Reflective window film
Film reflective insulation (Reflective Window Films) is relying on intelligent reflection to reach the purpose of spectrally selective window film, it appeared to solve the heat window film film----quadratic radiative heat transfer problem of congenital defects. By magnetron sputtering technology will be gold, silver, titanium, nickel, precious metals such as Indium sputtering evenly to PET substrate multilayer optical level to close high-heat metal film, in the solar spectrum to lasting infrared heat reflective thermal insulation. Been widely used in automotive, architectural glass and other industries.
Most reflective window film by magnetron sputtering or multilayer sputtering processes together. Gold, silver, titanium, nickel, precious metals such as Indium sputtering evenly to PET substrate multilayer optical level to close high-heat metal film.
Multilayer by magnetron sputtering process has become the coating composite technology and deep dyeing, vacuum thermal evaporation technology, magnetron sputtering process after yet another technical highlights.
Heat absorbing film temperature will rise after the heat and far infrared to the car or indoors in the form of heat radiation, causing the second radiation. Make people feel hotter.
Reflective film using metal heat shields most of the infrared heat reflecting off, to prevent secondary radiation, a lasting heat insulation effect.
According to the GB/T2680 architectural glass optical window glass measuring method for performance of rules, total solar energy transmittance for solar direct transmittance and pass and to the Interior side of the secondary. most of the heat insulation performance of film in a time does not take into account secondary radiation.
