Dark film and light film, how to choose automotive glass film?

The color of the car glass film is better in light color. Generally speaking, if the quality of the film is distinguished by color, the transparent film is stronger. However, some drivers don't like transparent film very much, and film manufacturers also produce color film. In general, there is carbon black.

Dark gray, grass green to dark ivory, light ivory, etc. , even if there is no color transparent film, there is actually a difference in shade. Picking a color or a dark film that suits you does feel more comfortable in the obvious sun, but on a rainy day.

And at night, be sure to make sure you have a clear view and <>

Otherwise, it may seriously endanger the lives of others and damage your own driving. It's not just dark car films that insulate well.

Some businessmen claim that this kind of dark film has a good practical effect of thermal insulation and can maintain the owners of the community. In fact, the actual effect of the thermal insulation of the membrane lies in the heat transfer coefficient in the membrane.

layer, not the dye layer. The purpose is to reflect the surface sunlight according to the heat transfer coefficient layer.

Bring on the calorific value.

This prevents heat from entering the car. Therefore, when choosing a glass film, you need to pay attention to the quality of the glass film, and then choose your favorite color.

Even if there is no color of the transparent film, in fact, there is a difference in the shade, moderately choose the colored plate or a darker car film can indeed feel more comfortable under the obvious sunshine, but we must ensure that the vision is clear in rainy days and nights, otherwise it is likely to seriously endanger the life safety of others, and it is not conducive to driving. And it is not the actual effect of dark car film insulation, some businesses confuse drivers with the view that the dark car film has a good thermal insulation effect, in fact, the heat insulation effect of the car film is good or not lies in the heat transfer coefficient layer in the car film, <>

Instead of coloring the layer, the key is to develop a reflective surface of the heat energy in the solar zone according to the thermal insulation layer, and then block the heat from entering the car. Therefore, when choosing a car film, you should pay attention to the quality of the car film, and then choose your favorite color. There are many drivers who choose dark films in the case of glass films, and a large part of the reason is that they feel that dark films are more effective at blocking UV light than light films.

However, I don't know that the actual effect of glass film insulation is actually not very related to the color of glass film, and the actual effect of heat insulation is determined through the heat insulation layer, so in view of this, I would like to remind you in particular.

The car glass film should choose a light-colored film is better, because the light-colored film has the least impact on the sight, so that the driver can clearly observe the driving road conditions and the surrounding situation, which is conducive to safe driving, if you pay special attention to privacy, you can make the side door glass slightly darker, but the front windshield must choose a light-colored one.

Depending on the situation, if it is a car window, you can choose a dark film, because the dark film is more effective than the light film to block ultraviolet rays, and for the privacy in the car, the dark film can also better protect the privacy in the car. If it is a front windshield, it is recommended to choose a light color, because if the windshield uses a dark film, it will seriously affect the owner's vision and cause potential safety hazards.

I think you should choose a light film because a dark film can affect the driver's vision.

Generally speaking, the quality of the car film is divided according to the color, and the transparent car film is better. However, some car owners don't like transparent car films, and car film manufacturers also produce colored car films.

It is generally charcoal black, dark gray, olive green.

to dark natural colors, light natural colors, etc. Even if the so-called colorless transparent film, in fact, there is still a difference between the shades, and the appropriate choice of colored or darker car film can indeed feel more comfortable in the strong sunshine, but it is necessary to ensure that the sight is clear on rainy days and at night, otherwise it may endanger the personal safety of others, and it is not conducive to driving.

Precautions for automotive glass film.

It is important to note that the car should be washed as much as possible for two to three days after the film is applied. Because car washing will cause car film.

Blistering and even the film comes off. After that, you can wipe the surface of the membrane with a clean and soft wet towel, sponge or soft cloth, or you can use a rubber wiper to avoid scratching the surface of the membrane.

Remember not to clean with corrosive solutions that contain alcohol or chemical solvents, as this may cause the film to fall off, and avoid using hard tools that can cause the film to peel off.

The light transmittance is greatly reduced, and even scratches or damages the car film.

Is it better to have a dark or light color for car glass film? The color of the car glass film is better in light color. 1.

Generally speaking, if you divide the quality of the film by color, the transparent film is better. However, some car owners do not like transparent film, and film manufacturers also produce color film. In general, there are carbon black, dark gray, olive green to dark natural color, light natural color, etc.

Even the so-called colorless transparent and Hui Jingming films, in fact, there are differences in shades. In strong sunlight, choosing the right color or dark film will indeed make people feel more comfortable, but in rainy days and at night, it is important to ensure that the line of sight is clear, and the blue sedan may endanger the personal safety of others and is not conducive to your own driving. It's not just a dark car film with good thermal insulation.

2.Some vendors claim that this dark film has a good thermal insulation effect and can protect the owners. In fact, the thermal insulation effect of the membrane depends on the thermal resistance layer in the membrane, not the dye layer.

The heat carried by the sun is mainly reflected through the thermal resistance layer, which prevents the heat from entering the car. So when choosing a film, pay attention to the quality of the film, and then choose the color you like. @2019

Transparency: This is the most important manifestation in vehicle movies related to driving safety. It is recommended that users try not to choose films and window films with too low transparency, especially the films on both sides of the front window, and the substrate used in the front window film should also be clear enough.

Even if the film is darker, the scenery they see should be transparent and not dull or distorted. It is more appropriate to choose the light transmittance above 85%. At this time, the side window film does not need to be dug to affect the line of sight.

When driving at night, it can also reduce the strong glare reflection of the headlights from the rear on the upside-down mirror, making it very comfortable for the eyes. In addition, it can also ensure good visibility when driving, reversing, and making U-turns on rainy nights.

Thermal insulation rate: High-quality car explosion-proof film can reflect infrared rays, so the temperature in the car is much lower, which in turn will reduce the no-load adjustment and save fuel. If you judge by the car, the method is very simple. Simply block the sun with a glass cladding and feel the insulation with your face or hands.

After the glass is broken, it can be bonded by the film, which will not splash and hurt people, and has strong impact resistance. However, the inferior explosion-proof film is soft to the touch, lacks sufficient toughness, is not resistant to ultraviolet radiation, and is easy to age and brittle.

Ultraviolet blocking rate: For high-quality film, this index is generally not less than 98%, and the high can reach 100%. The high UV blocking rate can effectively prevent the occupants of the car from being exposed to excessive ultraviolet rays and burns**, and can also protect the in-car audio from sunlight.

However, many low-quality movies do not have this indicator, or are well below the 98% standard. This is also the main basis for the warranty period of the product.

First, when choosing a car film, you should first understand what are the functions of the film and why you should apply the film.

Function 1: Heat insulation. Car film can block 78% of the sun's energy.

Effect 2: Slow down fading. It has a higher ability to block ultraviolet rays and slows down the fading of interior decorations and items. (In fact, ordinary glass can block 90% of ultraviolet rays).

Effect 3: Reduce glare entry and improve driving safety.

Function 4: It has a certain ability to reduce temperature and reduce the energy loss of air conditioning.

Function 5: Increase safety, can bond the broken glass film together, and prevent glass fragments from hurting people during vehicle collisions.

2. How to choose a car film.

1. Explosion-proof performance: The material of the general film or inferior explosion-proof film is different from the real explosion-proof film, the film is very thin and soft, lacks sufficient toughness, is easy to age and brittle, and cannot play an explosion-proof role when encountering accidental collisions. **The explosion-proof film will be bonded by the film after the glass is broken and will not splash.

2. Light transmittance and clarity: This is the most important performance of the car film related to driving safety, some colors are very dark, the light transmittance is very low, and the film is black and whirring, and a hole must be dug in the side window film to see the rear mirror, which is quite dangerous for driving safety. The best film, regardless of the color shade, the clarity is very high, not only can the strong glare reflection of the rear headlights shining on the rear mirror when driving at night is weakened, but also in the rainy night driving, reversing or turning around is also good.

3. Thermal insulation performance: the thermal insulation rate is an important indicator that reflects the thermal insulation performance of the explosion-proof film of automobiles, and the explosion-proof film such as dragon film, AC Deco, Ray-Ban and so on the market generally has a thermal insulation rate of more than 50%, high light transmittance and high thermal insulation, which can not only improve the comfort of driving, but also reduce the air conditioning load to achieve the purpose of fuel saving. On the contrary, many membranes only have light transmittance but no thermal insulation rate, and some even have no indicators at all.

Therefore, in addition to seeing whether the thermal insulation rate and other indicators are standardized, the safest way is to block the sun with the glass of the film or irradiate it through an iodine-tungsten lamp, and directly test the thermal insulation effect with your face or hands.

4. Product warranty: quality assurance includes no fading, no foaming, no peeling, no falling off, and no scratches during normal use. The shelf life of automotive film should be long enough, at least more than five years, some up to more than 8 years, and the GSN film of Johnson (Johnson & Johnson) film is a lifetime warranty.

3. Other matters that should be noted.

1. The first is to choose the brand, the manufacturer of the famous brand has a complete set of quality assurance system, the products have been strictly inspected and tested before leaving the factory, and the index data provided on the promotional materials are accurate and credible. Famous brands not only have good quality, but also have a perfect after-sales service system.

2. There is also a big store, only the big store has the strength to distribute brand-name products, quality assurance, and film technology and conditions. Ask for a quality assurance card, and be sure to fill it out completely, and keep it with the official invoice, you are a smart consumer!
