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 and edge-sealing glass and its manufacturing method in view of the defects existing in the existing low-altitude glass. High efficiency, the prepared tempered low-altitude glass can not only reduce or eliminate the edge sealing stress but also maintain the tempered characteristics of tempered glass, can produce tempered low-altitude glass in large quantities, and can increase its service life

Embodiment

[0034] Embodiment: Referring to the accompanying drawings, the convex double low-altitude glass is composed of an upper convex glass 1, an intermediate glass 3 and a lower convex glass 2. The production method is as follows: first, cut three pieces of flat glass of required size according to the shape and size of the convex double low-altitude glass to be produced, and perform edge grinding, chamfering, cleaning and drying on the three pieces of glass; The sealing strips 5 and 6 are prepared by spraying on the corresponding parts of the peripheral welding of glass 1, lower glass 2 and middle glass 3, and the middle glass 3 is directly sent into a high-temperature furnace for high-temperature treatment. The softening temperature of the glass is 550-750°C. Depending on the gravity of the glass itself or the applied external force, the glass will form a convex surface downwards, and then undergo tempering treatment; again, install between the two sealing strips 6 around the middle...

Abstract

The invention relates to a glass-welded convex double-low altitude-layer glass with edge sealed by sealing strips, which comprises an upper glass, a lower glass and an intermediate glass, at least a sealing strip is provided at lower surface circumference of the upper glass and the intermediate glass, at least two sealing strips are provided at upper surface circumference of the intermediate glass and the lower glass, three glasses are rapidly heated, and the circumference can be welded together by pressurizing through a glass solder in a heating furnace. 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, and 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 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 high; comp...
