Embodiment 1

[0042] Embodiment one: if figure 1 , figure 2 , image 3 As shown, (1) first use the cohesive soil in the mandrel mold, which can still maintain its shape in the atmosphere of 300 ° C - 780 ° C, and become loose, melted, and slurry after contact with water or use soil as the base The mixture of cementing materials completes the manufacture of the temperature-resistant mandrel; (2) In the atmosphere of 300°C-780°C, heat-melt the low-melting point glass frit 8 placed in the mold 3 into a fluid or plastic state glass frit 2 Place the temperature-resistant mandrel 1 in the glass frit 2 through the positioning rod 4 covered with the separation ring 5, so that there is a gap of 3mm-6mm between the side wall 29 of the temperature-resistant mandrel and the mold 3, and make the glass frit 2 wrap the temperature-resistant mandrel 1 and fill the pin holes 6, demould after cooling to obtain a plate body with a temperature-resistant mandrel 1 inside; (3) remove the separation ring 5, th...

Embodiment 2

[0043] Embodiment two: if Figure 4 As shown, (1) Spread a layer of low-melting point glass frit 8 with a thickness of 3 mm to 10 mm on the inner surface of the mold 3, and place the temperature-resistant mandrel 1 on the mold 3 through the positioning rod 4 covered with the separation ring 5 The surface of the low-melting-point glass frit 8 of the plate body sprinkled in the middle, and a gap of 3 mm to 6 mm is left between the side wall 29 of the temperature-resistant mandrel and the mold 3, and then the accurately measured low-melting-point glass frit 8 of the plate body is placed on the heat-resistant mandrel. The gap between the warm mandrel 1 and the mold 3, the pin hole 6 and the upper surface of the temperature-resistant mandrel 1; (2) heat-melt the low melting point glass frit 8 of the plate body in the atmosphere of 300°C-780°C to form a fluid glass frit, so that the glass frit is filled The gap between the temperature-resistant mandrel 1 and the mold 3 and the pin h...

Embodiment 3

[0044] Embodiment three: as Figure 5 As shown, (1) on the separation layer 15 made of 0.05mm - 0.3mm metal sheet, open a separation layer pin with a diameter of 2mm - 6mm at the position corresponding to the pin hole 6 on the temperature-resistant mandrel 1 Holes 16; (2) sandwich a separation layer 15 between two or more heat-resistant mandrels 1, so that the pin holes of the temperature-resistant mandrel 1 and the separation layer 15 are connected to form a through-pin hole 18, and the periphery of the separation layer 17 Leave or protrude from the side of the temperature-resistant mandrel 1 by 2 mm——10 mm; (3) Repeat this, that is, complete the layout of the multi-layer temperature-resistant mandrel 1 and the intervening layer 15 to form a heat-resistant mandrel module; (4) at 300°C——780 ℃ atmosphere, heat-melt the low-melting-point glass frit 8 put into the mold 3 into a fluid frit 2, and place the temperature-resistant core module in the frit 2 through the positioning rod...

Abstract

Significant advantages of the present invention: excellent air tightness, excellent thermal insulation performance; especially "safety" is extremely excellent and reliable: the whole board body is a complete and integrated board body formed at one time when the glass is hot-melted into a fluid or plastic state, fundamentally To put an end to the chronic problems of air leakage and separation around the existing vacuum glass, the setting of the reflective separation layer further strengthens the structure of the panel, endowing the product with the safety and reliability of the same life as the building. The fiber and fiber net inside the board can effectively enhance the toughness of the board and improve the impact strength; it has a wide range of applications: non-transparent products are used for insulation and decoration of building walls and roofs, and light-transmitting and opaque products are used for thermal insulation building curtain walls. Transparent and translucent products are used for doors, windows, and domes that require high thermal insulation performance; the installation method is convenient, safe and reliable, and since the thickness of the board body is between 25mm and 90mm, it is beneficial to set up installation grooves, installation edges and board seams for heat preservation.

Description

technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a method for making integrally formed vacuum glass and a safety vacuum glass. Background technique [0002] The existing vacuum glass is prefabricated at a high temperature of 800-1470°C between two pieces of flat glass or between a flat glass and a metal plate, and a prefabricated support is provided to form a 0.1-0.2 gap between the two plates. mm thick vacuum layer. When making, first place a support on the surface of a piece of pre-manufactured flat glass, then accurately place a low-melting point sealing material around the entire periphery of the glass, and then place another piece of glass or metal plate on the support and sealing material , the sealing material is melted by flame or electric heat to complete the airtight sealing of the entire periphery of the glass plate and the glass plate, and the glass plate and the metal plate to form a combined ...
