I have bought the car for half a year, and I usually drive it. Why does the car always smell bad? Why does the car always give off a lot of pungent smell after high temperature exposure every summer? Is this a problem that has been bothering you for a long time, but can't be solved well? To find out this, you need to know the source of the smell inside the car. Let's do a simple science popularization to avoid some misunderstandings.
The sources of odor in the car are mainly divided into volatile organic compounds (VOC) released by interior materials, harmful gases (tail gas emission) entering the car from the outside, and articles (foot pads, cushions, etc. ) put it in the car. The odor emitted by inferior indoor decoration will not only affect our driving comfort, but also seriously affect human health and safety if VOC gases such as formaldehyde volatilize beyond the standard.
However, the smell is harmful. In order to meet the consumer's demand for beautiful and comfortable interior decoration, as well as the demand for energy saving and lightweight, car companies use a large number of non-metallic materials on interior trim panels.
Such as polypropylene, polyurethane, PVC, leather, rubber, fabric, etc. Due to the characteristics of their own materials and various additives and auxiliaries added in the production process, these interiors will continuously release some odorous volatile substances during the later use of the car by consumers, resulting in odor in the car. The smell is harmful and not rigorous. After a simple science popularization, let's take a look at how VV6 builds a healthy cockpit.
VV6 adopts low V0C and environmentally friendly materials, such as low-emission PU foam instrument panel, environmentally friendly white cotton and PU foam carpet, imported raw rubber sealing strip, EPP foam sun visor, NAPPA leather seat, water-based damping rubber plate painted with paint, etc.
Take the damping rubber plate as an example (applied to the silencing and damping parts in the car). I believe some riders also know that some models use asphalt rubber sheets, VV6 uses water-soluble damping rubber sheets, and the raw materials for seat foaming are food-grade silicone oil and so on. This sealant is also the first choice for low-odor green materials such as water-based rubber. These effective measures also reduce the volatilization of VOC.
Choosing environmentally friendly raw materials with low volatility and odor is only the first step, followed by targeted tests and experiments in the VOC environmental simulation laboratory of the whole vehicle. Under the temperature difference of 15℃ to 40℃ (simulated room temperature), the air tightness of the vehicle is ensured. Generally, after 16 hours, the temperature inside the car reaches above 60℃, and the air inside the car is sampled after the VOC is completely volatilized.
At this time, technicians will use professional instruments to analyze the VOC components in the air. If any substance exceeds the standard, they will make targeted adjustments, reduce the use or replacement of this covering, and conduct the next round of testing until the best results are achieved.
In fact, smell has both objective and subjective factors. The objective level (whether it is harmful or not) has been introduced above, so what about the subjective level (whether it smells good) VV6? What are the solutions? If it is harmless but pungent, I believe everyone can't accept it.
On VV6, automobile interior parts are classified according to small parts and middle parts, and the odor intensity, odor type and odor grade of air samples are recorded through strict sniffing by odor assessors. The rating adopts decimal 0.25, which is more accurate than the 0.5 specified in the national standard. The odor evaluator will also ensure that the odor grade acceptance of the whole vehicle, parts and materials is better than the national standard, and the taste acceptable to all people is the minimum standard.
VV6 is equipped with remote control function. In view of the poor air quality in the car after long-term exposure, the cabin cleaning function can be turned on remotely through the mobile phone APP, so that the air in the car can be externally circulated for ventilation and the turbid air can be discharged. When it enters the car, the air will become much clearer. VV6 is also equipped with CN95 automotive air filter and plasma air purifier, which is equivalent to bringing a N95 mask and an air purifier to the car. If frequent ventilation is too troublesome, you can also set the opening time independently and start the external circulation of the air conditioner regularly.
While the electric and intelligent automobile technology brings us convenience, the electromagnetic radiation emitted by the electronic components in the car will also cause harm to human health, and the harm caused by the unclear perception of electromagnetic radiation is also the most easily overlooked in our daily life. WEY brand owns the EMC laboratory of 10 meter vehicle pioneered by domestic automobile enterprises. In terms of personnel protection in the vehicle, under normal driving conditions, VV6 can monitor and quantitatively evaluate the electromagnetic radiation in key areas such as the driver's head, chest, limbs, etc., and optimize and adjust in time when finding abnormalities or exceeding the standard, so as to reduce the impact on human health.
For the vehicle level, EMC Lab can also carry out a number of test items such as vehicle radiation immunity, verify the electromagnetic compatibility of vehicles, and make targeted adjustments to ensure that the electromagnetic interference emitted by vehicles will not interfere with the surrounding environment, and at the same time ensure that vehicles have the ability to resist electromagnetic interference in the environment. A very intuitive example is that the communication in the car always fails, and the inexplicable crash of the vehicle system is related to electromagnetic interference. On VV6, the probability of these situations will be very low.
Give us a brief introduction of China automobile health index? Developed by China Automotive Engineering Research Institute Co., Ltd. under the guidance of International Traffic Medicine Association. The third-party evaluation system based on the trinity of automobile consumers, automobile enterprises and national policies is famous for its fair, open and true evaluation data and authoritative. And in the test, there are the most stringent requirements for the evaluation items such as volatile organic compounds (VOC), odor intensity (VOL) and electromagnetic radiation (EMR) in the car. At present, there are only a handful of car companies that can get high scores in China, and VV6 can get double five-star certification with high gold content.
The purpose of telling you this is that we don't wear colored glasses, which also means that these large OEMs have invested a lot of manpower and financial resources in controlling product quality, and some aspects are still very desirable.
Back to the original question, among the three conditions of how to choose a "healthy car", WEY? VV6 undoubtedly meets the first two points. As for the last point, in terms of purchasing power, VV6 has the inherent advantages of reasonable price, attractive appearance, large space and high configuration, and is extremely competitive. If you go to a 4S shop for a test drive, you will feel that it is in line with your preferences after the actual experience. In the price range of 1.5 million, 202 1? VV6 deserves to be included in your shopping list.
