There are more and more questions about automobile film foaming on the Internet. Some bubbles appear within a few days after the film is applied, and some bubbles appear several years after the film is applied. What's the matter, what is the reason for the blistering of the automobile film, and how to solve it?
1、 Blistering phenomenon of automobile film
There are usually two kinds of bubbles. One is that the white spots like bubbles and blisters appear soon after the car is coated; In another case, the automobile film has been applied for several years, and large and small bubbles begin to appear on the film, especially at the rear windshield.
2、 The reasons and treatment methods of automobile film foaming are different for the above two foaming phenomena.
(1) If this is the case, the main reason for blistering soon after the film is pasted is that most of the film is wet. When the water between the film and the glass is not exhausted, it will volatilize the next day or after a period of time and gather into small blisters or water mist bubbles, which are generally small and not many, like pockmarks, and will not affect normal driving. Generally, this kind of situation is common in automobile film coating construction, which is a normal situation.
② The main treatment methods are as follows: the treatment method is also simple. Under normal conditions, wait for a few weeks. If it is long, the water will disappear after volatilization (Note: the heat insulation effect of automobile film is more and more, and the longer the time is).
(2) If it is another case, bubbles are found after a few years of automobile coating. 80% of this kind of bubbles are pure bubbles, which will become more and more large with the extension of time.
① The main reason is: the main reason is that the volatilization of toxic gas is generally the performance of inferior membrane. There are benzene, aldehyde and other elements in the adhesive layer (or glue) of this film. After a period of ultraviolet irradiation and heat acceleration (such as the heating wire of the rear window), formaldehyde and other toxic gases will volatilize and form bubbles. Usually, it is accompanied by the obvious smell of the car.
② Treatment method:
Treatment methods: there are various retention methods on the Internet, such as taking a needle to break bubbles, releasing gas, and then scraping with a scraper: however, it is not advocated. This effect can not remove roots, and the released gas is toxic, which is the performance of inferior film: a good treatment method is to tear off and paste again!
