Have you noticed that after a period of exposure in the hot summer, the car came to a head when it opened the door, which was particularly annoying. Most of them are volatile and harmful substances after high temperature reaction, which is probably the initiator of "hematologic cancer"-formaldehyde. To deal with formaldehyde, we should be prepared for a protracted war.
First of all, you have to confirm whether the formaldehyde in your car exceeds the standard. Don't tell me that the formaldehyde detectors in online celebrities, hundreds of thousands online, are all used to harvest IQ tax. Both China Interior Decoration Association and Material Center of Surveying and Mapping Institute have made it clear that the values measured by this air detection instrument with sensors as the core components are extremely unstable, and the error rate is quite large, and some products do not even indicate the error rate.

To this end, the professor suggests that you seek professional institutions with higher qualifications and reasonable fees for testing, and all of them use professional testing instruments of tens of thousands of yuan. Don't let the fake and shoddy detectors that fool people online delay the safety of passengers. It should be pointed out that the formaldehyde release cycle is generally 3- 15 years. Finding an unreliable team to deal with it may only reduce the formaldehyde content in a short time. It is suggested that professional things should be handed over to professional people.
Is there any trouble? Then kill the hidden danger from the source! Buy a "nontoxic and tasteless" safety car in one step! Then the question comes, how to measure whether a car is environmentally safe? You can't smell it with your nose, can you?

China Automobile Research Institute came out. It adheres to the position of objective neutrality, professional impartiality, open information and comprehensive evaluation. According to the principles of large market sales, high social concern and large number of complaints, it selects cars from the perspective of a third party, simulates the scene of consumers buying and using cars, and tests and evaluates the target vehicles.
The organization evaluates the "health index" of the tested vehicle by detecting volatile organic compounds (VOC), odor intensity (VOI) and electromagnetic radiation (EMR) in the vehicle, and also pays attention to the study of particulate matter (PM2.5) and in-vehicle sensitization evaluation (VAR) as observation items.
What do these crude proper nouns mean? Let's recall these fragments of life: when we were students, when we used correction fluid to alter things, when we used 502 resin glue to paste things, and when we tore open a large roll of transparent glue to wrap the express delivery, do you still remember the pungent smell that hit our faces? What's more, it will make eyes and throat feel uncomfortable, and volatile organic compounds (VOC) are the initiator.
Studies have shown that when the concentration of VOC in the environment reaches a certain level, it will make people feel headache, nausea, vomiting, fatigue, and even cause convulsions and coma, causing harm to the liver, kidneys, brain and nervous system, and causing serious consequences such as memory loss. Among them, formaldehyde and benzene are identified as carcinogenic risks, and benzene can also damage the hematopoietic system and induce leukemia, which is an out-and-out invisible killer.
Therefore, China Automobile Research Institute used various analytical methods to sample and analyze the air inside the car, and found that there were hundreds of chemical substances in the air, and the volatile organic compounds that caused the odor inside the car mainly included aldehydes, ketones, alkanes, esters, aromatic hydrocarbons and alcohols. When the VOI in the car exceeds the standard, "disease" will come to you sooner or later.
The data show that even if the VOI concentration in the car is reduced by 90%, people's sense of smell is only reduced by 50%. In other words, automobile manufacturers must greatly reduce the chemical concentration of VOI in the car to obviously improve the smell inside the car. Moreover, the materials in the cabin are complex and the space is narrow, and there are countless substances that can produce odor, and there are complex mechanisms between them. When the smell stimulates the human body to a certain extent, it will cause direct harm to the human body.
20 19, 19 On February 20th, China Automobile Health Index Management Center released the recommended models of China Automobile Health Index 20 19. The professor selected one of the more representative eco-cars for a simple evaluation. Don't miss it if you pay attention to safety and health.
SAIC-GM Cadillac? XT4？
Guide price: 259,700 yuan-396,5438 yuan+7,000 yuan.
It can be found from the above table that the average control level of formaldehyde in this batch of evaluation vehicles is not ideal, and the formaldehyde concentration rate in the vehicle measured at room temperature is high. It is not difficult to find that the health hazard index of formaldehyde at room temperature is the biggest deduction point for VOC plates, and the excellent and good rate of 20 test models is less than 50%. It can be seen that it is not easy to get high marks in the authoritative test of China Automotive Research Institute, and there is really little "participation" in brushing your face.
However, we can't generalize. The formaldehyde control of Cadillac XT4 in this list will ensure that the formaldehyde content in the car will not exceed the national standard limit of formaldehyde control at room temperature even under high temperature and strong light irradiation. You know, after the car is exposed to the sun for a long time, the formaldehyde content in the car will increase exponentially, and even the car can be turned into a small "gas chamber". Under harsh conditions, Cadillac XT4 can also inhibit the formaldehyde content, which is not easy.
Cadillac directly integrates odor control into the product design and development process, selects environmentally-friendly materials that meet the specifications, controls odor pollution from the source, and even establishes a professional team of odor assessors to control the odor of interior materials and the whole vehicle. Finally, I got a quasi-five-star rating with a high score of 89.5, which is the best reward for the team's efforts.
On the other hand, the competing Volvo XC60, which has always been famous for its safety and environmental protection, was thrown out by Cadillac XT4 in the electromagnetic radiation board of vehicles 13.6 points, which was high and low, so it was hardly a true multi-directional environmental protection. I hope the factory will be improved later.
In order to reduce manufacturing costs, some car companies do not hesitate to choose inferior materials in places that consumers can't see. These "black-hearted materials" will release harmful substances continuously and slowly, which is often the "reason" that the smell of new cars cannot dissipate for a long time. But there are also people-oriented conscience models that refuse to do such dirty things, and Cadillac XT4 is one of them. In places where users can't see or touch seat fillers, sound insulation materials, rubber strip, adhesives, etc. Cadillac XT4 still uses high standards of environmentally friendly materials to keep formaldehyde out.
Don't think that electromagnetic radiation is exclusive to electric vehicles, and traditional fuel vehicles also have radiation problems. A large number of electrical components, electronic equipment and densely distributed wires of vehicles are the "culprits", and it is a long project to achieve better control. Even so, Cadillac CT4 got a five-star rating of 96.4 points in vehicle electromagnetic radiation (EMR), ranking among the best in this test list. From this point of view, Cadillac XT4, which has made gratifying achievements in vehicle volatile organic compounds, odor intensity and electromagnetic radiation, is indeed a competent pioneer in environmental protection.
As you can see, the interior of Cadillac XT4 window has a clean look and feel, the feeling of sunshine is transparent, and the exquisite interpretation of the cut-seam French double-needle edging technology makes you easily capture the hearts of China consumers as soon as you get on the bus. Looking at the market, the compact luxury SUV market has only begun to cluster in the past two years. BMW X 1, Cadillac XT4, Lexus UX, Volvo XC40, Jaguar E-PACE, etc., including Mercedes-Benz GLA and Audi Q3, are comparable to medium-sized SUVs in practicality, space performance and comprehensive strength. It is estimated that there are also BMW X 1 and Cadillac XT4.
But the thought of BMW X 1 adopting 1.5T three-cylinder engine makes people nervous. 140Ps horsepower approaching 1.6t weight big guy, 100km/hour 1 1 second, it seems that it doesn't match the landing price of more than 300,000 yuan. On the other hand, the whole system comes standard with 24 1Ps? Cadillac XT4 is equipped with a 2.0T engine, and combined with preferential entry-level models, the landing price is only 250,000, and the cost performance is high or low. This can be seen from the fact that Cadillac XT4 cut off nearly 50,000 sales in less than a year.
Beiqi New Energy? EU5？
Guide price: 132900 yuan-17 19000 yuan.
Driven by the policy, more and more new energy vehicles have entered the public's field of vision, and the attitude of domestic consumers towards electric vehicles has gradually changed from "resistance" to "willingness to understand". In addition to paying attention to the cruising range, charging time, spontaneous combustion and other issues of electric vehicles, users are also skeptical about their radiation. It is rumored that the radiation of electric vehicles will induce hair loss and cause cancer. Is that really the case?
No, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no, no.
But radiation is always harmful to health, of course, the less the better. As we all know, there will be electromagnetic radiation when there is a motor, and electromagnetic waves will be generated during electromagnetic conversion when the motor is running. If the shell is not sealed properly, electromagnetic waves will leak out and form electromagnetic radiation. Being in a closed environment with excessive radiation for a long time will do harm to the circulatory system, immunity, reproduction and metabolic functions of the human body, even induce cancer and accelerate the proliferation of cancer cells in the human body.
Aware of the problem, BAIC EU5 is specially equipped with a closed metal shell for the battery pack and motor, which can not only effectively prevent electromagnetic wave leakage and reduce radiation, but also isolate external radiation from entering the parts, causing work disorder. No wonder BAIC EU5, a new energy source? R500 can get a five-star praise of 89.7 points in vehicle electromagnetic radiation detection, which is commendable.
Back to products, Contemporary Ampere Technology Co., Ltd., the "number one player" of power battery supplier, provides battery packs for BAIC new energy EU5. According to the different battery capacity of vehicles, the new energy EU5 of BAIC is divided into three series models: R500, R550 and R600. The cruising range corresponds to 4 16km, 460km and 50 1km respectively, which can easily cope with daily commuting tasks, and it is not a big problem to charge for one week.
With the support of permanent magnet synchronous drive motor with maximum power 160kW and peak torque of 300n·m, the acceleration time of vehicles from 0 to 100 km/h is only 7.8s ... BAIC EU series is favored by online car sharing platforms because of its good space practicability and user reputation, and it has won 201/kloc-0 with outstanding achievements.
Closer to home, we can find that the EMR evaluation results of pure electric vehicles in this election have reached the five-star level, which shows that as long as the design and materials are proper, the electromagnetic radiation of pure electric vehicles is not necessarily higher or even better than that of fuel vehicles. Needless to say, those "electric blacks" and "new energy sprays" are harmful to health!
From this to that, the assertion that "a fuel car must be better than a fuel car" is believed to be broken sooner or later, and time will prove everything.
Ruifeng? S3？
Guide price: 67,900 yuan-87,900 yuan.
Ruifeng S3 can be regarded as an early group of veteran players who fought in the domestic small SUV market, and gained a certain mass base with good cost performance. However, with the wave after wave of new players marching into the battlefield, the competition in the independent small SUV market tends to be fierce, and the popularity and discourse power of Ruifeng S3 have long been worse than before.
Therefore, in July last year, Ruifeng S3 completed a complete replacement. In addition to a more refined and modern appearance and interior, the new car is also optimized at the level of "sniffing" experience. What did you say?/Sorry? The list above speaks for itself.
In the health index test of China Automobile Research Institute, Ruifeng S3 not only scored 88 points and four stars in the test of volatile organic compounds (VOC) and odor intensity (VOI) in the car, but also stood out in the test of electromagnetic radiation (EMR) in the car with 65,438+0,000.
In the 60,000-yuan small SUV market, potential users often only pay attention to the surface requirements such as the price, appearance and space of the vehicle when choosing such products. Even so, Ruifeng S3 has not reduced the cost in places where users are hard to detect, and has achieved the level of the first echelon in the same level in terms of volatile organic compounds, odor intensity and electromagnetic radiation of vehicles.
When people buy a car, they often fall into the strange circle of "buying a car by looking at the brand" and "choosing a car by looking at the sales volume", and often draw conclusions about the product strength of a car by its brand, price and positioning. How many products are there besides Jinyu during this period? How many good cars have been buried by public opinion? In the final analysis, the consumption pattern of domestic car buyers is not mature enough.
Fortunately, under the background of promoting supply-side structural reform, more and more third-party testing institutions provide reference opinions for domestic consumers when buying cars by establishing an intuitive, reliable and accurate evaluation system. Their appearance provides input for vehicle companies to optimize product configuration design, and also provides standards for the supervision of relevant departments, which promotes the comprehensive transformation of the independent automobile industry and leads the healthy development of the industry. I hope to see more and more "China Automobile Research Institute" emerge.
