并周边粘结密封，使玻璃层间构成单调气体空间的制品。中空玻璃的旷地空闲开始是单调的空气，现在多用导热率比空气低的其他气体，如惰性气体等。中空玻璃又称隔热玻璃,由两片或多片玻璃以有效支撑均匀离隔。
And the peripheral bonding seal makes the glass layer form a monotonic gas space product. The open space of the hollow glass was originally monotonous air, but now other gases, such as inert gases, with lower heat conductivity than air, are commonly used. Insulating glass, also known as insulating glass, is evenly separated by two or more pieces of glass.
抗风压成为幕墙的首要指标。中空玻璃的抗风压强度是单片玻璃的15倍玻璃不易自爆：中空玻璃出产方法为粘结法，抗风压强度前进：幕墙首要接受风荷载。为冷加工，玻璃原片内应力不改动，四周以弹性资料密封，玻璃不易自爆。
Wind resistance has become the primary indicator of curtain wall. The wind pressure strength of hollow glass is 15 times that of monolithic glass, which is not easy to spontaneous explosion. For cold working, the stress in the original glass sheet is unchanged, and the surrounding is sealed with elastic material. The glass is not easy to explode.
而镀膜中空玻璃的金属膜面处在单调的密封空气中永不坠落。镀膜玻璃膜层不会坠落：镀膜玻璃的金属膜面不可暂时露出于空气中。
The metal film surface of the coated hollow glass is kept in a monotonous sealed air and will never fall. The film of coated glass will not fall: the metal surface of coated glass shall not be temporarily exposed to the air.

中空玻璃具有隔音隔热保暖的作用而被广泛运用在家装中，可是市面上中空玻璃的质量良莠不齐，
Hollow glass has the function of sound insulation and heat preservation and is widely used in home decoration. However, the quality of hollow glass in the market is uneven.
1.看是否有铝隔条
1. see if there is aluminum partition.
铝隔条上还有许多透气孔，里面放上单调剂，可以吸收气体中的水分，避免玻璃门窗受热后出现“雾蒙蒙”的现象，而假“中空”玻璃没有这些设备。
There are also many air holes on the aluminum separator, which are filled with monotonic agent to absorb moisture in the gas, to avoid the phenomenon of "foggy" after heating the glass doors and windows, and the fake "hollow" glass does not have these equipment.
2.看外观
2. look at the appearance
优质的型材看上去外表润滑细腻、平整洁净、色彩均匀、没有裂缝、气泡;焊接处没有断裂开焊的现象;硬度厚度满足，用榔头敲击型材外表不出现分裂。而残次的型材色彩不均匀，有气泡杂质，用榔头敲击会出现分裂，甚至用手捏都会变形。消费者可以从旁边面查询玻璃，玻璃平整、没有色差，透过玻璃看物品，物品没有变形，就是合格的产品。
High-quality profiles appear to be lubricated exquisite, smooth and clean, uniform color, no cracks, bubbles; welded joints do not break open welding phenomenon; hardness and thickness meet, with hammers knocking profiles with no splitting. And the residual profile color is not uniform, there are bubble impurities, with hammer knock will split, and even with hand pinch will be deformed. Consumers can check the glass from the side, the glass is flat, no color difference, through the glass to see things, no deformation, is qualified products.
