When midsummer comes, everyone has one feeling: hot! Hot! Hot! Hot! Many people don't know that at this time, the problem of volatiles in the car will become a "health killer" that everyone can't see.
In the case of high temperatures, some cars become "gas chambers" where VOC emissions from interior materials, while others can maintain the standard of a green cockpit. Not long ago, Dongfeng Peugeot's new 408 model, which has obtained the children's priority green cockpit certification, challenged the high temperature in the Flaming Mountain of Xinjiang.
The Huoshan Mountains in Xinjiang are in a state of high heat all year round, and the solar radiation is extremely strong. Dongfeng Peugeot's new 408 model is tested in such a harsh high-temperature environment in order to simulate the extreme environment of everyone's various cars.
As time went on, the sun gradually increased, and the temperature of the Flaming Mountain also climbed sharply, soon exceeding 40°C, and the heat wave on the ground was rolling.
However, the situation inside the car surprised everyone slightly. Despite the unbearable heat outside, the temperature inside the car rises relatively slowly. This is a visual indication of the excellent thermal insulation design of the new 408 and the use of high-quality interior materials.
As the temperature rises further, the air conditioning system in the car is also working hard, in the air conditioning cooling test, the air temperature in the car cabin reached 75 °C, in such an extreme high temperature environment, the new 408 Lang Lang model car air conditioning starts normally, the air conditioning refrigeration is normal, the temperature drops to 24.8 °C soon when the air conditioning is turned on in the engine idle mode, and the air conditioning is turned on for about 5 minutes, and the body feels cool.
In this high-temperature "baking inspection" process, the people present paid close attention to every detail of the vehicle. They carefully inspect the paint for fading and blistering. Whether there are signs of deformation and aging of various sealing strips, and whether there is any peculiar smell from plastic parts and leather in the car.
Happily, the new 408 excels in these areas, with the paint remaining bright and colourful, without any blistering or softening, and the bodywork and door seals fit snugly.
In high-temperature in-vehicle environment testing, odor and volatile organic compounds are the two dimensions of cabin air quality control. Some substances, such as xylene, are usually found in solvent glues, and long-term exposure can cause neurasthenia; And some substances, the smell is not obvious, but long-term inhalation, will stimulate the senses, thus causing headaches, such as aldehydes, usually found in leather and recycled materials, the average consumer is difficult to intuitively understand, it depends on the conscience of the car manufacturer.
In the high-temperature test, the performance of the new Dongfeng Peugeot 408 model does not seem to be greatly affected. The electronics in the car are operating normally, and we can see that the various dashboard data shows that everything is normal.
Here is a national standard for popular science. In the "Guidelines for the Evaluation of Air Quality in Passenger Cars" (GB/T 27630-2011), it is required that the formaldehyde concentration in the car shall not be higher than 0.10mg/m3. In this high-temperature test, the formaldehyde number of the new 408 model is only 0.005mg/m3 at a high temperature of 75°C in the car. The results are directly better than the national standard.
In the face of more stringent standards, such as the second draft of the "Guidelines for the Evaluation of Air Quality in Passenger Cars", which recommends that the TVOC in the car be less than 8mg/m3, in this high-temperature test, the TVOC measured by the new 408 model is 2.1 mg/m3. It's really too low! It shows that the vehicle maintains a high-quality environment in the car even at high temperatures.
Dongfeng Peugeot's new 408 model has successfully withstood the brutal high temperature test of the Flaming Mountain. Resilience in extreme environments, and behind these results is the conscience of the car factory.
The new 408 model solves the problem of volatiles in the interior from the source, and in the manufacturing process, there is no use of waste fibers in traditional cars, and 11 kinds of soundproof parts used in the car are made of green materials.
Not only that, but the new 408 model also uses a large number of skin-friendly leather materials with low odor and low VOC characteristics. Even in the use of glue, we give priority to the use of environmentally friendly water-based glue and hot-melt adhesive, control and reduce the use of solvent-based glue, and try to use carding, welding and other processes in the connection of parts to reduce the bonding process and eliminate the pollution of harmful substances from the source. Therefore, in the CEERI Children's Priority (Green Cockpit) certification, it has become the first entry-level family sedan to pass the "Children's Priority Green Cockpit".
Now, DPCA's "618 Heartbeat Shopping Season" is in full swing, and it is understood that during this period, the purchase of Dongfeng Peugeot's new 408 model terminal discount starts at 79,700. After watching the exposure to high temperature test in the Flame Mountain, you who pay special attention to the environmental protection and health in the car, can you hurry up?
This exposure test not only allows people to have a deeper understanding of the new Dongfeng Peugeot 408 model, but also illustrates a problem, as long as it really uses good materials and good craftsmanship to manufacture a conscientious car, it will be able to bloom its own light in the automotive world.
