On December 12, 2017, freely rents the room is exploded to give formaldehyde to exceed mark issue.
After appearing for this news below, I am a foundation with this news, a when write about " decorate pollution " and " formaldehyde detects " long article.
Although news time passes and the situation has changed, but the understanding to formaldehyde, still be opposite everybody is applicable!
-- -- -- -- -- --
In the meantime, this also reminded us again:
" decorate pollution " this baneful influence is all the time beside us, never far go!
You leave all these, the likelihood is only poor " detect " !
Hire freely first room incident is answered simply put, the friend that the side had not dogged combs next gist:
(below it is repeat only the content of media, there is a few inside " problem " , can tell in detail at the back of me)
1, on December 12, media head signs up for, the one student that rents a house in freely is brought about because of air stimulation " acute is bronchitic " . Bought an instrument to measure formaldehyde to exceed bid oneself 3 times, looked for major to detect discovery exceeds bid likewise. 2, freely chamberlain communicates a hope to do primary air processing, student and its neighbour do not agree, think " purify formaldehyde can use physical method only, cannot chemically method " . 3, the reporter is taking portable formaldehyde detector, turned again the other and rental room that a few each are like, all discover existence formaldehyde exceeds mark phenomenon. 4, reporter freely chamberlain is communicated in order to hire for the room, get a paragraph of answer: "If you bring a child, I do not suggest you live freely. Still search common, may that numerical value amounts to mark, but still do not suggest... the problem that decorates namely. " 5, before this, because,freely same question, hire a guest to sign with reconcile agreement, one-time pay more than yuan 40 thousand " use as damage " . 6, in July 2015, lady couple is hiring freely after 3 months, by fish severe anemia, be by diagnose after leukaemia, must will fetal induced labor. Engage in a lawsuit, held the post of a lady to be defeated, but freely freewill compensation gives a lady 150 thousand yuan. 7, on December 13, media phonates once more: Exceed the superintendency vacancy of mark about rental room formaldehyde at present, appeal enterprise self-communion, the hope complements as soon as possible relevant law laws and regulations. 8, on December 14, media signs up for again, freely room decorates cycle 30 days, the inadequacy that put flavour rents 3 days, chummage is more expensive than be not freely 2 into, everything is " look to money " . 9, the literal material that the sound that freelies the public relations that rent a house gives China sends: The furniture plank that freely can ask all suppliers are offerred must accord with the E1 class plank of standard of national environmental protection; The metope coating such as emulsioni paint uses Li Bangqi; The floor uses aggrandizement plank of class of E1 of compound international environmental protection.
What after looking, feels?
Feel happy oneself do not have rental room, because be hired likewise,still feel back hair is cool?
Have the impulse that a detector buys to survey him home on one stallion?
Formaldehyde exceeds bid too terrible, after all what disease can formaldehyde cause?
The E1 class plank that freely says, what be after all?
...
One looks be like simple social news, point of backside hidden knowledge is simple not at all however!
Decorate knowledge to leave us too far, but decorate pollution to be all the time however beside.
Why to say " decorate pollution to leave you only poor " detect " " ?
The answer some you can be conceivable, but some you however not likely can think of...
Below, I will take everybody below understanding " detect " of backside " consumptive trap " !
(see you guess was opposite how many ~ )
1, " detect " exterior trap:
The material of so-called environmental protection, can you still bring about formaldehyde to exceed bid for what?
(the friend that begins to consider to decorate, the existence that 50% above know this pitfall)
All previous classics decorates contaminative ablution and education more than 10 years, we go buying when decorating material, normally metropolis care issues this data whether " environmental protection " .
Because the businessman is ordinary not quite authentic, so we can ask the businessman shows the evidence that proves material environmental protection normally, this moment, some businessmen " enlarge is enrolled " , they can say: You can detect, detect exceed bid, we go out detect cost, sum refund!
Although detect freely,look very inviting, but actually however " stunt " be more than actual.
Why saying this kind detects is a stunt, I will to everybody analyse below:
1) material detects and pledging into the air after living the quantity detects is two different matters, is what businessman and you agree what after all?
Before, be willing to hit this most " stunt " , often be furniture company. In all sorts of data that because the home is medium,use, furniture is authentic least of all, especially board type furniture.
Crossing what point to as a result of these enterprises to detect is to be aimed at material mostly, is not indoor air, and should detect material still needs to undertake destructive sampling to furniture, so consumer carries out this kind very hard to detect truly.
Now, a lot of decorate a company to begin follow-up this kind " stunt " , but they are aimed at only " hard outfit link " detect. Before door of ambry, wood, floor, furniture did not enter the arena, do indoor air quality to detect. Because do not have what basically to have contaminative stuff, and detect freely more or less does tripartite also have a problem with use instrument or collaboration, percent of pass is very so tall.
But for this pair of consumer, the sense is not great.
2) if air detects when there still are other data in the home, detect who to exceed mark to be?
If owner is truer, be about to seek certain consent detected businessman undertakes " air detects " , and the tripartite that rejects to use a businessman to offer detects orgnaization, oneself searched to be worth newcome to detect more square... the result exceeds bid, the businessman also has actually answer way.
After all, general authority is installing forcedly + after furniture ends, just undertake detecting, so hard to avoid is in with respect to memory of conference occurrence room a variety of circumstances that pollute a source. For instance, lacquer having a wall, floor, furniture is waited a moment. The result with final even if is air exceeds bid, any manufacturer also won't admit the material that is his has a problem, metropolis requirement undertakes afresh " the product detects " .
This goes up with respect to the old road that returned businessman place to be good at!
3) the data that single product perhaps uses does not exceed bid, whether can air amount to mark?
Ask everybody to must realize: Decorating pollution is the result that overlay accumulates effect, even if every are planted in the room,material allows to fall to amount to mark in mark of him material check, but airtight in a microenvironment, the contaminant in still bringing about final air possibly exceeds bid!
So, below probable condition, choose those to be able to be accomplished completely as far as possible " 0 contaminant " material, is not those " low pollution " but can " amount to mark " material.
For instance, floor and floor tile photograph are compared, floor tile is 0 pollution, the floor is low pollution.
For instance, woodiness and metallic photograph are compared, the metal is 0 pollution, woodiness is low pollution.
For instance, wall paint and diatom mud photograph are compared, diatom mud is 0 pollution, wall paint is low pollution.
(every kinds of material has above to discern in detail with fractionize, do not see literal only, detailed everybody can browse the knowledge that has sent before me is stuck)
Your home distance decorates pollution to be differred only " detect " , believed when you material environmental protection is only perhaps after tasting environmental protection, air still may exceed bid. And, of businessman acceptance " detect freely " , probable it is stunt.
2, " detect " obscure pitfall
The reporter takes the portable formaldehyde instrument of the move, seem pretty good?
(can realize this kind of instrument has a problem, estimation is less than 20% ... )
Face what exist possibly to decorate pollution, if a kind of instrument can help us judge ambient air to whether be put in formaldehyde to exceed bid quickly, can you solve a lot of problems? Sound it seems that very rely on chart! ...
But reality often very brutal: Can buy on market " formaldehyde instrument " , 95% above do not rely on chart!
Include X capital the newspaper takes in reporter hand that, so-called be " tall nicety " the thing of air quality detector, it is a jest substantially.
" formaldehyde checks " civil product, have probably on market so a few kinds:
1) VOC detects yuan of parts of an apparatus, qualitative judgement.
Everybody can be mixed in some treasure some east on the formaldehyde instrument of bought 90% above, it is use this is planted yuan of parts of an apparatus.
Ten yuan of this kind of cost petty gain of yuan of parts of an apparatus, a few expensive yuan. The function is ambiguous measure an one big bill the existence of organic matter, but what cannot judge existence accurately after all at all is which kinds, and after all how many does chroma have.
So if before you more than when, the data that you can discover to they show is different, and, no matter how are you moved,also do not have method to let them " reach consensus " .
Hold out high-tech it seems that, but substantially, go checking data with this kind of instrument, it is a jest!
2) formaldehyde checks a box, qualitative + mensurable judgement.
Formaldehyde test case appears than formaldehyde instrument even a bit earlier, those who use is " phenolic reagent " undertake colorimetric detects.
From chemical principle for, direction still is special desirable. Just check a box as a result of formaldehyde can the static state is put, if the room when the test is airtight time is insufficient, reaction condition is improper, final result can appear bigger error.
Before the test case that there is a kind to take inflator to collect oneself on the net, come from the operation say, be close to the aeriform sampling method in GB quite, data should be met be close to the truth more a few.
Say to still cannot calculate ration completely, because final " colorimetric " link can judge the precision of 0.1 probably only, even if give out referenced color is more, also of no help. But 0.1 milligram / stere above has exceeded bid!
3) entrance electrochemistry detecting element, mensurable judgement.
If everybody can wait, the formaldehyde that buys a few different brands more actually checks box patience to do a test, also be possible.
But if cannot wait, also believe ambiguous data not quite, in the meantime, feeling beautiful to hundreds of money are close to data truth more is worthiness, that can try use " entrance electrochemistry yuan parts of an apparatus " formaldehyde detector.
Current, this kind " entrance electrochemistry yuan parts of an apparatus " refer in particular to " England Drat formaldehyde checks Dutt component " , be still make do with in accepted low price a kind of product that can use.
Remind mainly again below: Even if is hitting Dutt the stunt of sensor, the product of all some cat inn is inferior to some treasure possibly instead more authentic. Formaldehyde detector chain of this gray increase is too long, the DIY product on some treasure that was not commercialized adequately is a few more authentic instead. Mix in data stability at least consistency (much platform instrument agrees with environmental data) on, those who do is betterer. Under 300 yuan, ask direct oversight.
4) photometry of test paper photoelectricity, essence of life measures judgement certainly.
At present in this domain, the comparison that do is good, and sexual price is higher than still be being compared, it is Japanese manage grinds subordinate FP-30 series. FP-30-C is to go up generation product, price lowest is in 7000 the left and right sides, this generation is FP-30MK2 (C) , minimum price also should be in 10 thousand above. Electric business platform also can search arrives, but main sales volume is 0.
Still used portable design considering this equipment, it is a civil detector constrainedly so... actually the price already very " professional " .
Reiterate:
All electronic formaldehyde detectors of a few, besides few number you can be watched continuously used England Dutt electrochemistry detects outside the DIY product of yuan of parts of an apparatus, other uniform do not rely on chart. If time there's still time, check paper as use formaldehyde check. Of course, most those who rely on chart is photometry of test paper photoelectricity, but the instrument is too expensive, lowest 7000 above, suit Everyman family expenses not quite.
(limited space, about testing instrument, introduce these first, everybody has what inquisitive, although carry,leave a message! )
Your home distance decorates pollution to be differred only " detect " , when the formaldehyde detector that you want to buy a petty gain, what buy probably is rubbish. Not only cannot give you accurate data, return meeting misdirect your judgement.
3, " detect " trap exceeding hole
Look for the sort of major to decorate pollution detects and administer, rely on chart?
(there is intelligence quotient duty already inside this, also have bilk, understand those who cover a region to be less than 5% )
Although before two trap also very hole, but do not have the last hole absolutely.
If say, after many woodiness data is being used in the home, existence pollution exceeds bid is inevitable almost;
If say, want oneself to buy cheap formaldehyde instrument, do not have method basically to measure an outcome;
So, , look for a company that undertakes major detects to rely on chart?
Progress as the society, was born really one batch, can offer the orgnaization that air detects. Some wants yourself sampling only even, express can have a test to them, be less than 200 yuan a sampling, and still playing SGS banner, pretty is inviting!
(this I also had not tried, if have has tried friend, can give tell tell)
But still have a large number of " very frame-up compasses " detect orgnaization.
Normally, want to be able to judge this kind detect at 2 o'clock only the normal sex of the orgnaization:
1) whether besides detect besides, return those who offer any forms to decorate contaminative solution (include seek advice) .
Cannot say this is planted 100% have a problem, but if so-called " detect freely " , that is more suspectable.
The world does not have free lunch, always can do what detect freely, regular meeting earns money through other form come back. Not avaricious!
2) use why to plant equipment undertakes formaldehyde pH indicator detects, whether to rely on chart.
Low of a bit, although equipment chest looks very tall and big,go up, but still be colorimetric law.
Of midstream level, have the facility of a prismatic photometry at least, a few more advanced.
Of big ox is chromatically chart analysis, what can give CMA to report is basic want this paragraph.
With above 3 school are different, there still is a kind to look on market equipment is very professional (metallic casket) , all sorts of mechanism pushbutton, but still be instrument of common electrochemistry electron substantially. The price is 800-2000 probably yuan between.
This genre has a marked characteristic: The device that they use, have oneself to adjust the ability of reading!
If you go detecting to a new client, so OK " increase " , make his home all exceed bid!
If you go to making the client home that administer or used data, that is OK " key is low " , make sure all data amount to mark!
...
Actually, make a holiday namely!
Your home distance decorates pollution to be differred only " detect " , if you found this kind of company that relies on to administer kite unfortunately, that detects this is one field fraud begin. It is a play from A to Z, everybody is an actor.
Finally, we are summed up, to escape " detect " the trap that exists possibly, how should we do:
1, fall in probable condition, use woodiness data less as far as possible, especially cheap and inferior plank. If can need not woodiness material, also do not involve carpentry lacquer (the carpentry lacquer of surface of certain reality wood is likely the question is bigger, involving benzene is content) , decorated contaminative problem to exist scarcely. 2, furniture uses a metal, ground floor tile- paving tile, metope uses diatom sludge, common air pollution is met probably " clear " . (the hole of diatom mud is more also, not as good as the market of formaldehyde detector how many, not informal skill) 3, the businessman says " detect refund of sum exceeding bid " , probable it is an empty talk, do not have maneuverability already, be denied easily also. 4, the formaldehyde detector on market did not rely on chart almost, part of 300 yuan of above abstain DIY England sensor detector returns Dutt to be able to be used constrainedly, the Japanese manage that wants to rely on chart to be about to buy nearly 10 thousand yuan truly grinds Fp-30. 5, formaldehyde checks a box, be no problem on experimental principle, just restrict as a result of use method, and data is more ambiguous, so odd second detect the sense is not great, many products compare best and different brand repeatedly for many times right, just be close to the truth possibly more. 6, always with " air pollutes processing " those who be a target, any " air quality detects " do not touch, even if the other side tells you " free " . Free it is the largest hole! 7, can give CMA to report, using is prismatic luminosity cooperates color atlas perhaps is color atlas method to detect at least, check to formaldehyde chroma, just be rely on chart. 8, above did not tell, but you also should know: Formaldehyde is not to decorate the most terrible in pollution, the air that decorating even is not the most terrible in pollution, even if formaldehyde exceeds bid, also do not want too fear, what may do not have you to want is so fearsome. 9, if formaldehyde exceeds bid, besides look for a businessman to solve, oneself are OK still: 1) remember, open a window ventilated it is to lower formaldehyde pH indicator best method, the others any methods are compensatory. Want you to be able to open window 6-8 everyday only second, every time 5-10 minute, formaldehyde exceeds mark to leave you far. 2) if as a result of special account, cannot in the late evening or other time has a window ventilated, you also can carry the kind of use air purifier, through letting purifier filter indoor airy means reduces formaldehyde concentration. 3) the problem exceeding bid of TVOC also is worth to pay close attention to very much, also had better affirm. Must not know formaldehyde only!
-- -- -- -- -- -- ,
Decorate live daily in us with respect to be in harmony in the center, but a lot of professional knowledge are understood not quite easily however.
Lending this second news, helped everybody comb dot of a few knowledge, and make it " title " form, let study a bit new move.
5 news concern, 5 this piece the article concerns, everybody can be measured oneself
(the answer can leave a message write, be " play card " )
[news is relevant]
1, E1 plank is material of a kind of environmental protection, use E1 plank won't cause formaldehyde to exceed bid. ()
2, after been decorate, need undertakes putting flavour, generally speaking 3 days enough. ()
3, purify formaldehyde to cannot be used " chemical method " , must want to use " physical method " . ()
4, the material that formaldehyde is a kind of special dreariness, can let a person get leukaemia. ()
5, emulsioni paint uses Li Bangqi compare environmental protection, won't cause formaldehyde to exceed bid. ()
[this piece relevant]
6, use woodiness material causes formaldehyde easily to exceed bid, even if sheet tastes formaldehyde qualification, air still may be brought about to exceed bid after gathering. ()
7, if want to buy formaldehyde detector, on the net under 300 yuan do not rely on chart, but of 300 yuan of above be no problem commonly. ()
8, in detector of current and civil formaldehyde, data is most accurate is photometry of test paper photoelectricity, representing a brand is England Dutt. ()
9, processing air pollution, should look for to rely on chart above all come to detect orgnaization, can detect freely commonly. ()
10, formaldehyde is the number one killer in indoor air pollution, wanted to eliminate formaldehyde only, air was no problem. ()
Right answer is falling period announce, expect please!
Write finally:
This is an attempt, try to pass heat of a few news, make everybody right decorate many somes of understanding.
We still are met after more close together track similar news heat, accompany everybody to change an angle to read news.
Decorating pollution is everybody all the time one of problems that in decorating, pay close attention to most, but in sale bomb of the businessman and social morbid state attention falls, real knowledge " decorate pollution " the person that is what, not much.
Both neither wants demon to change " decorate pollution " let some many person borrow machine get rich, undeserved benefit;
Not blind also hopeful, oversight " decorate pollution " the result lets very the evening of person regret;
Should not detecting more and eliminate " decorate pollution " when be deceived, apprentice increases trouble.
This is the original idea that I write this content.
