Description

HIGH THERMO AND SOUND-INSULATING EVACUATED
GLASS PANEL DEVICE
Technical Field
The present invention relates to a high thermo and sound-insulating evacuated glass device, particularly, an evacuated glass device, employing hollow support pillar as support means disposed between two planar glass sheets. The present invention concerns the technical field of glass manufacturing.
Background of the Art
The evacuated glass panel has achieved rapidly development through nearly a hundred year's investigation and research. Both the theoretical study and the scientific practice have proved that the evacuated glass panel is a practical material with good thermo and sound insulating performance, and widely used on doors and windows of building and thermo-shielding and insulating electric apparatus and equipment
The evacuated glass panel includes at least two planar glass sheets and edge seal component. After technologic evacuating the space between two planar glass sheets formed an evacuated glass panel with evacuated lamination. Because of atmospherical pressure effect it is possible to cause opposite adherence of two planar glass sheets of evacuated glass panel, in order to maintain the evacuated layer people always employs support means disposed between two planar glass sheets to resist the compressive deformation due to atmospheric pressure.
At present, people commonly employ most support pillar or support wire net as support means, and commonly employed material is glass, plastic or metal wire and flare. This method of supporting leads to unfavorable influence in two aspects. At first, when a large number of support means, particularly plastic or metal support means is employed, the transmissivity of evacuated glass panel is effected negatively, especially during manufacturing process of doors or windows, said support means may influence the people's line of sight through doors or windows, moreover, plastic support means can slowly release gas, after a period of time the degree of evacuation is greatly reduced, thereby decreasing thermo and sound-insulating performance. Secondly, in order to not influence the people's line of sight, glass material is employed as support means whose bottom area must be made very small. However, this type of small support means can not be used for manufacturing large-size, large-thickness evacuated glass panel. The reason is: when an evacuated glass panel has large thickness of evacuated layer, it means that glass support means must have higher height, nevertheless it is difficult for the high glass support pillar with limited bottom area to stand upright on surface of planar glass sheet, particularly during manufacturing large-size evacuated glass panel, a great deal of support glass pillars need to be placed on the surface of planar glass sheet designed to dispose support means, moreover, the pillars must be uniformly distributed and arranged. Therefore, it is very difficult to dispose support means and ensure it not fall during production process.
In addition, during production of evacuated glass panel, in order to maintain higher evacuated degree of evacuation the periphery of evacuated glass panel must be sealed, while the quality of seal treatment exerts a direct influence on operational performance and service life.
Traditional periphery seal is performed by melting, which places the low melting point glass powder in edge gap between two planar glass sheets Under high temperature it melts and adheres to glass, so the sealing effect is achieved. The disadvantage of this method as follow:
1. The low melting glass powder is directly inserted in periphery gap between planar glass sheets for sealing, so that the effective area of evacuated large is decreased, thereby the volume of evacuated chamber is also decreased. The smaller the volume of evacuated chamber is, the lower the thermo and sound-insulating performance will be.
2. The large amount of low-melting point glass powder leads to large tensile stress near edge of glass, such tensile stress results in reducing the mechanical property of evacuated glass panel at last.
3. Because the low-melting point powder seals and joins two planar surfaces, such sealing method increases the probability of air leak, thereby decreasing the ratio of qualitatively finished evacuated glass panel and it's life.
Summary of the Invention
The main object of the present invention is, regarding to the disadvantages of above-mentioned traditional method of disposing support means within evacuated glass panel, to provide a high thermo and sound-insulating evacuated glass panel device, which employs a hollow pillar as support means disposed between two planar glass sheets, thereby obtaining a higher support height under condition without or with slightly increasing the bottom area of support means, it is suitable for producing large-size evacuated glass panel. The secondary object of the present invention is, regarding to the disadvantages of above-mentioned traditional method of periphery sealing, to provide a high thermo and sound-insulating evacuated glass panel device, said evacuated glass panel device through which the low melting point glass powder melts and joins the edge frame component to periphery of evacuated glass panel, thereby increasing its service life and aesthetic sense.
Said above objects of this invention are realized through following technical schemes:
A kind of high thermo and sound-insulating evacuated glass panel device includs at least two planar glass sheets in any shape and support means disposed there between; the space between said two planar glass sheets is evacuated, a seal component is placed around the periphery of planar glass sheets, characterized in that said support means is a hollow support pillar, said hollow pillar has penetrated portion at its side or top surface for communication of its inner-cavity with the space between planar glass sheets, said hollow pillar is a cylinder or rhomb. Said sealing component has low melting point glass powder applied on its inner side and is used to vertically be sealed and joined to edge frame component around periphery of planar glass sheet. The high thermo and sound-insulating evacuated glass panel device provided by this invention employs a hollow support pillar as support means disposed between planar glass sheets, thus making the support meants far higher than that of traditional ones, neverthless, contacting bottom area of support means and planar glass sheet does not increase or increase slightly increase, said hollow support pillar can be used for manufacturing large-size, high transmissible evacuated glass panel which can't be manufactured by traditional support means. During production process of evacuated glass panel, because hollow support pillar with wide bottom area is more easy to be placed on the surface of planar glass sheets in comparison with solid support means of same height. It's not easy to turn down in transportation of manufacturing evacuated glass panel, so that the practice operation is convenient and the operation effect is increased.
In addition, the high thermo and sound-insulating evacuated glass panel device provided by this invention employs low melting glass powder to melt and join the edge frame component to periphery of evacuated glass panel, no matter whether glass strip or metal frame is employed as edge frame component, because the sealing and joining surface is not planar, the edge frame has a right angle in contract to the surface of planar glass sheet, so the probability of air leak is greatly reduced, thereby leading to good sealing effect and increasing the ratio of qualitative finished evacuated glass panel and service life. The evacuated glass panel employing edge frame component for sealing has obviously decreased tensile stress around it's periphery and greatly increased mechanical strength. Because the sealing and joining surface is not planar, and the lateral surface of planar glass sheet is employed as sealing and joining surface, so the effective area of evacuated glass panel is increased, thereby enlarging the volume of evacuated chamber and improving its operation performance. When the evacuated glass panel employs metal frame as a edge frame component, the metal frame makes the edge of sealed evacuated glass panel have higher mechanical strength. Moreover, the employing metal frame for sealing eliminates the need for additional outer frame, thereby reducing the cost of re-processing evacuated glass panel at later manufacturing stage.
