中空玻璃它是用两片（或三片）玻璃，使用高度度高气密性复合粘结剂，将玻璃片与内含干燥剂的铝合金框架粘结，制成的效率高能隔音隔热玻璃。中空玻璃多种性能优越于普通双层玻璃，因此得到了世界各国的认可。
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，我国中空玻璃市场应用较多的为双道密封铝隔条式中空玻璃。而当问及众多中空玻璃加工的工作人员时，很多人难以准确的说出何为双道密封铝隔条式中空玻璃，以及其加工环境有什么要求。以下就由中华中玻网简要分析一下双道密封铝隔条式中空玻璃。
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.
双道密封铝隔条式中空玻璃，其靠前道密封（内层）采用丁基胶密封，丁基胶透气率较低，具有良好的密封性能。第二道密封（外层）一般采用聚硫胶密封，聚硫胶具有可控的固化速度，良好的粘结力，较低的水蒸气透过率、的结构强度和耐老化性能；隐框铝合金门窗用中空玻璃，第二道密封需采用硅酮结构密封胶密封。铝隔条有效支撑并均匀隔开两片玻璃，铝隔条内填分子筛干燥剂，使玻璃层间形成有干燥气体的密封空间。

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.
双道密封铝隔条式中空玻璃生产环境要求:
Environmental requirements for production of double-channel sealed aluminum spacer insulating glass:
（1）室内温度15℃～30℃；
(1) The indoor temperature is 15 ℃~30 ℃;
（2）室内相对湿度50%RH以下；
(2) The indoor relative humidity is below 50% RH;
（3）室内通风、干净、无尘。
(3) The room is ventilated, clean and dust-free.
密封胶使用前应按照国家有关标准，对其下垂度、粘度、挤出性、相容性、表干时间、固化时间等进行检验，合格后方可使用；生产前应先对密封胶、铝隔条、玻璃进行粘结性试验。
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.
