First, how to choose the car film
Ask the index. The so-called explosion-proof membrane must have the functions of heat insulation, explosion protection and ultraviolet protection. Therefore, consumers can consult the sales staff in detail when choosing, so as to judge whether the quality is true or false.
Look at the color. Usually, riot movies use light green, sky blue, gray, brown and natural colors that are more comfortable for eyes. The explosion-proof film is uniform and soft in color, and there is no uneven chromatic aberration of waves, so the scenery naturally does not change color when viewed from the car. Ordinary color film directly melts the color into the film, and after tearing off the upper plastic paper, the color of the scraping surface will fall off. In addition, the common color film will fade when it is gently wiped on the ground.
Three smells. In the residual solvent in the adhesive layer of inferior film, the benzene content is high, which will have an odor, while the good film is professionally treated before leaving the factory, and the odor is small. Experts warn that long-term smell of this smell will seriously affect the health of the owner.
Four touches. Generally, the thickness of safety explosion-proof membrane is not less than 1.5mil, so it feels thick and smooth. In addition, because its surface is hardened, it generally does not scratch the surface. However, ordinary color film is thin and brittle because of its insufficient thickness, which will leave traces on the film in the process of shaking the glass.
The selection of automobile film mainly involves the following parameters:
Explosion-proof performance: This is another important performance related to safety. High-quality explosion-proof membrane itself has strong toughness. The broken glass can be stuck by the film, which will not splash and hurt people, and has strong impact resistance. Inferior explosion-proof membranes are soft to the touch, lack sufficient toughness, are not resistant to ultraviolet radiation, and are easy to age and become brittle.
Light transmittance: This is the most important performance of automobile film related to driving safety. Users are advised not to choose films with too low transmittance, especially those on both sides of the front window. The substrate used in the front car film is clear enough, even if the film color is dark, the scenery you see should be clear and not dim and deformed. More than 85% transmittance is suitable. At this time, the side window film does not need to be dug, which does not affect the line of sight. When driving at night, it can also reduce the strong glare reflection of the oncoming car headlights on the rearview mirror, making the eyes very comfortable. In addition, good sight can be ensured when driving, reversing and turning around on rainy nights.
Thermal insulation rate: The high-quality automobile explosion-proof membrane can reflect infrared rays, so the temperature inside the car is much lower, which will reduce the air conditioning load and save fuel. If the car is the main judge, the method is simple, just block the sun with coated glass and feel its heat insulation effect with your face or hands.
Ultraviolet blocking rate: for high-quality films, this index is generally not less than 98%, and the high one can reach 100%. The ultraviolet blocking rate is high, which can effectively prevent people in the car from being burned by excessive ultraviolet radiation, and can also protect the car stereo from sunburn. Many inferior membranes do not have this index, or are far below the standard of 98%. This is also the main basis of the product warranty period.
Second, the benefits of car film
1, safe and explosion-proof. The base layer of the film is polyester film, which has the function of resisting tearing and breakdown, and prevents the glass from accidentally breaking and causing secondary injury to drivers and passengers.
2, heat insulation and sun protection. The film can solve a lot of heat generated by infrared rays, and the temperature of the car body is greatly reduced, as is the temperature inside the car.
3. Reduce the energy consumption of air conditioners. The loss of refrigeration capacity of heat insulation film air conditioner can be compensated, which can prevent the temperature inside the car from being too high to a certain extent, and achieve the effect of saving oil consumption and reducing energy consumption of air conditioner to a certain extent.
4, anti-UV. The medium wave and long wave in ultraviolet rays can penetrate very thick glass, and 99% of ultraviolet rays can be blocked by sticking a layer of heat insulation film. Prevent skin damage and reduce the aging of automobile interior. For example, 3M's Jing Rui 70 front screen can block 99.9% of ultraviolet rays, which is 56 times that of SPF40.
5. Anti-glare. Keep your eyes comfortable. Reduce accidents caused by glare factors.
6. Create a private space. You can't see the inside of the car clearly after sticking the film, but it doesn't affect the scenery inside the car. In this way, privacy and security can be effectively protected.
7. Improve aesthetics. According to personal preferences, you can personalize and beautify the car by sticking a film.
