Some car owners think that it is a fake, as long as the price is cheap and can maintain the car.
But the facts are often terrible: fake and inferior car solar film can not only maintain the car, long-term use will also hurt their health! The low cost of the fake film is staggering, and the so-called cheap price is nonsense.
Don't believe it, there are many cases of fake membranes on the Internet. Xiao Bian hereby collects some "pre-cars" to uncover the "veils" of the inferior solar film dark horror for the owners.
First, the heat insulation rate is low
Case: Although the solar film is attached, Mr. Li’s car is like a hot steamer in the summer. Only the air conditioner is opened, which has caused several illnesses due to air-conditioning last year.
Analysis: Generally, the thermal insulation rate of regular solar film is 30% to 40%, even if the price of two or three thousand film insulation can only be 50%-60%.
Some solar film manufacturers claim that their solar film insulation rate can reach 80% or even 90%, most of them are "Hu Kuafeng."
Uninsulated car film, under the sun exposure, will make the car temperature too high, which will affect the driver's operation, and the long-term exposure of ultraviolet light will also hurt the car interior and sunburn the car.
Second, the glass absorbs heat
Case: Miss Wang has been unable to understand that her car has become very hot since the sun film is attached, and it is almost possible to brand pancakes.
Analysis: The industry judges that Miss Wang may have encountered a full absorption film. Regular solar films are generally both reflective and absorptive.
In order to save costs, some inferior membranes adopt the method of adding absorbents in whole or in large quantities, so that the heat is absorbed on the glass, and of course it is hot.
In addition, the absorption efficiency of the absorbent is easily attenuated, and the heat insulation effect is greatly weakened in about 1 year.
Third, no front film
Case: Mr. Li film, the business only posted the body film, no front film, if you paste it, you can only use other brands.
Analysis: At present, there are not many brands of solar film that can provide the front film on the market, because the light transmittance of the front film must reach 70%, and at the same time, it must take into account the high heat insulation rate, and the two "home-to-head".
To coordinate their relationship, the manufacturer's manufacturing process requirements are very high, and the price is naturally high, so many inferior membranes basically do not provide the front film.
However, consumers should be wary that some inferior membranes may also provide some front film with a very good heat transmittance but a very low heat insulation rate.
Fourth, irritating smell
Case: Mr. Wu’s car will always give off an unpleasant smell after being grilled by the sun.
Analysis: This may be related to the poor quality of the glue used in the solar film. In addition, the poor quality of the glue can also lead to insufficient adhesion and poor explosion resistance.
The quality of inferior membrane colloid is very poor. The membrane attached to the inner side of the window will gradually release high-risk substances such as formaldehyde and benzene in the case of long-term closure or sun exposure. It is easy to induce chronic poisoning and respiratory diseases, causing damage to human health.
It can cause chronic respiratory diseases, eye diseases, and chronic poisoning, and may even cause cancer!
Fifth, serious light pollution
Case: Mr. Yu had a car accident last summer, a sharp bend. The glass of the opposite car reflected a strong light and completely swayed his eyes. As a result, he drove into the small ditch next to him.
Analysis: The regular film has low requirements for the visible light reflectance, and some inferior films are very high, causing a lot of glaring "light swords" on the street, forming light pollution.
Cheyous know that driving is more important to watch the road, and the blurred vision is dangerous!
Inferior membranes mostly use ordinary cheap raw materials and curing processes, which will partially melt under the sun, produce optical distortion, hinder the driver's sight, and even cause traffic accidents, endangering the safety of life and property of road participants.
