Hollow glass in the course of Tai'an hollow glass wall, when the ambient temperature is lowered so that the glass surface temperature was lowered to the dew point within a layer of dry air when the surface layer of dry air will produce dew or frost. Due to condensation or frost glass surface and affect performance insulating glass. If the guarantee air layer at minus 40 degrees Celsius without condensation, hollow glass in the course of the air layer is not present condensation phenomena. Hollow glass is dew point rises into the air from outside of the water layer without being absorbed by the desiccant caused Taian hollow glass walls, there are three possible causes dew point rise: (1) sealant memory bubbles, causing the air moisture to enter. (2) diffusion of water vapor into the air through the polymer layer. Effective adsorption capacity (3) desiccant low. (1) strictly control the production ambient temperature mainly affects the production environment and the ability to attach the remaining adsorption capacity. (2) reduce the moisture diffusion through the polymer sealant mainly by selection of low permeability coefficient, determine a reasonable thickness of the seal, reducing the difference in temperature inside and outside of the hollow glass (meaning within a certain temperature range, a temperature range of production without giving too much) . 612a6 insulating glass insulating glass _ _ Shandong Yaohui preferred by Jinan Glass Co., Ltd.
