中空玻璃它是用兩片（或三片）玻璃，使用高度度高氣密性復合粘結劑，將玻璃片與內含干燥劑的鋁合金框架粘結，制成的效率高能隔音隔熱玻璃。中空玻璃多種性能優越于普通雙層玻璃，因此得到了世界各國的認可。
Insulating glass is an efficient and high-energy soundproof and heat-insulating glass made of two (or three) pieces of glass, which are bonded with the aluminum alloy frame containing desiccant by using a high degree of air-tightness composite adhesive. The insulating glass has many advantages over ordinary double-layer glass, so it has been recognized by all countries in the world.
目前，我國中空玻璃市場應用較多的為雙道密封鋁隔條式中空玻璃。而當問及眾多中空玻璃加工的工作人員時，很多人難以準確的說出何為雙道密封鋁隔條式中空玻璃，以及其加工環境有什么要求。以下就由中華中玻網簡要分析一下雙道密封鋁隔條式中空玻璃。
At present, the insulating glass market in China is mainly applied to double-channel sealed aluminum partition type insulating glass. When asked about many insulating glass processing staff, it is difficult for many people to accurately tell what is the double-channel sealed aluminum spacer type insulating glass and what requirements are for its processing environment. The following is a brief analysis of double-channel sealed aluminum spacer type insulating glass by China Glass Network.
雙道密封鋁隔條式中空玻璃，其靠前道密封（內層）采用丁基膠密封，丁基膠透氣率較低，具有良好的密封性能。第二道密封（外層）一般采用聚硫膠密封，聚硫膠具有可控的固化速度，良好的粘結力，較低的水蒸氣透過率、的結構強度和耐老化性能；隱框鋁合金門窗用中空玻璃，第二道密封需采用硅酮結構密封膠密封。鋁隔條有效支撐并均勻隔開兩片玻璃，鋁隔條內填分子篩干燥劑，使玻璃層間形成有干燥氣體的密封空間。

The double-channel sealed aluminum spacer type insulating glass, whose front seal (inner layer) is sealed with butyl rubber, has low permeability and good sealing performance. The second seal (outer layer) is generally sealed with polysulfide adhesive, which has controllable curing speed, good adhesion, low water vapor permeability, structural strength and aging resistance; Insulated glass shall be used for concealed frame aluminum alloy doors and windows. The second seal shall be sealed with silicone structural sealant. The aluminum spacer strip effectively supports and evenly separates two pieces of glass, and the aluminum spacer strip is filled with molecular sieve desiccant to form a sealing space with dry gas between the glass layers.
雙道密封鋁隔條式中空玻璃生產環境要求:
Environmental requirements for production of double-channel sealed aluminum spacer insulating glass:
（1）室內溫度15℃～30℃；
(1) The indoor temperature is 15 ℃~30 ℃;
（2）室內相對濕度50%RH以下；
(2) The indoor relative humidity is below 50% RH;
（3）室內通風、干凈、無塵。
(3) The room is ventilated, clean and dust-free.
密封膠使用前應按照國家有關標準，對其下垂度、粘度、擠出性、相容性、表干時間、固化時間等進行檢驗，合格后方可使用；生產前應先對密封膠、鋁隔條、玻璃進行粘結性試驗。
Before use, the sealant shall be inspected for sag, viscosity, extrudability, compatibility, surface drying time, curing time, etc. according to relevant national standards, and can only be used after passing the inspection; Before production, the adhesive test shall be carried out on sealant, aluminum spacer strip and glass.
