Delamination of Eva Interlayer Film Laminated Glass
By Peter Lin
DE-LAMINATION:
1-The heating temperature is not high enough or the heating time is not long enough for the (GLASS LAMINATING) EVA INTERLAYER FILM to melt and cross-link react totally, so the cross link reaction is not completely finished.
For this reason, please increase the heating temperature or prolong heating time of laminating.
2-The EVA INTERLAYER FILM (glass laminating) is out of the shelf life, most EVA INTERLAYER FILM (glass laminating)’s shelf life is about one year or longer. Please use the EVA INTERLAYER FILM (glass laminating) within the shelf life. Yes, different EVA INTERLAYER FILM (glass laminating) manufacturers may have different shelf life of the EVA INTERLAYER FILM (glass laminating).
3-Maybe it’s the problem of the quality of the EVA INTERLAYER FILM (glass laminating). Please do some small sample test, before your mass production.
4-The moisture of the glass or EVA INTERLAYER FILM (glass laminating) is too much. EVA INTERLAYER FILM (glass laminating) are less sensitive to moisture, compared to PVB FILM, but if the moisture is too high, it will do harm to the adhesion of EVA INTERLAYER FILM (glass laminating). Please dry glasses and store EVA INTERLAYER FILM (glass laminating) in good way.
5-There is some organic substance (Oil) on the surface of glasses. For example oily substance will also do harm to the adhesion of EVA INTERLAYER FILM (glass laminating).
Please clean the glasses if necessary. You can use clean water, industrial alcohol, Acetone to clean the glasses.
6-When laminated with the painted papers (like PP, PVC), the printing ink is too much and not being dried.
Please dry the printing papers first before laminating with glasses and EVA INTERLAYER FILM (glass laminating).
7-If you found the de-lamination is happening in the edges of the laminated glass, here is why: Maybe the workers touch the edges of the glasses with bare hands, and there are oily substance on the fingers, which will do harm to the adhesion of the EVA INTERLAYER FILM (glass laminating).Please ask your worker to wear gloves. Maybe its summer, and your worker work very hard, and their hands are sweaty. And the sweat will do harm to the EVA INTERLAYER FILM (glass laminating).
SELF-EXPOSIING:
1-The laminated glass is cooling too fast. Please do not open the oven door to help cooling after the temperature of the laminated glass is lower than 75 degrees.
2-Please avoid the hot laminated glass touching with the cold water.
3-Put some wood blocks between the laminated glasses to make the cooling is well-proportioned.
4-The quality of the glass is not good, which are easy to expose.
5-The EVA INTERLAYER FILM (glass laminating) is not eliminated the internal stress. Good quality EVA INTERLAYER FILM (glass laminating) will be eliminated the internal stress to make the EVA INTERLAYER FILM (glass laminating) less contracting.
If the EVA INTERLAYER FILM (glass laminating) are not eliminated the internal stress, then when laminating the glass with EVA INTERLAYER FILM (glass laminating), the EVA INTERLAYER FILM (glass laminating)’s internal stress would try to contract to its original state and cause the laminated glass to expose.
6-The silicon vacuum bag is not clean, which means maybe some block inside the silicon vacuum bag. So when the pre- laminated glass on the block and vacuuming is working, the pressure would break the laminated glass. So please clean the silicone vacuum bag before you lay down the pre-laminated glass.
