The difference and different applications of vacuum glass and hollow glass

2023-04-24


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.

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.Vacuum glass is to melt and seal two pieces of glass (one of which is white glass and the other is low-E glass) around each other. The two pieces of glass are separated by a very small support to prevent the two pieces of glass from being sucked together when vacuuming at high temperature to form a vacuum layer of 0.1~0.2mm. After venting, the exhaust port is melted and sealed.

The hollow glass is called "hollow" and is actually not empty. There is “qi” in the middle of the two layers of glass. In most cases, “qi” is air, and the better quality is argon. Since the gas cannot be seen with the naked eye, it is said to be “empty”.It is made of two (or three) pieces of glass, using a high-strength and high-airtight composite binder, the glass sheet is bonded to the aluminum alloy frame containing the desiccant, and the high-performance sound insulation glass is made.Its main materials are glass, aluminum spacers, angled bolts, butyl rubber, polysulfide rubber, and desiccant.

"Carbon neutrality” brings new changes to the supply side of the glass industry

In the high-energy-consuming industry, “carbon neutrality” is expected to bring about total supply control and an increase in the share of dominant companies.According to the calculation of 360 tons of carbon dioxide emitted per unit of 10,000 heavy boxes, China's carbon dioxide emissions from flat glass in 2020 will be about 34 million tons.
