Abstract

The invention discloses an efficient energy-saving making method for vacuum glass, the efficient energy-saving making method uses high temperature in edge banding to directly enter into a vacuum pumping process, and comprises the following steps: (1) arrangement of a support; (2) arrangement of a suction pipe; (3) edge banding and vacuum pumping; and (4) suction pipe nozzle sealing. The characteristics of the method are that: in the edge banding and vacuum pumping process, first placing substrate plate glass in a high pressure heating kettle, before heating, increasing the pressure inside the kettle, then heating to 500-600 DEG C to melt glass powder to seal the periphery of the two pieces of substrate plate glass, then gradually cooling for solidification of the melted glass powder, cooling to the constant-temperature transition warehouse temperature, moving the substrate plate glass into a constant-temperature transition warehouse which is connected with the high pressure heating kettle, and moving the substrate plate glass through the constant-temperature transition warehouse to a vacuum pumping kettle for vacuum pumping. The vacuum pumping kettle temperature is consistent with the constant-temperature transition warehouse temperature. Preferably, the constant-temperature transition warehouse temperature is 350 to 450 DEG C.

Description

The manufacture method that a kind of vacuum glass is energy-efficient and device thereof
Technical field
The present invention relates to vacuum glass manufacture method and vacuum glass manufacturing installation.
Background technology
In modern buildings and car and boat, windowpane is main source of heat release, in cold area, solve door and window heat transfer problem is to adopt double-deck door and window in the past, the application of double glazing has in recent years improved door and window heat transfer problem greatly, but the structural thickness of double glazing is used in conjunction with specific door and window, too high because of its building cost, limited the widespread use of double glazing, particularly the use on covil construction.Therefore, vacuum glass arises at the historic moment, vacuum glass is that a kind of glass of bilayer forms, limit portion sealing between glass and glass, and centre has lining body to support, interlayer is vacuum shape, in interlayer between glass, substantially there is no air, therefore that vacuum glass has is good heat insulation, sound-proofing properties, vacuum glass structural thickness is thinner, is convenient to install.
The production of existing vacuum glass mainly comprises following step: (1) arranges upholder: between two blocks of base material sheet glass, arrange that the miniature upholder nationality of arranging according to certain geometrical rule that meets mechanics requirement is to form the wall of vacuum; (2) arrange extraction pipe: between two blocks of sheet glass, offer aspirating hole, and the Glass tubing of bleeding of coupling is set in hole; (3) edge sealing: at the laying glass powder of the periphery of two blocks of base material sheet glass, and put into High Temperature Furnaces Heating Apparatus and be heated to 600 degrees Celsius, make glass powder fusing, thereby make the border seal of two blocks of base material sheet glass, form cavity, then cooling gradually, the glass powder of fusing is solidified, complete edge sealing operation; (4) vacuumize: until after edge sealing is processed, utilize vacuum extractor to take the air in base material sheet glass folder chamber away by the preset Glass tubing of bleeding; (5) sealing: be connected with vacuum extractor and complete at the Glass tubing of bleeding and carry out the scorification Glass tubing of bleeding while vacuumizing operation, the Glass tubing that makes to bleed melts rapidly and seals aspirating hole.
Existing vacuum glass production technique, the heating of its edge sealing operation and temperature-fall period respectively need the time of effect in 4-6 hour, then just can from High Temperature Furnaces Heating Apparatus, take out the vacuum pumping of carrying out 4-6 hour, production cycle is long, the effective rate of utilization of High Temperature Furnaces Heating Apparatus is low, Edge strength is poor, and fraction defective is high, thereby has caused the economic problems that production efficiency is low and production cost is high.
Summary of the invention
The invention provides the energy-efficient manufacture method of a kind of vacuum glass, to solve the defect that existing vacuum glass manufacture method productivity effect is low, quality product is not high.
In order to reach above technique effect, technical scheme of the present invention is as follows:
The manufacture method that vacuum glass is energy-efficient, comprises the following steps:
(1) arrange upholder;
(2) arrange extraction pipe;
(3) edge sealing and vacuumizing;
(4) sealing.
It is characterized in that: described bag sealer vacuumizes operation, first base material sheet glass is placed in hyperbaric heating still, before heat temperature raising, first improve the pressure in stove, then be heated to 600 ℃, make glass powder fusing, make the border seal of two blocks of base material sheet glass, then cooling gradually, the glass powder of fusing is solidified, cool to when consistent with constant temperature transitional storehouse temperature, base material sheet glass is moved in the constant temperature transitional storehouse being connected with hyperbaric heating still, by transitional storehouse, base material sheet glass is moved to and vacuumizes still and vacuumize.
The described temperature vacuumizing in still is consistent with the temperature in constant temperature transitional storehouse.
As preferably, in the excessive storehouse of described constant temperature, temperature is 350 ℃-450 ℃.
The present invention also provides a kind of vacuum glass manufacturing installation based on vacuum glass glass process of the present invention, comprising: hyperbaric heating still, constant temperature transitional storehouse and vacuumize still.
Described hyperbaric heating still and vacuumize still and be connected with constant temperature transitional storehouse respectively.
Described hyperbaric heating still and vacuumize still and constant temperature transitional storehouse between be equipped with sealed door for storehouse.
The described quantity that vacuumizes storehouse can be a plurality of.
As preferably, the quantity in described vacuum storehouse is 3.
The present invention compared with prior art has following beneficial effect:
Apply a kind of vacuum glass manufacture method of the present invention, there is following technique effect: when (1) carries out edge sealing process, before heating, first pressurize, under the effect of air pressure, two blocks of base material sheet glass pressing tightr, upholder between making is more firm under the effect of pressure, can not be subjected to displacement; (2) under the effect of high pressure, the glass powder of its bonding edge sealing effect can infiltrate a segment distance to gap between two base material flat boards, has increased bond area, and Edge strength is higher; (3) in hyperbaric heating still, without waiting until that substrate glass is cooled to normal temperature gradually, can transfer them in constant temperature transitional storehouse, heat-processed only needs then directly to open hyperbaric heating still and air communication, be reduced to rapidly normal temperature, can carry out hyperbaric heating processing to follow-up product, improve greatly utilization ratio and the production efficiency of hyperbaric heating still; (4) vacuumize operation and at high temperature carry out, during high temperature, density of air is thin, and the air capacity of required extraction still less, vacuumizes efficiency higher, only needs within 1-2 hour, can complete, and vacuumizing effect is better than conventional art; (5) the vacuum glass edge sealing machine vacuum extractor based on the technology of the present invention design, utilize constant temperature transitional storehouse to connect a plurality of stills that vacuumize, through hyperbaric heating still, process base material sheet glass, by constant temperature transitional storehouse, enter respectively the different stills that vacuumizes and carry out vacuum pumping, without wait, make the hyperbaric heating still can continual work, improved greatly production efficiency.
