Vacuum glass accelerates industrialization

It is reported that glass deep processing industry is facing good opportunities for development ------- Glass vacuum glass is a glass process and materials science, vacuum technology, physical measurement technology, industrial automation and construction science, a variety of disciplines, a variety of technologies, A variety of collaborative processes and cooperation.

Experts pointed out that vacuum glass should be combined with currently mature coated glass, laminated glass, filmed glass, insulating glass and other glass deep processing products, or different thickness glasses, different performance glass coatings, and different types of coated glass. The "Super Glass" has enabled a variety of new glass materials with higher physical properties to exhibit a variety of new functions to meet the new requirements of modern society and science and technology in the fields of doors and windows and a wider range of applications. For example, if an ordinary double glass or hollow glass is used in a severe cold area below 20°C, the phenomenon of frost formation is very serious. The use of low-emission vacuum glass has no such drawbacks and it has greater advantages. The modern transportation system uses elevated, overpass, rail trains and other forms. It is convenient and at the same time, it also brings noise. Shanghai's elevated roads are within easy reach of private houses and can only be blocked by curved plastic panels. If vacuum glass can be used in the future, it will significantly reduce noise. Another example is the refrigerated display cabinet glass door must be beautiful, perspective, but also in the high temperature and humidity environment is not frost, but also energy-saving, the current hollow glass products, large thickness and low thermal resistance, can not meet such a demanding requirements . We all took the train. The ordinary double-glazed windows of the train seemed to be thick and heavy. It was also a waste of transport and condensation. It was not commensurate with the speed of railway transportation several times; in addition, it was used on ships, cars and even aircraft. Window glass has been improved. Therefore, the large-scale industrialization of vacuum glass will be a good development opportunity for the glass deep processing industry.

Institute of Energy and Power Engineering and Institute of Electron Physics and Devices of Xi'an Jiaotong University have taken the initiative to study the use of flat vacuum glass as a solar collector cover. As a result, in the range of 500-700 W/m sunlight, vacuum glass covers The collector can reach 140~C, which is 15~2O°C higher than that of the ordinary double glass, and the temperature difference between the inner and outer surfaces of the vacuum glass cover can reach more than 30°C. Ordinary double glass is generally only 5~10°C. about. The solar collector vacuum glass cover requires much lower requirements than vacuum glass for doors and windows, and the structure and production technology can be simplified accordingly, facilitating large-scale application.
