Several methods for effectively discriminating film quality
[China Glass Network] I think there are so many people who are eager to find small and cheap. Here I want to remind the majority of car owners, don’t want to buy a small cheap and lose huge benefits, so that you not only lose watermelon, but also sesame you later. Also not available, here I would like to recommend several ways to effectively distinguish the quality of the film. Please remember:
First, touch the hand. The high-quality film feels thick and smooth, and the inferior film is very soft and thin, lacks sufficient toughness, and is easy to wrinkle.
Second, the nose smells. The residual solvent in the inferior film adhesive layer has high benzene content and odor, which will seriously endanger the health of the owner.
Third, the eyes. Seeing perspective, clarity, high-quality explosion-proof film can be as high as 90% or more, and regardless of the color depth, the see-through performance is good, and can maintain a good line of sight at night and rain. The inferior film adopts the ordinary dyeing process, and is insulated by color, so the color is deep, and there is always a misty feeling from the inside of the car.
Fourth, the teeth bite. Use a tooth to bite the film lightly. If there is a clear spot on the bite, it means that the film is viscose colored instead of using bulk infiltration and sputter metal coloring. This is not the case with bulk infiltration.
Fifth, look at quality assurance. Only the film with the manufacturer's warranty card is trustworthy. The manufacturer's warranty card usually includes the warranty item, the age, the payment method, and the real name and phone number of the manufacturer.
6. Look at the back of the film for anti-counterfeiting marks. The anti-counterfeiting mark is printed on the back of the explosion-proof film of the regular brand.
7. Rub with alcohol and gasoline. Because the inferior film is a gel dyed film, after removing the protective layer of the film and wiping the adhesive layer, the fading phenomenon can be seen. It is also possible to uncover the transparent layer on the back of the film, and use a hard object to scratch it, and the inferior film is more serious.
8. Refer to the technical parameters provided by the manufacturer: transparency, shininess, and heat insulation. Generally, the more transparent the film, the lower the heat insulation; the more reflective the film, the higher the heat insulation. A film with high transparency, low reflectivity and good heat insulation is a fine film.
Nine, test the insulation effect. The ability of the film to block heat is tested using a powerful solar light source such as a high-power incandescent lamp. The high-quality explosion-proof membrane insulation rate should reach 80%, the inferior film insulation rate is low, and it will be very stuffy when sitting in the car. At the same time, it has a very poor UV-blocking effect, and it can not protect the car items and passengers. The role.
X. Anti-scratch is a basic performance of automotive film. When the high-quality film lifts the window normally, the surface of the film will not be scratched, and the inferior automobile film has obvious defects in this respect.
