Description

Vacuum flat glass

The utility model relates to a kind of vacuum flat glass, belongs to building material technical field.

In modern building, it is very big seeing through the lost heat energy of door and window, especially at cold district, according to the statistics of Sweden, can reach 8%, and the heat-insulating property of therefore improving glass window also is very important.

Existing hollow sheet glass structure generally adopts double-layer glass, uses encapsulant and metal framework sealing and fixing on every side, fill between glass with air or inert gas, and add getter, its major defect is not to be vacuum between the glass plate, the heat transfer of gas still exists, and makes insulation effect unsatisfactory, secondly, in order to reduce the conduction of heat of gas, between glass bigger spacing should be arranged, make integrally-built thickness, volume all increases, and use encapsulant and metal framework, also increased cost.

Be evacuated between double-layer glass as patent 9310105447.8 (CN1094475A) in addition, and cylindrical support is set, supporter is made with glass or plastics, its shortcoming is the supporter venting, can not keep vacuum, therefore, heat-insulating property is relatively poor, and this supporter can not bear atmospheric pressure.

The purpose of this utility model is that a kind of vacuum flat glass will be provided, it can overcome above-mentioned shortcoming, mainly between two blocks of glass, supporter is arranged, the edge of glass does slope-shaped or arc, recharge the glass dust sealant, heat sealing, or process a little angle in edge, wherein place glass tube, be convenient to be evacuated.

The purpose of this utility model is achieved in that

A kind of vacuum flat glass, between its two blocks of sheet glass (1) supporter (2) is arranged, between supporter (2) surface and sheet glass (1), one deck transition zone (3) is arranged, a slope (8) or circular arc (8 ') are worn in the edge of a glass in two blocks of sheet glass (1), refill the sealant (9) with glass dust.

At sheet glass 91) edge has a circular hole (10), inserts glass tube (11) in the hole, be coated with on every side with glass dust sealant (9).

The edge of a glass in two blocks of sheet glass (1) is cut into an oblique angle (12), and a semicircle or arc glass pipe (13) are set between oblique angle (12) and another piece glass.

Supporter (2) is flat ellipse (2-1) or cydariform (2-2).

Supporter (2) is netted (2-3) or strip (2-4), honeycombed (2-5).

Supporter (2) be do not connect around cross (3-6) or annular (2-7).

Glass scribbles one deck tin ash, indium oxide film on (1).

The transition zone (3) on supporter (2) surface is the coating of spraying aluminium, silver, nickel, copper.

Now in conjunction with the accompanying drawings the structure structure of vacuum flat glass is described in detail:

By Fig. 1, one deck sealant (9) is arranged between two blocks of sheet glass (1), be equipped with supporter (2) between glass (1), this supporter (2) is made by pottery, metal or alloy material, be used for support glass, improve its compressive strength, it is tin ash or indium oxide that sheet glass (1) is gone up plated film.

By Fig. 2, between supporter (2) surface and glass (1), one deck transition zone (3) is arranged, also be to form one deck hair side after handling with caustic solution, and can cushion support (3) during glass contact and glass (1) between shear stress (9), transition zone also may be the coating of aluminium, silver, nickel, copper.

By Fig. 3 A, supporter (3) is flat ellipse (2-1).

By Fig. 3 B, supporter (3) is cydariform (2-2).

These two kinds of shapes, its two ends are tapers, can keep level, increase contact area, and supporter (3) is consistent highly.

By Fig. 3 C, D, E supporter is netted (3-3), or strip (3-4) or honeycombed (3-5), can improve compressive strength.

By Fig. 3 F, supporter (3-6) is discontinuous cross (2-6), can improve the light transmittance of glass.

By Fig. 3 G, supporter (2-7) is the annular of open-ended.

By Fig. 4 supporter (2) is arranged between two blocks of sheet glass (1), and the edge of glass (1), position as shown by arrows, be the hot melt glass powder seal sealant (9).

By Fig. 5, wear into a slope (8) at a glass edge place of two blocks of sheet glass (1), the slit between the sheet glass (1) (having only usually about 200 microns), filling glass dust sealant (9) in the slit then is by heat sealing.

By Fig. 6 A, B, wear into slope (8) or arc (8 ') at the edge of two blocks of sheet glass (1), be coated with again with glass dust sealant (9), in addition heat sealing.

By Fig. 7, directly glass dust (9) filling is squeezed in the slit, advantage is that operation is few, material-saving again, glass edge does not need milled processed.

By Fig. 8, at sheet glass 91) edge process a circular hole (10), insert glass tube (11) in the hole, be coated with glass dust sealant (9), vacuum heat sealing then around it.

By Fig. 9, edge at a glass of two blocks of sheet glass (1) is cut an oblique angle (12), between oblique angle (12) and another piece glass (1), a semicircle or arc glass pipe (13) are set, the port of glass tube (13) should keep aliging with the plane, oblique angle, this can prevent to infiltrate glass dust, influences its vacuum.

Compared with prior art, vacuum flat glass has following advantages:

1, the thickness of vacuum flat glass is littler, can reach 6 millimeters;

2, adopt glass-dead seal, the vacuum height, no aqueous vapor can the dewfall frosting;

3, the hot will rate of vacuum flat glass is minimum, lacks more than 6 times than single-glass;

4, in light weight, volume is little;

5, do not need metal framework, the door window frame of can directly packing into;

6, technology is simple, and cost is low.
