Further, without using a photographic exposure method, a spacer formed of a material such as a metal, which is used in a conventional multilayer glass, is dispersed and arranged at a predetermined position on the front surface 2a of the plate glass 2 on the back side. Alternatively, it can be bonded. In addition, when not using the photographic exposure method for the formation and arrangement of the spacer, by using a spherical or cubic shape as the spacer, even when the orientation of the spacer is different when arranged on the surface of the plate glass, The distance between the pair of plate glasses can be accurately defined.
- a spacer is not necessarily required and it is also possible to employ
- the spacer can be formed on the inner surface of the front glass plate.
- the frit seal 4 and the partition wall 5 are not melted, the height of the frit seal 4 and the partition wall 5 is formed higher than the height of the spacer 6. For this reason, the plate glass 3 on the front side is placed on the tops of the frit seal 4 and the partition wall 5, and a gap is formed between the plate glass 3 and the tops of the spacers 6.
- FIG. 5 shows the setting conditions of the melting step for melting the frit seal 4 and the partition wall 5 and the exhausting step for exhausting the air in the space between the pair of plate glasses 2 and 3 in the method for producing a double-layer glass of the present embodiment. It is a figure which shows an example.
- the ultimate temperature of the melting furnace is higher than the softening temperature 434 ° C. of the glass frit used for the frit seal 4 and the partition wall 5, for example, 450 ° C. To do.
- the frit seal 4 starts to melt, the peripheral portions of the pair of glass sheets 2 and 3 are sealed, and a sealable space A is formed between the pair of glass sheets 2 and 3.
- the partition wall 5 starts to melt, and the contact portion between the partition wall 5 and the sheet glass 2 and the sheet glass 3 is welded, but the furnace temperature in the first melting step is a temperature slightly higher than the softening point temperature of the glass frit.
- the partition wall 5 is not greatly deformed, and the slit 5a formed in the partition wall 5 is not blocked.
- the maximum temperature in the first melting step is maintained at 450 ° C., and the maintenance time (require time) Is set within a range in which the slit 5a of the partition wall 5 is not blocked.
- the maintenance time (T1) in the first melting step is 10 minutes as an example.
- the air in the space A is exhausted by a vacuum pump once the temperature of the melting furnace is lowered to a temperature of 434 ° C. or lower, which is the softening point temperature of the glass frit, for example, 380 ° C.
- the exhaust process is started. Since the temperature of the melting furnace is set lower than the softening point temperature, the frit seal 4 and the partition wall 5 are not melted and deformed during the exhaust process.
- the degree of vacuum in the space A is preferably 0.1 Pa or less from the viewpoint of ensuring heat insulation as a characteristic of the double-glazed glass.
- the higher the degree of vacuum the higher the heat insulating properties of the double-glazed glass, but in order to obtain a higher degree of vacuum, it is necessary to improve the performance of the vacuum pump and lengthen the exhaust time, which increases the manufacturing cost. It becomes a factor. For this reason, it is preferable from the viewpoint of manufacturing cost that the vacuum degree that can secure the necessary characteristics as the double-glazed glass is not limited to a higher vacuum degree than necessary.
- the set temperature in the exhaust process when the set temperature in the exhaust process is lowered, it takes time to increase the temperature until the second melting process described later. For this reason, it is effective to set the set temperature at the start of the evacuation process to a temperature slightly lower than the softening point temperature of the glass frit from the viewpoint of shortening the time required for the entire melting process and the evacuation process. For example, by setting the set temperature in the exhaust process to 420 ° C. and the maintenance time (T2) to 120 minutes, the space inside the double-glazed glass can be exhausted satisfactorily.
- the temperature of the melting furnace is raised to 465 ° C. as the second melting step while the space A is being exhausted.

- the spacer 6 having a height of 100 ⁇ m is disposed as an example, and therefore the distance between the plate glasses 2 and 3 is defined as 100 ⁇ m, which is the height of the spacer.
- the force in the direction in which the distance between the glass plates 2 and 3 is reduced acts, so that the melted frit seal 4 and the partition wall 5 are crushed from above and below to increase the width when viewed in plan. For this reason, the pair of glass plates 2 and 3 are more firmly and securely sealed by the frit seal 4, and the slit 5 a that is a ventilation portion formed in the partition wall 5 is crushed and closed.
- the space A is divided into an exhaust port region B on the side including the exhaust port 7 and a decompression region C that is a region other than the exhaust port region.
- a mechanical pressing force can be applied to at least one of the plate glasses in the direction of narrowing the interval between the plate glasses as necessary.
- the partition wall 5 In the second melting step, it is important that the partition wall 5 is sufficiently melted as described above, and the slit 5a that is the ventilation portion is reliably closed.
- the maintenance time (T3) at the set temperature of 465 ° C. in the second melting step to 30 minutes, the partition wall 5 can reliably divide the space A into the exhaust port region B and the decompression region C. it can.
- the distance between the plate glass 2 and the plate glass 3 becomes a predetermined interval defined by the spacer 6, the slit 5 a of the partition wall 5 is completely closed, and the space A is an exhaust port region. After being completely separated into B and reduced pressure region C, the temperature of the melting furnace is lowered and the double glazing is taken out.
- the space A is divided into the exhaust port region B and the decompressed region C by the partition wall 5.
- the decompression region C is kept in a decompressed state.
- FIG. 7 shows a melting step for melting the frit seal 4 and the partition wall 5 and an exhausting step for exhausting the air in the space A between the pair of plate glasses 2 and 3 in the method for producing a multilayer glass of the present embodiment.
- Another setting condition example is shown.
- Another setting condition shown in FIG. 7 is different from the setting condition shown in FIG. 5 and is characterized in that the multi-layer glass is lowered to room temperature after the first melting step.
- a first melting step is performed in which the frit seal 4 is melted to seal the pair of glass sheets 2 and 3 to form the space A.
- the setting conditions of the first melting step are the same as those shown in FIG. 5, 450 ° C., where the highest temperature is higher than the softening point temperature 434 ° C. of the glass frit used for the frit seal 4 and the partition wall 5.
