Abstract
The dry sheet-joining method for prodcing composite fire-proof glass by using single-sheet glass includes the following main steps: 1. the glued-layer surfaces of two fire-proof glass single sheets are fastened together; 2. they are placed in a rubber bag connected with vacuum pump, evacuated, and the pneumatic pressure in the rubber bag is kept at 100-950 Pa for 30-60 min.; 3. the rubber bag is heated for 30-60 min. by using hot air of 50-100 deg.C, and at the same time the pressure in the bag is continuously retained; 4. the heating operation is stopped, the pressure in the bag also is retained and the temp. is reduced to 40 deg.C, the evacuation system is closed; 5. the temp. is reduced to room temp., and the edge is finished so as to obtain the invented fire proof glass.
Description
The sheet method of closing that the present invention relates between two sheet glass, insert and put inorganic materials and make composite fireproof glass.
Flame resistant glass is a kind of glass deep processed product, has characteristics such as fire prevention, printing opacity, perspective, is widely used in aspects such as Highrise buildings, showpiece display, fire prevention partition.The general technology flow process of flame resistant glass production is: glass cutting, cast fire-resistant fluid, drying obtain the flame resistant glass veneer, close sheet, deburring again, and form flame resistant glass.The sheet that closes wherein is one critical process, is directly determining the final quality of product.Existing flame resistant glass closes the sheet method and adopts wet method to close sheet, promptly when two flame resistant glass veneers close sheet, by using complex liquid two glass veneers is bonded together, and forms flame resistant glass.And wet method is closed sheet following drawback is arranged:
1, makes the microvesicle that leaves very dense in the cementing layer, influence vision.
2, employed complex liquid is squeezed the back from the middle outflow of two veneers, pollutes the flame resistant glass outside surface, forms the bloom that is difficult to clean, and influences the visual appearance of finished product.
3, water content is too high in the cementing layer, easily comes unstuck, bubbles in the use afterwards, has shortened the work-ing life of product.
4, because complex liquid is clammy alkaline oily matter, wet method closes that the operations such as carrying of glass are subjected to certain influence in the sheet, is prone to slippage phenomenon.
The objective of the invention is to close the problem that chip technology exists, and provide a kind of dry method of composite fireproof glass to close the sheet method, thereby avoid wet method to close the defective that the sheet flame resistant glass brings at above-mentioned existing wet method.
For achieving the above object, the dry method that the invention provides a kind of composite fireproof glass is closed the sheet method, it uses single face to be installed with the flame resistant glass veneer of inorganic fire glue-line, and this method comprises the processing step of following order: 1. the glue layer with two flame resistant glass veneers is interlocked, perimeter alignment; 2. pack into and one be connected in the rubber bag of vacuum pump and vacuumize: keep poly-bag internal gas pressure 100-950Pa, continue 30-60 minute; Then, 3. use the 50-100 ℃ of dried heating chamber internal heating of warm air poly-bag 30-60 minute, continue to keep the bag internal pressure simultaneously; 4. stop heating, keep bag internal pressure and reduce to 40 ℃, close vacuum-pumping system to heating room temp; 5. reduce to room temperature, the deburring arrangement.
Originally closing the preference value of keeping the poly-bag internal gas pressure when sheet method vacuumizes is 100Pa, and the time length is 30 minutes.The hot air temperature preference value of dried heating chamber internal heating poly-bag is 95 ℃, and the time length is 30 minutes.
The present invention compared with prior art has following advantage:
1, glass non-closed and unilaterally do not polluted the glass surface cleaning.
2, eliminate wet method and closed the microvesicle that sheet brings, improved the quality of flame resistant glass product.
3, too high this defective of coming unglued that causes of water content in the cementing layer of having avoided causing because of the use complex liquid.
4, because there is not clammy complex liquid, the producer operates more convenient.
5, wired in flame resistant glass, folder net is convenient, and can reduce breakage rate, improves yield rate.
The dry method of this composite fireproof glass is closed the concrete implementation step of sheet method: 1. with drying good to be installed with the cleaning surfaces of the flame resistant glass veneer that the inorganic fire glue-line constitutes by single face clean; 2. with the unilateral upwards horizontal of closing of a veneer, the veneer that another piece is joined sleeve plate with it closes sheet and faces down and be buckled on the veneer that has placed, adjusts veneer relative position up and down, makes perimeter alignment and fixing; 3. adjusted is good veneer closes sheet packs into and is connected to vacuum pump and places rubber bag in the heating chamber, the sealing sack, and start vacuum pump and vacuumize: keep poly-bag internal gas pressure 100Pa, the time length is 30 minutes; 4. use 95 ℃ of warm air beating poly-bags, continue 30 minutes, continue to keep the bag internal pressure simultaneously; 5. stop heating, keep bag internal pressure and reduce to 40 ℃, close vacuum-pumping system to heating room temp; 6. reduce to room temperature naturally, open poly-bag, take out the flame resistant glass that gets togather, the deburring arrangement makes composite fireproof glass of the present invention.
Claims (3)
1, a kind of dry method of composite fireproof glass is closed the sheet method, uses single face to be installed with the flame resistant glass veneer of inorganic fire glue-line, and it is characterized in that: this method comprises the processing step of following order:
1. the glue layer with two flame resistant glass veneers is interlocked, perimeter alignment;
2. pack into and one be connected in the rubber bag of vacuum pump and vacuumize: keep poly-bag internal gas pressure 100-950Pa, continue 30-60 minute; Then,
3. use the 50-100 ℃ of dried heating chamber internal heating of warm air poly-bag 30-60 minute, continue to keep the bag internal pressure simultaneously;
4. stop heating, keep bag internal pressure and reduce to 40 ℃, close vacuum-pumping system to heating room temp;
5. reduce to room temperature, the deburring arrangement.
2, the dry method of composite fireproof glass according to claim 1 is closed the sheet method, it is characterized in that: keep poly-bag internal gas pressure 100Pa when vacuumizing, the time length is 30 minutes.
