In the growing automobile market, car owners' demand for automobile window film is not only to improve the appearance of the vehicle, but more importantly, to insulate, protect against ultraviolet rays, increase privacy and protect the driver's sight. Automotive window film is an important part of the vehicle. Correctly judging its service life and replacing it in time are crucial to ensuring the safety and comfort of driving.
Identify the timing of replacement
The service life of automobile window film is affected by many factors, including material, quality, installation method and daily maintenance. Car owners can tell whether their window film needs to be replaced by the following signs:
1. Color fading or discoloration: After long-term exposure to sunlight, window film may fade or discolor, affecting the appearance and visual effects.
2. The appearance of bubbles and wrinkles: A high-quality window film should be smooth and streak-free. If you find a lot of bubbles or wrinkles, the film may be old or poorly installed.
3. Peeling or peeling at the edges: Peeling or peeling at the edges of the window film is a clear sign of replacement and indicates a decrease in adhesion.
4. Blurred vision: If the window film becomes opaque or blurry, it will directly affect driving safety.
5. The heat insulation effect is reduced: If you feel that the temperature inside the car is higher than before, it may be that the heat insulation performance of the window film has been reduced.
The lifespan of different car window films
1. The tinted film can only be used for one year.
Because the tinted film directly applies the pigment to the surface of the base material or glue, it cannot be used for too long. Many such films are of poor quality and have basically no heat insulation, sun protection, and explosion-proof capabilities. If they are used for too long, they may even affect driving. safety.
2. The single-layer structure metal reflective film can be used for two to three years.
The main raw materials of single-layer metal reflective film are ordinary metals such as aluminum and nickel, and the manufacturing process is evaporation. When casting the film, the manufacturer will melt the metal at high temperature, so that the metal atoms will evenly adhere to the substrate film along with the steam to form a metal layer, thereby playing a reflective and heat-insulating role.
The metal atoms evaporated by this process simply float on the substrate through the steam, like chocolate powder sprinkled on the substrate after making a cake. Although it can ensure uniformity, the adhesion is average, and obvious fading will occur after 2-3 years of normal use.
3. The magnetron sputtering process film can be used for 5 to 10 years
The most advanced solar films currently on the market are produced using magnetron sputtering technology, such as multi-layer composite metal films and ceramic films. Magnetron sputtering refers to a low-pressure inert gas environment that causes high-speed electric shock to various metals or ceramics, causing the target material to be sputtered onto the substrate.
Compared with evaporation technology, the metal atomic structure adsorbed on the substrate by magnetron sputtering technology is evenly distributed, and the effect is clearer and more translucent.
And because the energy efficiency carried by metal atoms is higher (usually 100 times that of evaporation technology), the material has better adhesion and is less likely to fade and age. The life of the magnetron sputtering film is at least five years, and if maintained and used properly, it can even be used for ten years.
Suggestions from experts in various industries
1.Traffic safety experts emphasize that timely replacement of car window film is one of the important measures to ensure driving safety. It not only protects drivers and passengers from UV rays, but also reduces the risk of injury from glass fragments in the event of a car accident to a certain extent. In addition, high-quality window film can effectively reduce the temperature inside the car and improve driving comfort.
2.Car repair and maintenance experts recommend that car owners should choose a reputable and professional installation service provider to replace the window film to ensure the performance and installation quality of the window film. Regularly checking the status of the window film and replacing it according to actual conditions can maximize the service life of the window film and ensure driving safety and comfort.
3.Today, as the automotive supplies industry continues to develop, choosing the right time to replace window film is not only related to personal driving experience, but also the responsibility of every car owner. Please pay attention to the condition of your car window film in time to protect the safety of yourself and your family.
