METHOD FOR PRODUCING DOUBLE-LAYERED GLASS
PROBLEM TO BE SOLVED: To provide a method for producing a double-layered glass capable of suppressing the deflection amount of a glass plate caused by a change in the outer atmospheric pressure, and also, capable of preventing the leakage of a functional gas sealed into a hollow layer.SOLUTION: In the first altitude region, two glass plates 12, 12 are separated by a spacer 14 to laminate them via a hollow layer 16. After that, the edge parts of the two glass plates 12, 12 are adhered with the primary seal material 18 and secondary seal material 20 as seal materials to close the hollow layer 16. Subsequently, the production method includes a pressure reduction step where the pressure of the hollow layer 16 is reduction-adjusted in the first altitude region, and in such a manner that, in the second altitude region having an altitude higher than that of the first altitude region and to be set with a double-layered glass 10, provided that the deflection amount of the two glass plates 12, 12 in the second altitude region of the double-layered glass produced without being subjected to the pressure reduction are defined as the first deflection amount, the deflection amount of the two glass plates 12, 12 in the second altitude region reaches the second deflection amount smaller than the first deflection amount, the two glass plates 12, 12 are deflected at the third deflection amount in the pressure reduction step.SELECTED DRAWING: Figure 2
【課題】外気圧の変化に起因するガラス板の撓み量を抑制することができ、かつ中空層に封入された機能性ガスの漏出を防止することができる複層ガラスの製造方法を提供する。【解決手段】第１標高地帯において、２枚のガラス板１２、１２をスペーサ１４によって隔置することにより中空層１６を介して積層する。この後、２枚のガラス板１２、１２の端縁部をシール材である一次シール材１８と二次シール材２０とで接着することにより中空層１６を密閉する。この後、第１標高地帯にて中空層１６の圧力を減圧調整する減圧工程を有し、第１標高地帯よりも標高が高く複層ガラス１０が設置される第２標高地帯であって、減圧工程を経ずに製造された複層ガラスの第２標高地帯における２枚のガラス板１２、１２の撓み量を第１撓み量としたときに、第２標高地帯における２枚のガラス板１２、１２の撓み量が、第１撓み量よりも小さい第２撓み量となるように、減圧工程において、２枚のガラス板１２、１２を第３撓み量で撓ませる。【選択図】図２
