  • the vacuum glass according to the present invention does not lose its function even when the functional sheet glass of soft type low-E glass, electrochromatic glass, reflecting glass, or glass on which a solar cell substrate is formed is applied.
  • the sheet metal having the shape of easy expansion and contraction is absorbed by the metal sheet so that the deflection and cracking do not occur. This increases the durability and has the effect of extending stability and lifespan, and there is no need to perform a separate exhaust process, and thus forming the exhaust hole and the exhaust tube or forming the exhaust tube, thereby simplifying and facilitating the process. .
  • the vacuum glass according to the present invention increases durability, can be used in various fields, and can be said to be an effective invention in general use.

Abstract

L'invention concerne un procédé de production de verre sous vide qui produit un verre sous vide par superposition d'une pluralité de vitrages de telle sorte que des espaces sous vide se forment entre les vitrages, et un verre sous vide produit au moyen dudit procédé. L'invention concerne plus particulièrement, une plaque métallique mince pouvant s'étendre et se rétracter qui est introduite pendant la liaison hermétique de la pluralité de vitrages au moyen de verre en poudre à point de fusion bas, de sorte qu'aucune contrainte n'est générée même sur les vitrages disposés aux deux extrémités de la pluralité de vitrages de verre sous vide lorsque ces derniers se rétractent et s'étendent de manières différentes suite à une différence de température entre les deux extrémités des vitrages. Même si la température varie grandement à l'intérieur du verre sous vide, la plaque métallique mince absorbe la contrainte entraînée par la rétraction et l'extension aux deux extrémités du verre sous vide, et empêche la génération d'une déflexion et de fissures dans le verre sous vide. Lors de l'exécution d'une liaison hermétique de verre à point de fusion bas dans une atmosphère sous vide élevé, le verre sous vide ne perd pas sa fonctionnalité même si des vitrages fonctionnels du type de ceux qui perdent leur fonctionnalité suite à une oxydation, tels qu'un verre tendre à faible émissivité, un verre réfléchissant, un verre électrochrome ou un verre à substrat de cellule solaire, sont utilisés.
