Has your car been poisoned?

From March 1, the “Guidance on Air Quality Assessment for Passenger Vehicles” jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine has been officially implemented. Li Shufu and another NPC deputy also submitted relevant proposals on the control of the air quality of small cars in the “two sessions” this year. This shows that the problem of air pollution in the car has reached the point where it must be taken seriously.

Ordinary passenger car interior space is generally only 2-3 cubic meters, harmful gases such as toluene, benzene, xylene, formaldehyde and other volatile, combined with harmful gases such as carbon dioxide emitted by the human body, a long time in the dirty air, easily lead to Dizziness, headache, nausea. Scientific experiments show that with the increase of the ambient temperature and the decrease of the humidity, the molecular motion of benzene, formaldehyde, and volatile organic compounds will automatically accelerate and the pollutants will volatilize naturally faster than usual. Especially in summer hot weather, when the car is exposed to sunlight for more than one hour, the pollutants will exponentially increase. Therefore, experts in indoor environment reminded the majority of owners: In this kind of high-temperature place in Guangdong, we must be alert to the air pollution in the car.

The smell of new cars is a good smell of "compounds." The smell of some new cars is certainly pungent, but the smell of new cars radiated by most new cars is actually very mild. Some owners even think that the new car smells good. No matter how good smelling or pungent, the new car taste is definitely not a healthy smell, but the effect on the human body based on the different models is either large or small. For cars, paint, adhesives, and some plastic or synthetic parts of the car body are inherently harmful. In addition, the car's seat cushions, foot pads and some interior products are also releasing some invisible toxic gases, especially for heavily decorated vehicles. These harmful substances mainly include benzene, formaldehyde, acetone, xylene and so on. There is no doubt that the pollution in the car poses a threat to the human body. Every year, both domestically and abroad, there are cases in which the occupants are sick or even die due to pollution in the car. Women's inhalation reactions to benzene and formaldehyde are particularly sensitive. Especially in women during pregnancy, long-term inhalation of benzene can lead to fetal malformations and miscarriage.

Beware of the purchase of vehicles Although the country has not yet introduced a unified standard for the introduction of air pollution in cars, different manufacturers and models have different levels of pollution in the control of vehicles. Therefore, attention should be paid when selecting vehicles. Some consumers blindly value prices and appearance when choosing a car, and often ignore the pollution in the car.

Of course, due to the current lack of reference standards and no professional air testing equipment, the selection mainly relies on the sense of smell: the concentration of general harmful gases is directly proportional to the pungent degree of air in the car, and the general pungent harmful air must also exceed the standard. In addition, the eyes are also sensitive portable testers. Vehicles that cause serious eye discomfort are generally suspected of having excessive benzene. Therefore, picking a car that smells natural and does not irritate the eyes and skin is the first step to stop car pollution. Of course, if there are conditions, it is more accurate to be able to prepare a portable tester to test indoor formaldehyde concentration.

Car decoration should be rational in the eyes of domestic consumers, after a new car is bought back, flooring, plastic bags and other decorations almost become a must do homework. As everyone knows, these senseless decorations are worse than the poor air in the car.

The inferior adhesives used in floor-picking and the excessive amounts of additives that are contained in the low-grade leather are the culprits of accelerating the pollution of the cabin air. The vast majority of automotive perfumes, carpets and a large number of automotive interior decoration products on the market are all harmful gases. It is difficult to imagine how many bad car decorations are concentrated in small cars and how serious the air pollution will be. Therefore, when you are car decorating, you should consider the possible consequences.

Use Car Perfume Carefully Many owners like to put bottled perfume in their cars to improve indoor odors and rejuvenate themselves, but experts believe it is not desirable. Indoor environment experts believe that a good interior air standard must be non-toxic, harmless, and odor free. Many people often target no smell as a bad smell. In fact, excessive amounts of smell are odors. What is more serious is that most of the current perfumes are not natural extracts, but chemical synthetics, which themselves have some pollution. In the season when air conditioners are turned on in summer and winter, circulating pollution will be formed in the vehicle and the air quality will be damaged. The original pollution in the vehicle will intensify.

Always open windows to ventilate In most days of hot weather, especially in areas like Guangdong where summer and summer are the most part of the year, closing windows and opening air conditioners is almost the first must-do action for car owners. . Although the temperature inside the car can cool down quickly, it also becomes a stuffy tank with no air circulation due to the airtightness of the windows. The dirty air in the car is difficult to emit for a long time.

Therefore, experts suggest that we should use the air circulation inside and outside the car as much as possible to dissipate heat, one can save energy, and the other can use a large amount of fresh air outside the car to dilute the original toxic pollutants in the car. Even if the pollution in the car is serious at the time of delivery, as long as the car can be driven by the window, it can take up to two months to remove the odor from the car.

The term "actively attacking high-tech photocatalysts" is not unfamiliar to everyone. It is a kind of nano-titanium dioxide-based catalyst material. Under the irradiation of ultraviolet light, it has the ability of photo-oxidation and reduction, which can decompose and remove formaldehyde, benzene, SOx, NOx and other pollutants in the air, and can kill bacteria, viruses, fungi and plant pollen in the air, etc. . Compared with other conventional air purification methods, it has features such as simple equipment, strong purification ability, wide application range, long lasting stability, no secondary pollution, and low maintenance cost. Many photocatalyst processing technologies and equipments for vehicles have appeared on the market. Photocatalyst coating of the car can be sprayed on the special photocatalyst installation unit of the vehicle. Under the irradiation of sunlight, the function of purifying air and sterilizing can be obtained.

In addition, there is a formaldehyde scavenger similar to the fragrance seat that can use the unique gene reaction to efficiently capture the formaldehyde molecules in the air of the car and continue to function. This product can be used in all new formaldehyde-containing decorative materials such as new houses, carriages, etc. Formaldehyde is also the most toxic gas in the cabin air.

Moisture and mildew can also attract illness. The rainy season has not yet passed. The rain has left the cabin and air conditioning system with severe moisture. Over time, the car is filled with a mildew. If you turn on the air conditioner, then it would be even worse. The stench of sour smell and odor would be tempting to ask if the car had put spoiled milk on it? In fact, the generation of odors is due to the long-term retention of moisture in fabric components such as roofs, seats, and carpets, etc., and the moisture in the air-conditioning pipes cannot be dissipated for a long time. Over time, it will produce a rich acid odor, and even produce molds that are harmful to the body, causing headaches, fever, sudden sore throat, tonsil infections, asthma, flu symptoms, dermatitis, and difficult wound healing.

Air-conditioning refrigeration is known as dehumidification, we all know that air-conditioning can not only cooling, but also play a role in dehumidification. This is why people are urged to pay more attention to drinking water in the air-conditioned rooms or cars. Therefore, even if the temperature is not high in rainy weather conditions, the owner should consciously start air conditioning for a period of time before he reaches his destination, removing the accumulated moisture in the cabin.

Sunbathing Natural Sterilization In sunny days, holding the quilt to the sun on the balcony can effectively prevent mildew and odor, which may be the most original and most convenient and cheap disinfection method. In his own car, dark insulation films are placed on all four windows, and the cabin has almost no chance to enjoy the sun all year round. If it is the same as a quilt, on a nice day, take a break and shake the window glass to open the door. Let the cabins breathe and enjoy sunbathing. The mold naturally has no place to hide.

Photocatalyst is once again a very popular photocatalyst technology is also a good player to eliminate bacteria. Although there is no noticeable difference after the photocatalyst construction, this invisible protective film (titanium dioxide) can effectively eliminate many kinds of pathogenic bacteria after sun exposure, and it can also eliminate the odor inside the cabin. In addition, there is a sunscreen with photocatalyst technology to choose from, so that the sunshade and disinfection are correct.

If the carriages have already had obvious signs of mildew, it is imperative to conduct a thorough cleaning of the carriages. Of course, this kind of professional life is still recommended to a professional vehicle cleaning and beauty shop. Because cleaning filthy seats and interiors with stubborn stains is not an easy task, experienced car beauty shops will first use high-temperature steam jets to smash down velvet seats and interiors. First, in order to soften the deep stains for the next dry cleaning; Second, high-temperature steam can kill the velvet surface mold, play a role in deep disinfection.

After finishing the “sauna” for the interior, the beautician will apply a dry-cleaning foam cleaner on the surface of the velvet interior, and then use an electric scrubbing machine to dry-clean it.

After the brushing is completed, the beautician wipes the remaining cleanser with a dry rag. If it is still wet, the hair dryer will blow dry the velvet surface. After such a treatment, the velvet seat and the interior are renewed, restoring the color of the new car. The main thing is that the mold has been removed, the musty taste has disappeared, and the smell of cleansing agent is there.

Air-conditioning can be dismantled and disinfected and compartment disinfection is different, air-conditioning pipeline stains and mildew can not be directly cleaned, the air-conditioning system is too complicated to dismantle, is also not realistic. In fact, just like the now popular engine-free demolition cleaning, the air-conditioning system can also be disinfected and disinfected!

Nowadays, there is an air-conditioner pipe-free decontamination cleaning agent on the market that is easy to use. Just spray the air-conditioning cleaning agent from the air-conditioning inlet of the automobile air conditioner. After about 20 minutes, the dirty water and dirty liquid that are washed out can be discharged from the air-conditioner outlet of the automobile chassis, and the odor of the air-conditioning outlet is completely disappeared. Because it is difficult to determine if the new product has chemical attack on the evaporator inside the pipeline as well as the motor and other electronic parts, there are not many people who use it.

The more mature method is the steam sterilization method commonly used in car beauty shops. High-temperature steam of 130°C is poured into the air-conditioning pipeline, and all the bacteria hidden in the pipeline are killed with high temperature. In general, disinfecting air-conditioning pipes once a year is sufficient, and steam sterilization is still the most popular and effective method of disinfecting air-conditioning pipes. This method is simple and easy, and the water vapor will not cause any chemical corrosion inside the air conditioner. The bactericidal effect of the high-temperature steam is also quite satisfactory. After the operation, the odor in the air conditioner immediately disappears. However, people are worried about whether the high temperature of steam will lead to the deformation of the plastic parts in the air-conditioning pipeline. Therefore, the disinfection time and the steam temperature must be strictly controlled. In addition, since the steam itself does not have a bactericidal component, it cannot play a preventive role.
