Glass-welded convex surface double-low altitude-layer glass with edge sealed by sealing grooves and strips and production method thereof

Abstract

The invention relates to a glass-welded convex surface double-low altitude-layer glass with edge sealed by sealing grooves and strips, which comprises an upper glass, a lower glass and an intermediate glass, the sealing strips are arranged on lower surfaces of the upper glass and the intermediate glass, the seal grooves and the sealing strips are arranged on the upper surface circumference of the intermediate glass and the lower glass, three glasses are rapidly heated, the circumference can be welded together by pressurizing through a glass solder in a heating furnace, and two enclosing low-altitude 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 double low-altitude layer glass welded with sealing strip groove edge sealing glass 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; High vacuum not only requires a large investment in equipment, but also has high difficulty in production, low production efficiency, and small production capacity, which limits its application in a wider range; low-altitude glass is a new type of glass between insulating glass and vacuum glass , compared with vacuum glass, the production process of low-altitude glass is simple, does not require vacuuming, equipment investment is small, and production efficiency is hig...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of convex double low-altitude glass welded with sealing strip groove edge sealing glass and its manufacturing method in view of the defects existing in the existing low-altitude glass. This low-altitude glass and its manufacturing method are simple in process, The production efficiency is high. The prepared tempered low-altitude 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 low-altitude glass in large quantities and increase its service life.
