Carefully Use Insets for EVA Film Laminated Glass
Peter Lin
It is important to check clearly the surface of the intermediate
materials(inserts) used in producing decorative glass or strengthened
glass, such as non-woven cotton, chartaceous or plastic printing-work,
natural fabric, etc, because the surface of some intermediate
materials may have been coated or printed before, which may result in
adverse chemical reaction with Dry Melt adhesive EVA Interlayer Film
and consequently degrade the adhesion capacity of Dry Melt adhesive
EVA Interlayer Film.
That means not all the materials are suitable for lamination, and it's
very necessary to test Dry Melt adhesive EVA Interlayer Film quality
and effective time before use. Don't go to mass production blindly.
Meanwhile, it is suggested that those insets materials should get
dried before put into use so as to remove the moisture within them. It
has been proved that the laminated glass produced with moisture
intermediate materials will probably get bubble or de-lamination after
being stored for a period of time.
The laminated glass is processed and produced under the simultaneous
work of high temperature and pressure, so under certain temperature,
the solid Dry Melt adhesive EVA Interlayer Film will turn to fused
substance and may easily outflow the edge of the glass under pressure.
Because the edge is under the biggest pressure, the liquid film
outflows the glass most easily and thus will be thinner than inside.
After the Dry Melt adhesive EVA Interlayer Film get cooling and
contractive, it's probable that there is some bubble or de-lamination
around the glass edges. Considering this, we suggest customers use
some material to block the glass when laminating the glass, and the
material used to block the outflow of Dry Melt adhesive EVA Interlayer
Film should be higher than the glass thickness. In this way, it will
reduce the high pressure caused by the vacuum negative pressure on the
edge of glass, and thus reduce the outflow of liquid film.
We produce a toll called EVA film thermal cutter, which can be
electronic heated and can easily remove the remains of EVA Film around
edges of laminated glass.
