Embodiment 1

[0044] Embodiment 1: see figure 1, The convex low-altitude glass is composed of upper glass 1 and lower glass 2, the periphery of the two pieces of glass is welded together by low-temperature 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 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, the periphery of mounting hole 3 and the periphery of lower glass sealing groove, And use a dispensing machine to prepare support 7 on the upper and lower glass; secondly, put the upper ...

Embodiment 2

[0045] 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 edging, chamfering, cleaning, and drying, and use screen printing technology to print sealing strips on the periphery of the upper glass 1, the periphery of the mounting hole 3, and the periphery of the upper sealing groove 6 of the lower glass 2; Put two pieces of glas...

Abstract

The invention relates to convex low-pressure hollow glass with sealing strips, sealing grooves and a mounting hole. The glass comprises upper glass and lower glass, and is characterized in comprising the mounting hole. The upper glass and the lower glass are convex glass. Sealing strips are provided at the upper glass and at the periphery of the mounting hole. Sealing grooves are sealing strips are provided at the periphery of the lower glass and at the periphery of the mounting hole. The peripheries of the upper and lower glass are automatically welded together by using a low-temperature solder in an edge-sealing furnace. The mounting hole is automatically sealed by using a low-temperature solder. A sealed vacuum layer is formed between the upper glass and the lower glass. The low-pressure hollow glass and the preparation method thereof have simple process. Prepared low-pressure hollow glass and tempered low-pressure hollow glass are beneficial for mounting and application. Air-tightness of the low-pressure hollow glass can be ensured. Strength, thermal insulation performance and sound insulation performance of the glass can be enhanced.

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 strip 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 norma...
