中空玻璃的主要功能及影響要素
Main functions and influencing factors of insulating glass
中空玻璃多種功能優(yōu)越于一般雙層玻璃，因而得到了世界各國(guó)的認(rèn)可，中空玻璃是將兩片或多片玻璃以有效支撐均勻離隔并周邊粘結(jié)密封，使玻璃層間構(gòu)成有枯燥氣體空間的玻璃制品。
Hollow glass has many functions superior to ordinary double-layer glass, so it has been recognized by all countries in the world. Hollow glass is a kind of glass product that can effectively support two or more pieces of glass to separate evenly and seal the surrounding area, so that the glass layers can form a dull gas space.
1.氣體間隔層的厚度：主要是經(jīng)過(guò)對(duì)厚度的控制，使中空玻璃內(nèi)部構(gòu)成紊態(tài)氣流的傳熱，盡量控制氣體的冷熱氣體彼此攪擾或者說(shuō)使其上升與下降的氣流互相攪擾來(lái)控制產(chǎn)生對(duì)流傳熱。
1. Gas spacer thickness: mainly through the control of thickness, so that the interior of the hollow glass constitutes turbulent flow of heat transfer, as far as possible to control the cold and hot gases of the gas to disturb each other or to make the rising and falling air flow to disturb each other to control the generation of convective heat transfer.
2.空氣層間的氣體品種和濕度：在中空玻璃的內(nèi)部充入的惰性氣體，能夠下降中空玻璃的隔熱、隔音功能。如充入氬氣和氟化硫可分別進(jìn)步中空玻璃的隔熱、隔音功能。
2. Gas species and humidity between air layers: inert gas filled in the interior of hollow glass can reduce the heat and sound insulation function of hollow glass. If argon and sulfur fluoride are added, the insulation and sound insulation function of insulating glass can be improved. It

3.中空玻璃的邊部密封狀況：一方面，假如中空玻璃的邊部密封欠好，則水氣經(jīng)過(guò)密封膠層進(jìn)入中空玻璃內(nèi)部的份額應(yīng)以增大，中空玻璃壽數(shù)就會(huì)削減；另一方面，假如中空玻璃的邊部資料的導(dǎo)熱功能好，那么經(jīng)過(guò)中空玻璃的隔熱系數(shù)就會(huì)進(jìn)步，隔熱功能就會(huì)下降。
3. Sealing condition at the edge of hollow glass: on the one hand, if the edge of hollow glass is not well sealed, the share of water vapor passing through the sealant layer into the interior of hollow glass should be increased, and the lifetime of hollow glass will be reduced; on the other hand, if the thermal conductivity of the edge data of hollow glass is good, it will pass through the insulation of hollow glass. The thermal coefficient will improve and the insulation function will decrease.
4.玻璃的熱透率：中空玻璃的傳熱主要以輻射傳熱的方法進(jìn)行，假如采用高透過(guò)率低反射率的一般通明玻璃，則中空玻璃的隔熱功能，較采用高反射低透過(guò)的鍍膜或ＬＯＷ－Ｅ玻璃的低許多。
4. Thermal transmittance of glass: The heat transfer of hollow glass is mainly carried out by radiation heat transfer. If the general open glass with high transmittance and low reflectivity is adopted, the insulating function of hollow glass is much lower than that of coated glass with high reflection and low transmittance or LOW-E glass.
5.玻璃平面尺度：加大中空玻璃的平面尺度，能夠削減中空玻璃單位面積的熱量損失，進(jìn)步中空玻璃的全體隔熱作用。一起，在中空玻璃門窗的裝置過(guò)程中，假如玻璃扣條裝置欠好或密封不緊密，構(gòu)成整個(gè)窗或玻璃內(nèi)外透氣，產(chǎn)生對(duì)流，導(dǎo)致能量丟失，影響其功能。
5. Glass plane scale: Increasing the plane scale of hollow glass can reduce the heat loss per unit area of hollow glass and improve the overall insulation of hollow glass. Together, in the process of installing hollow glass doors and windows, if the glass buckle device is not good or tightly sealed, it will make the whole window or the inside and outside of the glass permeable, generate convection, cause energy loss and affect its function.
