Condition:
Small bubbles at the edges of safety laminated glass with Polyvinyl Butyral PVB interlayer film.

Reason: 1)
When the autoclave decreasing the pressure, although the temperature detector shows the temperature is under 50 degree Celsius, due to the glass thickness and square, sometimes, the glass temperature is still higher than 50 degree Celsius, so if the pressure is lowering, some air will absorbed into the glass edges.

Solution:
Even when the temperature detector shows the temperature is lower than  50 degree, don’t decrease the pressure too hurry, wait for some minutes, make sure the real temperature of the glass is lower than 50 degree. If the laminated glass is thick, or many layers, or large square, then the waiting time should be a little longer.

Reason:2)
The tempered glass is not high quality enough, and the plainness of the tempered glass is not good enough.

Solution:
Choose better quality tempered glass, or use the thicker Polyvinyl Butyral PVB interlayer film.

Reason:3)
Maybe the detector of the temperature and pressure is not correct.

Solution:
Make sure the temperature and pressure parameters is correct .
