Abstract
The invention relates to a method for manufacturing vacuum glass, which comprises the following steps: (1) processing the upper part of an upper piece of glass into an opened pumping through hole; (2) putting support objects on the upper plane of a lower piece of glass and placing the upper piece of glass on the lower piece of glass; (3) sealing vacuum glass edges and glass powder at the pumping through hole; (4) putting the sealed vacuum glass into a vacuum heating chamber for vacuumization at the vacuum degree of 10<-2>-10<-4> Pa and steady heating at 300-500 DEG C for 10-60 minutes in a curve way; and (5) obtaining finished vacuum glass after the sealed vacuum glass is taken out of the furnace when temperature in the vacuum heating chamber slowly drops below 60 DEG C. The invention effectively overcomes the defects of the prior art, simplifies the process, improves the quality of appearance, reduces the manufacture cost of the vacuum glass, is a revolutionary innovation for vacuum glass manufacturing process and greatly promotes the development of the vacuum glass industry.
Description
Technical field
The invention belongs to the vacuum glass field, especially a kind of manufacture method of vacuum glass.
Background technology
Vacuum glass is a kind of heat preserving and insulating material, is usually used in door, window glass of building field etc.Its structure generally is that two parallel placements of glass and its interbody spacer are equipped with upholder, and the edge of two blocks of glass adopts the glass powder with low melting point sealing-in.(its negative pressure is about 10 because of the formed internal space of vacuum glass needs the certain vacuum degree
-2Pa), to realize good and stable thermal and insulating performance, in the vacuum glass manufacturing process technology, need to vacuumize work step.Vacuum glass vacuumizes processing and continues to use traditional technology basically at present, promptly the mode that is communicated to vacuum system by the extraction pipe that is communicated with the vacuum glass internal space realizes vacuumizing, and, this vacuumizes is to adopt long Glass tubing directly to extend to the baking oven outside to link to each other with vacuum system, blows Glass tubing after toasting and vacuumizing and seals.This technology shortcoming is: 1. the interior caliber that seals Glass tubing can not be too big, can only adopt slender glass tube, and the physical strength of this slender glass tube is relatively poor, and generally at high temperature carries out, and operation easier is big; 2. need after sealing to leave over one section Glass tubing that one section similar vacuum flask is taken out mouth, influenced the outward appearance and the whole stress of vacuum glass, reduced yield rate, also influenced the work-ing life of vacuum glass simultaneously.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of can be in baking oven the manufacture method of self-sealing vacuum glass, this method technology is simple, the yield rate height, outward appearance is good.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of step of manufacturing of vacuum glass is:
(1). go up the processing of sheet glass:
To go up and process its top on the sheet glass is the open through hole of bleeding, and quantity is 1-20, uniform desired location;
(2). the storing of vacuum glass:
The last uniform plane of following sheet glass is put upholder, will go up sheet glass then to place down on the sheet glass;
(3). the encapsulation of vacuum glass:
Edge seal between upper and lower vacuum glass is gone into glass powder with low melting point, on made each of last sheet glass is bled through hole, place one be shaped on it in the low melting glass powder of shaft through-hole, and middle shaft through-hole is connected with two formed internal spaces of glass;
(4). the heating of vacuum glass and vacuumizing:
Packaged vacuum glass is put into the vacuum heating chamber internal heating and vacuumize, Heating temperature is 300-500 ℃, and heating up is that flatter curve heats up, and be 30-70 minute the heat-up time of heating up; Progressively vacuumizing, is 10 until vacuum tightness
-1-10
-4Pa;
(5). finished product is come out of the stove:
Come out of the stove when room temp is slow reduces to below 60 ℃ when heating, promptly get the vacuum glass finished product.
And in the placement step of vacuum glass, last sheet glass and following sheet glass justified margin perhaps are slightly less than down sheet glass and to form the limit poor.
And described low melting glass powder is the glass sphere of powder, glass powder post or glass powder ball.
And the periphery of last sheet glass is shaped on a circle leaning angle that makes things convenient for glass powder with low melting point to fill.
Advantage of the present invention and beneficial effect are:
1. the manufacture method of this vacuum glass once can form finished product in that heating under vacuum is indoor, do not need to vacuumize by Glass tubing, the negative pressure of internal space that vacuum glass forms and the balance of the interior negative pressure of heating chamber have been realized, mechanical strength is good, eliminate stress and stress hidden danger that vacuum glass is produced effectively when vacuumizing, prolonged the work-ing life of vacuum glass.
2. this manufacturing approach craft step obtains reducing, and simple to operation, yield rate is higher; Simultaneously, adopt present method on vacuum glass, to leave no trace, improved the visual appearance of vacuum glass.
3. the present invention has effectively overcome the weak point of existing technology, simplify technology, improved visual appearance, reduced the manufacturing cost of vacuum glass, be a revolutionary innovation, the vacuum glass industrial expansion is had greatly promoter action the vacuum glass manufacturing process.

Embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of manufacture method of vacuum glass the steps include:
(1). go up the processing of sheet glass 1:
To go up and process its top on the sheet glass is the open through hole of bleeding, and quantity is 1-20, is 4 through holes of bleeding in the present embodiment accompanying drawing, and uniform desired location.
(2). the storing of vacuum glass:
To descend on the sheet glass uniform plane to put upholder 4, will go up sheet glass then and place down on the sheet glass 5, the edge of last sheet glass should with the justified margin of following sheet glass, perhaps be slightly less than down sheet glass and to form the limit poor; In the present embodiment accompanying drawing, the periphery of last sheet glass is made a circle leaning angle 7, to make things convenient for the filling of glass powder with low melting point.
(3). the encapsulation of vacuum glass:
Edge seal between upper and lower vacuum glass is gone into glass powder with low melting point 3, makes glass powder with low melting point be packed into perimeter; On made each of last sheet glass is bled through hole, place one be shaped on it in the low melting glass powder 2 of shaft through-hole 6 (the low melting glass powder can be the glass sphere of powder, glass powder post or glass powder ball ball, present embodiment is the glass sphere of powder), and shaft through-hole is communicated with two formed internal spaces of glass in making.
(4). the heating of vacuum glass and vacuumizing:
Packaged vacuum glass put into heating under vacuum is indoor to vacuumize and heat, Heating temperature is 300-500 ℃, and heating up is that flatter curve heats up, and be 30-70 minute the heat-up time of heating up, preferred 60 minutes; Vacuumize to progressively carrying out, the vacuum tightness indoor in heating under vacuum reaches 10
