Embodiment 1

[0043] Example 1: see figure 1, The convex low-altitude glass is composed of an upper glass 1 and a lower glass 2, the peripheries of the two pieces of glass are welded together by low-temperature glass solder 4, and the middle is a low-altitude layer. The production method is as follows: First, cut two pieces of flat glass according to the shape and size of the convex low-altitude glass to be made, drill a through hole at the corner of the upper and lower glass respectively to form the installation hole 3, and install the hole 3 around the periphery of the lower glass 2. Sealing groove 6 is provided on the periphery of 3, and edge grinding, chamfering, cleaning and drying are carried out, and sealing strip 5 is prepared by mechanical spraying technology at the peripheral welding place of upper glass 1 and the periphery of mounting hole 3, and is applied on the upper and lower glass with a glue dispenser. Prepare the support 7; secondly, put the upper and lower pieces of glass...

Embodiment 2

[0044] Example 2: see figure 2 The convex low-altitude glass is composed of an upper glass 1 and a lower glass 2. The two pieces of glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass. The production method is as follows: firstly, the convex low-altitude glass is cut according to the shape and size of the produced convex low-altitude glass. A piece of flat glass and a piece of low-emissivity glass of the required size, choose the low-emissivity glass as the lower glass 2, drill a through hole at the corner of the upper and lower glass to form the installation hole 3, and set up a seal around the periphery of the lower glass 2 and the installation hole 3 Groove 6, and carry out edge grinding, chamfering, cleaning and drying, and use screen printing technology to print sealing strips on the peripheral welding place of upper glass 1 and the periphery of mounting hole 3; secondly, put two pieces of glass into two forming In the mold, the forming ...

Abstract

A convex low-pressure glass having sealing grooves and mounting holes includes an upper glass and a lower glass. The convex low-pressure glass is characterized by being provided with the mounting holes. The upper glass and the lower glass are convex glasses. Peripheries of the upper glass and the mounting holes are provided with sealing bars and the peripheries of the lower glass and the mounting holes are provided with the sealing grooves. The peripheries of the upper glass and the lower glass are automatically welded to each other through a low-temperature solder in an edge-sealing oven while the mounting holes are sealed automatically through the low-temperature solder. A sealed low-pressure layer is formed between the upper glass and the lower glass. The low-pressure glass is simple in manufacturing technology. The low-pressure glass and a tempered low-pressure glass are easy to install and use, are ensured in air tightness and are enhanced in strength, heat-insulating performance and sound-insulation performance.

Description

technical field [0001] The invention relates to the technical field of glass deep processing, in particular to a convex low-altitude glass with a sealing groove and an installation hole and a manufacturing method thereof. Background technique [0002] Most of the existing insulating glass is a glass product in which two or more pieces of glass are separated by a spacer frame with a desiccant and sealed with an organic sealant. Due to the organic sealant itself containing moisture, poor anti-aging performance, poor air tightness and other reasons, the insulating glass often fails, which seriously affects the service life of the insulating glass. The air in the air layer of insulating glass is sealed between two pieces of glass. When the external temperature is high, the pressure is greater than the atmospheric pressure, and the glass is convex; when the external temperature is low, the pressure is lower than the atmospheric pressure, and the glass is concave. The normal serv...
