& Factors in the use of inferior materials. The reason why luxury cars such as Mercedes-Benz, BMW and Audi use asphalt instead of environmentally friendly materials such as resin and rubber is because, on the one hand, there are currently no relevant national standards for auto parts and auxiliary materials in my country. On the other hand, , using asphalt can reduce the production cost of enterprises. Zhou Guangya, a senior engineer at the Materials Technology Institute of China National Heavy Duty Truck Technology Center, analyzed that taking an ordinary sedan as an example, the asphalt damping sheet inside the car would use about three square meters if it is two millimeters thick, and the price is about 1 to 1 yuan. With the use of environmentally friendly materials, the cost of each vehicle may increase by about RMB to RMB.
What is chilling is that Mercedes-Benz, BMW, and Audi, which have always been widely praised by consumers, just to reduce the cost of one or two hundred yuan, the manufacturers choose products that may cause serious pollution to the air in the car and endanger human health. Hazardous raw materials. There are tens of thousands of parts in a car, and low-quality materials are used in the small damping plates. Are there also other polluting materials? These three major companies should truthfully give a responsible account to millions of Chinese car owners.
Automotive damping sheet industry standards may be released soon
The Ministry of Industry and Information Technology issued an announcement on January 1, last year, saying that several industry standards, including automotive industry standards, have been approved. The automotive industry standards that will be implemented on January 1 this year include automotive damping sheet standards.
It is understood that this industry recommended standard "& Damping Film for Automobiles", which is mainly aimed at damping sheets made of asphalt material, stipulates the terms, definitions, product classifications, technical requirements, test methods, inspection rules, etc. of damping films for automobiles. , suitable for hot-melt, self-adhesive and magnetic damping films made of modified asphalt as the main material and used in different parts of the car body. This standard does not contemplate prohibiting the use of asphalt materials in the damping sheet industry.
A car has tens of thousands of parts. In addition to damping sheets, are other materials in the car polluted? How to detect and control toxic and hazardous substances in automobiles at the source? Under our country’s current standard system, we cannot conduct testing one by one. Because the most critical thing is that our country’s industry standards are not perfect. In addition, the majority of car companies do not pay enough attention to related issues and have insufficient self-discipline. In the United States, the Environmental Protection Agency requires that materials used in automobile manufacturing plants must be declared and must be reviewed by the environmental protection department to ensure that the hazards to the environment and human body are minimized before they can be used. Once the declarer violates the regulations, he will bear a huge fine and have to recall the product to clean up the pollution. The person responsible may even be sentenced.
