(EN) THERMALLY STRENGTHENED PHOTOCHROMIC GLASS AND RELATED SYSTEMS AND METHODS
(FR) VERRE PHOTOCHROMIQUE THERMIQUEMENT RENFORCÉ ET SYSTÈMES ET PROCÉDÉS ASSOCIÉS
Abstract
(EN)
A strengthened photochromic glass sheet or article as well as processes and systems for making the strengthened photochromic glass sheet or article is provided. The process comprises heating the photochromic glass sheet to a desired temperature in a short time period without distortion to the photochromic glass sheet. The process also comprises in cooling the photochromic glass sheet by non-contact thermal conduction for sufficiently long to fix a surface compression and central tension of the sheet. The process results in thermally strengthened photochromic glass sheets.

L’invention concerne une feuille ou un article de verre photochromique renforcé(e) ainsi que des procédés et des systèmes de fabrication de la feuille ou de l’article de verre photochromique renforcé(e). Le procédé consiste à chauffer la feuille de verre photochromique à une température désirée en une courte période de temps sans distorsion à la feuille de verre photochromique. le procédé consiste également à refroidir la feuille de verre photochromique par conduction thermique sans contact suffisamment longue pour fixer une compression de surface et une tension centrale de la feuille. Le procédé permet d'obtenir des feuilles de verre photochromiques thermiquement renforcées.
