[China Glass Network] Inferior membrane is easy to induce chronic poisoning, respiratory diseases and cancer. Because the inferior solar film is low in materials and simple in process, it is not only easy to volatilize, but also contains high-risk substances such as aldehyde and benzene in materials and adhesives. During the driving process, these harmful substances will gradually decompose and volatilize, which will endanger the health of drivers and passengers. .
The second hazard of inferior membrane is that it is easy to make the driver's eyes fatigue, and serious traffic accidents will occur, endangering the safety of life and property of road participants. Some inferior membranes use ordinary inexpensive raw materials and curing processes, which are easy to produce light refraction and random reflection. In addition, the inferior solar film has a very limited effect of preventing glare and blocking ultraviolet rays, and because of the low light transmittance, it is easy for the driver to suffer visual fatigue and cause a traffic accident.
In such a chaotic market environment, how to choose a genuine brand of explosion-proof membrane is particularly important.
Fang Honglai, a person in charge in the industry, said that the method of identifying membranes is simple:
The first is hope. The merchant can be asked to cut a small piece of film down, take a photo of the bright place, the clarity of the film is high, and the inferior film looks foggy.
The second is smell. After tearing off the protective layer, the inferior film smells a pungent smell, while the high-grade film has a faint glue or basically no taste, which is related to the use of environmentally friendly glue.
The third is to touch. The high-grade film feels thick and smooth, and the inferior film is very soft and thin, not tough, and easy to wrinkle.
The fourth is rubbing. The surface of the film can be wiped with alcohol or gasoline, and the inferior film is easily faded.
The fifth identifies the anti-counterfeiting mark. High-end brands have clear, regular anti-counterfeiting signs. Inferior counterfeit film anti-counterfeiting marks are uneven and not clear.
In addition , consumers should pay special attention to the warranty card, and can enter the online certification center from the electronic warranty card system to obtain a warranty book to ensure the quality and maintenance of the thermal film.
