Problems solved by technology

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.
[0004] The air in the air layer of insulating glass is sealed between two pieces of glass. Due to the change of external temperature, the pressure of the air layer will change. When the external temperature is high, the pressure is greater than atmospheric pressure and the glass is convex. When the external temperature is low, the pressure is lower than atmospheric pressure. , The glass is concave, resulting in the so-called "breathing" phenomenon, which affects the normal service life of the insulating gl...

Embodiment 1

[0068] Embodiment 1: see figure 1 The low-altitude glass is composed of two pieces of glass, one of which is low-emissivity glass, and its production method is as follows: first, cut a piece of flat glass and a piece of low-emission glass of the required size according to the shape and size of the low-altitude glass to be produced, and perform edge grinding, After chamfering, film removal, cleaning and drying, the low-temperature glass powder paste is printed on the glass to form an edge banding frame by printing technology. The upper glass has one edge banding frame, and the lower glass has two edge banding frames. The size of the upper glass edge seal frame is between the lower glass edge seal frames. After the upper and lower glass are combined, the edge seal frame of the upper glass can be embedded between the edge seal frames of the lower glass; the upper and lower glass are dried Finally, print or spray commercially available silver paste on the position of the edge band...

Embodiment 2

[0071] Example 2: see figure 2 , one of the two pieces of low-altitude glass is low-emissivity glass, and the other is tempered glass or semi-tempered glass. Radiation glass, after grinding, chamfering, removing film, after cleaning and drying, use a spray gun to spray low-temperature glass powder paste on two pieces of glass to make an edge banding frame, in which the upper glass has an edge banding frame, the lower glass There are two edge sealing frames, the size of the upper glass edge sealing frame is between the two edge sealing frames of the lower glass, after the upper and lower glass are combined, the edge sealing frame of the upper glass can be embedded Between two edge banding frames; after the upper and lower glass are dried, print or spray a layer of paste containing low-temperature glass powder on the position of the edge banding frame, and then print or spray a layer of commercially available silver paste as a transition layer Next, put the upper glass into th...

Embodiment 3

[0076] Embodiment 3: see image 3 , the two pieces of glass of the low-altitude glass are tempered glass or semi-tempered glass, one of which is low-emissivity glass, and its production method is as follows: first, a piece of flat glass and a piece of low-emissivity glass are cut according to the shape and size of the low-altitude glass to be produced. , carry out edge grinding, chamfering, film removal, after cleaning and drying, use nylon screen to print low-temperature glass powder paste on two pieces of glass to form an edge banding frame, in which the upper glass has an edge banding frame and the lower glass There are two edge sealing frames, the size of the upper glass edge sealing frame is between the two edge sealing frames of the lower glass, after the upper and lower glass are combined, the edge sealing frame of the upper glass can be embedded Between two edge banding strip frames; secondly, put two pieces of glass into two forming molds respectively, the forming mol...

Abstract

The invention relates to low vacuum glass. The low vacuum glass is characterized in that each of upper glass and lower glass is convex glass, edge sealing strip frames are arranged on the welded peripheries of the upper glass and the lower glass, and the upper glass and the lower glass are welded together by utilizing metal or alloy solder in a microwave oven; and the manufacturing of the low vacuum glass is simpler and more convenient, and the matching of the upper and the lower edge sealing strip frames can ensure a good sealing effect. The method has the advantages of simpleness in manufacturing process, low cost, high production efficiency, reliability in sealing and connecting and good sealing effect; the one-step large-batch preparation of the low vacuum glass can be realized by utilizing the technology, and the manufactured low vacuum glass is strong in resistance to wind pressure and good in heat insulation and sound insulation; and the method can be used for manufacturing the ordinary low vacuum glass and is particularly suitable for manufacturing tempered low vacuum glass.

Description

technical field [0001] The invention relates to the processing and manufacturing of low-altitude glass, in particular to a method for making low-altitude glass and its products. Background technique [0002] With the strengthening of environmental protection and energy saving awareness, insulating glass has been widely promoted and applied, effectively improving the thermal insulation and sound insulation performance of doors and windows. The distance between two pieces of flat glass of insulating glass, that is, the thickness of the air layer determines the effect of heat preservation and sound insulation. The thicker the air layer, the better the heat preservation and sound insulation effect, but increasing the thickness of the air layer will increase the thickness of the door and window frames. Therefore, it will increase the production cost of doors and windows; other methods, such as the use of coated glass, film sticking and filling inert gas in the middle of insulatin...
