A. two glass plates all need the processing through overground straight flange chamfering or rounding arc, have increased operation and manufacturing cost, and glass easily produces in frequent handling process and collides with and scratch.
B. glass powder with low melting point is not easy to stop between the chamfering of two glass sheets or circular arc, easily comes off in high temperature sintering.
C. use seal, sealing materials many.
2. the process that vacuumizes processing mainly contains two kinds:
Shown in first kind (as accompanying drawing 2), be buckled on the exhaust opening of vacuum glass with a cup-shaped device (being commonly called as vacuum cup) that has silicon rubber loop, be connected on the vacuum system by metal bellows, after toasting and vacuumizing, shut exhaust opening with spotlight or electrically-heated coil, the weak point that this method exists at present is: 200 ℃ of the high-temperature resistants of silicone rubber O-ring, can not be baked to high temperature more than 300 ℃, thus insufficient quality and the stability that influences product of glass exhaust.
Shown in second kind (as accompanying drawing 3), the glass plate of sealing the edge is placed in the big vacuum chamber, is found time with the gap of glass plate in the space in the vacuum chamber, make to produce needed vacuum in the gap of this glass plate.In vacuum chamber, start original already installed closing device then, exhaust opening is shut, obtain having the vacuum glass of required vacuum.This method, what solved that first method exists can not be baked to deficiency more than 300 ℃, but thing followed problem is to increase large-scale vacuum equipment, has prolonged the process-cycle, has improved the manufacturing cost of product.Owing to inconsistent, produced bigger stress in addition, also caused certain quality hidden danger in the cooling velocity of vacuum chamber inside exhaust pipe and glass plate.
3. the material of supporter, shape and processing method.Each patent had proposed the material of many supporters in the past, had roughly comprised materials such as metal, plastics, glass, pottery.Shape has (as accompanying drawings 4) such as bar shaped, disc, annular, netted shape, spheroidal, cydariforms.Their ubiquities processing technology complexity, manufacturing cost height,, the defectives such as conduction of heat that increased vacuum glass big with the glass contact area.Processing method to supporter is not generally described.
4. the mounting method of exhaust opening glass tube, the principal mode of each patent (as accompanying drawing 5) was to bore a stepped hole or taper hole makes the aperture of upper end identical with the stack diameter at the edge of last sheet glass in the past, the aperture of lower end is less than the aperture of glass tube, so that prevent coming off of exhaust glass tube.The shortcoming of this method is that drilling depth is not easy control, and the exhaust glass tube is laid and is not easy perpendicular to glass plate, has influenced the quality of sealing.
Summary of the invention (1). reduce the edging chamfering process of two glass plates, make the agent of glass powder with low melting point sealed knot carry out sealing-in with comparalive ease and save material.
(2). propose a kind of new treatment process method that vacuumizes, improve the weak point that past method exists.
3. change the shape of supporter, the material of clear and definite supporter and processing method.
4. the form of laying of reform exhaust opening boring form and exhaust glass tube is improved the quality of products.
Description of drawings is totally six page of 11 figure.Fig. 1 represents " vacuum glass basic block diagram ", Fig. 2 represents " vacuum cup vacuum-pumping and sealing structure chart ", Fig. 3 represents " vacuum-pumping and sealing structure chart in the vacuum chamber ", Fig. 4 represents " several shapes of former supporter ", Fig. 5 represents " principal mode of steam vent in the past ", Fig. 6 represents " several laying methods of edge seal material in the past ", Fig. 7 represents " new C type buttress material structure chart ", Fig. 8 represents " new edge seal material brushing technique figure ", Fig. 9 represents " the mounting structure figure of stack ", Figure 10 represents " a kind of new air extractor structure chart ", Figure 11 represents " the air extractor structure chart that another is new ".
The specific embodiment is in order to solve existing technological problems in the vacuum glass manufacture process, and the invention of this technology provides a kind of new vacuum glass manufacturing process, and it is realized by following scheme:
A. the glass powder with low melting point sealed knot agent (as accompanying drawing 8) of smearing (printing) certain width and thickness at the edge of following glass sheets.
B. up and down between the glass sheets arrangement pitch be C shape metal (Ni20Ci80) supporter (as accompanying drawing 7) of 20mm-25mm, make it obtain an equal gap of going up lower glass plate.
C. on the angle of last glass sheets, open a through hole with the identical bore of exhaust glass tube, put into a slice getter inserts an end band inclined-plane again in the hole exhaust glass tube earlier, be inserted in sealed knot glass dust sheet simultaneously.Behind sintering, become exhaust opening (as accompanying drawing 9).
