Abstract

The utility model relates to a conical-tail-free flat vacuum glass with noise and heat insulating performance being greatly superior to those of the hollow glass. The vacuum glass comprises two layers of float glass or low-radiation glass; a vacuum layer is formed between the two layers of float glass or low-radiation glass; an atmospheric pressure support is disposed between the two layers of float glass or low-radiation glass; a bonding agent edge sealing layer is disposed on the peripheral edge of the two layers of float glass or low-radiation glass. The outer surface of the two layers of float glass or low-radiation glass is smooth. The conical-tail-free flat vacuum glass has the advantages that compared with other conical-tail protrusion vacuum glass, the production process is simplified, no protrusion exists on the surface, the product appearance is beautiful, the installation and the construction are convenient; the production routing is short; the equipment investment is small; the energy consumption is low; and the production cost is low, and the flat vacuum glass facilitates the generalization and extension of vacuum glass, and achieves the purposes of energy conservation and emission reduction in building.

Description

No vertebra tail planar vacuum glass

Technical field:

The utility model relates to the no vertebra tail planar vacuum glass that a kind of sound insulation, heat-insulating property are higher than double glazing far away.

Background technology:

Sound insulation, the heat-insulating property of science proof planar vacuum glass are higher than double glazing far away.The sound-damping qualities 24--27 decibel of double glazing, the sound-damping qualities 31--45 decibel of vacuum glass; Double glazing heat transfer coefficient 1.8-3.4WM-2K-1, vacuum glass heat transfer coefficient 0.7-0.9WM-2K-1 is than the energy-conservation 35%-40% of double glazing, than the energy-conservation 55%--60% of single-glass.Sound insulation energy-saving effect highly significant, however because vacuum glass manufacturing process complexity, cost is higher, and very difficult big area is promoted the use of.Energy-saving and emission-reduction are strategic objectives of China's Economic development.

At the vacuum glass production field, the making processes of existing data report planar vacuum glass is: 1 glass cuts out → 2 hole → 3 of making an installation vacuum extractor for a sheet glass wherein adorn extraction pipe → 4 one sheet glass and weld with extraction pipe in the hole → 5 give another sheet glass place tackiness agent and Chinese People's Anti-Japanese Military and Political College's atmospheric pressure upholder → 6 close sheet → 7 send into high-temperature chamber carry out bonding → 8 coolings → 9 to extraction pipe install well heater → 10 vacuumize → 11 to glass heat again → 12 melt seal gas extraction ducts → 13 ten three process such as welding the extraction pipe tin hats be installed.The vacuum glass of Zhi Zuoing stays an extraction pipe vertebra tail ridge on the surface like this, is unfavorable for the recombinant of vacuum glass; Produce that route is long, power consumption is high, damaged easily when product has the tail of bleeding and installs, investment of production equipment is big, the product cost height is unfavorable for that big area promotes the use of.

Summary of the invention:

The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, production cost is low, be not provided with the no vertebra tail planar vacuum glass of vertebra tail at glass surface.

The purpose of this utility model is achieved in that and comprises two-layer float glass process or low emissivity glass, it is characterized in that: between two-layer float glass process or low emissivity glass, be vacuum layer, being provided with barometric point in vacuum layer between two-layer float glass process or the low emissivity glass supports, two-layer float glass process or low emissivity glass surrounding are along being provided with the tackiness agent bead layer, and the outside surface of two-layer float glass process or low emissivity glass is slick surface.

Have groove on the two-layer float glass process in vacuum layer or the wherein layer of surface of low emissivity glass, in this groove, be placed with getter.Described tackiness agent bead layer is high-temperature adhesives layer or low-temperature adhesive layer.

The utility model does not have vertebra tail ridge in appearance, has vertebra tail ridge vacuum glass to compare with other producers and has reduced production link; Appearance does not have ridge, and product is more attractive in appearance; Help installation, help vacuum glass and double glazing, doubling glass, multiple glazing deep processing, expanded the range of application of vacuum glass.And production line is short out, facility investment is little, power consumption less, production cost is low, helps this novel building energy-saving material of vacuum glass in national penetration and promotion, reaches the purpose that building energy conservation reduces discharging.
