+ Solar control- The smart glass is in processed in the same way of the laminated glass with advanced Ethylene-vinyl acetate EVA Interlayer Film.

Advantages of Smart Glass Privacy Glass

+ Fast switching reaction. The switching can be finished in 0.1 Second.
+Safety—The Smart glass is processed in the safety laminated glass
way, owning the safety properties like the laminated glass made of
Ethylene-vinyl acetate EVA Interlayer Film . When the smart glass is
impacted, the glass broken pieces is sticked on the Ethylene-vinyl
acetate EVA Interlayer Film, and will not drop or fly to hurting
people.

+ Saving electricity power -When you need privacy, you turn off the
power, the smart glass is frosted, at this sate, the people outside
the smart glass can not see through.

+ Solar control- The smart glass is in processed in the same way of
the laminated glass with advanced Ethylene-vinyl acetate EVA
Interlayer Film. So the smart glass con blocked 99% UV RADIATIONS.
Which can protect the people and goods inside the room from the UV
RADIATIONS.

+ Sound control- The smart glass is laminated with high advanced
Ethylene-vinyl acetate EVA Interlayer Film, the Ethylene-vinyl
acetate EVA Interlayer Film owns the properties of sound insulation.
So the smart glass can reduce about 38 db of the noise outside.

+ Use for projection- When the smart glass in privacy sate, the Degree
of scattering is more than 43% and the light transmission is more than
50%. So the projection can be implied and the view effect is great.

Important Safe Notes of Operating EVA Vacuum Glass Laminating Machinery
By ZAC GLASS www.helloglass.com

When operating EVA Vacuum Glass Laminating Machine, please pay
attention to these safety notes:
(1)
The EVA Vacuum Glass Laminating Machine must be installed at dry
plain floor with good ventilation. But avoid strong sunlight radiation
and rain or moisture.

(2)
Don’t put or cover anything on the machine, and don’t jam the exhaust
outlet and Motor.

(3)
If the EVA Vacuum Glass Laminating Machine is at high temperature,
don’t open the door of a running EVA Vacuum Glass Laminating Machine.

(4)
Carefully push and pull the vacuum shelf. Because if the shelf breaks,
it will harm people.

(5)
Make sure the temperature is below 40℃ when take out the laminated EVA
glass from the silicone vacuuming bag.

so the smart glass film(switchable glass film, privacy glass film) may be decompound by the acid and basicity in the air.

Storage of Smart Glass Film(switchable glass film, privacy glass film)

When in long time storage of smart glass film(switchable glass film,
privacy glass film)
, because the smart glass film is made of liquid crystal and polymer,
so the smart glass film(switchable glass film, privacy glass film)
may be decompound by the acid and basicity in the air.

But CNC INTERLAYER TECH use the highest purity of crystal to avoid
decompounding.

But anyway, if you don’t use the smart glass film(especially the
non-adhesive smart glass film), please repack it in sealed condition.

Moisture in the glass surface or Ethylene Vinyl Acetate EVA Film or environment is too much. Please dry it before lamination.

Delamination of Ethylene Vinyl Acetate EVA Laminated Glass

By Peter Shin www.helloglass.com

Reason one:
The heating temperature or time is not enough. Please consult about
processing instruction with Ethylene Vinyl Acetate EVA Film
manufacturer.

Reason two:
Ethylene Vinyl Acetate EVA Film is out of self-life, please use
Ethylene Vinyl Acetate EVA Film before expiration. Please confirm with
Ethylene Vinyl Acetate EVA Film manufacturer how long the self-life
is.

Reason three:
The glass surface is not clean, maybe you use some organic water to
wash the glass, make sure the glass surface is clean and dry.

Reason four:
Moisture in the glass surface or Ethylene Vinyl Acetate EVA Film or
environment is too much. Please dry it before lamination. Or prolong
the low-temperature heating time.

Reason five:
If the lamination takes place in some part of laminated glass, maybe
it due to the sweat on the hand of worker, please make sure the worker
is wearing gloves.

Any other situation, please feel free to contact us.

+Third step, decide whether you want to cut the size your want so you order the standard size smart film from suppliers,

Steps of Purchase Smart Glass Film
+First step, decide what kind of smart glass you are going to make: to
install safety smart glass in the building, or make the installed
windows smart. By doing this, you can know whether you need the
non-adhesive smart film or self-adhesive smart film. If you need
non-adhesive smart film, make you sure you have the laminating tools
and machine.

+Second step, decide size of the smart glass film and the quantity fo
smart glass film.
+Third step, decide whether you want to cut the size your want so you
order the standard size smart film from suppliers, or you want order
the correct specification you need from the supplier, meaning the
suppliers will cut just the size of smart film you need.
+ Four step, choose type of smart film suits you.
+Five step, Confirm whether you need the smart film supplier to
install the bus-bar for you and offer the power device.

The answer is no. So then what is the real why? Because the Switchable Transparent Film itself is a laminated Film.

Why Switchable Film Break When Laminating with Glass and EVA Interlayer Film？

Wrong Concept:
Some customers made the Smart Glass with EVA Interlayer Film, and the
Switchable Transparent Film break away it self, so he asks EVA
Interlayer Film Manufacturers whether the EVA Interlayer Film produce
some chemical substance that cause the Switchable Transparent Film
breaking away itself?

Composition Of Switchable Film:
The answer is no. So then what is the real why? Because the Switchable
Transparent Film itself is a laminated Film.
Composition of Switchable Transparent Film:

The polymer and the liquid crystals are encapsulated in the Switchable
Transparent Film. Both faces of the film are covered with a
transparent, ITO coating. Both ITO coatings are connected to a flat
electrical busbar, which is fixed on one of the edges of the film.

Reason Why Switchable Film Delamination
When the Switchable Transparent Laminated Glass(Glass+EVA
Film+Switchable Film+EVA Film+Glass) is being heated and then cooled,
the EVA Interlayer Film, Glass and Switchable Transparent Film will
follow the Expand from Heat and Contract from Cold rule.

But Switchable Transparent Film is WEAKER in the Expand from Heat and
Contract from Cold than the EVA Interlayer Film. And also the adhesive
strength between the EVA Interlayer Film and Switchable Transparent
Film is harder than the adhesive strength between the layers inside
the Switchable Transparent Film itself. And the adhesive strength
between the EVA Interlayer Film and glasses is harder than the
adhesive strength between the layers inside the Switchable Transparent
Film itself. That’s the reason why the Switchable Transparent Film
Break away When Laminating with Glass and EVA Interlayer Film，It’s the
EVA Film Shrinkage that break away the Switchable Film.

How to Solve:
1.Find a better supplier of EVA Film, whose EVA Film is less in Shrinkage rate.
2. Some EVA Interlayer Film Manufacturers have made the
low-temperature (about 80-85 degree) processing EVA Interlayer Film
dedicated for making Switchable Transparent Laminated Glass.
With using the low-temperature-processing EVA Interlayer Film, you can
solve this problem.
