中空玻璃現在的普及度很大，下面全自動封膠機廠家就給大家簡單介紹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、保護片玻璃的Low-E膜層，防止其氧化失去隔熱的能力；
1. Protect the first glass Laow-E film to prevent its oxidation from losing its heat insulation ability.
2、重要的是為了維持中空氣層干燥——如果是濕潤的空氣，空氣熱阻低，保溫效果差；干燥的空氣熱阻很高，有利于窗戶保溫。
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.
中空玻璃中間的鋁隔條灌裝的有分子篩（也就是中空玻璃加工用的干燥劑），可以吸附中空層空氣中的水分子，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.

但分子篩的吸附能力是有極限的，如不密封，相當于分子篩一直在進行吸附，達到飽和也就失效了。
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.
當分子篩失效，中空層水汽含量就會逐漸升高…氣溫高的時候還好，一旦到了寒冷的冬天，玻璃中間就會起霧結露，而你只能眼睜睜的看著束手無策。不過等氣溫上去了，結露會自己消失的。
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.
