Abstract

The utility model relates to tailless vacuum glass. The tailless vacuum glass is characterized in that nonmetal supports made of zirconium oxide or zirconium silicate are arranged between two glass plates, each nonmetal support is spherical, annular or cylindrical with a height of 0.3mm, and the nonmetal supports are positioned and laid into a square array by the aid of screen printing technology. When used for common glass, the interval between each two nonmetal supports is 30*30mm, a vacuum cavity with the thickness of 0.33mm is formed between the two glass plates, a 6mm bleeder hole is arranged at one corner of the single glass plate, a fusible ring is fixed to the top of each bleeder hole and is melted by heating in a vacuum furnace to seal the bleeder hole, and the outer surfaces of the fusible rings are level with the outer surfaces of the glass plates or are concave. The tailless vacuum glass has the advantages that the tailless vacuum glass is formed by the aid of the fusible ring for sealing, heat conduction coefficient is reduced by adopting the nonmetal supports, each person can lay 1000-2000m of the tailless vacuum glass, and accordingly the tailless vacuum glass is high in productivity and low in cost.

Description

The anury vacuum glass

Technical field

The utility model relates to a kind of vacuum glass, particularly relates to the low anury vacuum glass of a kind of safety, productivity height and cost.

Background technology

As everyone knows, though China has made extensive work in the vacuum glass research and development, established the industrialization basis.But also there is a big difference to realize extensive industrialization.It is low to be mainly reflected in the production unit level of automation, and manual operation is many, thereby unstable product quality, and yield rate is low, and production line serialization degree is also low in addition, makes production efficiency low, and industrial scale does not increase yet, and output is little, and the cost height can't form benign cycle.In addition, two glass intermediary upholders mostly are metallic substance, heat-conduction coefficient is strengthened, so thermal conduction are fast; Lay with stationary support complex process difficulty big; Simultaneously after vacuumizing, a place of glass leaves little tail like the vacuum flask, easily breaks during transportation and leaks gas.Because yield rate is low, has improved cost, because industrial scale is little, various overhead costs strengthen, and cause the cost height again.

Summary of the invention

The utility model provides a kind of safety, productivity height and cost low anury vacuum glass for solving the technical problem that exists in the known technology.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it comprises layer glass plate, upholder, aspirating hole and vacuum chamber up and down, it is characterized in that: adopt nonmetal upholder up and down in the middle of the layer glass plate, the 6mm aspirating hole is opened the Yi Jiaochu at the monolithic sheet glass, the aspirating hole top is fixed with fusible link, is vacuum chamber up and down in the middle of the layer glass plate.

The utility model can also be by the following technical solutions:

The material of described nonmetal upholder is zirconium white or zirconium silicate;

The ball that is shaped as high 0.3mm, ring-type and the column of described nonmetal upholder adopt screen printing technique to be positioned to the nonmetal upholder of square formation formula lay, and when simple glass, its spacing is 30 * 30mm;

After described aspirating hole top fusible link was sealed aspirating hole, the outside surface of fusible link was concordant with the outside surface of sheet glass;

The thickness of described vacuum chamber is 0.3mm.

Advantage and the positively effect that the utlity model has are: seal with fusible link and form the anury vacuum glass, adopt nonmetal upholder, reduced heat-conduction coefficient, 1 kilogram 120 yuan of general nonmetal upholders, screen printing technique location lay, but lay 1000-1200m for each person every day, the productivity height, cost is low.

Fig. 1 is the utility model one-piece construction synoptic diagram.

Among Fig. 1: 1. sheet glass, 2. nonmetal upholder, 3. aspirating hole, 4. fusible link,

5. vacuum chamber, 6. edge sealing.

Embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows, see also Fig. 1.

As shown in Figure 1: adopt nonmetal upholder 2 in the middle of the layer glass plate 1 up and down, the material of described nonmetal upholder 2 is zirconium white or zirconium silicate; It is shaped as ball, ring-type and the column of high 0.3mm, nonmetal upholder 2 adopts screen printing technique to be positioned to square formation formula lay, when simple glass, its spacing is 30 * 30mm, be 0.3mm vacuum chamber 5 in the middle of the layer glass plate 1 up and down, 6mm aspirating hole 3 is opened the place, an angle at monolithic sheet glass 1, and aspirating hole 3 tops are fixed with fusible link 4, fusible link 4 is heated in vacuum oven and is melted and shutoff aspirating hole 3, and makes the outside surface of fusible link 4 concordant with the outside surface of sheet glass 1 or be concave surface.

During use, open aspirating hole 3 at last sheet glass, employing screen printing technique location, close the sheet reversal process with the location and lay the nonmetal upholder 2 that is the square formation formula, last glass sheets 1 is beaten the gradient at the edge sealing place, then, cleaning is closed sheet with cryogenic glass powder edge sealing 5, advances the High Temperature Furnaces Heating Apparatus sintering, and the temperature progress of controlling well guarantees the stress of glass, the cooling back checks whether gas leakage is arranged, have gas leakage from new sintering, then, put vacuum high temperature furnace into and vacuumize, heating after vacuum tightness arrives index allows the glass exhaust, and heating up then after the exhaust again, fusible link 4 melts and shutoff aspirating hole 3.

Its advantage is: seal with fusible link and form the anury vacuum glass, adopt nonmetal upholder, reduced heat-conduction coefficient, 1 kilogram 120 yuan of general nonmetal upholders, screen printing technique location lay, but lay 1000-1200m for each person every day, the productivity height, cost is low.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
