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

+ 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	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
