Description
Technical field
The present invention relates to a kind of processing technology of glass, more particularly, to a kind of system of high-strength refractory Cs-K glass
Standby technique.
Background technology
At present, flame resistant glass common on domestic and international market is mostly interlayer composite fireproof glass and wired flame resistant glass,
The refractory adhesive added in the former reforms into milky under ultraviolet irradiation and produces bubble quickly, has a strong impact on glass
Translucency, service life is shorter, and using manual operations and control, production efficiency underground, product quality is difficult to ensure that, it is impossible to entered
Row large-scale industrial production, and not only light transmittance is not good enough and heat can not be prevented to radiate for wired flame resistant glass, also there is peace
The problems such as pretending to be stupid heavy, limits the use as building exterior wall glass.In addition, also a kind of single-sheet fire-resistant glass, using spray
Coating carries out tempering to common float glass.
And the making of existing single-sheet fire-resistant glass, original is typically just used as using the material such as ordinary plate glass or safety glass
Piece, on the basis of these semifinished sheets, is polished, cleans and technological process and the method processing such as fire prevention processing, full
The performance requirement of sufficient flame resistant glass.The performance indications that the quality of its flame resistant glass is up to state standards, are mainly manifested in size inclined
In terms of difference, presentation quality, fire resistance, flexibility, light transmittance.The preparation method of existing flame resistant glass mainly exists glass
Heat, then cooled down in the presence of high-pressure blast air-flow, the preparation method has many drawbacks under hot environment, mainly
Intensity is not high, shock resistance and heat resistant fire-proof poor performance, significantly limit it and uses scope, therefore is badly in need of a kind of the anti-of high intensity
Flint glass.
The content of the invention
The purpose of the present invention is that there is provided a kind of preparation of high-strength refractory Cs-K glass for problem of the prior art
Technique, equipment goes out high intensity, shock resistance and the good flame resistant glass of heat resistant fire-proof performance.
In order to achieve the above object, the present invention is achieved through the following technical solutions：
A kind of preparation technology of high-strength refractory Cs-K glass, it is characterised in that comprise the following steps：
（1）It is prepared by fused salt：Sylvite and cesium salt are mixed, are put into fused salt groove, fused salt groove is heated to 400-500 DEG C, 6- is incubated
8h, is then reduced to 300-350 DEG C by fused salt groove again, adds additive, and stirring makes additive be sufficiently mixed with sylvite, cesium salt,
Then 400-500 DEG C is increased the temperature to, continues to stir, required fused salt is made；
（2）Chemical tempering：Monolithic glass is put into fused salt groove, ion exchange, glass are carried out under 400-500 DEG C of temperature conditionss
Sodium ion in glass causes vibration due to heating, thus complete in the less sodium ion of radius in surface layer of glass and fused salt radius compared with
The exchange of big potassium ion or cesium ion, realizes chemical tempering, is exchanged by sodium ion with the potassium ion or cesium ion in fused salt
Quantity increase, the compression of surface layer of glass is with enhancing；
（3）It is physical toughened：Glass after fused salt soaks is sent into special annealing furnace to be heated, heating room temperature is set
It is scheduled between 580-630 DEG C, the heat time, after the completion of heating, it is fast that glass enters cooling section by every millimeter of heating 35-45s of glass
Fast chilling；
（4）Air-cooled shaping:Glass after will be physical toughened take out and with 350-450mm/s speed feeding air grid carry out it is air-cooled into
Type, finally cooling obtains high-strength refractory Cs-K glass.
It is preferred that, the sylvite is more than one or both of potassium chloride, potassium nitrate, potassium sulfate and potassium phosphate.
It is preferred that, the cesium salt is cesium nitrate or cesium carbonate.
It is preferred that, the sylvite percentage by weight is the 48% of fused salt.
It is preferred that, the cesium salt percentage by weight is the 47% of fused salt.
It is preferred that, the additive includes the first additive and Second addition, wherein the first additive is aluminum oxide, oxygen
Change more than one or both of magnesium, zinc oxide, boron oxide and zirconium dioxide, Second addition be potassium phosphate, potassium metapbosphate,
It is more than one or both of potassium pyrophosphate and aluminum sodium phosphate.
It is preferred that, the first additive addition is the 2-4% of fused salt weight, and the Second addition addition is molten
The 1-3% of salt weight.
It is preferred that, the blast of glass edge is 650-670KPa in the air-cooled shaping, and the blast in centre is 610-
630KPa。
It is preferred that, the adjustment height of the air grid is between 30-80mm.
The present invention compared with prior art, with following beneficial effect：
（1）The flame resistant glasses made from step such as the present invention is prepared by fused salt, chemical tempering, physical toughened and air-cooled shaping are not only
With preferable fire protecting performance, while there is higher intensity and shock resistance, it is of the invention in the case of same thickness
Obtained strength of glass is 8-14 times of float glass, is 4-6 times of safety glass；
（2）Ion-exchange treatment, the sodium ion of glass surface are carried out in fused salt of the invention by the way that glass to be immersed to 400-500 DEG C
With the potassium ion in fused salt, cesium ion fast exchange, and by adding the first additive and Second addition in fused salt, enter one
Step accelerate ion-exchange speed, because potassium ion and cesium ion radius ratio sodium ion radius are much larger, the extruding of big ion and
Glass surface produces compression, makes glass-faced construction finer and close, due to caesium, the melange effect of potassium ion, glass surface shape
Into big many of the compression that exchanges than single ionic of compression, question response reaches again to enter glass after predetermined balanced degree
The physical toughened processing of row, is first heated at 580-630 DEG C, most glass surface is produced powerful compression through air-cooled shaping afterwards,
So as to greatly improve the intensity of glass；
（3）Glass machinability is good made from preparation technology of the present invention, can be processed into fireproof hollow glass, interlayer fire prevention glass
Glass, plated film flame resistant glass, arc flame resistant glass etc., application field are wide, can be used as indoor fire safety cut-off and passageway for fire apparatus etc..
