Embodiment Construction
[0027] The processing technology of this toughened glass comprises the following steps:
[0028] a. Heating, place the glass in a tempering furnace and heat it until the temperature of the glass reaches 630-650 degrees, and the heating time is 7-8 minutes; a1, the first heat preservation, keep the heated glass at a temperature of 630-650 3-5 minutes;
[0029] b. Cooling, quickly put the heated glass on the air grid for rapid cooling until the temperature drops to 300-320 degrees, and the cooling time is 10-15 seconds; b1, the second heat preservation, maintain the rapidly cooled glass at the temperature 3-5 minutes at 300-320 degrees.
[0030] c. Slow heating, slowly heating the cooled glass at a temperature of 3-5 degrees per minute, heating to 480-490 degrees, and maintaining the temperature for 10-20 minutes;
[0031] d. Slow cooling, slowly cooling the slowly cooled glass at a temperature of 2-3 degrees per minute, cooling to 378-400 degrees, and maintaining the temperat...
