Description
Technical field
The present invention relates to safety glass tempering technology field, the specially toughening method of 3-6mm safety glass.
Background technology
Safety glass makes due to having the advantages that mechanical strength higher, good heatproof acute degeneration, good security
It is widely used, and existing safety glass production process uses the steel process with air as cooling medium mostly, makes
Be heated glass carries out Quench treatment in a short time by above the average age for marriage cold air, so as to complete toughening process.In order to ensure tempering
The performance of glass, it usually needs the air of very big flow is provided within a very short time, it is especially more bright in the relatively thin glass of tempering
It is aobvious, generally dried simultaneously using the high-power blower of blast high, big flow.The mode of current glass tempering, chemically toughened glass
Intensity is close with physical toughened glass, but overlong time, and efficiency is low and production cost is high.
The content of the invention
It is an object of the invention to provide a kind of toughening method of the safety glass of 3-6mm, glass surface stress is uniform, curved
Curvature, fragment, degree of the temper meet the requirements.
To achieve the above object, the present invention provides following technical scheme：The toughening method of 3-6mm safety glass,
Comprise the following steps：
a：Plate glass is put into 100 DEG C of saline solutions of boiling, the concentration of saline solution is 15-18%；
b：Glass horizontal is placed on roller-way, is sent in channel-type annealing furnace by roller-way, be heat-treated by interval；
First interval：220-260 DEG C of temperature, time 2-3 minutes；Second interval：380-420 DEG C of temperature, time 4-5 points
Clock, 3rd interval：280-320 DEG C of temperature, time 3-4 minutes；4th is interval：520-580 DEG C of temperature, time 4-5 minutes；5th
It is interval：650-700 DEG C of temperature, time 5-6 minutes；
c：Using high pressure cold front heavy rain to 300-350 DEG C of glass surface temperature；
d：The potassium nitrate glycerite that glass adds 150-160/12-15% is cooled down 3-5 minutes；
e：Glass is added in 200-210 glycerine and is processed 4-6 minutes；
f：Room temperature is cooled to after taking-up.
The present invention using by stages heating, cold treatment, adjust glass surface stress distribution, it is ensured that safety glass it is smooth
Degree, by potassium nitrate glycerite, hot water treatment, increased the degree of the temper of glass surface, reduce glass in cooling procedure
Self-destruction probability, improve the yield rate of safety glass, meet the performance requirement of safety glass.
