Problems solved by technology

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

Embodiment

[0040] Example: Referring to the attached drawings, the vacuum glass is composed of upper glass 1 and lower glass 2. The two glasses are tempered glass or semi-tempered glass, and one of them is low-e glass. The manufacturing method is as follows: First, according to the shape of the vacuum glass made Cut a piece of flat glass and a piece of low-e glass of the required size and size, choose the low-e glass as the lower glass 2, drill a through hole at the corners of the upper glass 1 and the lower glass 2 as the mounting hole 3, on the periphery of the lower glass 2. A sealing groove 6 is opened at the corresponding place of the mounting hole 3 and edging, chamfering, cleaning, and drying are performed. The sealing strip is made by screen printing or dispensing technology at the periphery of the upper glass 1 and the periphery of the mounting hole 3 And make the support 8 at the same time; secondly, the two glasses are sent into the tempering furnace for air-cooled tempering to ...

Abstract

Glass-welded plain vacuum glass provided with edges sealed by sealing grooves and provided with mounting hole(s) is disclosed. The plain vacuum glass comprises upper glass and lower glass, and is characterized in that: the plain vacuum glass is provided with the mounting hole(s), the number of the mounting hole(s) is 1-4; the peripheries of the upper glass and each mounting hole are provided with sealing strips; corresponding positions of the periphery of the lower glass and each mounting hole are provided with the sealing grooves; after being rapidly heated, the upper glass and the lower glass are subjected to sheet combining at a high temperature, and the peripheries of the upper glass and the middle glass and the periphery of each mounting hole are welded under elevated pressure by glass solder in a vacuum furnace; one sealed vacuum layer is formed between the upper glass and the lower glass; and supports arranged in a point array are disposed in the vacuum layer. The vacuum glass and a manufacturing method thereof are simple in process and high in production efficiency. The manufactured vacuum glass eliminates edge sealing stress and maintains tempered characteristics of tempered glass. Tempered vacuum glass can be produced in a large scale, and the service lifetime of the tempered vacuum glass can be prolonged.

Description

Technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a flat vacuum glass with mounting holes welded to the 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 the construction field; but there are also obvious The shortcomings are mainly low production efficiency, low production capacity, and inability to produce toughened vacuum glass, which limits its promotion and application in a wider range; the existing large-scale production of vacuum glass uses high temperature (430-480°C) atmospheric pressure The production process of under-sealing and low-temperature (180-300℃) vacuuming and then sealing. Because the edge-sealing temperature needs to be kept for a per...
