中空玻璃是兩片或多片玻璃以有效支撐均勻隔開并周邊粘接密封，使玻璃層間形成有干燥氣體空間的制品。熱學性能：較低的 U 值（傳熱系數(shù)），充入惰性氣體效果更明顯；光學性能：根據(jù)實際需要十分靈活地選擇不同太陽光透過率和反射率；隔音性能：單腔體中空玻璃一般可降低噪音 30 分貝，通過增加腔室數(shù)量、PVB 夾膠等工藝還可進一步降低噪音值；防結露性能：露點可達 - 40℃確保中空玻璃不結露；密封性：采用雙道密封工藝，首道密封采用丁基膠或 45G 熱塑性間隔膠，二道密封采用硅酮膠或聚硫膠等，確保中空玻璃的密封性，延長中空玻璃的使用壽命。 The insulating glass is an article in which two or more pieces of glass are effectively supported to be evenly spaced and peripherally sealed to form a dry gas space between the glass layers.Thermal properties: lower U value (heat transfer coefficient), the effect of filling with inert gas is more obvious;Optical performance: According to actual needs, it is very flexible to choose different solar transmittance and reflectivitySound insulation performance: Single cavity insulated glass can generally reduce noise by 30 decibels, and the sound insulation performance of the glass can be further reduced by increasing the number of cavities, PVB lamination, and other processes;Anti-condensation performance: Dew point up to -40 ℃ to ensure that the insulating glass does not condense;Sealing: Adopting a dual sealing process, the first seal uses butyl rubber or 45G thermoplastic spacer adhesive, and the second seal uses silicone rubber or polysulfide adhesive to ensure the sealing performance of the insulated glass and extend its service life.
