Description
Technical field
The present invention relates to the production method of a kind of production method of glass, particularly a kind of vacuum glass.
Technical background
On modern building, at a large amount of use glass.The double glazing unit that current trend is used is as door, window and body of wall glass, the major technology index, and sound insulation, heat-proof quality are better than single-glass.Yet compare with double glazing, it is better that the sound insulation of vacuum glass, heat-proof quality seem.The hot through-flow rate of individual layer vacuum glass is at 1.0kcal/m
2About hr ℃, and the hot through-flow rate of double glazing is up to 3.0kcal/m
2More than hr ℃.Hot through-flow rate 0.3～0.5kcal/m with body of wall
2Compare for hr ℃, on buildings, can use multilayer, composite evacuated glass, sound insulation, the thermal resistance performance of buildings just seemed particularly important.
The production method of vacuum glass is in the prior art: place some upholders between two sheet glass, seal with seal, sealing materials around two glass sheets, on last sheet glass, venting hole is set, by the air between two sheet glass of air extractor emptying, make and be in vacuum state in the hollow, then venting hole is shut, made vacuum glass, as; It is single back-up block or back up pad that CN02243513.1 discloses a kind of placement upholder, and CN02128829.1 discloses a kind of technology of nichrome upholder of the C of placement shape.
