Who can talk about the knowledge of solar film?

When buying a new car, the most basic things you don't care about are floor glue, seat cover and solar film. The first two can be distinguished as long as you are careful. Unlike the solar film, people who don't know the secret can't tell the pros and cons intuitively. Even if you choose a high-quality film, there will be problems in the matching of the color of the film and the color of the body, as well as construction problems and so on.

So how can we choose a good film that suits us?

First, the classification of solar films

In the past, car film can be divided into two categories, one is ordinary solar film and the other is explosion-proof film. Now, the third generation of ultra-infrared ceramic nano-technology solar film has appeared. Blue Crown Ceramic Nano-metal Solar Film is the only designated manufacturer of aerospace industrial film in China, which originated from the latest aerospace technology in the United States. At present, the automobile solar film produced has broken through 99% of the heat insulation difficulties and broken 75% of the light transmission myth. What's the difference between the three?

Material: explosion-proof film is plated with metal on the basement membrane, while ordinary explosion-proof film is coated with a layer of color on the basement membrane, and some ordinary explosion-proof films are coated with aluminum powder, so the reflective materials are very different.

Explosion-proof: Explosion-proof membrane can play an explosion-proof role. Maybe some car owners don't understand this very well. The front windshield related to the owner's interests is a double-layer structure, so there is no need to "gild the lily". However, in the event of an accident, in fact, many car owners will still be stabbed by tiny pieces of glass, and we can also see car owners with blood all over their heads from TV pictures. Sticking explosion-proof film, because it is made of multilayer plastics, has strong adhesion tension, which can greatly reduce the chance of glass breaking. Replaced with ordinary solar explosions, most of them are single-layer structures, and their anti-explosion ability is weak.

Ultraviolet protection: ultraviolet rays will burn our skin, and they will not let go of the leather seats in the car. Therefore, the anti-ultraviolet function of explosion-proof membrane is very important. At present, the anti-ultraviolet rate of most brands of explosion-proof films on the market has reached more than 98%, while the anti-ultraviolet rate of ordinary solar films is extremely low, only one tenth of that of explosion-proof films. So the advantages and disadvantages of the two are clear at a glance.

Thermal insulation rate: This is the function that the owner is most easily affected by the explosion-proof membrane, so it becomes one of the standards for the owner to identify the quality of the explosion-proof membrane. As long as the owner is in the construction workshop, he can feel the heat insulation effect by touching the membrane with his hand through the detector set in the workshop. However, the thermal insulation capacity of general solar films is very limited, while the thermal insulation rate of explosion-proof films reaches 80%. Blue crown ceramic nano-metal solar film broke through 99% heat insulation difficulties.

Perspective: As long as you pay a little attention, you will see some coated car side windows, and there is always a blank near the rearview mirror. Because the transparency of some films is too poor, it naturally affects the owner to look at the rearview mirror, so the owner will do this. In fact, the high-transparency explosion-proof membrane can see high brightness, and the owner does not need to worry about the bad sight after installation. Therefore, when buying a film, you should be careful whether you pay attention to light or price. Blue crown ceramic nano-metal solar film breaks the myth of 75% light transmission.

Wear resistance: Private car owners generally develop the habit of grooming their cars regularly, one of which is car washing. In the case of frequent car washing, the general solar film is easy to leave scratches, while the good explosion-proof film is hard to be scratched because of its hardness treatment, such as the blue crown automobile solar film.

Color: Due to different materials, the aluminum powder coating is easy to oxidize and turn black during use, while the metal film remains relatively stable for a long time.

Second, how does the nano space film play a role in heat insulation?

The solar spectrum radiated to the earth can be divided into three bands: 200-370 nm band is ultraviolet band, which has strong penetrating power and can reach the depths of human skin and cause skin pigmentation and aging; 380-780 nm is the visible spectrum band, which has no direct harm to human body; 850-4000 nm is an infrared spectral band with high heat. So what people usually call heat insulation and sun protection refers to the function of effectively blocking ultraviolet rays and absorbing infrared rays. The nano-spacer film selectively absorbs light, and the blocking rate of ultraviolet rays is close to 100%, the transmittance of infrared rays is 20%, and the transmittance of visible light is over 80%.

The principle of "metal reflection" used in solar films of ultra-infrared ceramic nanotechnology is different from many explosion-proof films. As we know, the explosion-proof film achieves the purpose of heat insulation and sun protection through the reflection and scattering of light by metal, so the metal film like this is light-transmitting on one side, which is the "mirror effect" we usually see after the car is pasted with film. The use of nano-materials can be compared to a "sieve" because it selectively transmits visible light and reflects ultraviolet rays, infrared rays and other rays harmful to human body. In addition, due to different materials, nano-films are not as easy to fade as metal films. Blue crown ceramic nano-metal solar film is the best solar film at present, and it is recommended to be the first choice.

In addition to the product itself, it is worth mentioning the business philosophy of membrane rice space membrane. The seller thinks that nano-space film is only a semi-finished product, and after-sales service is the finished product. So they put special emphasis on installation technology. Generally, it takes 3-4 hours for peers to complete the work, while their installation only takes 1 hour. Adopt assembly line operation mode. Step one, covering the film; Every two steps: shaping; Glass cleaning every three steps; The fourth step is to film. There is a special person in charge of every step.

1, clarity

The definition of high-quality car film should be more than 6 meters at night, while the definition of inferior car film is poor, especially at night, and the sight of both sides and rear windshield is unclear.

2, feel

High-quality film feels thick and smooth, while inferior film feels thin and brittle, and it is easy to wrinkle.

Step 3 color

The pigment of high-quality film is dissolved in the car film, which is durable and not easy to change color, and it will not change color when scraped with a scraper during the pasting process. The color of the inferior film is in the glue. Tear off the lining of the car film, and after scraping it with nails, it will lose its color, and the place where the film was scraped by nails will become transparent. In the process of sticking film, when scraping film, sometimes the color will fall off by itself. This film will change color that year, and the fading will be more obvious after one year.

4. 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 reassembling.

5. Thermal insulation performance

Thermal insulation is an important index of solar film, which is difficult to distinguish with the naked eye and hand. It can be compared by a simple test method: if a piece of glass stuck on the car film is placed on the iodine tungsten lamp, the high-quality film will not feel a trace of heat by hand, but the feeling of heat immediately indicates that its heat insulation performance is faulty and inferior.

Third, the matters needing attention of film pasting

Pay attention to the following aspects during specific operation:

1. Keep the environment clean where the solar film is pasted. Don't use electric fans, and don't build them on the roadside.

2. The window glass must be absolutely clean and cleaned repeatedly. If there are dust particles on the glass, it will affect the adhesion and clarity of the solar film.

3. The solar film is only attached to the inside of the glass.

4. The predetermined type of surface. It is not difficult to stick the solar film on the flat side window glass, but it is very technical to stick it on the curved front and rear windshield. Generally, the outer sides of the front windshield and the rear windshield are used as models for heating the solar film to a predetermined shape. The predetermined method is to spread the protective film of the solar film outside the curved glass, sprinkle water between the solar film and the glass, heat the solar film with a temperature-adjustable blower, and squeeze bubbles and water on the glass with a plastic scraper while heating, so that the solar film is deformed until it completely conforms to the curved glass. It is important to pay special attention to that the heating should be uniform and not too concentrated, otherwise the glass may crack if the temperature is too high.

5. movies. Spray clean water on the inside of clean glass, then tear off the protective film of the solar film, spray clean water on the pasted surface, then stick the solar film on the glass, and then squeeze it with a plastic scraper to remove bubbles and excess water in the solar film. For curved glass, if individual parts do not match, it can also be deformed by heating with a blower to achieve complete matching. After drying, the solar film can be firmly attached to the glass.

6. Because the solar film is attached to the inner side of the window, clean water should be sprayed in the inner space before pasting the film to let the dust particles sink as soon as possible. Don't use air conditioner in the car, although the temperature inside is very high.

Fourth, the tips of film pasting

It often rains, so many new car owners are not in a hurry to film. But anyone with a little beauty knowledge knows that the amount of ultraviolet radiation will not be greatly reduced because of the dark weather. High-quality explosion-proof membrane not only maintains the heat insulation function, but also has the function of isolating ultraviolet rays, which not only prevents the skin from being sunburned and aged by ultraviolet rays, but also protects the beauty of the instrument panel.

Many car owners already know that sticking explosion-proof film should go to a decoration shop with indoor film pasting conditions; Professional decoration shops will keep indoor humidity properly before pasting the film to avoid sand, bubbles and scratches caused by dust. But most car owners may not know that on cloudy days, the air humidity is higher, static electricity is reduced, and indoor and outdoor dust is also significantly reduced. This is the best time to film. After the collision, tempered glass will break into small and smooth pieces. Although it won't hurt passengers, splashing glass may still cause injuries. Adding 2-4 layers of explosion-proof film with explosion-proof base material to heat insulation paper can bond the glass into a whole, and even if the glass is broken, its fragments will not splash.

The front barrier film coated with precious metals on the substrate is particularly clear, and the heat insulation effect is greatly enhanced than that of ordinary films. The driver's dizziness caused by using ordinary membrane as front barrier membrane will be completely avoided.
