Abstract:
1. A method for sealing curved vacuum glass, comprising the following steps: 1) preparing metal paste coatings on surfaces to be sealed on edges of two curved glass plates; 2) locally heating the positions of the metal paste coatings to sinter the metal paste coatings into two metallized layers bonded with the edges of the two curved glass plates, respectively; and 3) directly air-tightly joining the mutually corresponding two metallized layers on the two curved glass plates to be sealed by brazing two metal sheets with the two metallized layers on the edges of the two curved glass plates, respectively; wherein one of the two metal sheets is positioned between the two curved glass plates and is brazed onto one of the two metallized layers sintered on an inner surface of one of the two curved glass plates and the other of the two metal sheets is positioned onto an outer surface of the other of the two curved glass plates and is brazed onto the other of the two metallized layers sintered on the outer surface of the other of the two curved glass plates; and wherein edges of the two metal sheets protruding from the edges of the two curved glass plates are joined to the by a metal brazing process or an ultrasonic welding process.
