Metal-welded sealed convex double-vacuum-layer glass with installing holes and edges sealed by sealing grooves and strips

Abstract

The invention relates to a metal-welded sealed convex double-vacuum-layer glass with installing holes and edges sealed by sealing grooves and strips, which comprises an upper glass, a lower glass and an intermediate glass, the installing holes and extraction openings are combined as an integral body, 1-4 installing holes are arranged, the sealing strips are provided at lower surfaces of the upper glass, the intermediate glass and circumference of the extraction opening, the sealing grooves and the sealing strips are arranged on the upper surface periphery of the intermediate glass and the lower glass as well as the position corresponding to the extraction opening, three glasses are rapidly heated, the circumference can be welded together by pressurizing through an alloy solder in an atmosphere heating furnace, the extraction opening is enclosed in a vacuum furnace by a metal solder, and two enclosing vacuum layers are formed between the upper glass and the intermediate glass as well as between the intermediate glass and the lower glass. The vacuum glass and its production method have the advantages that the process is simple and the production efficiency is high, the prepared vacuum glass can eliminate the stress of the sealed edge and can keep the toughening characteristic of the toughened glass, so that toughened vacuum glass can be massively produced, and its usage life is increased.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex-surface double-vacuum-layer glass with mounting holes on the edges of grooves sealed by metal welding sealing strips and a manufacturing method thereof. Background technique [0002] As a new type of glass with the most energy-saving potential, vacuum glass has achieved large-scale production after more than ten years of research and development, and has been well applied in many fields, especially in the construction field; but there are also obvious The shortcomings are mainly low production efficiency, small production capacity, and inability to produce tempered vacuum glass, etc., which limit its popularization and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) normal pressure The production process of lower edge sealing, low temperature (180-300°C) vacuuming and sealing, because it ne...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a convex double-vacuum laminated glass with a metal welded sealing strip groove edge sealing and a mounting hole and a manufacturing method thereof for the defects existing in the existing vacuum glass. This vacuum glass and the manufacturing method thereof The process is simple and the production efficiency is high. The prepared tempered vacuum glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of the tempered glass. It can produce tempered vacuum glass in large quantities and increase its service life.
