1. Intelligent Liquid crystal dimming film
1.1. Introduction to liquid crystal dimming film Intelligent Liquid crystal Dimming film is also known as PDLC Liquid crystal film (polymer dispersed Liquid crystal), PDLC Chinese called polymer dispersed liquid crystal, also known as electrically controlled dimming film, electrochromic film, electronic curtains and so on. It is a kind of application technology product based on membrane layer.
The rod-shaped polymer liquid crystal is mixed with the prepolymer, attached to the transparent conductive substrate, so that it has liquid and crystal characteristics at the same time, the polymer in the absence of electric power presents a disorderly arrangement state, the film layer presents a atomization state, and the polymer in the electrified state is arranged in an orderly manner according
1.2. Liquid crystal dimming film characteristics 1.2.1. Privacy protection
The biggest function of intelligent dimming film is to have the function of privacy protection, which can control the transparent and opaque state of glass at any time;
1.2.2. Projection function
Because of the non-transmittance of the intelligent liquid crystal dimming film in the state of power outage, and its milky white and light gray dimming film in the state of power outage has a very good projection effect, when and both sides can be viewed;
1.2.3. Energy saving and environmental protection
Power-on state per square consumption of only 4~5W, low electricity consumption, with high barrier infrared and ultraviolet effect, in the application process has a very good energy-saving and environmental protection performance, presumably other energy-saving and environmental protection products have more advantages
1.2.4. Sound insulation and safety ,The membrane layer has the sound damping, effectively blocks most of the noise, the film layer protection glass in the damage process can avoid the glass splash, the fight strength is good.
2. Intelligent liquid crystal dimming film category
2.1. Self-adhesive liquid crystal dimming film: The fully self-adhesive liquid crystal dimming film is a composite silica gel layer and hardened layer combined on the basis of PDLC-flim dispersed polymer liquid crystal dimming film. In addition to maintaining the original dimming film “Transparent, power-off atomization” and other characteristics, but also has “dry straight paste, dynamic exhaust” and other characteristics.
Compared with the traditional clamp dimming glass, the self-adhesive film has the advantages of “light weight, convenient transportation, convenient installation” and so on, which is the best optional scheme to realize the rapid switching of glass partitions and hide space, and can be used as the background wall and projection curtain wall and other places.
2.2. Adhesive type Liquid crystal dimming film: The clamp type dimming film is the main form in the process of using the dimming film at present, and it is the most common dimming film on the market. Its structure is the simplest, is the intelligent dimming film and PVB of the latter EVA through the clamping process production customization, clamping type dimming film in such an application process performance is more stable. That is, the application of dimming glass, details can be seen (dimming glass-technical standard). Compared with the performance of the dimming film, the transmittance of the dimming glass is higher than that of the self-adhesive dimming film, and the safety type is higher, and the service life is longer.
5. Maintenance and use recommendations
5.1. Recommendations for use Through the above intelligent LCD Dimming film Operation guide the correct installation of self-adhesive dimming film, to ensure that the film layer and glass surface complete full fit, to avoid the production of bubbles and impurities, such as the existence of film and glass, long-term easy to lead to a decline in the service life of the film, and even affect the normal work of the film layer,
Avoid applications in wet and warmer places during use: Recommended application sites (indoor partitions, windows, other projection curtain wall and other places, low space humidity, small temperature difference of the application site) self-adhesive membrane electrode protection, the use of neutral glue reasonable installation of self-adhesive film.
5.2. Maintenance & amp; cleaning In the maintenance process to avoid the use of glass cleaner cut rub on the surface of the film, self-adhesive cleaning method as far as possible with softer towels or dry cloth to clean the surface dust and other impurities. Let the surface of the film may be kept clean, or wipe the surface of the dimming film with alcohol/a small amount of water, and then wipe the surface of the dimming film to a dry state with a cotton cloth such as a spectacle cloth.
7. Packaging and storage of liquid crystal dimming film Packaging: The Use of box/reel and other packaging methods, transport convenience, sheet generally used in wooden box packaging, each piece between the use of paper or foam sponge separated, effectively protect the integrity of each dimming film, reel can greatly reduce packaging space, effective transport and acceptance, according to the requirements, will be equipped with electrodes and control systems.
Storage: Liquid crystal dimming film if not used for a long time, should be placed in ventilation, drying, air humidity -15℃~50℃, relative humidity 85%RH below the environment, the principle of sunlight exposure and contact with acid and alkaline gases and liquids, not wet and soaked.
