Rubber automotive damping sheet extruder

Introduction to Rubber Car Damping Sheet Extruder Damping sheet is a viscoelastic material attached to the inner surface of the car body. It is close to the steel plate wall of the car body. It is mainly used to reduce noise and vibration, that is to say, it plays a role in reducing noise and vibration. to the damping effect. Damping sheets are installed in all cars, such as Mercedes-Benz, BMW and other brand cars. In addition, damping sheets are also used in aerospace vehicles, aircraft and other machinery that require vibration and noise reduction.
Recently, damping sheets have become a hot word recently, but many people may not know what a damping sheet is. To this end, Beijing Business Daily reporters specially interviewed a number of industry experts to interpret this term for readers.
The damping sheet is a material attached to the inner surface of the car body, close to the steel plate wall of the car body, mainly to reduce noise and vibration. Damping plates are installed in all cars. In addition, damping sheets are also used in aerospace vehicles, aircraft and other machinery that require vibration and noise reduction.
Previously, CCTV reported that asphalt damping sheets are used in China. Such damping sheets can cause air pollution in cars and endanger human health. Taking a car as an example, there are many places where such damping sheets need to be attached, most of which are located in a closed car cab, with a total area of about square meters, and the total amount of asphalt used is about kilograms.
However, according to media reports, an unnamed person from FAW-Volkswagen Audi said that FAW-Volkswagen and Audi have simultaneously implemented regulations on modified petroleum asphalt damping sheets produced in China and Germany used in Audi vehicles, as well as on complete vehicles. The indoor air quality was tested again, and the results showed that formaldehyde, haze, and total carbon were all qualified, and the emissions did not contain benzopyrene and other polycyclic aromatic hydrocarbon carcinogens. The test results show that the gas emissions in domestically produced Audi vehicles fully comply with Audi's global standards and meet EU standards. Of course, they also meet the standards of the "Passenger Car Interior Air Quality Evaluation Guidelines" promulgated by China.
As for the damping sheet issue raised by CCTV, the above-mentioned person said that Audi's damping sheet uses modified asphalt, which is the same in all Audi cars around the world, and there is no problem.
