Problems solved by technology

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

Embodiment

[0040] Example: see figure 1 , The convex vacuum glass is composed of an upper glass 1 and a lower glass 2, the periphery of the two pieces of glass is welded together by glass solder 4, 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 to form a suction port 3, and grind and chamfer the upper and lower glass And clean, dry, utilize mechanical spraying technology to prepare sealing strip 5 and 6 at the peripheral welding place of upper and lower glass and the periphery of air inlet 3 and corresponding place, and prepare support 8 on upper and lower glass with dispenser; Put the glass into the mold, put it in the hot bending furnace, heat up to the temperature of glass softening 550-750 ℃, rely on the gravity of the glass itself to make the glass downward to form a convex surface...

Abstract

The invention relates to a glass-welded sealed convex vacuum glass with edges and extraction openings sealed by sealing strips, which comprises an upper glass and a lower glass, 1-4 extraction openings are arranged on the upper glass, at least a sealing strip is provided at circumference of the upper glass and the extraction opening, at least two sealing strips are respectively provided at circumference of the lower glass and the extraction opening, the sealing strip of the upper glass is inserted between the 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 glass solder in a heating furnace, and the extraction opening is performed with on-line enclosing by using molten glass in a continuous 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 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 vacuum glass edge-sealed with a glass welding sealing strip 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 the edge seal...
