[China Glass Net] The dew point of the insulating glass refers to the temperature at which the humidity of the air sealed in the air layer reaches a saturated state. Below this temperature, the water vapor in the air layer condenses into liquid water. It can be introduced that the higher the water content, the higher the dew point temperature of the air. When the inner surface temperature of the glass is lower than the dew point of the air in the air layer, the moisture in the air will condense or frost on the inner surface of the glass. The dew point rise of the insulating glass is caused by the external moisture entering the air layer without being absorbed by the desiccant. There are three reasons that may cause the dew point to rise: 1. There are air bubbles in the sealant, which causes air moisture to enter. 2. Water vapor diffuses into the air layer through the polymer. 3. The effective adsorption capacity of the desiccant is low. Insulating glass dew point control measures: 1. Strictly control the production environment temperature, the production environment mainly affects the ability and residual adsorption capacity. 2. Reduce the diffusion of moisture through the polymer: mainly choose the sealant with low permeability coefficient to determine the reasonable sealing thickness and reduce the temperature difference between the inside and outside of the insulating glass (that is, control the production within a certain temperature range without making the temperature range too large) . 3. Reduce the production process time: minimize the contact time of the desiccant with the atmosphere, reduce the loss of adsorption capacity and make the desiccant have higher adsorption capacity. 4. Choose a suitable aluminum profile: the pores of the pores should be small to reduce the water absorption of the molecular sieve during operation. 5. Choose a suitable desiccant: choose a desiccant with a high adsorption rate and a long lasting effect.
