"Freely formaldehyde room " incident ferments continuously, the detector does not rely on chart pr

"Freely formaldehyde room " incident ferments continuously, a lot of people begin to fear same existence formaldehyde exceeds mark issue in him home, buy formaldehyde to measure the formaldehyde such as detector of box, formaldehyde to detect oneself to the net in succession then product. However, the expert points out, the relevant product great majority on market did not obtain attestation aptitude, the result is suspect. And suffer fully chase after the activated carbon bag that hold in both hands, smooth accelerant to wait except formaldehyde method, also be pointed out action is limited, processing formaldehyde still needs from fountainhead proceed with.

After using up piping outfitting to repair designed " air " 3 months, but Xiaoxu still is not at ease. Open a net to buy platform, input " formaldehyde detects " , multifarious product makes Xiaoxu straight breathe out " big horizon " , "Cheap want a few only, expensive can go up 1000, already reagent of have the aid of surveys a case oneself than what get stuck to color, also have what can measure formaldehyde, PM2.5 at the same time is muti_function air detector. Also have what can measure formaldehyde, PM2.5 at the same time is muti_function air detector..

Recommend in the colleague below, xiaoxu buys finally " 6 syncretic " detector. According to service instruction, small Xuzai room is airtight the detector is opened after 12 hours, discover the numerical value on screen is not stable, "Low when indication formaldehyde is 0.036, tall when have 0.141 unexpectedly, that can exceed bid. That can exceed bid..

Small Xu You borrows the work in the same placing's detector to affirm again, "Cannot think of, two detectors that are the same as a paragraph are placed in a place side by side, measure the numerical value that come out to go unexpectedly very far, and not only it is formaldehyde, connect other index different also. Connect other index different also..

The far more than small Xu Yi's person that produces doubt to the detector. Considering oneself unit office building is decorated before long, feeling of corridor, office has a bit peculiar smell, xiaobai spent more than 300 yuan of nets technically to buy detector of a formaldehyde, plan belt was done in the past detect.

After the product arrives, little white convenient and easy to use opens an instrument, "Had not wanted to want to survey the home actually in, what because this is,buy 5 years ago is secondhand room, former at that time house-owner has lived 6 years, we do not have redo any decorating, bed, chest, mensal, sofa also is before move with the furniture that passes 56 years, feel to should not have a problem. " however, "Conveniently " detected result makes Xiaobai astonied: The formaldehyde content of every stere in the home achieved 0.236 milligram unexpectedly, be national level double much! Contrary, the result that Xiaobai detects in the unit with the detector does not exceed bid however, "If we lived this kind more than 10 years the house exceeds bid, that I but dare not believe new office building can amount to mark, just did not measure probably come out. Just did not measure probably come out..

Before moving formally, lin Xu has been done sufficient preparation, "Furniture reachs the designated position, I bought activated carbon of one big case to wrap, fully 40 bags, on corner, desk, the head of a bed puts have, should be enclothe in the round. " before next sheet, lin Xu still undertook one time comparative to congener product, "Activated carbon divides a lot of kinds, have mineralization activated carbon by raw material, also have coconut shell activated carbon, include globose activated carbon and grain activated carbon again by appearance. Include globose activated carbon and grain activated carbon again by appearance..

Look in Lin Xu, green plant is requisite likewise, "Like green trailing plants, bracketplant this is planted, it is allegedly ' suck formaldehyde ' ace, more than 10 are placed in house, should also can produce effect! " in addition, lin Xu still listens come many " folk prescription " , "Have say to use grapefruit skin, those who use tea, still have say to use vinegar or of onion, also put a drop, it is kind of psychology to comfort. It is kind of psychology to comfort..

Nevertheless, two months go, lin Xu is dissatisfactory to removing the effect of formaldehyde, "Enter room, still feel the eye is a bit uncomfortable, time grew voice a bit afflictive also, the window is opened a bit better, shut washed-up. Shut washed-up..

Under photograph comparing, ding Lin more apt new technology. "Through the search, her lock decided the suit that divide aldehyde, " include to divide light of modified of rice of aldehyde sparge, accept catalyst and furniture divide flavour elite, can take formaldehyde member allegedly, still can use biology catalysis to decompose a technology, resolve the harmful matter such as formaldehyde into water and carbon dioxide, though I also not quite understand, but sound quite ' lofty on ' . But sound quite ' lofty on ' ..

Ding Lin the furniture in house in turn gush, buy again advocate make the air purifier that divides formaldehyde function, keep leaving day and night. After a month, she is invited detect technically orgnaization sampling analysis, "The result comes out, still be formaldehyde exceeds bid unexpectedly, can consider other measure again only. Can consider other measure again only..

"According to the regulation, detect professionally the tool needs to get ' CMC ' attestation, namely ' People's Republic of China creates metrological implement license ' mark, but at present the formaldehyde on market detects the tool does not have such aptitude almost, product quality have no way assures, measure the outcome that come out often suspect. " condition of indoor car core and Song Ansheng of director of center of environmental protection product quality supervision and inspection represent the state, formaldehyde detects very tall to the sensor requirement of the instrument, every value counts the instrument that normal lab uses yuan, and sell on the net detect tool the structure is normally simple, the interference factor such as airy velocity of flow, humidity, temperature is possible very big to arising as a result impact, plus undertake calibration without professional lab, accuracy also is mentioned with respect to have no way.

As we have learned, former state pledges check total bureau ever organized the venture that develops product of detector of indoor to net carry out harmful material to monitor last year, the 30 batch that detect randomly hold formaldehyde detector sample to all be not had " CMC " attestation. All products fail accurate detect the actual concentration that gives formaldehyde, TVOC, major sample is exaggerated even measure precision, put in quality hidden trouble.

"A few companies allege can take professional equipment to come to detect, give a result on the spot even, main purpose is to promote so called remove formaldehyde product, let consumer very easily be deceived. " Song Ansheng expresses, formaldehyde detects ought to look for the orgnaization that has national level or level of provincial and metric attestation, the tripartite that takes metric attestation certificate of conformity only detects orgnaization, just have the lab that accords with national level, allow to examining use on the report " CMA " (the English abbreviate of Chinese metric attestation) chapter, and such report just has legal effectiveness, "According to the requirement, the member that the spot should have two sampling, and want groom through major, not be informal what person takes an instrument to be able to be done. Sampling and analysis also must be apart, avoid subjective element effect. Avoid subjective element effect..

Divide formaldehyde way variously in the light of items, song Ansheng points out among them the error is heavy. "Although activated carbon has certain sorption, but belong to passivity to purify material, indoor air fluidity compares poor condition to fall, short time takes the harmful matter in be apart from further air very hard, effect very little is used in the large space that open wide, basically ought to use at the chest, drawer little space that closes relatively. " Song Ansheng still reminds, activated carbon is not stable to the adsorption of formaldehyde, once reach saturation, harmful gas still can be released again, instead causes pollution 2 times, because this must change in time.

Get the green plant of praise highly as to equipment, shi Jun of doctor of institute of plant of the Chinese Academy of Sciences also Ceng Zhuanwen points out, although the plant such as bracketplant has certain absorption formaldehyde ability, but ability is quite limited, can't reduce the formaldehyde concentration inside general bedroom significantly inside short time.

"Still the formaldehyde such as smooth accelerant of a few such as eliminates an agent, also cannot use blindly. " Song Ansheng expresses, at present the state has not shut to keep clear of at formaldehyde the relative standard of agent respect, the good and bad are intermingled of this kind of product on market, so called smooth accelerant also is stunt likely, will surely not remove formaldehyde not only, controversy also exists on security.

Song Ansheng still points out, market get on a lot of flaunting to have " except formaldehyde " functional air purifier is not reliable, "Great majority alleges the air purifier that can remove formaldehyde, it is to be above the efficient filter of purifier spray the material that purifies formaldehyde, appear very easily the circumstance of adsorptive saturation, after also meaning use period of time, the property that divides formaldehyde can become very faint. The property that divides formaldehyde can become very faint..

"From the point of the effect, open a window ventilated or it is certain that system of installation new wind is reducing formaldehyde chroma respect to rise really action, but this still is not to settle way at all. " Song Ansheng expresses, because use unqualified data in great quantities,be, so although on air two years also of no help. More what is more,the rather that, below microtherm condition, of the harmful material such as formaldehyde release a quantity very low, when winter heating or get warm again after a cold spell of air temperature of the coming year, formaldehyde chroma or meeting are elevatory, because this key still wants to ask professional to locate contaminative source, undertake having the processing of specific aim. In the meantime, in decorating a process, also want to choose the new material with formaldehyde relatively inferior content, new technology as far as possible, try to control from fountainhead.
