Self-breaking Quality of glass is bad Purchase from good quality
glass supplier
When cooling, not well-distributed heat Separate laminated glass by
wooden bar for cooling well-distributed
Not super clear enough Heating temperature is not high
enough Increasing the heating temperature to high enough as EVA Film
manufacturer suggests
Adhesive strength is not strong enough Too many layers of laminated
glass process in one silicone bag at a time Prolong the
high-temperature heating time
Reduce the layers of laminated glass in one silicone bag at a time

Any other situation, please feel free to contact us.

+Glass Industrial Autoclaves are pressure vessels used to process
glasses and polymer materials which require exposure to elevated
pressure and temperature. The manufacture of high-performance
components from advanced composites often requires autoclave
processing.

+Vacuum
Parts processed in an autoclave are often silicone vacuum bagged to
enable the pressure to operate isostatically on the workpieces. In
simplest form, the workload is fully contained inside a loosely
fitting silicone bag made of resilient plastic capable of withstanding
the temperatures involved. When vacuum is drawn, the bag is compressed
by atmospheric pressure and compacts the components inside. Between
the parts and the bag, an absorbent material provides a channel for
the evacuation of the air and wicks up the excess resin squeezed out
during curing.

+In autoclave processing of composite parts, the SILICONE vacuum bag
functionality may be where the greatest variety may be found. Some
manufacturers will leave the bag under full vacuum from lay-up to
post-cure tear-down. Others will hold the silicone vacuum bag only
until the autoclave reaches full pressure. Yet others will back-fill
the silicone vacuum bag with inert gas, typically nitrogen, at zero
pressure.The role played by the silicone vacuum bag’s internal
pressure can be critical in the consistent production of high-quality
PVB Laminated Glass.

+Polyvinyl butyral (or PVB) is a resin often adopted for applications
that require strong binding, optical clarity, adhesion to many
surfaces(organic or non organic sheets), toughness, great tensile
strength and flexibility. It is prepared from polyvinyl alcohol by
reaction with butyraldehyde. The major application is laminated safety
glass for automobile windshields. Tradenames for PVB-films include
GlasNovations, Butacite, Saflex, S-Lec, CNCnext and Trosifol.

+Laminated glass is a type of safety glass that holds together when
shattered. In the event of breaking, it is held in place by an strong
polymer interlayer, typically of polyvinyl butyral (PVB) or EVA Film,
between its two or more layers of glass. The PVB interlayer keeps the
layers of glass bonded even when broken, and The high strength of
cross-linked PVB interlayer prevents the glass from breaking up into
large sharp pieces. This produces a characteristic “spider web”
cracking pattern when the impact is not enough to completely pierce
the laminated glass.

+There are several laminated glass manufacturing processes:
-using two or more pieces of glass bonded between one or more pieces
of plasticized polyvinyl butyric resin using heat and pressure .
-using two or more pieces of glass and polycarbonate, bonded together
with aliphatic urethane interlayers under heat and pressure.
-interlaid with a cured resin.
Each manufacturing process may include glass lites of equal or unequal
thickness.

[Silicone Bag for making bent laminated glass with PVB Film]

+Bent Laminated Glass:
When making Bent laminated glass with Polyvinyl Butyral PVB film, like
car windshield glass, car windows etc, you will need silicone bag for
vacuuming. Bent and curved glass is often used for automotive glass
and marine glass installations.

LAMINATED GLASS STNADS STRONGLY IN SANDY HURRICANGE
www.helloglass.com WWW.EVAFILMS.COM
Peter Shin

The SANDY hurricane attacked New York city.
It’s a big news. And many Chinese people talked a lot of it in SINA WEIBO.COM
One photo is welcomely retweeted in China twitter: SINA WEIBO.COM
The photo is a glass door that hold back the water outside to prevent
the water come in to room.
The photo of laminated glass is here:

The photos of laminated glass tell us that, the laminated glass door
is very strong to hold so much water pressure. Second, the door
sealing is very good.

Some tweets of the laminated glass are:
Can China glass manufacturers produce such strong glass?
Why does the glass not break?
Is this laminated glass made in China?

Some guess, the laminated glass is PVB laminated glass, made of Dupont
SGP PVB interlayer.
China now have many manufacturer of PVB INTERLAYER FILM and EVA
interlayer film for laminated glass.
To produce the world-class one laminated glass for hurricane, there is
still a long way ahead.
There are many progress of modification of properties of PVB
interlayer film/ EVA interlayer film made, but there should be more
innovative progress in the future.

Why the Transparence is Bad After Installation Smart Glass Film
www.HelloGlass.com

The reason may be the busbar installation is not very good. The touch
of the copper bar is not very good with smart glass film ITO layer. So
the electric resistance is is high.
So the voltage of the smart glass film is lower than we expect, and if
the voltage is not high enough for the smart glass film, the
transparence of smart glass film will be reduced.
So you better carefully restore the busbar of smart glass film to make
sure the copper bar connect well with Smart glass film ITO.

www.HelloGlass.com

The cost of use LED is higher than SMART GLASS FILM projection.
SMART GLASS FILM projection is better at energy saving (consume less
electricity).
The view angle range of SMART GLASS FILM projection is wider than LED screen.

Frequently Asked Question of Privacy Glass Film(PDLC Film, SPD Film,
Magic Glass Film)

www.HelloGlass.com

-What is SPD smart glass film?
+Smart glass film is a combination of liquid crystal , polymer, ito and PET.
When the power is off, the liquid crystal molecules is irregular, and
shatter the light, so the smart glass film is frosted white.
When power is on, the liquid crystal molecules is in line, and let the
light pass through, so the smart glass film is transparent.

-Where can i use smart glass film?
+The smart glass film can be used in many ways, include:
Architectural windows, doors, skylights and partitions
Car sunroofs, side and rear windows, visors, mirrors
Appliance windows
Other vehicle windows, doors, hatches and partitions
Advertising signage and displays and light filters.

-What are advantages of smart glass film produced by CNC?
+CNC-Smart glass film have many unique advantages, including:
Shortest time to control of light, glare and heat manually or automatically
Good UV protection
Longest durability
Low haze when power on
Wonderful energy saving
Good sound insulation

-How to order smart glass film?
+If you are new, you can tell us the exact size you need, which side
to make busbar, then will prepare the smart glass film with all the
tools you need for you.
If you are experienced, you can order the standard size of smart glass
film from us and cut the size by yourself and make busbar on your own.
