Vacuum glass is a new type of glass deep processing product, which is developed and produced based on the principle of thermos bottle. The structure of vacuum glass is similar to that of insulating glass. The difference is that the gas in the vacuum glass cavity is very thin and almost close to vacuum. Technically, our vacuum glass is separated by a 0.2mm-0.4mm high support, and the edges of the two layers of glass plates are sealed with low-temperature glass, and then the air is discharged. The vacuum degree between the glasses is 10-4Pa, so the thermal convection no longer exists, the heat conduction is reduced to the limit, and the Low-E layer reflects more than 95% of the infrared radiation. Therefore, the heat between the inner and outer glass plates cannot be exchanged, achieving excellent thermal insulation effect. Its working principle is the same as that of glass thermos. Vacuum glass is the fruit of the cooperation of glass technology and material science, vacuum technology, physical measurement technology, industrial automation and construction science, as well as a variety of disciplines, technologies and processes.

Firstly, the market development environment and the overall operation situation of vacuum glass industry are introduced, then the current situation of market operation of vacuum glass industry is analyzed, and then the competition pattern of vacuum glass market is introduced. Then, the report analyzes the operation status of key enterprises of vacuum glass, and finally analyzes the development trend and investment forecast of vacuum glass industry.
According to several German experts, the contradiction between the desire to further reduce the U value and the thick and heavy glass has become a difficult problem for many experts and real estate developers. Many people are thinking about how to change in the next step. Compared with insulating glass, vacuum glass has the advantages of low U value and thin thickness. For example, with the aforementioned Low-E glass with emissivity of 0.03, it is not difficult to produce a single Low-E vacuum glass with U value of about 0.31w/m2•K and a double Low-E vacuum glass with U value of 0.25w/m2•K. not only is the thickness much thinner than the hollow glass, but also the Low-E membrane is in a vacuum environment, which can be fully protected from oxidation failure, which is an important reason for attracting scientists to study vacuum glass. As a leading company who has been dedicated to researching and developing vacuum glass products and energy saving building glass for many years, ICESUN Vacuum Glass company has released a series of vacuum glass products including vacuum insulated glass, tempered vacuum glas and vacuum composite glass for the windows and doors of buidlings, passive house and curtain walls.
Under the global trend of advocating energy conservation and environmental protection, vacuum glass has great development advantages and potential in the fields of building energy conservation, green household appliances and transportation with its unique advantages of super sound insulation, super heat insulation, anti condensation and long service life, and the market demand continues to grow. With the requirements and attention of domestic policies on low-carbon environmental protection, energy conservation and emission reduction, it is expected that China's annual output of vacuum glass will reach 2.5 million square meters by 2024, and the vacuum glass industry is facing huge development space.
