Recently, some industry professionals pointed out that the energy consumption of real estate buildings is staggering. All the exterior walls of the house use glass curtain walls. Although they are beautiful, they are typical high-energy-consuming doors and windows.In this regard, relevant people believe that it is necessary to promote energy-saving building materials.

The coated glass can reflect visible light (heat reflection/sunlight control film) and far infrared rays (low-E low-radiation film) through the reflection function of the film layer to achieve partial heat energy control through the glass; hollow glass is double-layer or multi-layer glass and forms an intermediate cavity, using the poor thermal conductivity of the air can effectively control the heat conduction (convection heat transfer, conduction heat transfer and radiation heat transfer) in the conduction heat transfer, so as to achieve energy saving.

According to relevant reports, the scale of the architectural glass market will grow at a compound annual growth rate of 7.3% from 2020 to 2025, reaching US美元163.56 billion by 2025.

Due to production, installation and construction reasons, coated glass often loses film, spots or pinholes, scratches or abrasions, cracks and other phenomena during use. The causes of these phenomena are multifaceted, whether it is sunlight control film or low-radiation coating, only by finding the cause of its formation can the occurrence of similar situations be effectively reduced.

Vacuum glass is a kind of deep-processed high-performance glass, which is developed based on the principle of thermos flask.The structure of vacuum glass is similar to that of hollow glass, except that the gas in the cavity of vacuum glass is very thin and almost close to vacuum.
