Selection of automobile film:
First, dye the film. Refers to the lowest automotive film, which is thin, non-insulating and easy to fade. Generally, there are many small shops, which are very cheap. It only costs one or two hundred yuan to paste the whole car. "Tooth waist is pale" is its most remarkable feature. This kind of membrane is generally produced in Taiwan Province Province, China.
Step 2, coating the printed film. This is a unique craft in Korea. Generally thicker. This kind of film has good heat insulation, but its perspective is slightly poor.
Third, ordinary metal film. It is made by spraying metal on the colorless original film layer. Commonly used metals are aluminum, iron, etc. This kind of membrane is generally produced in India, Japan and the United States. This metal film is the most common one on the market. However, this kind of membrane is generally transparent and heat-insulating, but the price is not low. General beauty shops often use this kind of film to pretend to be the top film. Many well-known brands are actually this kind of ordinary metal film. Because it entered the market earlier, consumers mistakenly thought that this film was a high-grade film.
Fourthly, nano-ceramic membrane. The high-grade membrane is made by spraying "silicon" particles on the colorless original membrane layer by nanotechnology. This film is a new technical product, which has good heat insulation and transparency, and has the characteristics of not interfering with electronic signals and environmental protection. Generally produced in Japan.
5. Precious metal film. As the name implies, this kind of film also sputters metal on the colorless original film layer, but the difference is that all the precious metals such as chromium, titanium and platinum are sputtered. In addition, the sputtering method of this film is "magnetron sputtering". This is a complicated process, as long as the United States has this technology. The film is characterized by pure color. The "Youbo" sold by Li Chexing and the "Gu Wei" on the market are such films.
Six, double noble metal film. Only the CPFILM factory in the United States has this top-level explosion-proof heat insulation film. This film adopts the latest magnetron sputtering technology, and precious metals such as titanium and platinum are sprayed on both sides of the colorless original film. This film has a double layer of metal. Therefore, the reflection is low, the constant temperature in the car is maintained, and the fuel consumption is reduced. And the color is crystal clear and transparent, with the characteristics of one-way light transmission. Crystal clear from the inside out, looming from the outside. The brand "Weibang" of Dingli Glass Functional Film Company is this kind of film, which can also effectively block 99% of ultraviolet rays and protect your skin.
Seven, identify the quality of the film, feel delicate and not rough, feel the better the insulation effect, the higher the insulation rate. Tearing off the northern mask and rubbing it on the ground is an ordinary film, but on the contrary it is an explosion-proof film.
Eight, touch hands; Inferior car films are often very thin, soft to the touch, lacking sufficient toughness and easy to wrinkle, while high-quality car films are thick, smooth and textured to the touch.
Nine, the nose smells; Take out a small piece of car film, tear off the protective film inside and ask with your nose. Inferior car films will stink. The glue used for this car film is not good Never buy it.
X. See a good car film, with high visual angle and strong clarity. Although the color of the film is relatively dark, it will not be blurred when viewed indoors.
1 1. Use alcohol or gasoline; Because the inferior film is dyed with glue, remove the inner protective layer of the film and wipe off the glue layer, that is, see the fading phenomenon. You can also uncover the transparent layer on the back of the car film and scratch it with a hard object. The fading of inferior film is more serious.
12. Check the authorization certificate of the car film shop and the car film parameters provided by the car film manufacturer. Generally, the more transparent the film, the lower the heat insulation; The stronger the reflectivity of the film, the higher the heat insulation. The film with high light transmittance, low reflectivity and good heat insulation is a high-quality film. Just like the "Tianji Car Film" film itself has high light transmittance, low luminosity and good heat insulation, which is the certification result obtained by hundreds of thousands of riders.
Thirteen. Test the heat insulation effect. The thermal insulation rate of high-quality explosion-proof membrane should reach about 60%, and the thermal insulation rate of inferior membrane is low, which will make people feel bored sitting in the car. At the same time, the ultraviolet shielding effect is poor, which can not protect the articles and passengers in the car. Test method: High-power incandescent lamp is used to simulate the source of sunlight and test the thermal resistance of the film.
Fourteen, scratch prevention; Scratch resistance is a basic property of automobile film. When the high-quality film lifts the window normally, there will be no scratches on the surface of the film, but the inferior car film.
There are obvious defects in this respect. Test method: put the two films into water, and rub the front of the two films hard to the front several times by hand to see if there will be scratches on the surface of the car film.
Fifteen, the technology of film technicians; Professional film technicians shall accept the technical training of automobile solar film production enterprises and hold relevant certificates of professional automobile film technicians. When pasting the front and rear windshields, the film pasting master should use a whole piece of paving, and the solar film should be pasted on the automobile glass to the maximum extent.
