Embodiment

[0038] Embodiment: Referring to the accompanying drawings, the convex double vacuum laminated glass consists of an upper convex glass 1 , an intermediate glass 3 and a lower convex glass 2 . Its production method is as follows: First, according to the shape and size of the convex double vacuum laminated glass to be produced, three flat glasses of the required size are cut, and a sealing groove 6 is opened at the upper surface peripheral welding place of the middle glass 3 and the lower glass 2, and Edge grinding, chamfering, cleaning and drying are performed on the three pieces of glass; secondly, sealing strip 5 is prepared by spraying on the corresponding positions around the lower surface of the upper glass 1 and the middle glass 3, and the middle glass 3 is directly sent into a tempering furnace for tempering treatment , put the upper and lower pieces of glass into the mold, heat up to the temperature of glass softening 550 ~ 750 ℃, rely on the gravity of the glass itself o...

Abstract

The invention relates to a glass-welded convex surface double-vacuum-layer glass with edge sealed by sealing grooves, which comprises an upper glass, a lower glass and an intermediate glass, the sealing strips are arranged on the upper surfaces of the upper glass and the intermediate glass, the seal grooves 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 vacuum furnace, and two 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 double-vacuum-layer glass welded with sealing 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; 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 needs to be kept warm for a period of time at t...
