Piece is heated to 280 DEG C -300 DEG C, and keeps the temperature the 120-150min that holds time, after heat preservation, the tempered glass piece is slow
It is cooled to room temperature；
Step 8: PVB film is sandwiched in two after the tempered glass piece is re-started cutting, cleaning, drying by the doubling stage
Doubling glass piece is formed between tempered glass piece described in piece, then crops the extra part of the PVB film, when cutting, institute
The PVB film surplus on the outside of doubling glass piece is stated in 2-5mm range；
Step 9: the good doubling glass piece of doubling is sent in roll squeezer by conveyer belt and is carried out by roll-in softening stress-displacement stage
Roll-in, exhaust, edge sealing are heated, the good doubling glass piece of roll-in is then loaded into glass frame, and add elastic clip, it will be described
Doubling glass piece fixes；
Step 10: the doubling glass piece fixed is transmitted into autoclave, makes the doubling glass by autoclave shaping stage
Piece forms the toughened interlayer glass of high quality under the effect of prolonged high temperature and pressure, and is fabricated to finished product.
The sheet glass uses ordinary plate glass or float glass, and the high quality common plate glass requires special product
Or Grade A, the float glass require to use high-class product or primes.
The glass sheet thickness uses 5-15mm.
The PVB film uses polyvinyl butyral film piece, and the PVB film stock thickness uses 0.76-2.88mm.
The doubling stage carries out in doubling room, and the doubling Cleanliness should be purified to 100,000 grades, the doubling
Room temperature is set as 23 DEG C -27 DEG C, and relative humidity is set as 22%-28%.
Beneficial effects of the present invention: toughened interlayer glass, energy is made in reprocessing after tempered glass is made by the above method
It is enough effectively to enhance its crushing resistance, and its intensity can be enhanced.
