What is the smart pdlc percentage of transmission in transparent mode?
Technological developments in the smart pdlc industry do not stop. Glass technology has formed a serious scientific and technical track in recent years and continues to surprise us day by day. This time, it appears as privacy smart glass as a decorative and aesthetic material whose opacity can be adjusted using electrical energy.
How does smart pdlc work?
Smart Glasses use electro-chromatic technology to switch between a transparent and an opaque state by applying voltage. Moreover, it allows the lights to pass through both sides while changing from light colors to a frozen look in one flick. Hence, it is just like in the two photos above.
To mention the working principle and the structure of the material;
We can consider smart pdlc like glass types that gets shape of curvy or flat. While applying this method, it should be very sensitive and sensitive. Manufacturers make it by placing liquid crystals between two conductive films.
PDLC technology and AFS Smart Window films
PDLC class window films are smart materials that have a transparent appearance when electric current is applied and an opaque / frosted glass appearance when the electric current is cut. The liquid crystal droplets contained in its structure enable the PDLC optical properties to be controlled by electric current. Furthermore, PDLC films are in a sandwich structure.
This structure consists of a highly transparent polymer layer with liquid crystal droplets placed between two transparent conductive layers (ITO-PET film). When electric current comes to ITO-PET films, the liquid crystals go in one direction and allow the incoming light to pass. When the electric current is cut, the liquid crystals are randomly oriented and scatter the passing light.
PDLC smart films, the first examples of which met with its users in the 1990s, have continuously improved in parallel with material technologies. Smart pdlc is a member of the new generation PDLC class compared with their counterparts around the world. Hence, it is a product that exhibits superior performance.
It is among the best in its class with its high:
- optical transmittance
- viewing angle
- improved moisture and
- UV resistance.
Wglass continues to continuously improve the properties of the PDLC films it produces with its R&D studies.
Usage Areas of smart pdlc Based Smart Glasses
Architectural glasses are the main use of PDLC smart films. Subsequently, the most common application in this area is modern glass office partitions. CEO, executive rooms and meeting rooms gain a stylish and spacious structure with glass partitions.
Traditionally, we use blinds in these glass panes to protect privacy. Blind systems have many disadvantages such as offering a segmented appearance even when open and mechanical problems in opening-closing mechanisms.
Generally, smart pdlc films offer a solution far beyond being an alternative to blinds. Unlike blinds, we can turn PDLC smart glasses into frosted glass within milliseconds by cutting off the electric current. Hence, we can protect the privacy.
How smart pdlc is good for commercial projects?
Apart from office applications, it acts as a curtain in:
- exterior windows
- in hotel rooms
- bathroom partitions
- toilet cabins
Smart glass systems are common in:
- control rooms and industrial facilities
- research laboratories
- security compartments and passport counters
- sports facilities
- saunas and swimming pools
- luxury home and residence concepts.
Another area of use is medical facilities. Similarly, it is also good for compartments that require privacy at different times. Hence, it includes:
- MRI and X-ray tomography rooms
- neonatal and intensive care units
- chemotherapy departments and patient rooms
Production and Application of smart pdlc films
Smart pdlc films appear in flexible structure and in rolls. Moreover, manufacturers make it by cutting according to the dimensions of the glass to be applied. Hence, in the production of PDLC class smart glasses, we follow two different ways:
- bonding self-adhesive PDLC films to glass and
- Laminating PDLC films between glasses.
We can use self-adhesive PDLC films by adhering to all flat and curved glass, organic glass and other transparent surfaces. Subsequently, it is suitable for interior and exterior glass for architectural applications. In these applications, if there is an existing glass system, we can apply it without changing, by sticking on it.
Exterior Applications of Smart Glasses
Manufacturers use double-glass systems for thermal insulation on the exterior. In these systems, there is a gap between the two glasses on the interior and exterior walls. And this space comes with dry air or argon. Conditions such as the usage purpose, climate and expected benefit of façade glasses determine the structure of double-glazing systems.
According to the needs of safety, UV protection, it is necessary to use laminated glass on the outside or inside. And that these smart pdlc should be low-e or solar low-e coated.
How long does international shipping take?
The shipment is made in a week, once the payment is credited. The arrival time will depend on the destination and the chosen transport. Shipments by air courier services do not take more than a week.
What is the operational voltage of smart pdlc?
The system operates at a voltage between 48 and 60 VAC. The transformer provided by Smart Glass must be used. Moreover, it should never be connected directly to the electrical network.
Can multiple glass panels be connected together?
Yes, in that case the connections must be made in parallel.
Is your energy consumption efficient?
Yes, the electricity consumption is less than 5W / m2. On the other hand, the filtering properties and the practicality of the system result in energy savings in air conditioning and lighting.
Does it filter UV rays?
Yes, in transparent mode it blocks 90% of UV rays and 30% of IR rays. Similarly, in opaque mode it blocks 99% of UV and 90% of IR.
Do they serve to completely darken an environment?
No. The main function of SMART GLASSES is instant privacy. In opaque mode they provide total privacy , but allow light to pass through in a diffuse way. By using darker sheets or tinting the glass, you could achieve greater darkness in windows that do not receive direct sunlight, but the transparency would also be reduced.
Can the shape be customized?
We can cut smart pdlc cut into custom shapes and sizes, provided electrical continuity is respected.
What is the percentage of transmission of smart glasses in transparent mode?
Transmission in the “on” state is approximately 78% when viewed directly (perpendicular). Transparency decreases when the viewing angle is more oblique.
Where are the busbars and cables used to feed the film located?
The bars are generally located on the short sides of the film, although the final configuration will depend on the size and shape of the glass.
What is the shelf life of the film?
The life of the smart pdlc is more than 10 years.
What is the operating temperature of smart pdlc?
-Thirty degrees centigrade to +60 degrees centigrade.
Smart pdlc films are becoming popular day by day. Since every business is expanding, you need to install latest decoration objects. These privacy films bring security, beauty, and satisfaction of operation.
