Is the darker the color of the car film, the better the thermal insulation effect?

There is no necessary relationship between the thermal insulation effect of the current automotive thermal insulation film and the color of the film. High-quality thermal insulation film can not only insult heat efficiently, but also ensure high light transmittance and ensure driving safety.First of all, it must be clear that too dark thermal insulation film may bring safety hazards because it will block the driver's sight.

The darker the color of the same type of film made by the same process, the better the thermal insulation effect and the better the privacy in the car.

In fact, there is not much correspondence between the color depth and thermal insulation performance of automotive films. The thermal insulation of automotive film mainly comes from the thermal insulation layer, not the dye layer. It mainly reflects the heat carried by the sun through the insulation layer to prevent the heat from entering the car.

A large part of the reason why many car owners choose dark film when applying film is that they think that dark film can block ultraviolet rays more effectively than light film. In particular, female car owners are afraid of the sun in summer, so they will default to dark film. However, it is not known that the thermal insulation effect of the car film is determined by the thermal insulation layer, not the staining layer.

Is thermal insulation sunscreen glass film useful

Car thermal insulation glass film is useful. The thermal insulation film of the vehicle can be divided into two types. One is the metal film, which uses the principle of metal reflection to reflect the infrared rays of the heat carried in the sunlight to achieve the effect of long-term heat insulation.

Car window film can insulate heat and protect the sun. The window film has seven functions, heat insulation and sun protection, and the film can solve the large amount of heat generated by infrared rays. Ultraviolet protection. The medium and long waves of ultraviolet light can penetrate thick glass. The thermal insulation film can block most of the ultraviolet rays, prevent skin damage, and also reduce the aging of the car interior. Safety and explosion-proof.

The function of automobile film is to increase aesthetics, increase private space, safety and explosion, heat insulation and sun protection, anti-glare, ultraviolet protection, and reduce air supervision and consumption. Can such a good car film really protect you from sun and heat? Good quality car sunscreen film does have the effect of sun protection and heat insulation.

Improve the indoor environment. Glass thermal insulation film can improve indoor comfort, reduce dryness and heat, and also weaken strong light and improve the indoor environment. Isolated from ultraviolet rays.

What are the precautions for replacing the car thermal insulation film?

x0dx0a Don't wash the car for three days. Due to the high water pressure of professional car wash equipment, water is easy to be penetrated from the edge of the window, which will cause a large water content of the edge of the glass and membrane. When lifting and lowering the window three days later, it is also easy to cause the edge of the Wrigley car film to fall off.

, avoid small impurities when applying the film. Generally, the whole car body will be cleaned before the film is applied. Before the film is applied, the interior of the car must be protected, especially the new car. Because the interior of the car will inevitably be dirty in the process of filming, it is necessary to do a good job of early protection. Cut the car film according to the size of the car window.

After the front bumper is pasted with the Wrigley film, try to expose the sun when parking during the day, which will make the front shield film dry faster.Generally, it will take about half a month to dry completely, including the rear gear. After the car is pasted with the car film, avoid lifting and lowering the windows within three days.

heat insulation and sun protection. The film can block the large amount of heat generated by infrared rays. Ultraviolet isolation. The medium and long waves in ultraviolet rays can penetrate very thick glass, and the thermal insulation film can cut off most of the ultraviolet rays. Prevent skin damage and reduce the aging of the car interior. Safety and explosion-proof.

Try to avoid washing the car within three days after the film is just applied, so as to avoid the film falling off due to the water before it is dry. Try not to open the defogging line of the rear window within a week. If the moisture is not dry, it is easy to have an adverse effect on the defogging line. After installation, you can wipe the film with a wet towel, sponge or soft cloth.

CarWhich brand of film has the best thermal insulation effect

The brands with the best thermal insulation effect of automobile film are Weigu, LLUMAR Dragon Film, Rui Dun, 3M, Meiji, etc. Weigu Shanghai Haiyan Weigu International Trade Co., Ltd., a well-known brand of glass film. One of the most competitive brands in the world automotive thermal insulation film market, it is an intelligent glass film that can screen the spectrum in the world.

Dragon Film: Dragon Film is a high-performance architectural glass film brand that attracts much attention in the world, and its products are widely used all over the world. 3M: 3M is a world-renowned diversified multinational enterprise, and its automotive film products are loved by consumers. Strong and Strong: Its products have the advantages of high definition, high thermal insulation rate, low reflection, etc., and are deeply loved by consumers.

The best thermal insulation effect of automobile film brands is 3M automobile film, Hongsong automotive film, Meiji automobile film, etc.You can listen to the sound to judge whether the car film is good or bad, and then listen to the sound of the car model. If the car model makes a crisp sound, the car film may be made of high-quality materials.

Then_, which brand of vehicle solar film is better? Let me take a look at the sun film ranking list below with you.

Can a good car film really protect you from the sun and heat

1. The window film can protect you from the sun. The window film has seven functions, heat insulation and sun protection, and the film can solve the large amount of heat generated by infrared rays. Ultraviolet protection. The medium and long waves of ultraviolet light can penetrate thick glass. The thermal insulation film can block most of the ultraviolet rays, prevent skin damage, and also reduce the aging of the car interior. Safety and explosion-proof.

2. The automobile film can really insulate heat. The thermal insulation effect of the automobile film is not directly related to the color shade. The coating process in the automobile film is the key factor in determining the thermal insulation effect of the automobile film. For example, the magnetron sputtering process of Weigu automobile film, in addition to the excellent thermal insulation effect, also has Anti-glare, anti-ultraviolet and other effects.

3. The sun protection effect of the car film is really good, so I like to use this brand of car film, which can not only block ultraviolet rays but also block infrared rays and ultraviolet rays, so it is particularly good. What car owners can't stand most in summer is driving in the scorching sun. This is not only hot. At this time, it may not be enough to turn on the air conditioner all day.

4. [Pacific Automobile Network] Car film sunscreen, high-quality thermal insulation film can effectively block the ultraviolet rays in the sun and permanently protect the skin of the people in the car from ultraviolet rays.The ultraviolet barrier rate of Weigu thermal insulation film is 99%, and the SPF of the sun protection index is as high as 200+.

5. The solar membrane can insulating heat. Thermal insulation film, also known as solar film, can insulated heat. The composition and function of the solar film are as follows: The composition of the solar film: The solar film is a kind of car film developed to cope with summer sunlight and ultraviolet rays. The current solar film is a multi-layer dense metal film made of gold, aluminum, silver, nickel, titanium and other rare metals.

6. A good car film can be explosion-proof and prevent ultraviolet rays. Ordinary is fine.
