Embodiment

[0045] 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 according to the shape and size of the convex vacuum glass to be produced, drill a through hole at the corner of the upper glass 1 as the air outlet 3, and drill a hole around the periphery of the lower glass 2 and the air outlet. 3, a sealing groove 6 is set up at the corresponding place, and the edge grinding, chamfering, cleaning and drying are carried out, and the sealing strip 5 is prepared by mechanical spraying technology on the peripheral welding part of the upper glass 1 and the periphery of the suction port 3, and is applied on the upper and lower sides by a glue dispenser. Prepare the support 9 from the glass, and then make a silver paste layer 8 on the sealing strip around the...

Abstract

High-temperature-sheet-combination sealed convex vacuum glass with edges sealed by sealing grooves is disclosed. The convex vacuum glass comprises upper glass and lower glass which are convex glass. The upper glass is provided with one to four air extracting holes. The peripheries of the upper glass and each air extracting hole are provided with sealing strips. Corresponding positions of the periphery of the lower glass and each air extracting hole are provided with the sealing grooves. After being heated, the upper glass and the lower glass are subjected to sheet combination at a high temperature, and the peripheries of the upper glass and the lower glass are welded under elevated pressure by glass solder in a heating furnace. Each air extracting hole is automatically sealed by utilization of metal solder in a vacuum furnace. A sealed vacuum layer is formed between the upper glass and the lower glass. 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 convex vacuum glass with a high-temperature lamination sealing groove edge sealing 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 ...
