Abstract
An object of the present disclosure is to provide a method for manufacturing a multi-layer stack with excellent mechanical strength and thermal insulation properties. A multi-layer stack includes a glass panel unit, an intermediate film, and a transparent plate attached via the intermediate film to the glass panel unit. The glass panel unit includes a first glass panel, a second glass panel, and an evacuated space interposed between the first glass panel and the second glass panel. The method includes assembling the glass panel unit and the transparent plate together via the intermediate film inside an evacuated chamber.
Claims8
A method for manufacturing a multi-layer stack,
- the multi-layer stack including:
- a glass panel unit;
- an intermediate film;
- and
- a transparent plate attached via the intermediate film to the glass panel unit,
- the glass panel unit including:
- a first glass panel;
- a second glass panel;
- and
- an evacuated space interposed between the first glass panel and the second glass panel,
- the method comprising:
- loading, into a chamber, a multi-layer assembly where the glass panel unit is stacked over the transparent plate with the intermediate film interposed between the transparent plate and the glass panel unit;
- then
- evacuating the chamber;
- and then
- making the multi-layer assembly be sandwiched between and heated by a pair of heaters of a heater device installed inside the chamber to assemble the glass panel unit and the transparent plate together via the intermediate film inside the evacuated chamber.
A method for manufacturing a multi-layer stack,

- and
- a transparent plate attached via the intermediate film to the glass panel unit,
- the glass panel unit including:
- a first glass panel;
- a second glass panel;
- and
- an evacuated space interposed between the first glass panel and the second glass panel,
- the method comprising:
- loading, into a chamber, a multi-layer assembly, including the glass panel unit, the intermediate film, and the transparent plate attached via the intermediate film to the glass panel unit, then
- evacuating the chamber and heating the multi-layer assembly by a heater installed inside the chamber, thereby heating the multi-layer assembly inside the evacuated chamber to soften the intermediate film;
- and then
- keeping inside of the chamber evacuated until the intermediate film is cooled and cured while leaving the multi-layer assembly loaded inside the chamber.
