Description
Technical field
The present invention relates to a kind of vacuum glass processing and manufacturing technical field, a kind of manufacture method of vacuum glass specifically.。
Background technology
The building energy consumption of China accounts for 1/4 of total energy consumption, the door and window energy consumption of wherein building accounts for 50% of building energy consumption, and along with modern architecture door and window simple glass shared by ratio increasing, door and window energy consumption accounts for the 65-70% of building total energy consumption, therefore, modern architecture needs to select energy-saving glass, and at present, energy-saving glass application is more is double glazing and vacuum glass.Vacuum glass is by airtight for two panels sheet glass surrounding, its gap is evacuated and seal vents, gap between two sheet glass is 0.1-0.2mm, the two panels of vacuum glass generally has at least a slice to be low emissivity glass, so just by the heat drop that scattered and disappeared by the conduction of vacuum glass, convection current and radiation mode to minimum, vacuum glass has because thermal resistance is high relative to simple glass and double glazing, and antisweat frosting performance is better; The advantages such as sound insulation property is good.And there is fine energy-saving effect.
The typical structure of vacuum glass as shown in Figure 1 in the market, and between two panels sheet glass 01,02, namely place the miniature upholder 03 arranged according to certain geometrical rule meeting mechanical requirements, nationality is to form the wall of vacuum.Periphery low melting glass braze sealing, sheet glass 01 is wherein provided with aspirating hole, is provided with extraction pipe 04 in aspirating hole, carries out vacuum suction by extraction pipe 04, and forms vacuum heat-insulating layer after sealing.With the operation of low melting glass braze seal perimeter be one heating process and edge sealing.Its complex manufacturing, difficulty of processing is comparatively large, and production capacity is lower; And the vacuum tightness of vacuum glass is difficult to ensure.
Summary of the invention
The present invention is directed to the shortcoming of the problems referred to above for current production method for vacuum glass, provide a kind of difficulty of processing low, and the manufacture method of vacuum tightness vacuum glass can be ensured.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of manufacture method of vacuum glass, first to glass process in early stage, early stage, process comprised out Jie, edging, brill cuts aspirating hole, cleaning, make sheet glass and lower sheet glass on vacuum glass, by the avris portion gluing at lower sheet glass and lower sheet glass, and dry under 80-120 DEG C of low temperature, place lower sheet glass, and upholder is put on lower sheet glass, the avris of upper sheet glass with lower sheet glass is alignd, and place at aspirating hole place Glass tubing of bleeding, carry out adding heat sealing, its Heating temperature is 400-450 DEG C, and a reserved glass tube seat of bleeding, glass complete for sealing-in is put into vacuum oven and carries out second time bake out, vacuum oven Heating temperature 200-300 DEG C, vacuumize, the vacuum tightness of vacuum oven is made to be less than 1*10-
3pa, adds heat-sealable Glass tubing of bleeding by heating wire in vacuum oven.
The second-heating temperature of described vacuum oven is 260 DEG C.
Described heating sealing temperature is 420 DEG C.
Described vacuum glass adds heat sealing to be completed in process furnace; Seal Glass tubing of bleeding to complete in vacuum oven.
In described photoresist coating process, gluing width should keep between 10-15mm.
The invention has the beneficial effects as follows: the processing method adopting invention, first vacuum oven is vacuumized, reach the vacuum tightness that vacuum glass needs to reach, heat-sealable Glass tubing of bleeding is added again by heating wire, make the vacuum tightness of vacuum glass can not destroy the vacuum tightness of vacuum glass because of air inlet in scorification process, and this scorification is easy to operate, greatly can boost productivity, improve the production capacity of vacuum glass.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Vacuum glass of the present invention as shown in Figure 2, vacuum glass raw sheet comprises two blocks of glass placed in opposite directions, an interval is had between two blocks of glass, multiple upholder 2 is placed with in this interval, upholder 2 is between the upper and lower apart from being 30mm, and for maintaining the interval between two blocks of glass, vacuum glass raw sheet can adopt conventional glass, such as, float glass, add a glass, coated glass, stained glass etc.Upholder 2 can be conventional upholder, such as, and the upholder prepared by materials such as metal, pottery, alloys.The tube seat 10 of accommodating Glass tubing of bleeding is established in avris position inside two pieces of vacuum glass raw sheets, is provided with Glass tubing 3 of bleeding in tube seat.Glass tubing 3 of bleeding adopts the Glass tubing of 1 ~ 1.2mm diameter.Tube seat 10 structure of bleeding as shown in Figure 3, the single-glass of vacuum glass, its thickness generally adopts the glass being greater than 3mm, hole in the horizontal direction from its side position, and then in glass inner layer, bore the room of and parallel direction handing-over, such sealing-in effect is better and process and convenient operation in sealing-in at the silk-screen of product.
Vacuum glass manufacture method is as follows: the production process in early stage first completing glass, comprise out the techniques such as Jie, cleaning, edging, boring, then in the avris gluing of lower sheet glass and lower sheet glass, beat glue width should keep between 10-15mm, and dry under 80-120 DEG C of low temperature, place lower sheet glass, and on lower sheet glass, put upholder 2, upholder 2 between the upper and lower distance is 30mm.Alignd with bottom sheet glass avris by upper sheet glass, and place at aspirating hole place Glass tubing 3 of bleeding, carry out adding heat sealing, heating sealing temperature is 400-450 DEG C, preferable temperature about 420 DEG C.Vacuum glass adds heat sealing can be completed in process furnace.And a reserved glass tube seat 1 of bleeding, glass complete for edge sealing-in is put into vacuum oven 4 and carries out second time bake out, vacuum oven 4 Heating temperature 200-300 DEG C, carries out suction, makes the vacuum tightness of vacuum oven 4 be less than 1*10-
3pa, adds heat-sealable Glass tubing 3 of bleeding by heating wire 5 in vacuum oven 4.
As shown in Figure 4, glass complete for sealing-in is put into vacuum oven 4 and carries out second time bake out, its optimum heating temperature is 260 DEG C and 1*10-
3the Working environment of Pa vacuum tightness; the residual gas of inside glass is got rid of completely then in vacuum oven 4 by heating wire 5 direct heating sealing glass pipe 3 (aspirating hole position); in the process of heating sealing glass pipe 3; we prevent glass complete to sealing-in in heat-processed from melting thermal distortion at Glass tubing lateral septal Thermal protection lid 6.
Adopt the processing method of invention, first vacuum oven is vacuumized, reach vacuum glass need reach vacuum tightness, heat-sealable Glass tubing of bleeding is added again by heating wire, make the vacuum tightness of vacuum glass can not destroy the vacuum tightness of vacuum glass because of air inlet in scorification process, the vacuum tightness that this method by the inner directly sealing-in of vacuum oven bake out can improve product itself plays better sound insulation, effect of heat insulation, and in volume production, had breakthrough progress, and quality guarantee, yield rate is high.
Above-described embodiment is illustrative principle of the present invention and effect thereof only; and the embodiment that part is used, for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
