Embodiment 1

[0058] Embodiment one: according to figure 1 , figure 2 , image 3 Shown to make:

[0059] (1) Firstly, the flat glass or float glass 1 is preheated at a temperature gradually increased to 280°C-320°C.

[0060] (2) Partially heat the periphery 2 of flat glass and float glass to a softening temperature of 650°C-1150°C, which can be formed, and then bend the softened glass periphery 2 in a direction that forms a certain angle with the glass plane, Form the edged glass. And keep the flatness of the glass surface from being affected by heating and edge folding.

[0061] (3) Tempering the edged glass to form a tempered edged glass 5 with a single side opening formed by the face wall 3 and the side wall 4 .

[0062] (4) Place the tempered folded glass 5 with the opening upward, and place the pin 7 at the corresponding position on the inner surface 6 of the facing wall.

[0063] (5) Place the melted sealing low-temperature sealing material 9 on the sealing surface 8 of the sid...

Embodiment 2

[0066] Embodiment two: according to Figure 4 Shown to make:

[0067] (1) Preheat the tempered edged glass 5 at a temperature of 280°C-300°C, and then place the pin 7 at the corresponding position on the inner surface 6 of the facing wall, then place the separation layer 13 on the upper surface 10 of the pin, and make The periphery 14 of the separation layer is placed on the inner edge of the side wall sealing surface 8 or connected to the inner edge of the side wall sealing surface.

[0068] (2) Place the second layer pins 7 - 1 at corresponding positions on the surface 15 of the separation layer, so that the second layer pins 7 - 1 are aligned up and down with the first layer pins 7 .

[0069] (3) Place the melted sealing low-temperature sealing material 9 on the side wall sealing surface 8, so that the sealing low-temperature sealing material 9 is connected to the periphery 14 of the separation layer, and completely wraps between the periphery 14 of the separation layer an...

Embodiment 3

[0071] Embodiment three: according to Figure 5 Shown to make:

[0072] (1) After placing the pin 7 at the corresponding position on the inner surface 6 of the facing wall, place the separation layer 13 on the upper surface 10 of the pin, and make the inner surface 16 of the side wall around the periphery 14 of the separation layer meet.

[0073] (2) At the periphery where the periphery of the separation layer 14 is connected to the inner surface 16 of the side wall, a low-temperature sealing material 17 for the separation layer with a melting temperature of 300° C. to 500° C. is placed, so that the periphery of the separation layer 14 is hermetically sealed on the side wall. The inner surface of the wall 16 .

[0074] (3) Place the second-layer column pins 7-1 at corresponding positions on the surface 15 of the separation layer, so that the second-layer column pins 7-1 and the first-layer column pins 7 are aligned up and down. Repeat (1)(2)(3) item assembling method, that i...

Abstract

Disclosed is a manufacturing method for tempered vacuum glass. The manufacturing method has the remarkable advantages that the method is simple, convenient and reliable, and industrial production is facilitated; by the unique method based multiple thick vacuum layers, products can have excellent heat insulation performance and high safety and reliability, so that the detect that the low safety ofexisting vacuum glass restricts industrial development is overcome; the method has great significance in the development of projects, the products and the industry. The products with a wide market application range have the advantages that heat insulation properties are set correspondingly through thickness and number adjustment of the vacuum layers and adjustment of the vacuum degree, and the energy conservation requirements of passive buildings and zero-energy-consumption buildings that require the energy consumption of building doors, windows, curtain walls, walls and roofs is reduced by 75% can be completely met; when separation layers are made from glass, the products have high transparency and good imaging performance, and are mainly applied to building doors, windows, curtain wallsand domes; when the separation layers are made from aluminum sheets or stainless steel sheets, the products are opaque, and are mainly applied to heat-insulting decorations for opaque building curtainwalls, walls and roofs; the durability of the products is more than 100 times that of the existing vacuum glass.

Description

technical field [0001] The invention belongs to the technical field of building material production, and in particular relates to a manufacturing method of tempered vacuum glass and a tempered vacuum glass manufactured by the manufacturing method. Background technique [0002] Existing vacuum glass. [0003] The current manufacturing process of vacuum glass is to arrange supports on tempered flat glass, and then spread solder on the edge between two parallel tempered flat glasses, then weld and seal at high temperature, and finally pump air to form a vacuum. Existence: When the solder is melted at high temperature at the edge of two parallel tempered flat glasses, the performance of the tempered glass will be seriously reduced, and even the tempering performance will be lost, especially the peripheral strength of the tempered flat glass will be greatly reduced. Cracks start to develop around the perimeter, leading to the main cause of chipping. If the vacuum glass with mul...
