Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a convex vacuum glass with sealing strip and edge sealing metal welded with mounting 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 tempered vacuum 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 vacuum glass in large quantities and increase its service life.

Embodiment

[0044] Example: see figure 1 , The convex vacuum glass is composed of upper glass 1 and lower glass 2, the periphery of the two pieces of glass is welded together by metal solder 7, and the middle is a vacuum layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the vacuum glass to be produced, drill a through hole at the corner of the upper glass 1 and the lower glass 2 as the installation hole 3, and grind the upper and lower glass. Edge, chamfering and cleaning, drying, use mechanical spraying technology to prepare sealing strips 5 and 4 at the peripheral welding place of the upper and lower glass and the periphery and corresponding positions of the mounting hole 3, and prepare the support 8 on the upper and lower glass with a dispenser. Make a silver paste layer 6 on the sealing strip in contact with the solder and the surface of the glass; secondly, put the upper and lower pieces of glass in...

Abstract

The invention relates to a convex vacuum glass having installing holes by metal welding at sealed edge of a sealing strip, which comprises an upper glass and a lower glass, the installing holes are provided, 1-4 installing holes are provided, at least a sealing strip is respectively provided at circumference of the upper glass and the installing hole, at least two sealing strips are provided at circumference of the lower glass, at least a sealing strip is arranged at the lower glass corresponding to the installing hole, the sealing strip of the upper glass is inserted between sealing strips of the lower glass, the upper glass and the lower glass are rapidly heated and laminated at high temperature, the circumference can be welded together by pressurizing through a metal solder in a vacuum 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, so that toughened vacuum glass can be massively produced, 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 vacuum glass with sealing strip edge sealing metal welded with mounting holes 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 tim...
