影响中空玻璃使用性能的因素有哪些

浏览:0
无论是单腔中空玻璃还是双腔中空玻璃,可以采用白玻组成中空玻璃,也可采用热反射镀膜玻璃组成中空玻璃,还可采用Low-E镀膜玻璃组成中空玻璃,中空玻璃的性能与所采用的玻璃直接相关。
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、密封胶、气体种类相同的情况下,气体间隔层越厚,间隔层热阻越大。其原因是气体间隔层越厚,气体分子传导传热的距离越大,使传热变得困难,相当于增大了气体间隔层热阻。但气体间隔层的厚度达到一定程度后,增加气体间隔层的厚度,热阻不再增加或有减小的趋势。

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.
一般情况下,中空玻璃的导热系数比单片玻璃低一半左右,其原因在于中空玻璃内干燥的空气间隔层的隔热作用。从而提高中空玻璃的隔热性能。考虑到氩气在空气中含量丰富,提取比较容易,使用成本低,所以为大多数工厂使用。需要说明的是,充入惰性气体,在中空玻璃厚度不变的情况下,提高隔热系数的同时,遮阳系数和可见光透过率不变。
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.
