How to Repair a Damaged Car Window Film?
1 Answers
Generally, it is not easy to repair damaged car window film, and it is recommended to directly replace it with a new one. Below is more information about car window films: 1. Introduction: Car window film (Autofilm) refers to a thin layer applied to the front and rear windshields, side windows, and sunroof of a vehicle. This thin layer is also known as solar film or heat-insulating film. 2. Functions: Its primary functions include blocking ultraviolet (UV) rays, reducing heat transmission, preventing injuries from shattered glass, reducing glare, and protecting personal privacy through its one-way visibility feature. Additionally, it helps minimize damage to interior items and passengers caused by UV exposure. By reflecting sunlight physically, it lowers the interior temperature, reduces the use of air conditioning, thereby decreasing fuel consumption and saving costs. 3. Working Principle: The film is made by depositing multiple layers of highly insulating metal coatings, such as aluminum, gold, copper, and silver, through vacuum evaporation or magnetron sputtering technology. The outer shell electrons (free electrons) in the metal materials are generally not bound by the atomic nucleus. When exposed to light waves, the electric field of the light causes the free electrons to absorb the light's energy, generating oscillations at the same frequency as the light. These oscillations then emit light at the original frequency, known as light reflection.
