lamination

1, film room:The temperature of the film room is controlled at 20-25℃, the humidity is kept at 23% soil 2%, the room is kept dust-free, and the mechanical equipment is kept clean. The staff need to keep the uniforms, hats and gloves clean to prevent the adhesion of dust, impurities and hair.

2, combined film conditions:The glass surface temperature is recommended to be controlled at 20-30 ° C and the maximum temperature should not exceed 40 ° C. The film surface temperature is recommended to be controlled between 20-25 ° C. Double check that the film and glass are clean, and that the glass and film are all placed together.

预压排气

Precompressed exhaust

1, cold pumping and hot pumping

1.1, cold pumping: temperature 20-25℃, pressure -0.095--0.1Mpa. The continuous vacuuming time is about 20 minutes. If the vacuum is not continuous, the cold vacuuming time is about 30 minutes.

1.2, hot pumping: glass surface temperature 100-120° C, time 30-45 minutes, pressure between -0.095- 0.1Mpa. Remove the glass when the temperature drops to 45-60°C.

2, pre-pressure exhaust

2.1, incubator preheating → laminated glass surface temperature 20-30 ° C, humidity about 25% → Zone 1 incubator 100-120 ° C, the first prepressing, the pressure is 0.2-0.5Mpa, the roll distance is less than the total thickness of glass about 1mm → Zone 2 incubator 160-180°→ Zone 3 incubator 220-240 ° C→ second roll pressing, The pressure is 0.3-0.5MPa, and the roll distance is less than about 2mm of the total thickness of the glass.

2.2, maintain continuous operation to maintain the temperature of the thermostat.

High pressure forming

The whole process should be slowly heated and pressurized or cooled and decompressed, the following process for reference: Temperature rise and pressure → temperature rise to 60℃, pressure 0.4Mpa→ temperature rise to 90℃, pressure rise to 0.8Mpa→ temperature rise to 120-130° C, pressure rise to 1.0Mpa→ pressure rise to 1.1-1.3Mpa→ constant temperature 30-60 minutes (according to the thickness and quantity of glass in the kettle)→ constant pressure cooling, Automatic slow cooling to 90℃→ then cooling to 45-55℃ exhaust.
