Patent ID: 8899472

Claim:
A method for sealing a vacuum glass comprising the following steps: 1) preparing metallized layers on surfaces to be sealed at edges of two glass plates via a sintering process; and 2) connecting a metal sealing sheet between the metallized layers of the two glass plates to be sealed in an air-tight manner to realize air-tight sealing of the edges of the two glass plates; wherein the metal sealing sheet comprises a U-shaped metal sheet and wherein two sides of the U-shaped metal sheet are respectively connected with the metallized layers on the two glass plates to be sealed in an air-tight manner; wherein one side of the U-shaped metal sheet is positioned between the two glass plates to be sealed and connected with the metallized layer on an inner surface of one glass plate in an air-tight manner by a metal brazing process or an ultrasonic brazing process, and the other side of the U-shaped metal sheet goes around an edge of the other glass plate and then is connected with the metallized layer on an outer surface of the glass plate in an air-tight manner by the metal brazing process or the ultrasonic brazing process.
