At present, there are many car film brands on the market, and the prices are far apart. Many car owners often look around and make up their minds. In fact, a good car film is also a high-tech product, and there is a lot of knowledge in choosing a car film. Sticking film requires high technology and soft and hard conditions, such as dust-free environment, special equipment, standardized operation process and skilled technology. However, due to the extremely low threshold for joining this ranks, some unscrupulous traders are involved, and counterfeit and shoddy products are rampant, and consumers often suffer losses because they don't know how to do business. In addition, there are hundreds of car beauty shops in Shenzhen at present, and almost every one sells car films, which undoubtedly increases the difficulty for consumers to choose.

Knowledge article

Since the automobile film was put on the market, it has gone through three stages: tea paper, explosion-proof film and sun-proof heat-insulating film.

"Tea paper" is the first generation product, commonly known as sun paper, which is characterized by strong shading and simple installation. The disadvantage is that it is not insulated and is easy to fade and degum. "Explosion-proof membrane" belongs to the second generation product. The explosion-proof effect is improved by using new adhesive and thick film layer, and it has certain heat insulation and sun protection performance, with heat insulation rate of 20%-60% and ultraviolet shielding rate of about 80%. Sun protection and heat insulation film belongs to the third generation products, also known as heat insulation paper, space film and so on. Many new technologies are adopted, such as magnetron coating, micron technology, nanotechnology, spectral particle technology and so on. , can effectively block more than 90% of ultraviolet rays, improve the infrared blocking rate to about 30% ~ 95%, and make the adhesive more sticky, thus achieving the following purposes.

Selected articles

When purchasing automobile film, several performance indexes closely related to quality can not be ignored.

One is the transparency and clarity of the film.

This is the most important performance of automobile film related to driving safety. Users are advised not to choose films with too low transmittance as far as possible. It is more appropriate to choose films with transmittance above 85% for window films, especially for the first two windows. At this time, the side window film does not need to be dug, which does not affect the line of sight. When driving at night, it can also reduce the strong glare reflection of the oncoming car headlights on the rearview mirror, making the eyes very comfortable. In addition, good sight can be ensured when driving, reversing and turning around on rainy nights. Second, thermal insulation performance. Thermal insulation rate is an important index to reflect the thermal insulation performance of window film. Considering the climatic factors of long summer, high temperature and strong sunshine in Guangdong, the thermal insulation performance of window film is higher. Good quality automobile explosion-proof membrane can reflect infrared rays, so the temperature inside the car is much lower, which in turn will reduce the air conditioning load and save fuel. If the car is the main judge, the method is simple, just block the sun with coated glass and feel its heat insulation effect with your face or hands.

The third is explosion-proof performance, which is another important performance related to safety. High-quality explosion-proof film itself has strong toughness, and the glass can be stuck by the film after being broken, and it will not splash and hurt people, so it has strong impact resistance. Inferior explosion-proof membranes are soft to the touch, lack sufficient toughness, are not resistant to ultraviolet radiation, and are easy to age and become brittle.

The fourth is the ultraviolet blocking rate.

For high-quality membranes, this index is generally not less than 98%, and the high one can reach 100%. The ultraviolet blocking rate is high, which can effectively prevent people in the car from being burned by excessive ultraviolet radiation, and can also protect the car stereo from sunburn. Many inferior membranes do not have this index, or are far below the standard of 98%.

The fifth is color.

Colors can be matched according to body colors and personal hobbies. Usually use light green, sky blue, gray, brown, natural color and other colors that are more comfortable for the eyes.

Sixth, the film surface scratch-resistant layer.

The high-quality and high-grade film surface has a scratch-resistant layer, which can protect the film surface from being scratched under normal use.

Seven is the shelf life.

Generally, the films produced by regular manufacturers have a long shelf life, usually 5 years. Some high-quality films have a shelf life of up to 8 years.

Installation items

Many car owners already know that the film is going to a regular car decoration shop, but most car owners may not know that it is cloudy, the air humidity is high, and the suspended matter in the air is obviously reduced, which can avoid the impurities between the film and the glass from affecting the appearance. This is the best time to film.

Movies are afraid of dust. Once there is sand or fine dust stuck between the film and the glass, the quality and effect of the whole film will be affected. Therefore, we must choose a car service provider with a closed workshop. In addition, the front and rear windshields can best test the technological level of film pasting, which adds a lot of difficulty because of its large curvature and large area. So don't be greedy and cheap, try to choose a large-scale and reputable car service provider to add a truly safe and effective barrier to your car.

Cleaning the glass is the basic work of the quality of the mounter. There are generally three steps in cleaning glass: glass inspection, removing rubber particles and gravel; Glass dust removal and cleaning (due to the need for water dust removal and lubrication, pay attention to prevent water from leaking into the car audio and electronic control system, and must be cleaned three times); Cleaning before pasting. When cleaning the rear windshield, carefully protect the heating wire.

When asking the store to stick the front and rear windshields, it is best not to cut the operation, but to stick them as a whole, otherwise they will lose their explosion resistance and affect their appearance.

After filming the whole car, sit in the car and observe whether the color is even and whether there are too many bubbles or stones. And looking out from various angles will not affect the line of sight.

General car decoration shops usually pack a box with glass and infrared light source inside, and then stick a film on the glass surface to create a simulated sunshine environment. High-quality car film can obviously block thermal radiation, which can be judged by the feel outside the box.

A good membrane can normally be used for 5 to 6 years. Some brands of film have a film warranty card, remember to ask the merchant for it; Moreover, films without warranty cards must also keep all kinds of documents and invoices, so as to find a business "theory" when problems arise.

With the gradual increase of temperature, shops selling fake car films in the market are also ready to move. Car owners must be careful when choosing, so as not to be deceived. Generally speaking, the following kinds of car films are favored in the market:

1, Gu Wei: Needless to say, it is an expensive membrane recognized in the market at present, and its heat insulation effect and ultraviolet protection effect are really good. Aside from the price factor, its film is soft and its scratch resistance is not very good. Everyone knows the side window of the new Accord.

Due to the large curvature, it is easy to cause serious scratches on the film.

Advantages: good heat insulation effect, good anti-ultraviolet effect and few fakes.

Disadvantages: Soft texture, poor scratch resistance and high price.

Price: the front gear and the car body should be able to draw a price of 2500-3000 yuan, which is not worth it.

2. Johnson & Johnson: The price/performance ratio is good, but now fakes are rampant in the market and it is difficult to distinguish. Johnson & Johnson's new security label was copied. However, Johnson & Johnson has a hard texture and good scratch resistance.

Advantages: good cost performance and good scratch resistance.

Disadvantages: There are too many fakes to distinguish.

Price: the front gear plus the body should be around 2000 yuan.

3. Ray-Ban: Many users, good quality, but few real goods.

Advantages: good transparency and various colors.

Disadvantages: There are many fakes on the market.

Price: the front gear plus the body should be around 2000 yuan.

4. Sony: Although its popularity is not very high, its cost performance is good and its transparency is good. The most important thing is that there are not many fake and shoddy products.

Advantages: good cost performance, good transparency and few fakes.

Disadvantages: short shelf life, only six years.

Price: front gear plus body 1200 yuan.

5, 3M: The same fake film is everywhere, with less color, but the real film is also a classic, and the effect of filtering ultraviolet rays is also good.

Advantages: Classic color.

Disadvantages: too many fakes, less colors and poor scratch resistance.

Price: front gear plus body is about 2000-3000 yuan.

6. Yuma: This brand belongs to the mid-range. Because it entered the market late, its popularity is not very high, but its effect is good and its scratch resistance is also very good. At present, the manufacturer has controlled the supply and only delivers goods to authorized stores. Basically, there are few counterfeit products.

Advantages: good cost performance, good scratch resistance, verified by authorized stores and factories, and few fakes.

Disadvantages: short shelf life, only six years.

Price: front gear plus body 1200 yuan.

7, Dragon Film: This brand is rarely mentioned, but the quality is really good, but because it has just entered the market and the price is high, the sales volume is not very good, and there are very few agents who make this brand.

Advantages: Good user response quality.

Disadvantages: there are few dealers and it is not easy to find.

Price: 2500-3000 yuan
