Embodiment Construction

[0019] figure 2 It is a structural schematic diagram of the vacuum glass 100 provided by the present invention. The vacuum glass 100 is composed of a micro-bump glass original sheet 110 and a flat glass original sheet 120, and then brazed and sealed (130) along its peripheral edges. The vacuum layer 140 formed therebetween is composed of the micro-bump glass original sheet. 110 is supported by the micro-bump support lattice 111 on the inner surface, and a getter 150 for absorbing residual gas is placed in the vacuum layer 140 .

[0020] The micro-bump glass original sheet 110 is flat glass with a micro-bump support lattice 111 evenly distributed on its inner surface. The contour shape of the micro-bumps can be a spherical crown, a spherical segment, a circular frustum, etc. Its size should be small enough that it cannot be easily noticed by people with normal vision; the diameter is usually less than 0.5mm, and the height is 0.1-0.2mm, and the height of all micro bumps must...

Abstract

The invention provides vacuum glass and a manufacture method thereof, characterized in that micro-salient-point supporting objects melted together with an original glass sheet are used to substitute for a traditional stainless steel supporting object distributing process, a low-temperature metal braze-welding technology without causing the anneal of the original toughened glass sheet is used for sealing edges, and a traditional vacuum-layer vacuumizing process and an edge-sealing process are simplified and integrated into an integrated vacuumizing and edge-sealing process. Compared with traditional vacuum glass and the manufacture method thereof, the vacuum glass and the manufacture method thereof, which are provided by the invention, have simple process, high yield, low equipment investment and production cost, better heat and sound insulation, better appearance and light transmittance, high safety reaching the use standard of high-rise buildings, and the like.

Description

Technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly glass. Background technique [0002] Vacuum glass is currently the best energy-saving transparent outer covering material. It has a series of advantages such as light weight, thin thickness, small heat transfer coefficient, good sound insulation effect, high wind pressure resistance, and long life. It is an ideal energy-saving building material. . However, due to its expensive production cost and the inability to reach the strength of toughened glass required by high-rise buildings, it has not yet been widely used. [0003] The above-mentioned shortcomings of the existing vacuum glass are caused by its design structure and production process. The basic structure of the existing vacuum glass is as figure 1 As shown, the two original glass sheets are separated by a tiny support lattice, and the periphery is sealed with low-melting glass frit, and the glass exhaust p...
