影響中空玻璃使用性能的因素有哪些
無(wú)論是單腔中空玻璃還是雙腔中空玻璃，可以采用白玻組成中空玻璃，也可采用熱反射鍍膜玻璃組成中空玻璃，還可采用Low-E鍍膜玻璃組成中空玻璃，中空玻璃的性能與所采用的玻璃直接相關(guān)。
Both single cavity and double cavity hollow glass can make hollow glass with white glass. It can also use heat reflective coating glass to make hollow glass. It can also use Low-E coated glass to make hollow glass. The performance of the hollow glass is directly related to the glass used.
所用玻璃、密封膠、氣體種類(lèi)相同的情況下，氣體間隔層越厚，間隔層熱阻越大。其原因是氣體間隔層越厚，氣體分子傳導(dǎo)傳熱的距離越大，使傳熱變得困難，相當(dāng)于增大了氣體間隔層熱阻。但氣體間隔層的厚度達(dá)到一定程度后，增加氣體間隔層的厚度，熱阻不再增加或有減小的趨勢(shì)。
When the glass, sealant and gas are the same, the thicker the gas interlayer, the greater the thermal resistance of the interlayer. The reason is that the thicker the gas interlayer is, the greater the distance between the gas molecules to conduct heat transfer, making the heat transfer difficult, which is equivalent to increasing the thermal resistance of the gas compartment. However, when the thickness of gas interlayer reaches a certain level, the thickness of gas interlayer will increase, and the thermal resistance will no longer increase or decrease.
一般情況下，中空玻璃的導(dǎo)熱系數(shù)比單片玻璃低一半左右，其原因在于中空玻璃內(nèi)干燥的空氣間隔層的隔熱作用。從而提高中空玻璃的隔熱性能。考慮到氬氣在空氣中含量豐富，提取比較容易，使用成本低，所以為大多數(shù)工廠使用。需要說(shuō)明的是，充入惰性氣體，在中空玻璃厚度不變的情況下，提高隔熱系數(shù)的同時(shí)，遮陽(yáng)系數(shù)和可見(jiàn)光透過(guò)率不變。
Under normal circumstances, the thermal conductivity of insulating glass is about half lower than that of monolithic glass, which is due to the insulation effect of dry air interlayer in insulating glass. Thus, the insulating property of the insulating glass is improved. Considering that argon is abundant in air, it is easy to extract and low in use cost, so it is used in most factories. It is necessary to explain that the inert gas is filled with the constant thickness of the insulating glass, and the coefficient of sun shading and the transmittance of visible light are constant while the heat insulation coefficient is increased.
