摘要： A method for manufacturing a glass panel unit includes an assembling step, a gas exhausting step, and a sealing step. At least one of a first glass pane or a second glass pane includes a low-emissivity film. In a situation where the low-emissivity film is heated at a temperature increase rate of 4° C./min before a peripheral wall is melted, a ratio of an emission quantity of a rare gas emitted from the low-emissivity film at a deformation temperature of the partition to an emission quantity of the rare gas emitted from the low-emissivity film at 100° C. is equal to or less than 2.0.

摘要： Provided is a glass panel unit that reduces the chances of an electric wire extended being disconnected. A glass panel unit includes a first panel, a second panel, a seal, a connecting void, and an electric wire. The first panel includes a first glass pane. The second panel includes a second glass pane and is arranged to face the second glass pane. The seal has a frame shape and hermetically bonds respective peripheral edge portions of the first panel and the second panel to create an internal space between the first panel and the second panel. The connecting void is provided for a portion, other than a portion facing the internal space, of at least one of the first panel or the second panel. The electric wire is extended from the internal space to the connecting void by passing through the seal.

摘要： A method for manufacturing a multi-layer stack includes bonding a transparent plate to an outer surface of at least one of a first glass panel or a second glass panel of a glass panel unit with an intermediate film interposed therebetween. The glass panel unit includes: the first glass panel; the second glass panel; and an evacuated space provided between the first glass panel and the second glass panel. A plurality of spacers are provided in the evacuated space between the first glass panel and the second glass panel. A pressure applied for bonding the glass panel unit and the transparent plate together is less than a compressive strength of the plurality of spacers.

摘要： A glass panel unit manufacturing method includes a bonding step, an insertion step, an evacuation step, and a sealing step. The bonding step includes bonding a first substrate having an evacuation port and a second substrate with a bonding material having a frame shape to form an internal space. The insertion step includes inserting a sealing material into the evacuation port. The evacuation step includes evacuating the internal space by connecting an exhaust device to the evacuation port and driving the exhaust device. The sealing step includes sealing the evacuation port with the sealing material while an evacuated state in the internal space is maintained. In the sealing step, a measured value by a pressure gauge is monitored while the sealing material is heated, softening of the sealing material is detected based on the transition of the measured value, and heating of the sealing material is stopped.

摘要： A glass panel unit according to an example of the present disclosure includes a first glass panel and a second glass panel disposed to face the first glass panel. The glass panel unit includes: a seal having frame shape and hermetically binding the first glass panel and the second glass panel together; and a depressurized space surrounded by the first glass panel, the second glass panel, and the seal. The glass panel unit includes spacers between the first glass panel and the second glass panel. The spacers include a macromolecular resin material including molecular chains. Of the molecular chains, the number of molecular chains oriented in an orthogonal direction is larger than the number of molecular chains oriented in a counter direction. The orthogonal direction is a direction orthogonal to the counter direction, which is a direction in which the first and second glass panels face each other.

摘要： An object of the invention is to provide a glass panel unit manufacturing method and a glass window manufacturing method which enable a binder to be effectively removed from a glass adhesive, provide high adhesive strength between panels, and enable a vacuum space to be stably formed. A method for manufacturing a glass panel unit includes: disposing a glass adhesive to have one part as a low step part thinner than the other part of the glass adhesive; disposing a first substrate including at least a first glass substrate and a second substrate including at least a second glass substrate to face each other; and heating glass composite to form an inner space; reducing the pressure of the inner space; and forming a vacuum space from the inner space. The glass adhesive includes glass powder and a binder.

摘要： The multiple pane includes: a first glass panel; a second glass panel disposed facing the first glass panel with a predetermined interval in-between; and a hermetically-bonding member hermetically bonding peripheries of the first glass panel and the second glass panel to form a hermetically-enclosed space between the first glass panel and the second glass panel. The multiple pane further includes an adsorbing member which is fixed on a surface of the first glass panel so as to be inside the hermetically-enclosed space, has a height equal to or less than a length of the predetermined interval, and is for adsorbing a gas inside the hermetically-enclosed space. The hermetically-enclosed space is made to be in a reduced-pressure state.

摘要： The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer contains polyimide represented by chemical formula (1):
