Abstract: A glass panel unit manufacturing method includes disposing a glass adhesive on a first substrate, disposing a second substrate to face the first substrate, forming an inner space between the first substrate and the second substrate, reducing the pressure of the inner space, and forming a reduced-pressure space from the inner space. The glass adhesive includes glass powder having an average particle diameter larger than or equal to 25 μm and smaller than or equal to 30 μm.

Abstract: The objective is to propose a production method of multiple panes which can be simple and nevertheless produce a multiple pane in its finished state which does not include any undesired protrusion from an external surface of a glass panel. The production method includes: hermetically bonding, with a sealing member, peripheries of paired glass panels disposed facing each other at a predetermined distance to form a space to be hermetically enclosed between the glass panels; evacuating air from the space through an outlet to make the space be in a reduced pressure state; subsequently dividing the space by a region forming member disposed inside the space to form a partial region which do not include the outlet; and subsequently cutting out the partial regions by cutting the pair of glass panels.

Abstract: Provided are a glass panel unit and a method for manufacturing the glass panel unit, both of which are designed to overcome the problem of poor handleability of known glass panel units with no through holes. A glass panel unit includes a first panel, a second panel, a seal, and a boundary wall. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel. The boundary wall partitions an internal space into a first space as a hermetically sealed evacuated space and a second space spatially separated from the first space. The first panel has a first through hole provided through a portion, corresponding to the second space, of the first panel. The second panel has a second through hole provided through a portion, corresponding to the second space and facing the first through hole, of the second panel.

Abstract: The assembling step is a step of preparing an assembly. The setting step is a step of setting a plurality of holder installation areas along an outer peripheral edge of the peripheral wall. The determining step is a step of determining a first area in which the slit and the peripheral wall are not adjacent to each other in the first area and a second area in which the slit and the peripheral wall are adjacent to each other. The installation step is a step of providing a holder in the first area without providing the holder in the second area.

Abstract: A glass panel unit manufacturing method includes a glue arrangement step, a pillar forming step, an assembly forming step, a bonding step, an evacuation step, and a sealing step. The glue arrangement step includes arranging a hot glue including a frame member and a partition on either a first panel having a predetermined degree of warpage or a second panel. The pillar forming step includes placing pillars on either the first or second panel. The assembly forming step includes forming an assembly. The bonding step includes heating the assembly with the first panel arranged to form an upper part of the assembly and the second panel arranged to form a lower part of the assembly to bond the first panel and the second panel together. The evacuation step includes reducing pressure in an internal space. The sealing step includes creating a hermetically sealed evacuated space by closing an exhaust port.

Abstract: A glass panel unit assembly includes a pair of glass substrates arranged to face each other, a peripheral wall, a partition, an air passage, and an evacuation port. The peripheral wall has a frame shape and is provided between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition has a broader width than the peripheral wall.

Abstract: A method for manufacturing a glass panel unit, which reduces the amount of a getter material to enable a gettering ability to be realized at a relatively low temperature less likely to cause damage. The method includes a step of producing a getter material by heating an unprocessed getter material at a temperature higher than a prescribed temperature Te; a step of producing a preassembled component including a first and second glass pane, a heat-fusible sealing material, an internal space, and a gas adsorbent containing the getter material, and an evacuation port; a step of forming a frame body hermetically bonding the first glass pane and the second glass pane together by melting the heat-fusible sealing material with heat; and a step of heating the gas adsorbent at the prescribed temperature Te while the internal space is evacuated by exhausting air in the internal space through the evacuation port.

Abstract: A gas adsorbent is placed on at least a surface of a first plate on one side in a thickness direction thereof or a surface of a second plate on one side in a thickness direction thereof. The gas adsorbent has a shape with relatively raised and lowered parts arranged alternately. The gas adsorbent is placed along a sealant that joins the first and second plates.
