To maintain high bonding performance between two glass sheets by metal material, thereby to obtain high gas tightness and bonding strength. A glass panel includes a pair of glass sheets (1A, 1B) disposed in opposition to each other with forming a gap (V) therebetween, the peripheral edges of the opposed glass sheets (1A, 1B) being directly bonded to each other by metal material (5); wherein bonding faces (1Aa) in the opposed surfaces of the glass sheets (1A, 1B) to be bonded to the metal material (5) are worked so as to obtain an average surface roughness below 30 nm.

A vacuum insulating glass (IG) unit. In certain embodiments, the internal cavity is evacuated (i.e., pumped out) via a pump-out aperture. A cover with one or more sealing element(s) may be provided over the pump-out aperture so that during the pump-out process air flows out of the internal cavity and through space(s) between adjacent sealing elements or sealing element portions. Following evacuation or pumping out, the sealing element(s) is/are heated and the sealing member may be pressed downwardly toward the substrate. This causes the heat-softened sealing element(s) to expand horizontally and merge with one another so as to form a hermetic seal around the pump-out aperture and between the sealing member and the substrate.

There is provided a method of manufacturing a glass panel and the glass panel manufactured by the method, which makes it possible to minimize the projection amount from the glass sheet surface for improved appearance and for reduced possibility of breaking-up of the depressurized condition resulting from contact with an object and also to reliably seal the vent with a relatively easy step. A number of spacers (2) are disposed between a pair of glass sheets (1A, 1B). Outer peripheries of the glass sheets (1A, 1B) are sealed with an outer periphery sealing portion (3) to form a gap (V) between the glass sheets (1A, 1B). A vent (4) is formed in one (1A) of the glass sheets (1A, 1B) for evacuating gas from the gap (V). The gas in the gap (V) is evacuated via the vent (4) to depressurize the gap (V), and then the vent (4) is sealed. A metal solder (6) is employed as a sealing material for sealing the vent (4). A piece (6A) of the metal solder is heated and molten adjacent the vent (4) to break open an oxide skin (6a) on the surface of the metal solder (6), so that the metal solder (6) therein is allowed to flow out through the broken oxide skin to come into contact directly with the one glass sheet (1A), whereby the metal solder (6) is cooled and solidified by the contact, thus sealing the vent (4).
摘要:
A method of manufacturing heat-insulating structural and/or light elements composed of at least two wall elements of glass, a glass alloy or metal, wherein the wall elements are separated from each other by support elements and are provided on at least one of surfaces thereof facing each other with a layer reflecting heat radiation, and wherein the structural and/or light elements further are composed of a deformable sealing element for connecting the wall elements to obtain a hollow space between the wall elements which can be evacuated or supplied with gas. The method includes conveying wall elements which have been cleaned and coated on at least one surface thereof and are intended for a structural and/or light element in a manufacturing line extending over manufacturing sections, coating with solder at least one side of each wall element at edges thereof, placing spaced-apart support elements on a wall element, positioning the wall elements opposite each other at a distance determined by the support elements, and subsequently enclosing the wall elements to form a gas-tight hollow space between the wall elements by applying a deformable metal sealing element at the coated edges of both wall elements.
摘要:
A method of constructing a glass panel which comprises two confronting edge sealed glass sheets, the method comprises the steps of providing a solder glass band around the margin of one surface of each glass sheet, forming, at a first temperature, an hermetic bond between the solder glass band and the associated surface of each glass sheet, positioning the glass sheets in spaced-apart confronting relationship, forming, at a second temperature which is lower than the first temperature, an hermetic seal between the two solder glass bands whilst maintaining the spaced apart relationship between the glass sheets.
摘要:
A method of producing a vacuum between two glass sheets to form an insulating glazing. One of the sheets has a hole drilled in its thickness. Spacers are placed between the two glass sheets with the sealing joint being placed around the periphery of the sheets. A vacuum is created between the sheets through the hole which is then closed. The spacers are fixed on one of the sheets by bonding with a mineral compound covering at least the bonding zones on the glass sheet. The second sheet is placed on the spacers and on the peripheral sealing joint. The peripheral sealing and the bonding with the spacers are simultaneously effected by raising the temperature.

A vacuum insulating glass (IG) unit and method of making the same. An edge seal of the vacuum IG unit includes at least one fiber (e.g. elongated glass fiber) provided at least partially between first and second opposing substrates in order to hermetically seal off a low pressure space between the substrates. A plurality of spacers are located between the substrates to space the substrates from one another and maintain the low pressure space therebetween.

A glazed element having a high insulating ability is composed of at least two glass sheets, between which a vacuum has been created, separated from each other by mounts distributed over their entire surface. The sheets are joined together around their periphery by an inorganic seal. The glazed element has at least one hole scaled in a vacuum-tight manner around its periphery with the aid of an inorganic seal.
摘要:
This invention relates to double glazing having two glass sheets with numerous spacers arranged therebetween, a void therebetween being sealed in a decompressed condition. Conventionally, the glass sheets have edges thereof spaced from each other by a seal. Under the influence of the binding force of the seal atmospheric pressure tends to act less on outermost spacers than on the other spacers. Consequently, the outermost spacers tend to move between the glass sheets. According to this invention, an outer interval (L1) between each outermost row of spacers (2) and a seal (4) is set at least equal to a basic interval (L0) between the outermost row and a second row adjacent thereto. Consequently, the spacers in the outermost rows bear a larger share of atmospheric pressure acting on the sheet surfaces than the spacers in the other rows. A sufficient force is secured to hold the spacers in the outermost rows in place, thereby preventing the spacers in the outermost rows from moving between the two glass sheets.
摘要:
Vacuum glazings and methods of manufacture thereof are described; the glazings provide improved shear stress resistance in that the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating internal vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the pillars (5) consist of a core (13), made of a material of higher compressive strength, with at least one end covered by a layer of softer material (14). Alternatively, the vacuum glazing comprises two sheets of glass (2, 3), hermetically sealed around the edge (4), with a thermally insulating vacuum, and an array of support pillars (5) placed between the glass sheets (2, 3), wherein the array includes a small number of fused solder glass pillars located over the surface of the glazing, between pillars of higher compressive strength. Advantageously the support pillars (5) comprise two flat parallel ends (15, 16) shaped to provide stable equilibrium, and sides (17) shaped to provide unstable equilibrium, to ensure that the pillars when placed on a glass sheet will fall onto one of the flat faces (15, 16) and thereafter lie on that face.
