Title:
FIREPROOF GLASS, EVALUATION METHOD AND PRODUCTION METHOD OF FIREPROOF GLASS
Document Type and Number:
Japanese Patent JP2014218422
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fireproof glass excellent in light transmissivity, having thin thickness of a glass plate, and having high intensity of the glass plate.SOLUTION: A glass 101 to which high surface compression stress can be applied even with thin thickness, and which has been subjected to chemical strengthening processing is used as a fireproof glass. the fireproof glass may be formed into a multiple glass formed of a glass laminate and the glass 101 subjected to the chemical strengthening processing, a multiple glass formed of the plural glasses 101 subjected to the chemical strengthening processing, and a multiple glass in which a Low-E layer is formed on the glass plates, thereby the fireproof glass has more thinner thickness and higher intensity. The surface compression stress of the chemical strengthened glass is 180 MPa or more. Depth of the surface compression stress is 1 μm or more, and the plate thickness of the glass is 2-3 mm.
