Abstract
The invention discloses a method for toughening a piece of 12mm toughened glass. The method comprises the following steps of horizontally placing the glass to be processed onto a roller bed, delivering the glass to be processed into a passage type toughening furnace through the roller bed, sequentially conducting heat treatment at intervals, and cooling two surfaces of the glass through high-pressure air until the surface temperature of the glass reaches 330 to 350 DEG C; placing the glass into 10 to 15 percent potassium nitrate glycerol solution at the temperature of 150 to 160 DEG C to be cooled for 3 to 4 minutes; then placing the glass into the potassium nitrate fused salt at the temperature of 350 to 360 DEG C to be heated for 5 to 6 minutes; and taking out the glass to be naturally cooled in the air. Through the interval heating and cold treatment, the stress distribution on the surface of the glass is adjusted, and the flatness of the toughened glass is guaranteed; and through the treatment in the potassium nitrate glycerol solution and the potassium nitrate fused salt, the toughened degree of the glass surface is increased, the self cracking possibility of the glass in the cooling process can be reduced, the yield of finished products of the toughened glass can be increased, and the performance index requirement of the toughened glass can be met.
Description
Technical field
The invention belongs to the glass preparation field, be specifically related to the preparation technology of toughened glass.
Technical background
Toughened glass makes it be widely used owing to have higher mechanical strength, good heatproof acute degeneration, good advantages such as security.It is the steel process of heat-eliminating medium that existing toughened glass production process adopts mostly with the air, makes to be heated glass and to carry out Quench at short notice by a large amount of air and handle, thereby finishes the tempering process.In order to guarantee the performance of toughened glass, the air of very big flow need be provided in very short time usually, especially more obvious when tempering approaches glass, select for use the high-power blower of high blast, big flow to dry simultaneously usually.
At present the mode of glass tempering also has the chemical tempering mode, and chemically toughened glass intensity and physical toughened glass are approaching, but overlong time, the low and production cost height of efficient.
Summary of the invention
The tempering processing method that the purpose of this invention is to provide a kind of 12.0mm toughened glass, glass surface stress are evenly, sinuousness, fragment, degree of the temper all meet the requirements.
Technical solution of the present invention is as follows:
12.0mm the tempering processing method of toughened glass is characterized in that may further comprise the steps:
(1), with bath of glass placing flat to be processed to roller-way, deliver in the channel-type annealing furnace by roller-way, heat-treat successively by the interval:
First interval: temperature 280-350 ℃, time 3-5 minute; Second interval: temperature 420-450 ℃, time 4-6 minute; The 3rd interval: temperature 350-380 ℃, 2-3 minute; The 4th interval: temperature 550-600 ℃, time 4-5 minute; The 5th interval: temperature 650-700 ℃, time 5-7 minute;
(2), adopt double-sided glass to carry out high-pressure blast and be cooled to 330-350 ℃ of glass surface temperature;
(3), the saltpetre glycerine solution that glass is added 150-160 ℃ 10-15% cooled off 3-4 minute;
(4), again join in the 350-360 ℃ of saltpetre fused salt, heated 5-6 minute;
(5), take out back air naturally cooling.
The present invention is by adopting by stages heating, deepfreeze, regulate the glass surface stress distribution, guaranteed the planeness of toughened glass, handle by saltpetre glycerine solution and saltpetre fused salt, increased the degree of the temper of glass surface, reduce the probability that glass is revealed in process of cooling, improved the yield rate of toughened glass, satisfied the performance index requirement of toughened glass.
Embodiment
12.0mm the tempering processing method of toughened glass may further comprise the steps:
(1), just the bath of glass placing flat is delivered in the channel-type annealing furnace by roller-way to roller-way, heat-treat successively by the interval:
First interval: temperature 320-340 ℃, time 4-5 minute; Second interval: temperature 420-430 ℃, time 4-6 minute; The 3rd interval: temperature 350-380 ℃, 2-3 minute; The 4th interval: temperature 560-600 ℃, time 4-5 minute; The 5th interval: temperature 680-700 ℃, time 5-7 minute;
(2), adopt double-sided glass to carry out high-pressure blast and be cooled to 330-350 ℃ of glass surface temperature;
(3), 15% the saltpetre glycerine solution cooling 4 minutes that glass is added 150-160 ℃;
(4), again glass is joined in the 350-360 ℃ of saltpetre fused salt, heated 5-6 minute;
(5), glass takes out back air naturally cooling.
The toughened glass that processes is detected, and its sinuousness reaches 0.6 ‰, 52 of 50 * 50mm internal fragments, conformance with standard; Degree of the temper=3.4N/cm, the self-destruction rate is 1 ~ 3 ‰.
Claims (1)
1.12.0mm the tempering processing method of toughened glass is characterized in that may further comprise the steps:
