The direct reason that affects the effective service time of insulating glass is the convergence speed of water in the middle layer. There are many factors that affect the convergence speed of water in the interlayer, such as material performance, manufacturing process and control, installation method, environmental aging, etc.

水的含量越高，空气的露点温度也就越高。当玻璃内表面温度低于空气层内空气的露点时，中空腔空气中的水气就会在中空玻璃中空腔内聚集，导致露点上升。当环境温度降低，玻璃内表面的温度低于空气层露点时，空气层内的水气便在玻璃内表面产生结露或结霜(玻璃内表面温度高于0℃时结露，低于0℃结霜)。由于玻璃内表面的结露或结霜，将会严重影响中空玻璃的透视度，并降低中空玻璃的隔热效果，同时长时间的结露会使玻璃的内表面发生霉变或返碱产生白斑，严重影响中空玻璃的使用。标准GBT 11944-2012《中空玻璃》规定露点温度为<-40℃中空玻璃露点上升，主要是由于外界的水分进入空气层而又不能被干燥剂吸收所造成的。

The higher the water content, the higher the dew point temperature of the air. When the temperature of the inner surface of the glass is lower than the dew point of the air in the air layer, the moisture in the air in the middle cavity will gather in the cavity of the insulating glass, causing the dew point to rise. When the ambient temperature decreases and the temperature of the inner surface of the glass is lower than the dew point of the air layer, the moisture in the air layer will produce condensation or frost on the inner surface of the glass (when the temperature of the inner surface of the glass is higher than 0 ℃, it will be dewed and frosted below 0 ℃). Due to the condensation or frost on the inner surface of the glass, the perspective of the insulating glass will be seriously affected, and the thermal insulation effect of the insulating glass will be reduced. At the same time, the long-term condensation will cause mildew or re alkali on the inner surface of the glass, which will seriously affect the use of the insulating glass. The national standard GBT 11944-2012 Insulating Glass stipulates that the dew point temperature of insulating glass is<- 40 ℃, and the dew point rise is mainly caused by the external moisture entering the air layer and cannot be absorbed by the desiccant.

提高中空玻璃使用寿命，延长有效使用时间使之达到标准要求，应从材料选择、加工制造、结构设计和安装等各个环节加以控制。

To improve the service life of insulating glass and extend the effective service time so that it can meet the standard requirements, it should be controlled from various aspects such as material selection, processing and manufacturing, structural design and installation.

加工制造这一环节，选择高质量的加工设备尤为重要，好的设备做好的产品。阅航全自动中空玻璃封胶线打胶密封性好，打胶漂亮饱满，可以延长中空玻璃使用寿命
