1, which is beneficial to adjust the temperature.
It is hot in summer, which can insulate heat and save cold air energy. The weather is cold and humid in winter, and the energy loss can be reduced and the temperature inside the car can be maintained after sticking the film.
Therefore, the thermal insulation performance of a membrane is also a matter of great concern to car owners.
2. Prevent harmful light from entering.
After sticking the film, it can effectively block ultraviolet rays harmful to human health and avoid sunburn, skin cancer or various diseases caused by excessive ultraviolet irradiation.
Step 3 reduce glare
After pasting the film, the glare caused by glass light can be reduced, and your driving will be protected.
4, to prevent glass splashing
After sticking the film, the safety base of sticking the film can prevent glass from splashing, avoid accidental injury and ensure safety.
5, automatically adjust the light
After sticking the film, the film can automatically adjust the light inside the car, which is suitable for any weather change and ensures a clear vision.
6. Protect the interior and the owner's skin from ultraviolet rays.
After pasting the film, the indoor decoration facilities will not be directly exposed to the sun, which will make the room as good as new for a long time, prolong the service life and improve the quality. For a woman who loves beauty, a car film with high ultraviolet barrier is essential, which can protect your skin from direct ultraviolet rays.
Step 7 save energy
After sticking the film, the heat insulation performance appears, and the air conditioning power does not need to be increased, which can greatly reduce the fuel consumption.
8. Private and beautiful
After sticking the film, privacy can be protected, and the dark film can reduce the perspective from the outside to the inside and prevent voyeurism. Choosing a film whose color matches the car paint can blend well with your car as a whole and add a lot of color to your car.
According to market analysis, there are more than 3,000 kinds of automobile films in China's market at present, and the names of automobile films are varied, and the quality and performance are also uneven. How to identify these brands and stick them on high-quality car films?
At present, I divide the types of automobile films on the market into five categories;
They are: imported brands, branded brands, branded brands, counterfeit brands and fake films.
Special attention should be paid to the following two kinds of membranes:
1. OEM film: It refers to registering a company and a brand in the United States or other European countries, and then purchasing car film from Korea, Indonesia, Guangzhou, Taiwan Province Province and other places, repackaging and OEM in China. Then write "American movies". such
"American movies" are legally recognized, but American trademarks do not represent American manufacturing. There are many brands of this kind of membrane, so I won't list them one by one. More than 90% of the market is made of this kind of membrane, which is cheap. According to statistics in 2003, 85% of car owners have put on this film. This kind of film is also the chief culprit of the so-called chaos, profiteering and inferior quality in the car film market.
2. Fake brand: This is a brand I hate most, which is obviously deceptive. Like the OEM film, the purchase channels of the film are Korean, Indonesian, Taiwan Province and other places, with three outstanding features: 1.
"Borrow chickens to lay eggs"
For example: Bosch film, Philips film,. Inducing customers with well-known brands has nothing to do with other brands. You know, Bosch and Philips have never produced car film. 2.
For example, when registering trademarks such as Johnson & Johnson Titanium, Johnson & Johnson 99, Dragon Film Supreme, Gu Wei Guangming, 3M Titanium, Infrared Quantum, etc., it is intended to add a few words after the names of big brands. This kind of film has nothing to do with other people's big brands.
How can we rationally analyze these branded films and counterfeit brands? It's actually quite simple. Just search the internet. A good brand must have roots! Although some brands are very loud, they actually don't exist abroad. There are many cases like Oudian floor in film products! The simplest way to identify him is to look at his official website, his foreign address and factory building. Some official website films are actually Chinese Pinyin, also called American films, which is very funny!
Pay attention to the film of Auto Parts City. It's difficult to distinguish between true and false movies. How can I choose a high-quality car film?
Before choosing the film, I will give you some training on some misunderstandings that must be understood before filming:
Myth 1: When choosing a dark-colored film, people often choose a dark-colored solar film in order to obtain better heat insulation and good privacy. In fact, the general "black paper film" and "tea paper" do not keep warm at all, and the thermal insulation effect of the film is determined by whether the film contains thermal insulation layer or not. Although the professional film is light in color, it can block 700 watts of heat in the scorching sun (solar radiation is 900 watts/square meter), while the low-grade dark film can only block 300 watts of heat.
Myth 2: Looking for infrared blocking rate
95% infrared blocking rate means 95% heat insulation? This is a wrong concept. Only 53% of the radiant heat of the sun comes from infrared rays, another 3% from ultraviolet rays and 44% from visible light. So even if a film can block 100% of infrared radiation heat, there is still 46% of solar radiation heat to be treated. Many car stickers are marked with 80% infrared blocking rate.
. . . The infrared blocking rate is 90%
At this time, don't walk into this misunderstanding. Attached is the formula for calculating the automobile film barrier ratio: thermal insulation ratio = automobile film infrared barrier ratio X53%+ automobile film ultraviolet barrier ratio X3%+ visible light barrier ratio X44%.
Myth 3: Stick two layers of film.
Sticking two layers of film usually leads to two problems. First of all, the adhesive design of the film is aimed at sticking to the glass, which cannot guarantee the perfect adhesion between the two films. Secondly, the second film may stick to the first film immediately, and it is too late to squeeze water. Usually sticking two layers of film is easy to produce bubbles and water bags, and these will become bigger and more with time. In fact, if you need a film to make the car darker, you can choose a film with low transmittance instead of two layers.
Myth 4: Insulation glass does not need to be pasted.
Insulating glass can only block some heat, but it can't resist ultraviolet rays. The special film for front bumper, such as dragon film and Gu Wei film, can block more than 99% harmful ultraviolet rays, block the large-scale entry of solar heat energy, reduce the harsh glare at night and create a good driving vision. The unique explosion-proof performance can ensure that the glass will still stick in place after being hit and broken by external force and will not splash around.
Here are several ways to choose car film:
1, clarity. The light transmittance of high-quality films can be as high as 70%, and objects 6 meters away can be clearly seen at night regardless of color depth, while inferior films will have a foggy feeling.
2, feel. Authentic film feels thick and smooth, while inferior film feels thin and brittle, which is easy to wrinkle;
3. color. The pigment of high-quality film is evenly mixed into the film, which is durable and not easy to change color, while the color of inferior film is in adhesive. After the lining of the car film is torn, it will fade when scratched with nails.
4. Taste. The residual solvent benzene in inferior film adhesive layer has high content and peculiar smell. You can tear off the protective layer of the film, and then smell the glue of the film. The glue used for regular film has no peculiar smell, just like the inferior car film, which is very fragrant. After sticking the film, the sun shines on the glass, and the smell will be bigger, which will also bring harm to the body.
5, bubbles. When the plastic lining of the car film is torn and reassembled, the inferior film will bubble, while the high-quality film will be intact after reassembly;
6. Shelf life. Generally, the films produced by regular manufacturers have a long shelf life, usually 5 years.
Pay attention to online film purchase and talk about online film purchase skills.
Generally speaking, online film is cheaper than physical stores, but car owners should also pay attention to online film purchase.
First, there is no warranty. Generally, the warranty period of a good automobile film is 5 to 8 years. Frequent phenomena such as foaming, curling and fading are all within the warranty scope. Film purchased online cannot provide after-sales service.
Second, buying movies online often buys fake movies, so you must be careful when buying movies online. So what are the skills of buying films online? Generally, there are entities selling films online. The best way is to contact online and then go to the physical store to shoot. This eliminates the above doubts. If you pay a high price for a fake membrane, it will not be worth the loss.
There is a saying in the film that "three parts film, seven parts construction", so how to choose a good construction shop,
Car enthusiasts have realized the necessity of car film. But finding a professional film is only half a good wish, because if it is inferior installation and service, it may not achieve the beauty effect you are pursuing, or even the opposite. ...
First, the special dust-free film pasting room-after the film pasting on the car window, there can be no defects and debris particles, so the professional installation must be carried out in the dust-free film pasting room! The clean room not only has a closed glass door isolated from the outside, but also has a water mist nozzle and air conditioner to realize air dust removal, and the ground has a drainage ditch and special paint to further realize dust removal. There is a dedicated workbench and articles in the room, which are neatly arranged. The installation effect under such a construction environment is by no means achievable by street open-air operation.
Second, professional tools-unprofessional tools such as shovels can't squeeze the water clean, leaving blisters and bubbles, which are more likely to scratch the film; Carbon steel blades may scratch high-grade automobile glass ... unprofessional shops usually use domestic or homemade unprofessional tools, which are rough in material and fuzzy in function, and often serve multiple purposes. Most of the professional laminating tools are imported from the United States, with clear classification, beautiful appearance and easy identification.
Third, special chemical liquid-professional automobile film should use special film cleaning liquid and installation liquid, and dilute with pure water, so that the film and glass can achieve the maximum bonding strength, and will not cause defects such as edge warping and delamination, and achieve long-term quality assurance effect. Non-specialty stores are using household cleaning agents, ordinary soap and tap water, which cannot provide professional installation and warranty period.
Four. Installation technology-professional film pasting technicians should receive technical training from manufacturers (the training certificate should be hung in the store), and the whole paving and dry heat setting process should be adopted when pasting the front and rear windshields, and the film should be pasted on the edge of the glass window as far as possible ... When pasting the front and rear windshields, non-professional installers should spray the car glass wet first, then spread the film on it, and then set it with a hot gun, which may cause excessive thermal stress and uneven heating to the glass, resulting in the glass breaking on the spot or within a few days after pasting.
Verb (verb's abbreviation) protection measures during installation-professional installation should take good protection measures: prevent the paint surface from being scratched by moisture during installation, damage the interior decoration, and cause short circuit failure of the electrical appliances and audio in the car; Avoid seat damage caused by window film installation and failure caused by accidental scratch or damage on the instrument panel surface.
Some suggestions on sticking film in 4S shop;
4S shop sends film when buying a car, is it ok? Well, it depends. If you don't pay attention, it's completely acceptable, but remember, the front gear is best not, because the films sent to you by 4S are generally not good films, and poor front gear films have a great impact on safety. It's best not to shoot, and the front gear can't stick bad films! If you have certain requirements for the film, you should make it clear when signing a contract with 4S that most 4S stores can provide high-priced film substitutes, but be careful not to blindly look at the brand, so if it is a brand film, it is necessary for 4S to provide an electronic warranty certificate, and also clearly know what film and model they posted for you! Because sticking fake film is more harmful! Some consumers also think that the film sent by 4S first can be replaced if it is not good. However, it should be noted that tearing the film after pasting the window film will cause some damage to the glass, which will reduce the clarity of the glass! So, if possible, grasp the following principles: either don't stick a film or stick a better film!
Appearance quality evaluation standard professional installation car film
(1) There should be no defects and sundries in the film, and there should be no creases and bubbles on the film surface; Stains, defects and sundries accumulated in the film are signs of low-quality installation.
(2) There should be only 1-2mm micro-gap at the top of the hem window, which is not easy to find by rough observation.
(3) The black glaze point area of the glass frame should be covered, without light leakage or edge warping, which is beautiful and harmonious.
(4) There should be no visual ghosts and watermarks caused by uneven extrusion force and irregular extrusion path.
Maintenance method of automobile film
A good movie needs careful cultivation.
Now almost all car owners will film their cars, but how to maintain the film has become a big problem. To this end, relevant experts said: try to avoid car washing within three days after the car film is attached, so as to avoid the car film falling off due to moisture. Try not to open the rear window defogging line for a week, because the moisture is not dry, which will easily cause adverse effects on the defogging line. After pasting, wipe the film surface with a wet towel, sponge or soft cloth. In addition, after a period of time, you will find that there is foggy water vapor inside. This is a normal phenomenon of solar film in the process of drying, and it will gradually disappear after a period of time.
Try to avoid lifting the window for a few days after the film is applied to the car (especially the new car that has just been coated). It takes 5-7 days for the solar film to be firmly attached to the window, so the edge of the film is easy to be smoothed and tilted during the opening and closing of the window, and the film that has not been fully bonded is also prone to displacement. High-quality car films usually have good wear resistance, and special high-performance resin adhesive is used between the films, which has excellent adhesion. It can be done that the edge of the film is only 2 mm away from the edge of the glass when sticking the film, and it is still not easy to wear. Moreover, the anti-scratch coating makes it have strong anti-scratch performance, long service life and easy maintenance. Lifting the window on weekdays is also easy to wear the film surface, and the inferior film will scratch in a month or two. Choosing high-quality car film can avoid this situation.
If you accidentally loosen the film when washing the car, you should go back to the professional film shop and let the professionals repair it again to ensure the effect and durability. If there are stains on the surface of the film, do not wipe it with chemical solvent. When cleaning, it is best to dip a wet towel, paper towel in water or cotton cloth with detergent, or wipe it with a rubber rag. However, abrasive products and tools that scratch or damage the film must be avoided to avoid damaging the solar film.
After pasting the film on the car, try not to paste or hang things directly on the window, so as not to pull the film out of the gap when pulling up the suction cup and the film.
