect is poor; the dry air thermal resistance is high, which is conducive to window insulation.
中空玻璃中间的铝隔条灌装的有分子筛(也就是中空玻璃加工用的干燥剂),可以吸附中空层空气中的水分子,保持其干燥。
Molecular sieves filled with aluminium partitions in the middle of hollow glass (i.e. desiccants for hollow glass processing) can absorb water molecules in the air of the hollow layer and keep it dry.

但分子筛的吸附能力是有极限的,如不密封,相当于分子筛一直在进行吸附,达到饱和也就失效了。
However, the adsorption capacity of molecular sieves is limited. If it is not sealed, it is equivalent to that molecular sieves have been adsorbing, which will fail to reach saturation.
当分子筛失效,中空层水汽含量就会逐渐升高…气温高的时候还好,一旦到了寒冷的冬天,玻璃中间就会起雾结露,而你只能眼睁睁的看着束手无策。不过等气温上去了,结露会自己消失的。
When the zeolite fails, the water vapor content in the hollow layer will gradually increase. It's good when the temperature is high. Once it's cold in winter, fog and dew will appear in the middle of the glass, and you can only watch helplessly. But when the temperature goes up, the dew will disappear by itself.
