Microwave-welded flat tempered vacuum glass edge-sealed with sealing groove and having getter

Abstract

A microwave-welded flat tempered vacuum glass edge-sealed with sealing grooves and having a getter is characterized in that an upper glass and a lower glass are flat tempered glasses. A vacuumizing hole is arranged in the upper glass and a sealing cover is arranged on the vacuumizing hole. The getter is arranged in the vacuumizing hole. The upper glass is provided with a sealing bar and the lower glass is provided with the sealing groove. The upper glass and the lower glass are welded to each other in a microwave oven at a normal pressure through a low-temperature glass solder. The vacuumizing hole is automatically sealed in a vacuum oven through the seal cover and a metal solder. The getter is automatically activated during the sealing process. A vacuum layer, with a supporting object therein, is formed between the upper glass and the lower glass. The edge-sealing bar and the supporting object are composed of tempered glass printing ink and a high polymer. The high polymer is firstly prepared into a pre-polymer. The pre-polymer, after the glass being tempered, is manufactured on the glass or the tempered glass printing ink. The pre-polymer is solidified to form an elastomer at room temperature or a high temperature. The pre-polymer or the elastomer can automatically adapt with change of height of the vacuum layer. Volatile gas in the elastomer is exhausted from the elastomer at a high temperature and a high vacuum degree.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat tempered vacuum glass with a getter on the edge of a microwave welding sealing groove and a manufacturing method thereof. Background technique [0002] Vacuum glass is a new type of energy-saving glass. Vacuum glass can not only solve the "breathing" problem of insulating glass used in large quantities, but also has good heat and sound insulation performance, high wind pressure resistance, small thickness and long service life. advantage. Vacuum glass is generally composed of two to three pieces of glass, a cavity is formed between two adjacent pieces of glass, and an edge sealing structure is arranged around the glass, and the cavity is evacuated to form a vacuum layer. Vacuum glass can be divided into two types according to the way of forming the vacuum layer. One is the vacuum glass without exhaust port. The edge sealing of this vacuum glass is carried ou...

AI Technical Summary

Problems solved by technology

Due to the small space in the vacuum layer of vacuum glass and the transparency of the glass, the protection and activation of the getter needs to be considered, so it is very difficult to place the getter in the vacuum layer

The traditional method of placing the getter in the vacuum glass is to first package the getter under vacuum, and then place it in the groove pre-opened on the glass. After sealing the edge of the vacuum glass, vacuuming, and sealing the suction port , and then use laser or infrared rays to open the package of the getter to activate the getter. The disadvantage of this method is that the encapsulation and placement process of the getter is complicated, the amount of the getter is small, and the appearance and mechanical properties of the glass are affected.
