Description
Technical field
The present invention relates to safety glass tempering technology field, the specially toughening method of 8-12mm 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 8-12mm, glass surface stress is uniform,
Flexibility, fragment, degree of the temper meet the requirements.
To achieve the above object, the present invention provides following technical scheme：The tempering side of 8-12mm safety glass
Method, comprises the following steps：
a：Glass horizontal is placed on roller-way, is sent in channel-type annealing furnace by roller-way, be heat-treated by interval；
First interval：260-350 DEG C of temperature, time 3-5 tri- minutes；Second interval：380-450 DEG C of temperature, time 4-6 points
Clock, 3rd interval：280-320 DEG C of temperature, time 3-4 minutes；4th is interval：550-600 DEG C of temperature, time 4-5 minutes；5th
It is interval：650-700 DEG C of temperature, time 5-7 minutes；
b：Using high pressure cold front heavy rain to 300-350 DEG C of glass surface temperature；
c：Heated 3-5 minutes in the potassium nitrate fused salt that glass is added 350-360 DEG C；
d：Glass is added in 150-160 DEG C of glycerine and is processed 4-6 minutes；
e：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.
