Attention must be paid to the problem of automobile formaldehyde

Update Date: 15:03, December 25, 2019 Views: 188
Over the years, the car has gradually become the travel tool purchased by every family, but the car also has potential safety risks. Do you know them? In recent years, with the further maturity of China's automobile consumer market, car owners' requirements for the quality of their cars are much higher than before. A month ago, we investigated the air quality of some cars in wufangtianyan. At the time, more than 50% of consumers made it clear that they didn't care. However, the majority of radio stations will solicit opinions on the formaldehyde content of automobiles in China. When it comes to the air quality of cars, many car owners think that there is no national standard in China. On March 1, 2012, China promulgated China's first automobile air quality standard - "guidelines for evaluating air quality inside passenger cars". However, it is not a mandatory regulation, but only an industry technical standard.

According to the current guidelines for air quality assessment in passenger cars, eight substances, such as benzene, formaldehyde, toluene, xylene, ethylbenzene, styrene, acetaldehyde and acrolein, were detected in the air of passenger cars. However, many insiders, including the rear curtain of the Chinese Academy of engineering, believe that there are hundreds of volatile organic compounds in the air inside the car. "Guidelines for the assessment of air quality in passenger cars" only stipulates the concentration limits of eight volatile organic compounds, so the coverage of pollutants needs to be expanded. However, many air testers now focus on formaldehyde and TVOC (various volatile organic compounds).
 
Do you have any misunderstanding about formaldehyde in cars? Misunderstanding 1: formaldehyde is present in new cars, but not in old ones. Many citizens think that after buying a new car, there will be some formaldehyde in the car. After a few years of driving, there will be no more formaldehyde. This is actually a mistake, and it has been proved in fact. It has been more than two years since the beginning of 2012. The formaldehyde content measured yesterday morning was still 0.11 mg / m3, still exceeding the national standard of 0.01 mg / m3.

High grade cars will not exceed the standard of formaldehyde
 
High grade cars, will you encounter the situation of excessive formaldehyde? In fact, this kind of material can also happen in the interior of high-grade cars A maintenance shop owner told Xiaobian that a luxury car worth more than 2 million yuan had been bought for about three years, but after two professional tests, it was found that the formaldehyde content in the car was still slightly higher. "After careful analysis, we found that the owner may have redecorated the car," the owner said, which is why the formaldehyde in the car exceeded the standard. It is understood that not only one high-end car was found to exceed the standard. "Not long ago, a car worth about 600000 yuan was tested. After buying this car for a year, there is always a pungent smell in it. At that time, after sampling and testing with professional equipment, it was found that the formaldehyde content in the car exceeded the standard. " However, if detected in the high temperature at noon, formaldehyde will be more serious. Misunderstanding 3
 
If the car has an odor, it must exceed the formaldehyde standard.
 
The car company just launched a new car, always feel that there is a strange smell in the car, so must formaldehyde exceed the standard? The smell in the car is not necessarily formaldehyde, but also other harmful substances, such as plasticizers. "This odor is not to be ignored, and it can also affect human health after entering the human body."
 
Car odor and other issues can not be ignored. About car owners choose chemicals such as air fresheners to mask the smell. In fact, these products can not fundamentally solve this problem, "long-term intake of artificial flavor additives may also lead to the intake of more chemicals."
