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.
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.
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.
In the process of manufacturing, it is particularly important to select high-quality processing equipment. Good equipment is good for good products.
