With the constant improvement of residential taste, people's demand for decoration is also increasing. How many do you know that vacuum glass has become a pet of home decoration?
Vacuum glass is a new type of glass deep-processing products. It consists of two pieces of glass, one is white glass, the other is low-emissivity film glass. It is exhausted at high temperature to vacuum, sealed with glass powder, and separated by support, forming glass with a certain thickness of sandwich. The heat loss by conduction, convection and radiation of vacuum glass is lowest, and its working principle is the same as that of glass thermos bottle.
Vacuum glass has the following advantages:
1. Insulation and insulation. To eliminate the influence of thermal radiation and cold radiation near the left of doors and windows, and to adhere to the warm home environment of warm winter and cool summer.
2. Keep away from condensation. Super heat preservation and insulation performance, no air in the vacuum layer of vacuum glass, more water vapor molecules. In cold winter, the outward temperature of indoor glass is similar to that of room temperature. It is not easy for indoor glass to fog due to temperature difference.
3. energy saving. Vacuum glass doors and windows depend on the special structure of vacuum layer, which can effectively prevent heat conduction. Its heat transfer coefficient makes the energy saving of hollow glass doors and windows more than double. According to the relevant experiments, the heat transfer coefficient U is below 0.6Wm-2k-1, and can be as low as 0.3W/(m.K), which is similar to the wall.
4. mute. Noise directly affects physical and mental health. However, with the development of urban economy, high-quality buildings are often located in busy sections, such as schools, activity centers, traffic arteries, etc. The vacuum layer of vacuum glass can effectively block the transmission of sound, especially the medium and low frequencies with strong penetration, and the effect is remarkable.
Defects of vacuum glass: Wind pressure is the common advantage of vacuum glass, but impact strength is far inferior to that of hollow glass. In addition, the consumption process of vacuum glass is more complex and more expensive raw materials, which makes its market price relatively expensive.
