Background technique

Usually, most of the vacuum glass used in buildings and various equipment and facilities is made by supporting and isolating two layers of ordinary flat glass, and then sintering, vacuuming, sealing and other methods. Because the space between the two layers of flat glass is evacuated, this kind of vacuum glass has good heat insulation and sound insulation performance, and is widely used.

With the rapid construction of modern cities, high-rise buildings, especially super high-rise buildings, have developed rapidly like never before. In order to obtain good sound insulation, heat insulation and radiation protection effects, more and more vacuum glass is installed on these buildings.

When installing glass in high-rise buildings, stricter requirements are put forward for the safety of glass. Because ordinary glass is easily broken when it is accidentally hit. When the glass on the building is broken, it is often accompanied by larger glass fragments falling, and the sharp glass fragments pose a great threat to pedestrians or vehicles on the ground. In high-rise buildings, even super high-rise buildings, due to the high wind force, glass breakage is more likely to occur, and its threat is even greater. The solution to this problem in the past was to use very thick glass for windows and glass curtain walls. This method only reduces the probability of glass breaking, but does not fundamentally solve the threat problem caused by glass breaking.

When thick and heavy glass is used in buildings, the use of vacuum glass with multiple excellent performances such as high heat insulation and high sound insulation can only be abandoned.

For some laboratory equipment and special production equipment, due to the special requirements of scientific experiments and product production processes, some parts of these experimental equipment and production equipment must use vacuum glass, and when thick ordinary glass cannot be used, it provides safety. Higher vacuum glass is particularly important.

According to the above, providing vacuum glass that is not easy to break, will not cause harm to people after being broken, and has excellent sound insulation, heat insulation and strong light radiation resistance has become an urgent need for the glass manufacturing industry and even the glass use industry. question.

Detailed ways

Hereinafter, the utility model will be further described in detail through specific embodiments and in conjunction with the accompanying drawings.

Embodiment one

The structure of this embodiment is shown in Figure 1. It includes first tempered glass 1 , second tempered glass 2 , and ordinary flat glass 3 . Supports 4 are evenly distributed on the surface of the first tempered glass 1 . The ordinary flat glass 3 is arranged on the support 4 to form an isolation space 5 with the first tempered glass 1 . The peripheries of the two layers of glass are tightly sealed by the solidified body 6 formed by the low glass powder after thermal melting and cooling. In addition, a groove 35 for placing the getter 8 is also provided on the inner surface of the ordinary flat glass 3 in advance. During manufacture, first place low glass powder along the periphery of the first tempered glass 1, preheat to make the low glass powder melt slightly, and then set supports 4 evenly on the surface of the first tempered glass 1, and place ordinary flat glass 3 is placed on the support 4 while the getter 8 is placed in the groove 35. Usually, since the low glass powder is slightly higher than the support 4, the low glass powder melts during the subsequent low-temperature heating, so that the ordinary flat glass 3 falls on the support 4, and at the same time, the molten low glass powder forms after cooling. The solidified body 6 seals the peripheries of the two layers of glass, making the isolated space 5 a closed space.

In the present embodiment, the surface of the common flat glass 3 is provided with an exhaust seal for vacuuming, and the exhaust seal consists of a straight hole 31 provided on the surface of the common flat glass 3, a depression 32 provided on the outer surface of the glass at the periphery of the straight hole 31, The sealing sheet 33 and the solidified layer 34 formed by the low glass powder through heat melting and cooling.
