Characteristics of Switchable Film (PDLC FILM, Magic Film, Smart Film)

Characteristics of Switchable Film (PDLC FILM, Magic Film, Smart Film)

pincible of the privacy glass

+ The translucent state of switchable film

The switchable film is composed by two transparent conductive film laminating with a polymer liquid core. And the polymer liquid core composes crystal ball and polymer. When the light pass through the PDLC FILM and reach the liquid crystal ball and polymer, the light is scattering. And the switchable film appears translucent.

+ The transparent state of switchable film

When electricity power is connected, the polymer-liquid crystal core is allowing light pass through, the switchable film appear transparent.

+ Haze of switchable film

To identify the switchable film quality, haze (the opposite is transparence ) is the key parameter to describe the switchable film. When the power is on, the switchable film should be as transparent as possible , when the power is off, the switchable film should be more haze.

+ View range of the switchable film

If the scattering is more, the view range is wide, the switchable film appears more haze.

Unusual broken of EVA Vacuum Glass Laminating Machine

Unusual broken of EVA Vacuum Glass Laminating Machine

Unusual broken Reason solution

⑴Some part of film do not dissolve of the finished laminated glass

heating not average, circle wind is not big enough, blower wire connect wrong

①change the blower wire
②adjust the blower
③delay the high temperature keeping time

⑵there are air bladder on the surface of the finished laminated glass

①4 corner did not stick steady. ①stick 4 corners well
②Silica gel has hole ②amend the hole
③Vacuum pipe did not connect well ③check the vacuum pipe
④vacuum indicator do not reach the low point ④change the oil of the vacuum pump
Glass not flat enough Use other kind of glass

⑶There are air bladder on the edge of the glass

Lower temperature timing too short, open the silicone vacuum bag too early

Delay lowing temperature time, glass surface must reach 40℃-50℃ then stop the machine and take out
⑷Machine start switch get to stop from time to time Machine get wet or there is water in it Air-dry it
⑸cannot process as setting program ①the electricity wire loose ①connect the wire well
②temperature and timing indicator broken ②Adjust the temperature indicator and calculagraph
Heating the machine too slow Heating elements broken Adjust the current indicator, change the heating element
