It is a figure which shows the example of the setting conditions of a process.
- the temperature reached by the melting furnace is set to a temperature higher than the softening point temperature 434 ° C. of the glass frit used in the frit seal 4 and the partition walls 5a, 6a, 7a. As 450 ° C. At this time, the frit seal 4 starts to melt, the peripheral portions of the pair of glass sheets 1 and 2 are sealed, and a sealable space 3 is formed between the pair of glass sheets 1 and 2.

- the furnace temperature in the first melting step is equal to the softening point temperature of the glass frit. Since the temperature is set to 450 ° C., which is slightly higher, the partition walls 5a, 6a, and 7a are not greatly deformed, and the slits 5b, 6b, and 7b formed in the partition walls 5a, 6a, and 7a are not blocked. It becomes a state. In the first melting step, it is important that the slits 5b, 6b, 7b formed in the partition walls 5a, 6a, 7a are not blocked, so that the maximum temperature of 450 ° C. in the first melting step is maintained.

- the plate glass can be cut by a water jet method or a laser cut method in addition to a method using a glass cutter.
- the water jet method or the laser cut method is used in order to reliably cut the plate glass. Is more preferred in many cases.
- FIG. 6 shows a state where the partial areas A, B, and C are cut along the broken line 11 shown in FIG.

Claims (11)
- 所定間隔を隔てて対向配置された一対の板ガラスの周辺部を封着材で封着して前記板ガラスの間に密閉可能な空間を形成し、排気口から排気することによって前記空間内を減圧状態とした後、
前記空間内に配置された領域形成材によって前記空間を分割して前記排気口が含まれない部分領域を形成し、
その後前記一対の板ガラスを切断して前記部分領域を切り出すことを特徴とする複層ガラスの製造方法。 - 前記領域形成材は、前記空間が形成された状態で前記部分領域の内外を接続する通気部を有し、前記空間内を減圧状態とした後に前記通気部が閉塞されて前記空間を分割して前記部分領域を形成する請求項1に記載の複層ガラスの製造方法。
- 前記通気部が、断続的に形成された前記領域形成材の不連続部分であり、前記空間内を減圧状態とした後に前記領域形成材を溶融させて前記不連続部分を連続させる請求項2に記載の複層ガラスの製造方法。
- 溶融前の前記領域形成材の形成高さを、溶融前の前記封着材の形成高さよりも低く形成し、
前記封着材が溶融して前記一対の板ガラスが封着された状態で前記空間内を減圧状態とし、その後前記一対の板ガラスの間隔を狭くして前記領域形成材によって前記空間を分割して前記部分領域を形成する請求項1に記載の複層ガラスの製造方法。 - 前記領域形成材の溶融温度が前記封着材の溶融温度よりも高く、前記封着材が溶融する温度で前記一対の板ガラスを封着して前記空間を形成し、前記空間内を減圧状態とした後に、前記領域形成材が溶融する温度で前記領域形成材を溶融させて前記空間を分割して前記部分領域を形成する請求項1~4のいずれかに記載の複層ガラスの製造方法。
- 溶融炉内において前記封着材を溶融させて前記空間を形成した後、前記溶融炉から取り出して前記空間を減圧状態とした後、再び溶融炉内において前記領域形成材を溶融させて前記空間を分割して前記部分領域を形成する請求項1~5のいずれかに記載の複層ガラスの製造方法。
- 前記排気口が、前記一対の板ガラスの少なくともいずれか一方に形成されている請求項1~6のいずれかに記載の複層ガラスの製造方法。
- 前記封着材および前記領域形成材がガラスフリットである請求項1~7のいずれかに記載の複層ガラスの製造方法。
- 前記一対の板ガラスのいずれか一方の表面に、前記一対の板ガラスの間隙を規定するスペーサーが配置されている請求項1~8のいずれかに記載の複層ガラスの製造方法。
- 前記封着材形成部分に、前記一対の板ガラスの間隙を規定する高さ規制部材が配置されている請求項1~9のいずれかに記載の複層ガラスの製造方法。
- 前記スペーサーまたは前記高さ規制部材の少なくともいずれか一方が、写真露光法により形成されたものである請求項9または10に記載の複層ガラスの製造方法。
