Attack expose one's past misdeeds innocently, this article is only " be practical and realistic " invite customer more be at ease buy a car, hope at the same time car media, every involves the problem story of bottom line of life, morality, want a heart to put to the fact awe-stricken.
Yesterday, some famous car media publishs home first " get a gram the air inside 03 cars detects the result gives furnace TVOC carcinogenic substance to exceed nearly 3 times " article, caused Hua Xiaomei's attention.
Look suddenly, "Get a gram 03 " , " TVOC " , " carcinogenic substance " wait for a word all the more dazzling.
And see this article, unidentified whether did the consumer that manages also frighten jump: Get a gram carcinogenic substance of TVOC of 03 this cars exceeds bid nearly 3 times, did not have conscience really.
Everybody knows, ao Di " mephitis door " in sending cancerous incident to fermenting.
This is this article probably those who publish " big setting " : It is Ao Di not only abhorrent, the car that get a gram also lacked great mind, TVOC carcinogenic substance exceeds bid nearly 3 times, who is bought want whose lot.
Can is the truth such?
Be necessary the knowledge below popular science: TVOC is not equal to carcinogenic substance, TVOC exceeds bid also with send cancer to do not have immediate impact.
This involves the understanding to TVOC: It is Volatile (volatile) , Organic (organic) , Compound (compound) 3 words abbreviate of the first abecedarian, and all sorts of VOC that are measured always are called TVOC of total volatile organic matter -- the organic compound in air.
Told in vain continuously, the air inside the vehicle that is measured namely contains all sorts of organic, compound wait for material volatilize, for example paint, glue volatilize, but measuring an outcome also is to be able to suffer exterior element interference.
For example, sweet atmosphere was used inside the car, suffer tail gas to discharge, girl gush perfume, smelly even foot haze of flavour, mist can cause TVOC to exceed bid.
Will tell commonly, the main source of TVOC is outdoor, basically come from fuel combustion and traffic carry: And basically come from coal fired and the aerosol that wait for products of combustion, smoking, heating and cook indoors, build and decorate material, furniture, electric home appliances TVOC has nearly 1000 to plant, and its form very complex also, also cannot measure alone normally. Divide in all commonly it is 8 kinds: Alkyl kind, aromatic hydrocarbon kind, Xi kind, bittern hydrocarbon kind, ester kind, aldehyde kind, ketone and other. And indoor standard regulation, TVOC every stere must not exceed 0.6 milligram, that is to say these 8 kinds no matter who volatilizes, cannot exceed this upper limit. But, quality of the air inside the car is 8 fractionation of TVOC styrene, ethylbenzene, aldehyde, acrolein 4, because,also be: Great majority model cannot cross what indoor empty temperament measures to close on TVOC test, multiply the ability that use a car to be able to lower a threshold so. Here has a key: Great majority model cannot cross what indoor empty temperament measures to close on TVOC test, and the more luxurious car often TVOC concentration is higher, pledge because of the material such as used organic compound, leather, colloid, glue cheaper the car is much. For example, the TVOC content that an old nimble amounts to, should grind on larger possibility press to run quickly brand-newly S class car. (later development explains a reason) Of course, TVOC chroma nature is lower better, but chroma exceeds mark to be not represented not environmental protection, cannot understand one-sidedly more to have poisonous and carcinogenic substance, harmful etc. And, because TVOC is had strong volatile, need a window only so ventilated, very the TVOC inside express can amount to mark, namely everybody often says -- tasted without new car. To this, professional personage also expressed his view to Hua Xiaomei: "Flavour pilot is good, be no problem certainly; Sapid do not be equal to insecure. Sapid do not be equal to insecure.. Say so, TVOC carcinogenic substance exceeds bid, that should look really specific the what that what material volatilizes character be. Think commonly, when TVOC chroma is 3.0-25 Mg/ M3, meeting generation is stimulated and unwell, with other factor combined action when, the likelihood appears have a headache; is more than 25 Mg/ M3 when VOC chroma when, divide outside having a headache, the likelihood appears other nerve noxiousness action. And this some famous car media overcomes the 03 TVOC tests that have to getting, the indoor air quality that uses more severe exacting is measured, what is the outcome that then it measures? TVOC measures an outcome is: Get a gram content of the TVOC inside 03 cars is 1.76mg/ M3, exceed bid mark of indoor air check is nearly 3 times more accurate, but do not have disclosing after all is to detect gave the sort of carcinogenic substance to exceed bid. And the numerical value of 1.76mg/ M3 is far also the chroma under meeting generation stimulation and unwell 3.0-25 Mg/ M3. So, get a gram content of the TVOC inside 03 cars is 1.76 Mg/ M3 (the new car that does not exceed 2 months) , chroma exceeds bid nearly 3 times, this numerical value and other car photograph are compared, can you lie what level? Above data makes clear: Get a gram the TVOC numerical value of 03 lies the standard of luxurious car. Everybody sees, ES300h, Martha pulls Leikesasi Model S of Levante of the base of a fruit, tesla, contemporary road is gotten the better of, Biyadi the Tang Dynasty wait for TVOC numerical value to exceed multiple, and masses golf 7 all previous still exceed bid via chroma of 32 months TVOC. So ask a reader to think, above these cars (have car of 1 million a person of extraordinary powers even) if say according to above paragraphs place, TVOC carcinogenic substance already exceeded bid multiple, so are they true " poisonous and harmful " ? Apparent, "TVOC carcinogenic substance " it is inaccurate view. So authoritative view, be how unscramble? Domestic famous car from media " east pull on the west car " point out in a report: Current, to the sky inside the car temperament measures the most authoritative research, come from) of center of zoology of Ecology Center(of orgnaization of a blame gain of American, this orgnaization pays close attention to quality of the air inside the car for years continuously, had published to enrage the research achievement of chemical material content about the sky inside the car 2012, this one achievement is cited extensively by global media and academic orgnaization. The expert of Ecology Center points out, che Yuexin, quality of the airy inside the car is poorer, flavour of so called new car, it is the chemical component in the material inside the car not stable still, very easy command gives out what after coming, form. "New car flavour " in basically coming from material of car interior trim, send out the VOC that come out (volatile organic compound) , and a variety of component blended in VOC, have everybody among them familiar to the ear can the formaldehyde of detailed, aldehyde, benzene, toluene, xylene " toxin " . And occupy research proof additionally: The more luxurious car TVOC exceeds bid the likelihood is more serious, because all sorts of organic soft adornment are much, and these soft outfit are to need binder ability to wrap Fu to be on base material. Binder is one of main contribution sources of the VOC inside the car. This also is why can say, chroma of luxurious car TVOC wants outclass general have transport service commonly. Manage together, because get,overcoming 03 interior trim luxurious, accuse in, use plaque of seat, door soft qualitative, coriaceous wait for material to lap character, these natural need use a large number of binder, can exceed bid with respect to TVOC of hard to avoid in new car phase so, but exceed mark to be not " poisonous and harmful " . Everybody familiar to the ear can the formaldehyde of detailed, aldehyde, benzene, toluene, xylene these " toxin " whether amounting to mark just is crucial. But measure a result to show according to some famous car media, get a gram this 03 cars not only each easy carcinogen is far under national level, more luxurious than the part even car wants environmental protection. What does such data make clear? Get a gram the interior trim that 03 have more luxurious than the shoulder car not only, and also be an environmental protection and extremely healthy car, so consumer can be at ease completely choose and buy. But, after buying new car, exceed the label effect to human body to prevent TVOC concentration, need to remember keeping ventilated only can. And think commonly, chroma of new car TVOC is in half an year or it is normal inside a year to acute is decreased or will tend somewhat standard. Unless this car detects,go out contain exceed bid radiative content, easy carcinogenic substance, usually, TVOC chroma exceeds bid (short-term control is in 2, 4 times less than) won't cause to human body cause the harm such as cancer. Needing special specification is: Hua Xiaomei the assessment that makes to above, can be to build completely in approbate and agree with media of domestic famous car completely to be in " get a gram the air inside 03 cars detects the result gives furnace TVOC carcinogenic substance to exceed nearly 3 times " announce in one article detect over result foundation. Because, consumer needs to understand the fact of TVOC, after all car " carcinogenic substance " wait for a report, it is very fearsome, very serious also problem.
