Description
Technical field
The present invention relates to a kind of vacuum glass production methods.
Background technique
Energy-saving and emission-reduction have been one of fundamental state policies, vacuum glass as a kind of high performance energy-saving glass, increasingly by
The attention of energy-saving field；Vacuum flat glass or hollow plate glass are a kind of heat-insulated, sound insulation rate height, the high high-tech of light transmission
Skill industrial products, production technology are related to the sciemtifec and technical spheres such as vacuum technique, welding technique, automatic technology.Vacuum flat glass
It can be widely applied to building, application of solar energy, freezer box and freezer box transport and agricultural greenhouse greenhouse etc..
The vacuum glass of merchandized handling is generally reheated using installation exhaust pipe after first high temperature edge sealing, cooling and is taken out at present
Vacuum, the two-step method finally sealed, batch production technique, not only production capacity is low, and it is at high cost, qualification rate is low.It is additionally useful for
The substrate of production vacuum glass generally uses tempered glass, the manufacturing method of vacuum tempered glass be on one piece of tempered glass with
Certain intervals place support column, and suitable film layer are plated on tempered glass, but coating and glass bond strength be not high, so
Solder containing pb is smeared at glass surrounding edge sealing afterwards, then another piece of tempered glass is pressed on solder and support column, its is whole
Body is put into vacuum drying oven or on heating platform, is heated to 450 DEG C or more conjunction welderings or sintering, is completed the system of vacuum or hollow glass
It is standby.If soldering object changes simple glass into, because heating temperature is higher than 450 DEG C, simple glass is caused to become semi-tempered glass, institute
It cannot achieve with the prior art and vacuum glass prepared using simple glass.
Summary of the invention
The invention aims to solve the problems, such as that the prior art cannot achieve to prepare vacuum glass using simple glass, and
A kind of method for being prepared using simple glass and having negative-pressure vacuum glass in cavity is provided.
A method of it is prepared in cavity using simple glass with negative-pressure vacuum glass, is specifically realized by the following steps
:
One, frosting treatment: carrying out frosting treatment to the position to be welded of simple glass using physical method or chemical method,
Obtain simple glass after frosting treatment；
Two, magnesium foil or magnesium alloy foil metalized: are cut into the position to be welded with simple glass after frosting treatment
Equivalent width it is band-like, magnesium foil with a thickness of 0.05mm~1mm, magnesium alloy foil with a thickness of 0.05mm~1mm, then carry out clear
It washes, saves under inert gas atmosphere, obtain magnesium ribbon；Magnesium ribbon is laid in common glass after frosting treatment under inert gas atmosphere
On the position to be welded of glass, under inert gas atmosphere with laser aid, microplasma device or high-energy beam device in magnesium
Belt surface carries out Surface scan and is cooled to room temperature until magnesium ribbon is completely melt, i.e., simple glass is to be welded after completion frosting treatment
The metalized of position obtains simple glass after metalized, and after metalized simple glass in inert gas gas
It is saved under atmosphere；
1., under inert gas atmosphere will be equal at the position to be welded of simple glass after two pieces of metalizeds three, assemble:
Solder foil is placed, one of to be used as lower glass plate, another piece is used as upper glass plates, and the solder foil is that fusing point is lower than 450 DEG C
Solder；2., the upper and lower surfaces of sealing frame are subjected to metalized, sealed after obtaining upper and lower surface metalized
Frame；3., the welding position of corresponding lower glass plate sealing frame after upper and lower surface metalized is placed in lower glass plate, upper and lower
Array in frame region is sealed after surface metalation processing and places support column, then corresponds to the welding positions of upper glass plates for upper glass
Plate covers after upper and lower surface metalized in sealing frame, simple glass after being assembled；
Four, vacuum brazing: simple glass after assembling being put into vacuum brazing furnace and carries out vacuum brazing, vacuum degree 1.0
×10-2Pa~5.0 × 10-4Pa, brazing temperature are lower than 460 DEG C, and brazing temperature >=solder foil fusing point, holding time of brazing
For 15min~25min, room temperature is cooled to the furnace, that is, complete to prepare using simple glass in cavity with negative-pressure vacuum glass.

Internal-external temperature difference prevents disclosure risk caused by expansion, contraction unevenness, and the sorrow without aging, service life is substantially improved；Six,
The invention belongs to edge plane sealing tech, seal non-bulging glass surface, reduce transportation volume, have ensured transportation safety.
It is hidden among window frame after installation, it is more beautiful；Seven, the heat-proof quality of negative-pressure vacuum glass is had in cavity prepared by the present invention
It is 2~4 times of hollow glass, is 6~10 times of monolithic glass, independently passively room is to door and window heat transfer using can reach the world
Several requirements；Eight, possessed high vacuum up to 25 years or more with negative-pressure vacuum glass life expectancy in cavity prepared by the present invention
Inner cavity ignores gas heat-transfer, substantially inhibits radiant heat transfer；Nine, compared with three glass, two chamber hollow insulating glass, the present invention
Quantity in the cavity of preparation with negative-pressure vacuum glass only needs two panels heat-insulated, every square metre of weight compared with its reduce 10kg with
On, piece count is less, and glass is more penetrating, possesses excellent daylighting effect；Ten, negative pressure is had in cavity prepared by the present invention
Vacuum glass has prevented interior dew condensation phenomenon from mechanism, compared with hollow glass because of condensation problem caused by internal-external temperature difference, it is outstanding every
Hot insulating power, so that interior surfaces of glass will not condense even if outdoor temperature drops to -40 DEG C.11, present invention preparation
Cavity in have the effective noise reduction of negative-pressure vacuum glass, low and medium frequency noise sound insulation effect stronger for penetration power is significantly high
