Abstract

(A) A process for producing a sealed joint between a glass surface and a metallic material involves metal coating of the glass surface by a plasma process. (B) A heat insulating construction and/or lighting element consists of two or more parallel wall elements having interposed support elements and forming an evacuatable interspace with a sealed joint at the edge region. The novelty is that the interspace is formed by a gap between the wall elements which is less than the free path length of gas molecules in the fine vacuum range of 1-10 power(-3) mbar required for cancelling heat conduction. Relative displacement of the wall elements in the edge region is absorbed by a seal. (C) A process and an appts. for prodn. of the construction and/or lighting element are also claimed.

   BESCHREIBUNGEN



   An die Randabdichtungen von Isolierglasscheiben, bei denen sich zwischen zwei Gläsern ein Hohlraum mit trokkener Luft oder einem Isolierglas befindet, werden hohe Anforderungen an die Dichtheit gestellt. Es ist bekannt, solche Randabdichtungen aus einem Metallband, mit einer Legierung herzustellen, welche ähnliche Ausdehnungseigenschaften wie Glas besitzt.



   Solche Metallbänder werden durch ein Schmelzlot mit dem Glas, bzw. einer Kupferschicht, dichtend verschmolzen.



  Damit das Schmelzlot mit dem Glas eine Verbindung eingehen kann, wird die Glasoberfläche am Glasscheibenrand mit einer dünnen Kupferschicht überzogen. Der Auftrag der dünnen Kupferschicht wird durch das sog. Flammspritzen erreicht. In der Flamme eines Azetylen-Sauerstoffbrenners wird ein Kupferdraht nachgeführt und abgeschmolzen.



   Die geschmolzenen Kupferteilchen werden durch die heisse Flamme auf die Glasoberfläche gespritzt und verschmelzen mit der Glasoberfläche. Das grosse Problem des Flammspritzens besteht in der Oxydation des flüssigen   Kuj >     fers in der Gasflamme, die mit Sauerstoff und Azetylengas gespiesen wird. Der geringste Sauerstoffüberschuss in der Gasflamme verursacht eine Oxydation des flüssigen Kupfers, was eine sichere und dichtende Verbindung mit der Glasoberfläche fragwürdig macht.



   Schlechthaftende Kupferschichten führen zu undichten Glasrandabdichtungen und damit zu aufwendigen Garantiearbeiten. Um dies zu verhindern, wird vorgeschlagen, ein Metallspritzverfahren anzuwenden, welches die Nachteile des Azetylen-Sauerstoff-Flammspritzens nicht mehr aufweist.



   Besonders für vakuumisoliertes Fensterglas werden sehr hohe Anforderungen an die Dichtheit des Randverbundes gestellt.



   Das Plasmaauftragverfahren, für die Isolierglasfabrikation noch nie angewandt, kann den gestellten Anforderungen genügen. Eine Oxydation des verflüssigten Metalls ist völlig ausgeschlossen, weil der Metallschmelzprozess in einem Edelgasmedium stattfindet. Daraus resultieren gut reproduzierbare, homogene und oxydfreie Metallschichten auf Glasscheiben.



   Beim Plasmaverfahren wird das Edelgas, wie z.B. Argon, einem Brenner zugeführt und durchströmt in diesem einen elektrischen Lichtbogen. Das Edelgas   wirdionisiert,    wobei sich ein Elektron abspaltet und einen grossen Energiestoss erzeugt. Ein zweiter Energiestoss entsteht dadurch, dass das abgespaltete Elektron wieder zurückfällt. Dem jonisierten Gas, welches Temperaturen von ca. 20   ooot    erreicht, wird dosiert das Material in Pulverform zugegeben, welches auf die Glasoberfläche aufgetragen werden soll, z.B. Kupfer. Die flüssigen Kupferteilchen werden mit hoher Geschwindigkeit auf die Glasoberfläche geschleudert, und verschmelzen mit dem Glas innerhalb eines Edelgas-Schutzmantels unter Sauerstoffausschluss.



   Damit auch die Glasoberfläche frei ist von Wasser- und Sauerstoff wird diese vorteilhaft unmittelbar vor dem Aufspritzen der Metallschicht mittelst eines heissen Schutzgasstrahls oder einer Flamme gereinigt, wobei die Flamme auch mit einem Plasma-Brenner erzeugt werden kann.



   Da die mit dem metallischen Werkstoff z.B. Kupfer beschichtete Glasoberfläche den Zweck hat, das Glas dichtend mit einer metallischen Randabdichtung bei einem Vakuumisolierglasfenster mit einem Schmelzlot zu verbinden, kann vorteilhaft unmittelbar nach dem Kupferauftrag eine Lotschicht ebenfalls mit dem Plasmaverfahren aufgetragen werden. 



  
 



   DESCRIPTIONS



   The edge seals of insulating glass panes, where there is a cavity with dry air or an insulating glass between two glasses, place high demands on the tightness. It is known to produce such edge seals from a metal band with an alloy which has similar expansion properties to glass.



   Such metal strips are sealed to the glass, or a copper layer, in a sealed manner by a solder.



  So that the fusible link can form a connection with the glass, the glass surface is coated with a thin copper layer on the edge of the glass pane. The thin copper layer is applied by so-called flame spraying. A copper wire is fed into the flame of an acetylene oxygen burner and melted down.



   The molten copper particles are sprayed onto the glass surface by the hot flame and fuse with the glass surface. The big problem with flame spraying is the oxidation of the liquid gas in the gas flame, which is fed with oxygen and acetylene gas. The slightest excess of oxygen in the gas flame causes an oxidation of the liquid copper, which makes a secure and sealing connection with the glass surface questionable.



   Badly adhering copper layers lead to leaky glass edge seals and thus to expensive warranty work. To prevent this, it is proposed to use a metal spraying method which no longer has the disadvantages of acetylene-oxygen flame spraying.



   Particularly for vacuum-insulated window glass, there are very high demands on the tightness of the edge bond.



   The plasma application process, which has never been used for insulating glass production, can meet the requirements. Oxidation of the liquefied metal is completely ruled out because the metal melting process takes place in an inert gas medium. This results in easily reproducible, homogeneous and oxide-free metal layers on glass panes.



   In the plasma process, the noble gas, e.g. Argon, fed to a burner and flows through an electric arc in it. The noble gas is ionized, whereby an electron splits off and generates a large energy surge. A second energy surge results from the fact that the split-off electron falls back. The ionized gas, which reaches temperatures of approx. 20 ooot, is metered with the material in powder form which is to be applied to the glass surface, e.g. Copper. The liquid copper particles are thrown onto the glass surface at high speed, and fuse with the glass within an inert gas protective jacket with the exclusion of oxygen.



   So that the glass surface is also free of water and oxygen, it is advantageously cleaned immediately before the metal layer is sprayed on by means of a hot protective gas jet or a flame, the flame also being able to be generated using a plasma burner.



   Since the metal material e.g. Copper-coated glass surface has the purpose of sealingly connecting the glass with a metallic edge seal in a vacuum insulating glass window with a solder, a solder layer can advantageously also be applied directly after the copper application using the plasma process.
