Hollow glass is dew point rises into the air from outside of the water layer without being absorbed by the desiccant resulting hollow glass top, 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 sealed insulating glass wall thickness, reducing the difference in temperature inside and outside of the hollow glass (meaning within a certain temperature range, temperature range production pation too big). Heating the glass should adopt multiple sets of roll 5mm hollow glass, gradually pressed to the desired thickness. Each group should roll parallel to each other, to ensure a uniform thickness of pressed glass. 2 by the press at the exit strip temperature should be controlled at 40-55 ℃. 3 composite tape insulating glass sealing three-step program that is pressed, abductions, pinch sealing operation completes final hollow glass. ① pressure: the outer edge of the strip along the vertical direction to squeeze another period of layering, the two strips until completely fused together; Weifang hollow glass, Yaohui glass, hollow glass window from Jinan Yaohui Glass Co., Ltd. provided.
