Description

The toughening method of 8-12mm safety glass
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.
Specific embodiment
Technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only It is a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill people The every other embodiment that member is obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Embodiment one,
The toughening method of 8-12mm safety glass, comprises the following steps:
a:8mm glass horizontals are placed on roller-way, are sent in channel-type annealing furnace by roller-way, hot place is carried out by interval Reason;
First interval:260-350 DEG C of temperature, 5 minutes time;Second interval:380-450 DEG C of temperature, 6 minutes time, the Three is interval:280-320 DEG C of temperature, 4 minutes time;4th is interval:550-600 DEG C of temperature, 5 minutes time;5th is interval:Temperature 650-700 DEG C, 7 minutes time;
b:Using high pressure cold front heavy rain to 300-350 DEG C of glass surface temperature;
c:Heated 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 6 minutes;
e:Room temperature is cooled to after taking-up.
The safety glass that will be processed is detected that its flexibility reaches 0.7 ‰, and fragment 58, meet in 50 × 50mm Standard;Degree of the temper=3.6N/cm, self-destruction rate 1 ‰ -3 ‰.
Embodiment two,
The toughening method of 8-12mm safety glass, comprises the following steps:
a:12mm glass horizontals are placed on roller-way, are sent in channel-type annealing furnace by roller-way, heat is carried out by interval Treatment;
First interval:260-350 DEG C of temperature, 5 minutes time;Second interval:380-450 DEG C of temperature, 6 minutes time, the Three is interval:280-320 DEG C of temperature, 4 minutes time;4th is interval:550-600 DEG C of temperature, 5 minutes time;5th is interval:Temperature 650-700 DEG C, 7 minutes time;
b:Using high pressure cold front heavy rain to 300-350 DEG C of glass surface temperature;
c:Heated 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 6 minutes;
e:Room temperature is cooled to after taking-up.
The safety glass that will be processed is detected that its flexibility reaches 0.6 ‰, and fragment 52, meet in 50 × 50mm Standard;Degree of the temper=3.4N/cm, self-destruction rate 1 ‰ -3 ‰.
