First, the cause of car film foaming
There are two main reasons for bubbles in automobile film: one is the quality problem of automobile film itself, and the other is the construction quality problem when those films are attached to automobiles.
The first reason is that the majority of car owners should effectively determine whether the selected film is a brand car film and whether the selected car film is genuine before sticking the car film. If the car film quality is not up to standard and there is no warranty card to guarantee it, then foaming, degumming and fading are inevitable.
Therefore, it is suggested that the majority of car owners should not be greedy for cheap when choosing car films. If they want to choose, they should choose brand car film. Only in this way can the quality of car film be effectively guaranteed, thus reducing the possibility of failure after car film.
Second, the car film foaming solution
If the quality problem of car film has been ruled out, then it is the second case. After all, car film pasting is mainly manual operation, and some mistakes will inevitably occur during the film pasting process. What should I do if there are bubbles in the car film? Regular car film shops generally use the following methods to eliminate bubbles:
1, gently cut a small mouth obliquely from the bubble side of the film with an art knife, and then scrape it effectively with a scraper and a baking gun.
2. Gently tear the foaming car film in half, and then stick it slowly according to the normal film pasting process.
3. If the foaming is mainly caused by air entering the membrane, the influence is not great, because the air entering does not have much influence on the adhesion of the membrane, just find a sharp object such as an embroidery needle to puncture it, and then blow dry the bubbles with a flat plate.
If it is caused by dust, sand and other impurities, it will be more troublesome. You need to take the warranty card to the professional film pasting place to find a professional to handle it.

Car film classification:
There are three kinds of automobile thermal insulation films: dyed film, metal film and magnetron sputtering film. . In order to make it easier to understand, we can divide the types of car film into six categories.
First, dye the film. Refers to the lowest automotive film, which is thin, non-insulating and easy to fade. Generally, there are many small shops, which are very cheap. It only costs one or two hundred yuan to paste the whole car. "Tooth waist is pale" is its most remarkable feature. This kind of membrane is generally produced in Taiwan Province Province, China.
Step 2, coating the printed film. This is a unique craft in Korea. Generally thicker. This kind of film has good heat insulation, but its perspective is slightly poor.
Third, ordinary metal film. It is made by spraying metal on the colorless original film layer. Commonly used metals are aluminum, iron, etc. This kind of membrane is generally produced in China, Indian, Japanese and American. This metal film is the most common one on the market. The composition of the film (generally, metal is evaporated by heating on the film-based material), but this film has general perspective and thermal insulation, but the price is not low.
General beauty shops often use this kind of film to pretend to be the top film. Many well-known brands are actually this kind of ordinary metal film. Because it entered the market earlier, consumers mistakenly thought that this film was a high-grade film.
Fourthly, nano-ceramic membrane. Based on nano titanium nitride, it is made by combining magnetron sputtering technology and metal nitriding technology, which is durable, not easy to corrode and does not interfere with electromagnetic signals.
The production area is not limited, and the United States, Japan and China all have this capacity. Amber optical nano-ceramic thermal insulation film is the latest ceramic film (in February, 2006, the global patent for multilayer nano-ceramic thermal insulation film was successfully applied for +0: 6,188,512).
5. Precious metal film. As the name implies, this kind of film also sputters metal on the colorless original film layer, but the difference is that all the precious metals such as chromium, titanium and platinum are sputtered. In addition, the sputtering method of this film is "magnetron sputtering". This is a complicated process. This film is characterized by natural color, good light transmittance and good heat insulation.
Six, magnetron sputtering coating. Multilayer polyester film technology. This is another technical trend of high-end movies. By multi-layer extrusion technology, 240 layers of polyester films are stacked together to make a thermal insulation film with a thickness of only 0.05mm, which has the characteristics of high visible light transmittance, good thermal insulation, long service life and no electromagnetic signal interference.
