In recent years, complaints about air pollution in vehicles have never stopped. In 2011, the “GB/T 27630-2011 Passenger Car Air Quality Assessment Guide” issued by the state put forward restrictions on VOC concentration in the car, but for automotive products. There is a lack of effective control over all aspects of manufacturing, and this situation is expected to change!

The weather is cold, and the closed car environment makes the air pollution problem in the car stand out again. If you freeze the window, as some children's shoes joked: "That is the smog." The outside of the car is smog. The car is volatilized from interior parts such as plastic, leather, fabric, and glue. In-vehicle air pollution caused by organic compounds (VOC). Why is it so difficult when the car is on the road and let us enjoy a clean breathing environment?

In 1955, Americans detected more than 100 volatile organic compounds in the air, among which benzene, toluene, ethylbenzene, xylene and styrene were carcinogenic and teratogenic; formaldehyde, acetaldehyde and acrolein were carcinogenic. effect. In recent years, domestic consumers’ complaints about air pollution in vehicles have never stopped. Song Guangsheng, director of the National Indoor Environmental Quality Inspection Center, once said: "The cars running on the road, 80% of the cars have air pollution problems, especially those who are exceeding the standard are the two brothers of toluene and xylene." Today, the problem of air pollution inside the car Still exist. On November 5, 2015, the Voice of the Central People's Broadcasting Station, "Daily 315", exposed the problem of air pollution inside the luxury car.

There are children's shoes that may jump out and say: "I have a car air purifier in my car that can block VOC," or "You look at the activated carbon bag that adsorbs VOC in a row after my car." But in fact many car air purifiers All are floating clouds, and the activated carbon package is not reliable!

Take the car purifier of a well-known brand (name is not convenient, everyone knows), for example, in Tmall is also the corner of the sales champion level. Its car price evolution is 499 yuan, a car air evolution, on the principle of purification: HEPA filter. HEPA (High Efficiency particulate air filter), Chinese means high-efficiency air filter, HEPA-compliant filter, effective rate of 99.7% for 0.1 micron and 0.3 micron, but this filter only works for PM2.5. That is, only fine particles can be filtered out, and there is often no power for molecular-level VOC substances.

Another car air evolution device with a promotional price of 799 yuan, in addition to the HEPA filter on the purification principle, also added activated carbon. Activated carbon can indeed adsorb VOC substances, but the adsorption capacity of activated carbon for VOC substances is limited, and when the temperature reaches a certain height, the activated carbon will "spit" the adsorbed VOC substances to form secondary pollution.

How is the problem of air pollution inside the car broken? It is necessary to strengthen the effective control of all aspects of product manufacturing.

On January 21-22, 2016, China Automotive Technology and Research Center organized a working conference on the research of VOC control and management system for volatile hazardous substances in automobiles in Haikou. The members of each research group prepared the volatility in the car. The Hazardous Substance Control Management Requirements (Draft) (hereinafter referred to as the “Management Requirements”) was discussed. The "Management Requirements" clearly establishes a list of high-risk parts and a list of low-VOC materials to further implement the green supply chain management system for automotive products; establish a consumer-oriented information disclosure system, that is, the "VOC Information Publicity Platform" is released in the authority car. VOC information, urge enterprises to increase VOC control.

In addition, one of the members of the research team, Kumho Rili shared the VOC control technology in the material production process. The products of Kumho Riley are more than 60% lower than the traditional interior plastics, far lower than the VOC emission standards of major OEMs, and truly control the air pollution inside the car from the source.

It is not a dream to control the air pollution inside the car. The degree of control over the manufacturing process of automobile products has also been put on the agenda. I believe that in the near future, we will be able to enjoy a clean breathing environment inside the car. Even if the fog outside the car is raging, we just have to "hid in the car to become a unified system, and manage him in spring, summer and autumn and winter!"
