Bubbles of Ethylene Vinyl Acetate EVA Film Laminated Glass

Bubbles of Ethylene Vinyl Acetate EVA Film Laminated Glass

Reason 1:
The plainness of the glass is not good. If you making tempered
laminated glass, make sure the thickness of Ethylene Vinyl Acetate EVA
film is thick enough.

Reason 2:
The Ethylene Vinyl Acetate EVA film is not melt completely when
processing in the laminating vacuum oven, you need to increase the
temperature or prolong the heating time to make sure Ethylene Vinyl
Acetate EVA Film is melt completely.

Reason 3:
Stop vacuuming too early. Make sure you keep vacuuming always working
in whole procedure of making laminated glass, and only stop the
vacuuming after the temperature is lower than 45 degree C.

Reason 4:
The silicone bag is leaking, so the vacuuming pressure can not reach 0.095MPA.

Reason 5:
Moisture in the surface of glass, Ethylene Vinyl Acetate EVA Film,
decorative interlayers is too much, please dry them before laminating.

Reason 6:
Part of laminated glass is suffering too high temperature, and lead to
the Ethylene Vinyl Acetate EVA Film decompose to gas. Make sure the
heating is well-distributed. And make sure the temperature detector is
working well and get the correct temperature.

Reason 7:
When edging laminated glass, bubbles appear at the edges. Because
edging makes heat, and too much heat causes the bubbles. Please use
more water to cool laminated glass when edging, and edging slowly and
softly if necessary.

Any other situation, please feel free to contact us.
