Answer: different functions: the building membrane is mainly heat-insulating and ultraviolet-proof, and also has explosion-proof performance; Automobile film is mainly safe and riot-proof, and also has the properties of heat insulation and ultraviolet protection.
B: Different uses: As the name implies, building film refers to a kind of adhesive film specially used on building glass, and automobile film refers to a kind of special film specially used on automobile glass.
C. Different production processes: Usually, because buildings are fixed, films produced by vacuum aluminum plating often have high visible light reflectivity and high solar energy reflectivity, thus obtaining high solar energy control capability. Cars are not suitable for sticking highly reflective building films, because it will lead to strong reflection from the side window glass, which will affect the observation rearview mirror, and the glare on the glass will also affect the driver's driving. Therefore, in the general copying process of automobile film, vacuum aluminum plating and color film are used to eliminate the reflection, and the heat absorbed on the glass during the operation of the automobile is taken away by the fast flowing air, thus obtaining non-reflection and high heat insulation ability at the same time. With the continuous progress of technology and technology, the films produced by magnetron sputtering have the ideal of reducing visible light reflection and high thermal insulation.
D. The requirements for gold content of rare metals are different: the gold content of cadmium, nickel and titanium in car film should not exceed 5%, and the gold content of building film should not exceed 2.5%, which conforms to the overall requirements of environmental protection and ecology, because drivers are generally adults and healthy people, and people can't live in cars for a long time, while building houses include pregnant women, babies, the elderly and the sick. If the content of rare metals exceeds the standard, its radiation will affect the growth and intelligence of fetus and baby.
E. Both automobile film and building film can isolate ultraviolet rays: however, the structure of ultraviolet absorption layer is different. The ultraviolet absorption layer of automobile film is a high-pressure coating single layer, and the ultraviolet absorption layer of building film is a vacuum interlayer, which contains trace plutonium and can absorb harmful spectrum and adjust spectral frequency. Automobile film only works on UA in ultraviolet light, while building film works on UA and VB.
F. Different glues: Ordinary back adhesive (HPR) is used for automobile film, while building film is mostly transparent adhesive (CDF), while safety film is a special adhesive with stronger adhesion. Due to different properties, the service life of automobile film is about 3-5 years, while the normal service life of building film is 25 years.
G. Different color systems: The colors of automobile film are black, natural color, green, etc. The architectural membrane is rich in color and suitable for all kinds of buildings and cutting decoration.
H. safety: the safety and explosion-proof performance of the membrane is only related to its thickness. The thickness of automobile film is 1. 5MIL, and the thickness of the safety film is 4MIL- 15MIL, which is a real safety explosion-proof film.
1. Performance index: The performance index of building film is usually higher than that of automobile film, so besides its light transmittance and heat insulation rate, it is also necessary to know its reflectivity, U value, shading coefficient and other indicators.
J. Misuse of building film by car film: Ordinary car film is stuck on building glass. Due to the long-term exposure of the building, the back adhesive of the film will quickly deteriorate, and the film layer will fall off, fade and crack, which will seriously affect the beauty of the building.
