[China Glass Network] The inferior glass film has many hazards. The homeowner may think that even if you accidentally buy inferior goods, it is a big deal to lose some money. In fact, the inferior thermal insulation film implies many ills. The following is the ultra-film studio expert to answer some questions about the inferior membrane damage.
First, the chemical glue layer absorbs heat, causing hidden dangers of glass
There used to be a film that sold very hot in Beijing, but it has almost disappeared. I heard that it was a boycott of dealers because of quality problems. One of the main problems is that the film is easy to cause glass to burst. After such a test, the sample plate was baked under the lamp, and it was found that the film plate was quickly warped and deformed, and then the test was performed, and the effect was not as good as before. This is a typical endothermic film. Its characteristics are as follows: First, the chemical coating agent changes after heating, so that the original efficiency is gradually lost. Second, the absorption of heat makes the glass temperature too high, and the long-term thermal expansion and contraction eventually leads to The glass burst.
Second, the clarity is reduced, which is harmful to driving safety.
The traffic safety regulations of the Ministry of Public Security clearly stipulate that the light transmittance of the front windshield must be greater than 70%. Frankly speaking, the film has some influence on the front windshield line of sight, but the degree of influence of the high quality film is inferior to that of the inferior film. High-quality membranes will strictly enforce the standard of light transmission, try to reduce the impact to a low level and neglect it, and one of the hidden dangers of inferior membrane is that the transmittance does not meet the standard. This is why some cars feel blurred after the film is applied, especially during rainy nights.
Third, residual volatile substances, endangering human health
One of the inferior membranes is a dyed film. I believe many of my friends have seen the dye and smelled the smell. The chemical coatings in these stain layers will cause pollution inside the car and damage human health.
Fourth, blocking UV is not up to standard
The harm of ultraviolet rays cannot be seen by the naked eye. The inferior glass film can not effectively block the ultraviolet rays. The promotion is exaggerated, and there is basically no such function, which is harmful to the health of consumers.
Cheap, no good goods, I hope consumers can polish their eyes, for the health and safety of you and your family, buy genuine glass film.
