Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a flat double low-altitude glass welded with sealing strip groove edge sealing glass and its manufacturing method for the defects of the existing low-altitude glass. This low-altitude glass and its manufacturing method are simple in process, High production efficiency, the prepared tempered low-altitude glass can not only reduce or eliminate 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 1

[0033] Embodiment 1: see figure 1, the plane double low-altitude glass is composed of upper glass 1, middle glass 3 and lower glass 2, at least the upper and lower glass of the three pieces of glass are tempered glass or semi-tempered glass, and the lower glass 2 or \ and middle glass 3 are also low-emissivity Glass, its manufacturing method is as follows: first according to the shape and size of the flat double low-altitude glass that needs to be made, cut three pieces of flat glass of the required size, and open the sealing groove 6 at the upper surface peripheral welding place of the middle glass 3 and the lower glass 2 , and carry out edging, chamfering, cleaning and drying treatment to the three pieces of glass; secondly, print the sealing strip 5 on the lower surface periphery of the upper glass 1 and the middle glass 3 and the periphery of the sealing groove 6, and print on the lower surface of the upper glass 1 Print or glue on the upper surface of the lower glass 2 to...

Abstract

The invention relates to a glass-welded plane 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 provided at lower surfaces of the upper glass and the intermediate glass, the seal groove 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 plane 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 high...
