In the first embodiment shown in the fig. 2, the vacuum glass is formed by compounding the bottom glass plate 2 and the top glass plate 3, and the sealing edge 1 of the top and the bottom glass plates 2, 3 close to the edge is formed by the metallized layers 6 fixedly bonded at the surface of the glass plate and the metal sealing sheet 7 having a U-shaped cross-section, both side edges of the metal sealing sheet 7 and the metallized layers 6 on the top and the bottom glass plates are welded and connected in air-tight manner through metal braze welding process, the mounting hole 8 is made at the outer side of the sealing edge 1 , and the mounting hole 8 and the vacuum space 5 are isolated with each other by the sealing edge 1. The metallized layer 6 is fixedly bonded with the surface of the to-be-sealed part of the glass plate, the metallized layer 6 is formed on surface of the glass by sintering process, and the following sintering process for the metallized layer is:
Firstly preparing the metal paste coating on the to-be-sealed positions surface of the glass plate in dip coating, spray coating, silk screen printing, manual coating or mechanical coating manner;
Then heating the glass plate, and sintering the metal paste coating into the metallized layers fixedly bonded with the glass plate.
When the metallization paste coating is sintered, the sintering can be finished by heating the glass plate completely and also can be finished by locally heating the coating part, wherein the heating manner can be laser heating, flame heating, current heating, induction heating or microwave heating, and the like.
When the metal brazing solder is installed between the sides of the metal sealing sheet 7 and the metallized layers 6 on the glass plates 2, 3, the brazing solder can be processed into a metal foil and then the metal foil is arranged between the metal sealing sheet 7 and the metallized layers 6, and also the brazing solder is metallically pre-plated on the sides of the metal sheet, and/or pre-plated on the surface of the metallized layers 6, and then the subsequent welding is finished according to the metal brazing process.
When braze welding is done between metallized layers 6 and the metal sheet 7, preferably tin alloy solder is used as brazing solder, and the advantage is that a relatively low welding temperature (generally no more than 250 Celsius) can be used when welding, thereby being capable of preventing the braze welding temperature from influencing the performance of glass plate. The glass plate has been tempered or semi-tempered or heat strengthened before braze welding, thus the braze welding temperature is controlled to be no more than 350 Celsius so as to be capable of preventing the tempered glass plate from being annealed in braze welding process.
The braze welding process can carried out under the protection of inert gases, or carried out in the environment of ¾ gas or N2 gas, or carried out in vacuum environment, thereby being beneficial to improve the welding quality of braze welding.
