3) according to the thickness of synthetic glass, mix up the roll-in spacing, the subregion design temperature is 127 ℃ ± 7.5 ℃ in a district, 210 ℃ ± 10 ℃ in two districts, 230 ℃ ± 10 ℃ in three districts;
4) glass surface is sideling 15 °-45° angle and puts and send in the roll squeezer, after a district that step 3) sets, the He San district roll-in of two districts, make finished product through HTHP again.
Preferably, purify electrical conductivity of water in the step 1) less than 8us/cm.
Preferably, purifying electrical conductivity of water in the step 1) is 5us/cm.
Preferably, step 2) temperature that the sheet chamber is closed in the purification in is 23 ℃, and humidity is 30%.
Preferably, step 2) temperature that the sheet chamber is closed in the purification in is 25 ℃, and humidity is 35%.
Preferably, step 3) Zhong Yi district temperature is 127 ℃, and two district's temperature are 210 ℃, and three district's temperature are 230 ℃.
Preferably, step 3) Zhong Yi district temperature is 134 ℃, and two district's temperature are 220 ℃, and three district's temperature are 240 ℃.
Preferably, step 3) Zhong Yi district temperature is 120 ℃, and two district's temperature are 200 ℃, and three district's temperature are 220 ℃.
Preferably, the angle of inclination of glass surface is 30 ° in the step 4).
Beneficial effect of the present invention:
1, adopts electrical conductivity less than the cleaning glass of purifying waste water of 8us/cm, use hot blast drying, reduce the glass surface plasma residual, improve the bonding force of glass and diaphragm.
2, control purifies and to close the indoor humiture of sheet, 23 ℃ ± 2 ℃ of normal temperatures, and standard humidity≤35% carries out constant temperature dehumidification before closing sheet, and the standard that reaches is synthesized again, but the steam between emptying glass and diaphragm and air improve bonding force.
3, according to thickness of glass, set temperature between precompressed zone, be set as 127 ℃ ± 7.5 ℃ in a district, 210 ℃ ± 10 ℃ in two districts, 230 ℃ ± 10 ℃ in three districts make glass emptying air in roll-in, and along with the rising of interval temperature, reaching is bonded together fully is transparence.
The glass surface that 4, will enter roll squeezer becomes 30 ° of angle swings to put sideling.Can avoid glass dislocation and further with Bas Discharged.
