Many customers will meet some problems when you are processing the
laminated glass, here I conclude some situation for
laminated glass solution:
1 Bubble appeared on the edge of the laminated glass:
Problem: Stop vacuum pump and open the vacuum bag ealier, the air
come back to the glass again.
Solution: Please do not stop vacuuming and open the vacuum bag
until the temperature is below 50 degree( you can put your
hands on the vacuum bag to feel it( Body temperature is 36-37
degree).
2 Many small bubble appear in all around the glass. Vacuum or vacuum pump not able to get value not reached -0.095Mpa.
Solution:
1. Check for leaks, whether there is the case of the vacuum exhaust
pipe breakage.
2. Make sure the bag of silica glass display reasonable success
silicone vacuum bags can be clearly observed ,
silicone bags overall hardened glass shape highlight .
3. check the " airway " is blocked. surrounded by glass screen or
you can put some dry wood to glass (preferably
evacuated net ) and stomatal link to confirm linked together at the
glass and pores .
4. Check the size of the vacuum pump , the need for oil changes and other maintenance.
3. The glass is good after cooling, but after edging cracking or bubbles.
Solution: Such reasons are relatively small, when laminated wire glass
edging, will generate a lot of heat. Please edging wheel when the
magic loosen a bit, increase flushing water, allowed to cool
sufficiently to avoid excessively high temperatures lead to a lot
of grinding heat can not be caused by broken glass and release air
bubbles.
4. Laminated glass has a long strip of bubble.
The most common laminated glass bubble into a long strip-shaped
distribution, because glass surface irregularities, lack of film
thickness can not fill the gap caused by the curved glass, at the
bend on the formation of elongated bubbles.1, increasing the thickness of the film2, requires manufacturers of steel and steel pairing burn
5. Laminated glass bubbles in the drilling of the oftenIn the glass tempering process, the drilling of the often uneven.
Therefore, the general non perforated punch glass than the glass
flatness worse, please pay special attention to the flatness of the
punch at the glass when you want to select the punch.Please put both sides of the hole with heat tape snapping seal or
an appropriate increase in the middle of the film thickness.
