&Recently, it has been exposed that the three major luxury car brands, Mercedes-Benz, BMW and Audi, use asphalt damping sheets, resulting in serious air quality pollution in the car. However, car owners have frequently complained to no avail. For a time, damping film became a hot word. So, what exactly is a damping sheet? Is it highly toxic or carcinogenic? For this reason, Wenzhou Second-hand Car Mall Network reveals the true face of damping sheets for car enthusiasts. & %Asphalt damping is used in family sedans
The damping sheet is a viscoelastic material attached to the inner surface of the car body. It is closely attached to the steel plate wall of the car body and mainly plays the functions of shock absorption, noise reduction, heat insulation, etc. Damping sheets are installed in almost all cars on the market. Damping sheets are used under the floor, on the side panels, in the trunk, etc., with a total area of about three square meters. In addition, damping sheets are also used in aerospace vehicles, aircraft and other machinery that require vibration and noise reduction.
At present, in developed countries with the automobile industry such as Europe and the United States, automobile damping sheets generally use polymer resin materials or rubber materials, such as butyl rubber (chewing gum contains this ingredient). As raw materials, they have stable physical and chemical properties, excellent shock and noise reduction properties, heat resistance, cold resistance, anti-aging properties and strong adhesion. It has no irritating effect on human skin and has no corrosive effect on metal, plastic, rubber and other materials. As many as % of domestic models in the Chinese market, as well as a considerable proportion of imported models, use asphalt or asphalt-based damping sheet materials, which weigh about kilograms.
This is actually a traditional process. In addition to the common use of asphalt damping sheets in domestic cars, the use of this material has not disappeared in cars produced abroad. Dong Jianping, deputy secretary-general of the China Association of Automobile manufacturers, who has studied the domestic auto parts industry for many years, said that the reason why consumers were shocked to see asphalt damping sheets used in Mercedes-Benz, BMW and other models in reports is because they usually have little understanding of this industry. No understanding.
