Because there may be an internal insulating glass desiccant adsorbed water molecules, the gas is dry, when the temperature is lowered, the interior of the hollow glass condensation phenomenon does not occur at the same time, the outer surface of the hollow glass dewpoint will rise high. For example, when the outdoor wind speed of 5m / s steel hollow glass, indoor temperature 20 ℃, relative humidity of 60%, 5mm glass at the outdoor temperature is 8 ℃ at the beginning of condensation steel hollow glass Which is good, and 16mm (5 + 6 + 5) insulating glass under the same conditions, when the outdoor temperature is -2 ℃ on condensation, 27mm (5 + 6 + 5 + 6 + 5) three hollow glass when the outdoor temperature is -11 ℃ start condensation. Convective transfer is due to the temperature difference between both sides of the glass with a steel hollow glass manufacturers, resulting in cold air on one side of the drop and the heat rises Buying steel hollow glass, resulting in air convection, resulting in the loss of energy. The reasons for this phenomenon are a few: First, seal the glass and the surrounding frame system is bad, causing the gas inside and outside of the window frame can be exchanged directly convection, resulting in the loss of energy; Buying steel hollow glass, Qingdao steel hollow glass, Jinan Yaohui preferred by Yaohui Glass Co., Ltd., Jinan. Jinan Yaohui Glass Co. (www.jyhhc.com/) strong, credible, in Jinan, Shandong architectural glass industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jinan Yaohui glass and you hand into the brilliant, for a better future!
