Abstract
The invention discloses a kind of tempered glass manufacturing methods, belong to tempered glass field.It includes preheating, quick to heat, cooling, then cools down, several steps such as natural cooling.By first being preheated before heating and in cooling stage using intermittent blowing mode, toughening degree is accurately controlled, so as to greatly reduce the self-destruction phenomenon in tempered glass process, yields is improved, reduces production cost.
Description
Technical field
The present invention relates to a kind of tempered glass manufacturing methods, belong to tempered glass field.
Background technology
Tempered glass is a kind of prestressed glass in fact, to improve the intensity of glass, usually using side chemically or physically
Method forms compression in glass surface, and glass bears to offset skin stress first during external force, so as to improve bearing capacity, increases
Strong glass itself anti-wind pressure, cold and heat, impact etc.., it is necessary to will be general during Physical manufacture tempered glass be used
Logical glass is warming up to tempering temperature, then rapid cooling, forms prestressing force.But glass heating is too fast, easy uneven heating is led
Glass quality is caused to decline；In addition, during rapid cooling forms prestressing force, self-destruction is easily generated, this is because prestressing force shape
Into the bad control of size, prestressing force is bigger, and toughening degree is higher, and self-destruction rate is also higher, causes yield rate low, additional to increase production
Cost.
The content of the invention
The technical problems to be solved by the invention are：A kind of tempered glass processing technology is provided, it is further avoided
Tempered glass generates the phenomenon that self-destruction in the fabrication process.
The technical problems to be solved by the invention are adopted the technical scheme that：A kind of tempered glass processing technology, it is wrapped
Include following steps：
A. preheat, glass is positioned in annealing furnace, start to be slowly heated, the temperature of glass is made gradually to be warming up to by room temperature
120-150 DEG C, whole process continues 150-180 seconds；
B. quick heating, by the temperature fast lifting of glass to 600-650 DEG C, and is kept for 300-360 seconds；
C. cool down, glass is moved into air grid by annealing furnace in 1.5-2 seconds, start intermittent blowing, dry 1-5 seconds, stop
Only 1-2 seconds, whole process continued 30-40 seconds, and glass temperature is down to 480-500 DEG C；
C. cool down again, persistently dry 160-200 seconds, glass temperature is down to 45-50 DEG C；
D. natural cooling is taken out glass, cooled to room temperature from air grid.
The beneficial effects of the invention are as follows：By first being preheated before heating and in cooling stage using interval
Property blowing mode, accurately control toughening degree, so as to greatly reduce the self-destruction phenomenon in tempered glass process, improve
Yields reduces production cost.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the present invention are easy to understand, it is expanded on further
The present invention：
