Description
Verbundglas wird bekanntlich derart hergestellt, daß zwischen zwei Glasplatten eine unzerbrechliche und durchsichtige Verstärkungsschicht aus anderem Stoff eingelegt und mit den Glasplatten verbunden wird.Laminated glass is known to be produced in such a way that one between two glass plates unbreakable and transparent reinforcement layer made of another material and inserted is connected to the glass plates.
Bei den bekannten Herstellungsverfahren dieser Art werden vielfach Glasplatten verwendet, deren innere, an der Zwischenlage anliegende Flächen unbearbeitet sind. DieseIn the known manufacturing processes of this type, glass plates are often used, the inner surfaces of which are in contact with the intermediate layer are unprocessed. These
»ο Flächen sind jedoch nicht vollkommen eben; infolgedessen entstehen durch die Verbindung der Glasplatten mit der Zwischenlage Spannungen, welche die Haltbarkeit des Glases beeinträchtigen und vielfach Aufspalten des»Ο Surfaces, however, are not perfectly flat; as a result, the connection of the glass plates with the intermediate layer creates tension, which affect the durability of the glass and often split the
«5 Glases oder Bruch zur Folge haben.«5 glass or breakage.
Bei anderen Verfahren werden Glasplatten verwendet, deren innere, der Zwischenlage anliegende Flächen durch Grob-, Feinschleifen und Polieren vorher eben gemacht werden.In other methods, glass plates are used, the inner layer of which lies against the intermediate layer Surfaces are made level beforehand by coarse, fine sanding and polishing.
so Dadurch, daß die so bearbeiteten Flächen ebener sind als unbearbeitete Flächen, vermeiden sie das Entstehen von Spannungen; aber der Preis .des Verbundglases ist entsprechend höher.so that the so machined surfaces are more even than unprocessed surfaces, they avoid the development of tension; but the price of the laminated glass is correspondingly higher.
«5 Das Verfahren nach der Erfindung schaltet die Nachteile dieser bekannten Verfahren aus. Frfindungsgemäß werden die an der Zwischenlage anliegenden Flächen der Glasplatten nur durch Grobschleifen und Feinschleifen eben gemacht. Die kleinen Unebenheiten der so bearbeiteten Flächen sind nach der Verbindung der Platten mit der Zwischenlage nicht sichtbar, weil die Zwischenlage ganz oder wenigstens an der Oberfläche nahezu den gleichen Brechungsindex und das gleiche Lichtstreuungsvermögen wie das Glas besitzt.«5 The method according to the invention switches the disadvantages of this known method. According to the invention, those on the intermediate layer adjacent surfaces of the glass plates can only be leveled by rough grinding and fine grinding made. The small unevenness of the surfaces machined in this way are after the connection of the plates with the intermediate layer not visible, because the intermediate layer is entirely or at least almost the same refractive index and the same light scattering power on the surface like the glass owns.
Dieses Verfahren hat gegenüber den bekannten Verfahren folgende Vorteile:This method has the following advantages over the known methods:
1. Die feingeschliffenen Flächen sind praktisch genau so eben wie die auf der Maschine polierten Flächen; der Preis des so hergestellten Verbundglases ist geringer als der Preis des aus poliertem Glas hergestellten Verbundglases.1. The finely ground surfaces are practically exactly as flat as those on the machine polished surfaces; the price of the laminated glass produced in this way is lower than that Price of laminated glass made of polished glass.
2. Die Glasscheiben haften wesentlich fester an der Zwischenlage, wenn die Innenseiten der Glasscheiben feingeschliffen sind, als wenn sie poliert sind. Infolgedessen wird durch die Erfindung das Loslösen der Schichten des Verbundglases, welches oft nach einiger Zeit eintritt, besonders bei nicht ganz ebenen Glasplatten, vollkommen vermieden. .2. The panes of glass adhere much more firmly to the intermediate layer when the inside the panes of glass are honed as if they were polished. As a result, will by the invention the detachment of the layers of the laminated glass, which often after This is completely avoided for some time, especially with glass plates that are not completely flat. .
3. Das nach der Erfindung hergestellte Verbundglas kann an den Außenflächen ohne die Gefahr der Zerstörung und Beschädigung bearbeitet, also beispielsweise grob- und feingeschliffen, poliert, mit schrägen Kanten oder Löchern versehen werden. Werden diese Arbeiten an den einzelnen Glasplatten vor ihrer Verbindung vorgenommen, so ist in- 6a3. The laminated glass produced according to the invention can on the outer surfaces without the Risk of destruction and damage machined, for example coarsely and finely ground, polished, with beveled edges or Holes are provided. If this work is carried out on the individual glass plates before they are connected, then 6a
folge der geringen Stärke der Platten die GeTahr des Zerbrechens oder der Beschädigung wesentlich größer.Due to the thinness of the panels, there is a risk of breakage or damage much bigger.
