Metal-welded convex double-vacuum-layer glass with sealing strips, sealing grooves, and mounting hole.

Abstract

The invention relates to metal-welded convex double-vacuum-layer glass with sealing strips, sealing grooves, and a mounting hole. The glass comprises upper glass, lower glass and intermediate glass. The glass is characterized in comprising the mounting hole. The upper glass and the lower glass are convex glass. The intermediate glass is planar glass. Sealing strips are provided at the peripheries of the upper surfaces of the upper glass and the intermediate glass, and at the periphery of the mounting hole, on the upper surfaces of the upper glass and the intermediate glass. Sealing grooves and sealing strips are provided at the peripheries of the upper surfaces of the intermediate glass and lower glass, and at the periphery of the mounting hole, on the upper surface 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 hole is also automatically sealed by using the metal solder. Two sealed vacuum layers are formed between the three pieces of glass. The vacuum glass and the preparation method have simple process. The prepared vacuum glass and tempered vacuum 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 glass can be enhanced.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex double-vacuum-layer glass with sealing strip grooves and installation holes welded by metal 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 exhaust port. The edge sealing of this vacuum g...

Problems solved by technology

[0004] The applicant of the present invention disclosed a series of vacuum glass without air extraction port and its manufacturing method in the patent of vacuum glass applied in October, 2012. At high temperature and vacuum, the air and moisture absorbed by the solder, the volatile substances in the solder, the gas dissolved in the solder during the production process, and the decomposition of some oxides in the solder will cause a large number of bubbles in the solder , which greatly weakens the performance of the solder, especially the airtightness, which greatly affects the feasibility of this method
