Precautions for car film pasting
First, after the car is pasted, the glass will not be lifted or lowered for one week. Generally speaking, it takes 5-7 days for the car film to be fixed on the window. In the meantime, try not to lift the glass to avoid the displacement of the car film that is not fully bonded.
Second, after the car film, don't wipe it for a week. The newly attached car film is prone to fogging, which is a normal phenomenon in the drying process of solar film. Generally, it is normal for about a week to half a month. Just wait until it disappears slowly. Never wipe it.
Three, after the car film, don't use sharp, hard tools to scratch. Because if the owner does not pay attention, the transparency of the car film will be greatly reduced after scraping it with a sharp and hard weapon. Therefore, try to wipe the film surface with a soft cloth such as a wet towel when washing the car, and avoid using corrosive chemical solvents to wipe the film surface of the car.
In fact, there are not only the above three points to pay attention to, but also many things, such as trying not to hang puppets, dolls and other small ornaments on the window. Hanging ornaments may or may not pull the film out of the gap when pulling up the sucker and sticker. If this happens or the car film is loose, I suggest you go back to the film shop and let professionals repair it again to ensure the effect and durability of the car film.
Automobile movie introduction
Grade film pasting
Whether to shoot a new car is controversial in the industry. Some people think that cars under 200,000 need to be coated with heat insulation film, while luxury cars over 200,000 need not be coated, because there is green heat insulation glass, and luxury cars over 400,000 are double-layer heat insulation glass (with heat insulation layer in the middle).
Thermal insulation film has four functions: heat insulation, light insulation, explosion protection and energy saving. The process of thermal insulation film has gone through four stages: dyeing film, metal coating, magnetron sputtering film and multilayer optical film. At present, the most advanced magnetron sputtering film adopts aviation technology-vacuum magnetron sputtering technology, which can block 30%-80% of sunlight heat by reflecting visible light, ultraviolet light and infrared light. The multilayer optical film has excellent spectral selectivity, can obtain high thermal insulation under the condition of ensuring high light transmittance, and is more environment-friendly and energy-saving. Whether it is Porsche or Chery QQ, the owner can choose the film.
The new car film not only helps to insulate heat, but also reduces the strong sunlight during the day and plays an anti-glare role at night. Especially the window film and the front windshield can avoid the sun exposure in summer and prevent the skin from being tanned. In addition, due to the adhesion function of the thermal insulation film, if the automobile glass is broken, it will stick together, reducing the harm to the human body, which is the anti-burst function.
quality assurance
Automobile film pasting is a relatively technical process, and the effect of film pasting is related to the skills and tools of technicians. Film pasting should be constructed in a dust-free workshop, and the regular film pasting tools cost more than RMB 1000.
Film pasting process is more important. The whole car film includes front windshield, side window and rear windshield, which usually takes 3-4 hours, so usually a technician can only paste 2-3 cars a day.
It is understood that many manufacturers and 4S stores have publicly indicated that they are not suitable for fitting models with large curvature of rear windshield, such as Beetle, Citroen C5, POLO and Tianyu hatchback. However, professional technicians trained in strict international standards can complete the film pasting of this car with sophisticated tools.
Reminder 1: Avoid using the blade when cutting the film. Sometimes car owners complain that the front and rear windshields are scratched. One reason is the use of ordinary razor blades, and the other reason is that the angle is too straight. It is suggested that construction technicians use NT red dot art knife to cut the film, which is both soft and sharp. 30-degree oblique cutting can effectively avoid scratching the glass.
Reminder 2: spread a big towel on the car. In the regular film pasting site, a large towel should be laid on the car to protect the front hood, seat and trunk lid.
Reminder 3: Don't lift the glass for at least three days. The thermal insulation film is divided into two sides, and the side with glue will stick to the glass when it meets water, so you can't lift the window glass for at least three days after sticking the film.
kickback
There are hidden dangers in inferior thermal insulation film, which is not only not conducive to the physical and mental health of car owners, but also has potential safety hazards.
"Pancake"-Glass absorbs heat
Case: The window of Miss Wang's house has become very hot since the solar film was attached, and pancakes can be baked.
Analysis: Miss Wang may have touched the total absorption film. Ordinary thermal insulation films are usually both reflective and absorptive. In addition, the absorption efficiency of absorbent is easy to decay, and the thermal insulation effect will be weakened after 1 year.
"Myopia"-low definition
Case: Although the film pasting master carefully left two small holes in the rearview mirror when pasting film on Mr. Cao's car, he always felt "nearsighted" when sitting in the car, and his vision was particularly blurred.
Analysis: The poor definition of the film is mainly related to the manufacturing process of the film and the glue used. The clarity of dyed film on the market is very low, and the clarity of metal sputtering film is better.
"Smell bomb"-emitting peculiar smell
Case: Mr. Wu's car always smells bad after being exposed to the sun.
Analysis: This may be related to the poor quality of glue used for thermal insulation film. In addition, the poor quality of glue will also lead to insufficient adhesion and poor explosion resistance.
"dazzling sword"-serious light pollution
Case: Last summer, Mr. Yu had a car accident. At a sharp turn, he was dazzled by the strong light reflected from the glass of the opposite car, causing him to drive into a small ditch next to him.
Analysis: Normal films require very low reflectivity for visible light, while some inferior films have very high reflectivity, which leads to a large number of dazzling "lightsabers" appearing in the streets, causing light pollution.
