Problems solved by technology

[0004] The existing vacuum flat glass has the following deficiencies: First, because the edge sealing solder is in a molten state after being heated to about 350°C, it has a tendency to flow and spread on the glass surface, so its thickness is limited, limiting The thickness of the vacuum chamber is limited, and the thickness of the current vacuum chamber can only be 0.2~0.5mm
In order to keep the vacuum in the vacuum chamber from being destroyed for a long time, the volume of the getter should not be too small. In the prior art, in order to smoothly put a large enough getter in a space with a height of only 0.2-0.5mm, Generally, it is necessary to pre-process grooves on the upper flat glass and the lower flat glass, which will reduce the local strength of the glass, and the manufacturing process is more troublesome
Third, during the sintering process, due to the flowing characteristics of the solder, under the extrusion of the upper plate glass and the lower plate glass, the inside of the edge seal will be uneven, and irregular wavy or jagged edge seals will easily appear, affecting beautiful

Embodiment 1

[0034] Such as figure 1-shown in 4, is a kind of hexahedral vacuum glass, comprises upper floor plate glass 1 and lower floor plate glass 5, and upper floor plate glass 1 and lower floor plate glass 5 are all rectangular, is provided with between upper floor upper floor plate glass 1 and lower floor plate glass 5 Several support columns 4, the support columns 4 can be evenly distributed, in order to reduce the heat transfer coefficient, the support columns 4 can be made of quartz, and a glass isolation ring 2 is arranged between the upper plate glass 1 and the lower plate glass 5 periphery, and the support columns 4 The difference between the height of the glass spacer 2 and the thickness of the glass spacer 2 is 0~0.3mm, the thickness of the glass spacer 2 is preferably 3~30mm, for example, 3mm, 8mm, 12mm, 20mm, 30mm, etc., the glass spacer 2 of this size range It is convenient to manufacture, and the glass with standard thickness specifications is used to manufacture the gla...

Embodiment 2

[0045] Such as Figure 5 As shown, it is yet another hexahedral vacuum glass, comprising an upper plate glass 1 and a lower plate glass 5, a number of support columns 4 are arranged between the upper plate glass 1 and the lower plate glass 5, and the upper plate glass 1 and the lower plate glass A glass isolation ring 2 is provided between the periphery of the glass 5, and sintered edge sealing solder 8 is respectively provided between the upper surface of the glass isolation ring 2 and the upper plate glass 1, and between the lower surface of the glass isolation ring 2 and the lower plate glass 5. , the glass isolation ring 2, the upper plate glass 1 and the lower plate glass 5 form a vacuum chamber;

[0046] The hexahedral vacuum glass can be manufactured according to the following steps:

[0047] 1) Cut glass strips of equal thickness, and then bend or weld them in a molten state to form a glass isolation ring 2. The length of the four sides of the glass isolation ring 2 c...

Abstract

The invention discloses a hexahedral vacuum glass in the technical field of glass. The hexahedral vacuum glass comprises upper-layer flat glass and lower-layer flat glass; a plurality of supporting pillars are arranged between the upper-layer flat glass and the lower-layer flat glass; a glass isolating ring is arranged between the peripheries of the upper-layer flat glass and the lower-layer flat glass; a sintered edge-sealing solder is respectively arranged between the upper surface of the glass isolating ring and the upper-layer flat glass and between the lower surface of the glass insolating ring and the lower-layer flat glass; the glass isolating ring, the upper-layer flat glass and the lower-layer flat glass form a vacuum cavity; and the vacuum cavity is isolated from the exterior by a sealed suction nozzle. The manufacturing process of the vacuum glass is as follows: manufacturing the glass isolating ring, arranging the suction nozzle, arranging the edge-sealing solders, laying the flat glass and the supporting pillars, and sintering under a vacuum condition to obtain the product. The hexahedral vacuum glass device has more excellent sound-insulation and heat-insulation effects than the vacuum flat glass in the prior art, attractive in appearance and convenient to place a gettering piece.

Description

technical field [0001] The invention relates to a vacuum glass and a manufacturing method thereof, in particular to a vacuum glass with a relatively thick vacuum cavity and a manufacturing method thereof. Background technique [0002] Due to its good heat insulation and sound insulation effects, vacuum glass is currently being used in an expanding range. The existing vacuum flat glass, its structure mainly includes an upper flat glass and a lower flat glass. Between the upper flat glass and the lower flat glass There are a number of supporting columns evenly distributed between them, edge-sealing solder is provided around the upper plate glass and the lower plate glass, and the closed space formed between the edge-sealing solder, the upper plate glass and the lower plate glass is a vacuum cavity; An air getter is arranged, and an air suction nozzle is also arranged on the upper plate glass. [0003] When the vacuum flat glass is manufactured, it is necessary to set solder o...
