Automotive glass film is a film-like object on the front and rear windshield, side window glass and skylight of the vehicle to block ultraviolet rays, block part of heat and prevent the person from injuring and anti-glare caused by sudden burst of glass. It can protect personal privacy. In addition, it can also reduce damage caused by ultraviolet radiation caused by items in the car, reduce the temperature inside the car through physical reflection, reduce the use of car air conditioners, thereby reducing fuel consumption and saving some expenses.
What should attention to when buying a car film?
1. Transistance and clarity of the film
This is the most important performance of the car film for driving safety. It is recommended that users do not choose films with too low transparency. The window film, especially the film on both sides of the front row, should have a transmittance of more than 85%. More suitable. At this time, the side window film does not need to be boring and does not affect the line of sight. At night, when driving, the strong glare reflection of the rear headlights on the mirror can be weakened, so that the eyes are very comfortable. In addition, the line of sight can be guaranteed to be good when driving, reversing or turning around in the rainy night.
2,The thermal insulation properties of the film
A good quality car explosion-proof film can reflect infrared rays, so the temperature inside the car is much lower, which in turn reduces the air conditioning load and saves fuel. If the car is mainly judged, the method is very simple. Just use the film-coated glass to block the sun, and use your face or hand to feel the heat insulation effect.
3, Explosion-proof performance
The high-quality explosion-proof membrane itself has strong toughness. After the glass is broken, it can be adhered to the film without splashing and injuring people, and its impact resistance is very strong. The inferior quality explosion-proof membrane feels soft, lacks sufficient toughness, is not resistant to ultraviolet radiation, and is easy to age and become brittle.
4, UV blocking rate
For high quality membranes, this indicator is generally not less than 98% and high up to 100%. The high UV blocking rate can effectively prevent people in the car from being exposed to excessive ultraviolet rays, burn the skin, and protect the car's audio from being sunburned. Many inferior membranes do not have this indicator, or far below the 98% standard.
5, View the license card and warranty card
If you choose a business film, you must see if there is an authorized card and a warranty card for the brand. If there is a license, the quality is relatively more secure. If not, the source is unknown. Most brand warranty cards are numbered, and there are manufacturers phone and test locations, which are convenient for inquiries. If there is no number or business information, it may be a "cottage warranty card".
6,Look at the packaging
Before the film is applied, it is best to look at whether the volume on the package and the film axis are the same, and whether the label has been altered. If it is modified, it may be recycled genuine packaging to make a fake. Generally, the well-known brand automobile film has the original factory label on the packaging. The inner wall of the film shaft has the film roll label and the film roll number. When the manufacturer tests, the circulation link of the film can be detected through the film roll number. Most of the regular channels come from the film, and there will be a LOGO printed on the box.
7,Touch by hand
Before the film can be touched by hand, the high-quality glass film feels thick and smooth, and the inferior film feels very thin and soft, lacks sufficient toughness, and it is easy to wrinkle when it is slightly folded.
8, With the nose smell
The inferior film has the low quality and low cost of the glue. Therefore, when the inner liner of the film is torn open, a pungent gas will be emitted immediately, and accompanied by a smelly smell, affecting the health of the passenger. The true film does not have any pungent odor after it is torn. It uses environmentally-friendly glue and does not affect passenger health.
9, Test the anti-scratch effect
When selecting the film, the owner can use the nail to scrape back and forth on the glass film. If it is easy to scratch, it may be a fake film. Because the good quality film will have a scratch-resistant coating, the surface of the film will not be scratched so easily, so the life and warranty period of the original film will be longer.
10,The price
The purchase price of genuine film and inferior film is very different. Generally, the price of the regular chain decoration store or 4S shop film is almost above 2000, and some auto parts city merchants offer less than 1,000 yuan. At this time, you need to be careful, don't try to use the fake film.
11, Look at the color
The true film has good clarity and transparency regardless of the color depth. The inferior film will have optical distortion, and some will have a misty feeling, not enough. The fake film will show severe fading after 1 to 2 years of use. You can see the window glass down a little, but the true film does not.
12, Shelf life
Generally, the membranes produced by regular manufacturers have a long quality guarantee period, usually 5 years.
