The present invention relates to a method for manufacturing vacuum insulating glass, the method involving applying a vacuum sealant to a first surface of a first glass sheet, the vacuum sealant including a plastic film having a preferably rough surface, placing a second glass sheet on the vacuum sealant such that a cavity is formed between the first and second glass sheets and the vacuum sealant, applying a vacuum to an outer surface of the vacuum sealant until a vacuum is formed in the cavity, wherein the first and second glass sheets are placed in a vacuum bag to apply the vacuum, and heating the vacuum sealant while the first and second glass sheets are in the vacuum bag.

Certain example embodiments relate to an insulating glass (IG) unit. A spacer system is interposed between first and second substrates. The spacer system helps to maintain the first and second substrates in substantially parallel spaced apart relation to one another, and to define a cavity between the first and second substrates. A desiccant material is located in a body of the spacer system, with the desiccant material comprising a desiccant matrix and a molecular sieve replacement material formed for adsorption at a relative humidity of 10-20%. The molecular sieve replacement material may be a salt or other material (such as, for example, MgCl.sub.2, CaCl.sub.2, CaO, MgSO.sub.4, and/or the like). The cavity may be primarily filled with an inert gas (such as Ar, Kr, Xe, or the like) or a reactive gas (such as CO.sub.2). An electrostatically-driven dynamic shade may be provided in the cavity.

Provided is a vacuum insulation glass panel assembly manufacturing method and apparatus. The vacuum insulation glass panel assembly manufacturing method includes an edge sealing step of sealing an edge of a glass panel assembly of glass panels spaced apart at a predetermined interval, and an exhaust port sealing step of causing a lid member to seal an exhaust port of the glass panel assembly formed so as to communicate with a space between the glass panels whose edges are sealed. A glass solder having a high melting point is used in the edge sealing step, and a glass solder having a low melting point is used in the exhaust port sealing step. A specially designed lid member closing device is used for exhaust port sealing.

A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.

The invention relates to a gasket for evacuation a void in a vacuum insulated glazing unit, a method for producing a vacuum insulated glazing unit, a gasket for use in the production of a vacuum insulated glazing unit and apparatus comprising an evacuation cup and a gasket. The present invention furthermore relates to the use of a gasket. The gasket is adapted for being positioned between the outer surface of the first pane and an evacuation cup, the evacuation cup comprising, a first cavity with a first cavity opening, an exhaust opening for evacuating the void via the first cavity opening, an evacuation cup body and one or more contact surfaces wherein the gasket is adapted to provide an air tight seal between the evacuation cup and the first glass pane during evacuation of the void, wherein the gasket comprises a gasket material which constitutes the majority of the gasket, is compressible between the evacuation cup and outer surface of the first pane with an out of plane module of elasticity below 50 GPa, such as below 30 GPa, such as below 25 GPa and has a melting temperature above 400 degrees Celsius.

The disclosure discloses a manufacturing method of tempered vacuum glass, comprising the following steps: (1) manufacturing metalized layers, and performing tempering or thermal enhancement on the glass substrates; (2) placing a metal solder on the metalized layers; (3) superposing the glass substrates to form a tempered glass assembly; (4) heating the tempered glass assembly to 60-230° C.; (5) keeping the tempered glass assembly within the heating temperature range of step (4) in a vacuum chamber, and vacuumizing the vacuum chamber to a preset vacuum degree; and (6) hermetically sealing the metalized layers by adopting a metal brazing process. By adopting the manufacturing method of the disclosure, the stress when the two glass substrates are sealed can be greatly reduced, and the connection strength can be increased; moreover, when gas is exhausted within the temperature range, the exhaust efficiency is high, and the exhaust effect is better, vacuum glass with high vacuum degree can be obtained, and the service life of the vacuum glass is prolonged.
