Metal-welded planar double-vacuum-layer glass with sealing strips and mounting holes

Abstract

The invention relates to metal-welded planar double-vacuum-layer glass with sealing strips and mounting holes. The glass comprises upper glass, lower glass and intermediate glass. The glass is characterized in comprising mounting holes. The upper glass, intermediate glass and lower glass are planar glass. At least one sealing strip is provided at each of the peripheries of the lower surfaces of the upper glass and the intermediate glass, and at each of the peripheries of the mounting holes on the lower surfaces of the upper glass and the intermediate glass. At least two sealing strips are provided at each of the peripheries of the upper surface of the intermediate glass and the lower glass, and at each of the peripheries of the mounting holes on the upper surfaces of the intermediate glass and the lower glass. The peripheries of the three pieces of glass are automatically welded together by using a metal solder in a vacuum furnace. The mounting holes are automatically sealed by using the metal solder. The planar double-vacuum-layer glass and the preparation method thereof have simple process. The prepared planar double-vacuum-layer glass and tempered planar double-vacuum-layer glass are beneficial for mounting and application. Air-tightness of the vacuum glass can be effectively ensured. Strength, thermal insulation performance and sound insulation performance of the vacuum glass can be enhanced.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a plane double-vacuum-layer glass with metal welding sealing strips and mounting holes and a manufacturing method thereof. [0002] Background technique [0003] 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 air extraction port. The edge sealing of this vacuum glass is...
