Description
Technical field
Heat insulation glass manufacturing technology field is the utility model is related to, particularly a kind of vacuum glass for being easy to vacuum pumping
Glass.
Background technology
Vacuum glass is by two panels plate glass all round closure, and its gap is evacuated and seal vents, two
Gap between piece plate glass is 0.1-0.2mm, in the two panels plate glass of vacuum glass it is general it is at least a piece of be low spoke
Penetrate glass, thus will by the conduction, convection current and radiation mode of vacuum glass scatter and disappear heat be preferably minimized, its operation principle with
The insulation principle of glass vacuum-bottle is identical.Vacuum glass is glass technology and material science, vacuum technique, physical measurement skill
Art, industrial automation and architecture science etc., the outstanding achievement that a variety of subjects, multiple technologies, kinds of processes combine.Its major technique effect
It is：Energy-conservation, heat-insulated, sound insulation.
The normal temperature vacuum pumping method of existing vacuum glass, its step are：
（1）Two sheet glass that cloth is put well to supporter close piece, and edge fluting places getter and glass exhaust tube, the glass
Blind head is made in the outer end of exhaust tube, with glass powder with low melting point by the edge edge sealing between two sheet glass.
（2）Two sheet glass after conjunction piece are sent into atmospheric pressure kiln, the atmospheric pressure kiln is conventional tunnel cave or box
Stove, 350-500 DEG C will be warming up in stove, be incubated 20-40 minutes, be come out of the stove when being then naturally cooling to close to room temperature.
（3）Sintering vacuum glass after coming out of the stove, which moves to, unseals blind head tube, vacuum glass modes of emplacement by vacuum pump assembly
Can with multi-disc side by side cube, can also multi-disc level stack.The glass tube that solution is honored as a queen is docked with vacuum pump assembly, taken out at room temperature
Vacuum.Vacuum pump assembly can be conventional use of mechanical pump+oil diffusion pump and a subsidiary buffering pipe, divide on buffering pipe
Multiple bleeding point locking devices and shutoff valve are not installed, in order to carry out vacuumizing for multiple vacuum glass simultaneously, improve life
Produce efficiency.
（4）When vacuum glass intracavitary negative pressure reaches 7*10-1pa-10-2During pa, hot melt is heated into the root of glass exhaust tube
Sealing, it is that multi-disc electric boiling plate or resistance wire are heat-sealable that it, which heats heat sealing mode, or flame naked light heat sealing, is thus obtained
Obtain vacuum glass.
In actual use, there are the following problems for above-mentioned vacuum pumping method：
A, glass exhaust tube insertion glass needs to be sent into atmospheric pressure kiln after closing piece, after heating edge sealing sizing, glass pumping
Tube capacity is also easy to produce crooked phenomenon, and this influences whether to vacuumize quality.
B, because glass exhaust tube may be different from the fusing point of glass lamellar body, easily produced after normal heating stove heat is sent into
Raw clogging, has influence on and vacuumizes.
C, after vacuum pumping, the root of glass exhaust tube is only by heating heat sealing, because sealing is directly exposed
Outside product, it is thus possible to as the weak link of product, once that is, seal quality is bad or external cause damages sealing part, be easy for making
Into the failure of vacuum glass.That is, prior art lacks the further protection to closure part.
D, after vacuum pumping, the root of glass exhaust tube is also easily caused by heating heat sealing in this step operation
Air enters, and causes vacuum glass to fail.
