Abstract

A getter setting device for vacuum chamber of high heat insulation and high sound insulation vacuum glass comprises glass plates supported by a pillar. The circumference of the glass plate is sealed with vacuum space among the glass plates. The inner surfaces of the upper and the lower glass plates are provided with a groove at the same time and the groove is provided with the getter that is sintered by the low melting point glass powder on the glass plates. By adopting the device, the utility model can fairly improve vacuum degree and has radio protective function; cracks are not easy to take place around the groove; the utility model does not have great effect on the glass and the yield is high.

Description

The vacuum chamber getter setting device of high heat insulation, high sound insulation vacuum glass

Technical field

The utility model relates to a kind of vacuum flat glass getter setting device, is meant the vacuum chamber getter setting device of thin high heat insulation, high sound insulation vacuum glass especially, belongs to glass manufacturing area.

Background technology

Vacuum glass is that the space that will connect between the sealed glass plate all around is evacuated, to reach purpose heat insulation, sound insulation.Because the gap between glass plate is very little, can bear the effect of atmospheric pressure for making glass plate under vacuum state, is placed with pillar between glass plate.Pillar is very little, and naked eyes can't be seen generally speaking, not influence functional performance.

Vacuum glass has been obtained very big progress through the research and development of last 100 years, theoretical research and measuring to vacuum glass are verified, vacuum glass is desirable heat insulation, sound insulation materials, can do the door and window of building, also can be used to be incubated cabinet, refrigerator or refrigerator.Need aspect many to improve but on industrial production, also have, for example, the getter setting device of vacuum chamber.

The main component of getter is zirconium (Zirconium) aluminium (Alumnium) alloy (84% zirconium and 16% aluminium), be processed into powdery granule, be compressed on the metallic substrates, by heating, it is at high temperature evapotranspired, there is the strong adsorption effect at the fresh interface that forms to the residual gas of leaving in the vacuum, can improve the vacuum of vacuum glass, and can radioresistance.

But the placement getter normally is difficult to realize in vacuum chamber, and its reason mainly is:

1, vacuum gap is too little, fails to lay down getter;

2, if groove of processing is used for placing getter on sheet glass, the groove periphery easily produces micro-crack, and stress is concentrated, and micro-crack enlarges when getter high temperature heats, and can cause glass breakage.

The utility model content

Main purpose of the present utility model is to provide a kind of vacuum chamber getter setting device of high heat insulation, high sound insulation vacuum glass, by the residual gas in the getter absorption vacuum glass, and improving its vacuum, and can radioresistance.

Another purpose of the present utility model is to provide a kind of vacuum chamber getter setting device of high heat insulation, high sound insulation vacuum glass, produces micro-crack, yield rate height around the glass that can avoid getter to adhere to.

The purpose of this utility model is achieved by the following technical solution:

Upper and lower layer glass plate inner surface at vacuum glass has set a groove simultaneously, is placed with getter in the groove, is provided with separation layer between groove and getter.

Described separation layer is a glass powder with low melting point, and getter by its sintering on glass plate.

The utility model can reach following effect:

1, vacuum is further improved, convection current thermal conductance effect drops to minimum point;

2, the extremely thin visual effect that do not influence of the rete that evapotranspires, but infrared rays is had stronger reflection, effectively reduced the radiation thermal conductance;

3, the raising work efficiency that cuts down the consumption of energy needn't be to the baking of heating for a long time of vacuum glass integral body;

4, since getter by the low-melting glass powder sintering on the glass groove, the thermal conductivity ratio glass of glass powder with low melting point is much lower, the transient heating getter just can not produce a very large impact glass, has improved yield rate greatly.

5, owing to be to have set a groove simultaneously at levels glass plate inner surface, so the degree of depth of groove just needn't be too dark, and the mechanical strength of vacuum glass integral body is greatly improved.

Description of drawings

Fig. 1 is high heat insulation, a high sound insulation vacuum glass schematic cross-section of placing getter in the utility model groove.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

As shown in Figure 1, set a groove 2 simultaneously, in groove, placed getter 3, improved the vacuum and the capability of resistance to radiation of vacuum glass at the upper and lower layer of glass plate inner surface; Offer groove simultaneously and also avoided too little, fail to lay down the difficulty of getter owing to the vacuum chamber gap; Be provided with glass powder with low melting point 4 between groove and getter, on glass plate, because the thermal conductivity ratio glass of glass powder with low melting point is much lower, the transient heating getter can not be a glass breakage just to getter, thereby has improved the yield rate of vacuum glass by its sintering.

It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
