The person that the formaldehyde detector that the net buys lets use " chart is done not have in the heart "
The house that freelies foster cordial relations between countries of will firm outfit, formaldehyde exceeds bid is rental, create tenement body unwell. Because be hired,even family member of the staff in A suspects family " freely formaldehyde room " die, preparation sues freely. For a short while formaldehyde detects become attention heat once more, many citizens in succession the net buys formaldehyde detector to undertake detecting to the house of oneself. Nevertheless, beijing youth signs up for " lab of finance and economics " the experiment discovery that the column passes pair of 7 paragraph nets to buy formaldehyde gift, these detectors cannot offer exact formaldehyde numerical value. Professional personage also points out related, the portable formaldehyde detector that the net buys is electronic component only more very is simple and medley, measure the result that give to basically do not rely on chart.
Recently, freely is exposed to the sun to give the house that fosters cordial relations between states firm outfit to rent quickly, building formaldehyde exceeds bid, tenement appears the body such as allergy of giddy, skin, guttural gall is unwell. New clothes repairs building formaldehyde problem to become a heat that the citizen pays close attention to quickly. And simple and easy and portable net buys formaldehyde detector to had become a lot of citizen families to detect the first selection of formaldehyde, and does this kind of simple and easy method rely on not to rely on chart after all? Beijing youth signed up for reporter net to buy 7 formaldehyde detector, try to get the result with the means of the experiment.
The net purchases formaldehyde detector numerical value " rove "
In daily life, citizen new clothes repairs a house to buy furniture newly perhaps, for healthy consideration, always want to measure formaldehyde. They measure the method with the most commonly used formaldehyde is the net buys detector of a formaldehyde. So, is this kind of way that measures formaldehyde reliable?
Ms. Yao bought a piece of new bed that spreads up and down first half of the year this year, new bed is in the period of time that has assembled, as a result of the existence of peculiar smell, ms. Yao that there is a child in the home fears whether the formaldehyde in the room can exceed bid all the time. Below the friend's commendation, she bought detector of a formaldehyde in the net that clean out treasure. Ms. Yao begins to be in the room by the step that takes a manual open formaldehyde detector.
What Ms. Dan Lingyao did not think of is, the digital rove on formaldehyde detector. Just beginning to measure is 0.009mg/m3, crossed the position with same quarter to detect number however violent wind rose 0.098mg/m3, crossed a number a little while to become 0.071mg/m3 again again, highest when achieved 0.15mg/m3 for a time, the standard of outclass country is worth 0.08mg/m3. Detected result lets Ms. Yao more headache, after all which number is just true?
Fall in the introduction of friend of qualitative inspect bureau subsequently, ms. Yao looked for a major to measure the orgnaization of formaldehyde, this furniture has CMA attestation detect the orgnaization lets Ms. Yao sealed door ahead of schedule window 12 hours, taking professional equipment to come to detect next, a test point collects fees 200 yuan, altogether 400 yuan, the detector that buys than Ms. Yao net is cheap still 100 yuan. After a week, detect the report gives heat, two monitoring point of Ms. Yao home advocate lie and second lie. Among them advocate lying formaldehyde numerical value is 0.06mg/m3, second lying formaldehyde numerical value is 0.08mg/m3, all accord with a standard, ms. Yao loosened finally at a heat.
See beside after increasing friend is decorating a building, choice net buys a detector to measure formaldehyde, ms. Yao generated doubt, does the portable formaldehyde detector that the net buys have the effect after all? If there is the effect why is so much businessman selling?
Experiment
7 nets buy formaldehyde detector to detect result " completely different "
Does the net buy formaldehyde detector to allow to forbid after all? Buy the secret of formaldehyde detector to open a network, boreal blueness signed up for a reporter to do a simple test. Boreal blueness signs up for a reporter to be in clean out treasure, Beijing east wait for a net to buy platform discovery, the formaldehyde detector price that making work on the net differs to hundreds of yuan from a few yuan. "The unified calibration of professional equipment is passed before leaving factory, use convenient; Testing system of SEN algorithmic air " " technology of United States of research and development of group of Chinese Academy of Sciences " " use technology of sensor of flow of gas of high accuracy interference rejection " " double 1000 nicety detect " " all-around enclothe air quality to detect " " 4 nucleuses pass feeling technology " wait a lot of " lofty go up " .
Platform is bought to go up in these a few nets, reporter of boreal blueness newspaper bought 7 formaldehyde detector to have a test as test specimen according to different price. Include detector of Xin Lian formaldehyde (59 yuan) ; Agee general is indoor formaldehyde detector (79 yuan) ; Censorial GT58 (79 yuan) ; Set one's mind at treasure formaldehyde detector (299 yuan) ; Detector of Jia Bailan formaldehyde (168 yuan) ; Core of be in harmony detector of wisdom feeling formaldehyde (239 yuan) ; Detector of green quality of predestined relationship air (888 yuan) . Detector of these 7 formaldehyde basically covered the brand of the different price before sales volume leans.
Boreal blueness signed up for the as it happens in reporter home to buy a new furniture, to assure the fair sex of the test. Reporter of boreal blueness newspaper is strict the manual according to each detectors, be in airtight room after 12 hours the following day in the morning, in same the position opened detector of these 7 formaldehyde. Test room temperature is 25 degrees, humidity is 40% .
Detect the result shows, home Xin Lian detects with the formaldehyde of formaldehyde detector the value is 0.101mg/m3; Agee general is indoor the formaldehyde of formaldehyde detector detects the value is 0.043 Mg/m3; The formaldehyde of censorial GT58 detects the value is 0.112 Mg/m3; Set one's mind at the formaldehyde numerical value of treasure formaldehyde detector is 0.051 Mg/m3; The formaldehyde of detector of Jia Bailan formaldehyde detects the value is 0.003mg/m3; Core of be in harmony the formaldehyde of detector of wisdom feeling formaldehyde detects the value is 0.16 Mg/m3; The formaldehyde of detector of green quality of predestined relationship air detects the value is 0.026 Mg/m3. Of these 7 detectors detect there are two any numerical values in the result is identical very adjacent perhaps.
According to national formaldehyde acceptable standard:
And the TVOC of 6 detectors (total volatile organic matter) detect numerical value is completely different also. In same time, same place, the TVOC value of detector of formaldehyde of Xin Lian family expenses is 0.085 Mg/m3; The TVOC value of indoor formaldehyde detector is Agee general 0.319 Mg/m3; The TVOC value of censorial GT58 is 1.199 Mg/m3; Set one's mind at the TVOC value of treasure formaldehyde detector is 0.243 Mg/m3; The TVOC value of detector of Jia Bailan formaldehyde is 0.008 Mg/m3; The TVOC value of detector of green quality of predestined relationship air is 0.137 Mg/m3. Detector of wisdom feeling formaldehyde does not have core of a be in harmony TVOC detects project.
Boreal blueness signs up for a reporter to still notice a detail, if to formaldehyde detector breathe out, the numeric meeting of partial formaldehyde detector carries quickly litre, react the most intense is censorial GT58, rose very quickly 0.18 Mg/m3 left and right sides. The quality of predestined relationship air with detector of wisdom feeling formaldehyde, green core of detector of formaldehyde of family expenses of detector of Jia Bailan formaldehyde, Xin Lian, be in harmony the detector detect the number can observe slight rise; Agee general is indoor formaldehyde detector, set one's mind at treasure formaldehyde detector does not have reaction to this.
Boreal blueness signs up for a reporter to return discovery, the number that these detectors show is not stable, lie between period of time to be measured again, these numbers produced change again, data ignore tall ignore low, appear even partial detector detects last time show for 0, detect the next time the circumstance that exceeds bid however.
The course experiments for many times, a when boreal blueness signs up for a reporter to cannot get the formaldehyde in the home through these 7 detectors accurate perhaps say probably numeric. These detectors cannot offer exact formaldehyde numerical value, achieve the result of expect hard through detector of formaldehyde of portable family expenses.
Dispel misgivings
Why does the net buy portable formaldehyde detector not to rely on chart?
Why does the net buy portable formaldehyde detector to forbid? Yesterday, the director Song Ansheng of condition of indoor car core and center of environmental protection product quality supervision and inspection is opposite the country boreal blueness signs up for a reporter to express, the portable formaldehyde detector that the net buys is uneven, general accuracy extreme difference. Detector of formaldehyde of a lot of family expenses is electronic component only is simple and medley, use function to infect feeling cell inferiorly not only, and put in the market below the case that did not pass systematic demarcate and test, measure the result that give to basically do not rely on chart.
Song Ansheng expresses, sensor of use gas pollution comes to the net buys portable formaldehyde detector detect, this is very sophisticated technology. Structure of portable formaldehyde detector is simple, the requirement that far short of detects accurately. This kind of detector suffers all sorts of interference element impact is very big, the accuracy that metropolis logarithm occupies airy velocity of flow, humidity, temperature produces great effect, plus undertake calibration without professional lab, accuracy is couldn't get basically assure.
The detector of normal now lab has two commonly, produce respectively from England and United States, every price goes to 20 thousand yuan in 10 thousand yuan about between. Sensor technology of home returns the requirement with corresponding short of at present.
"Formaldehyde detector sells everywhere on the net now, these instruments use value without what mostly " , song Ansheng expresses, at present our country did not stipulate civil portable detector needs to appear on the market again through attestation, because this is whole market lack is normative, randommer. The country should publish relevant provision to come standard this market, if do not have any effects certainly, should prohibit selling, if this kind of way is efficient, should establish corresponding standard.
Proposal
Measure formaldehyde to look for the professional orgnaization that has attestation even
So, if are this decorated to measure indoor formaldehyde in citizen home to if how are this decorated to measure indoor formaldehyde in citizen home,exceed bid? Song Ansheng expresses, the citizen should detect formaldehyde, the formaldehyde that still should look for major detects orgnaization, and must search have the orgnaization of national level or standard of provincial and metric attestation. In the introduction of a lot of orgnaizations, can appear " CMA " (the English abbreviate of Chinese metric attestation) label. The tripartite that takes metric attestation certificate of conformity only detects orgnaization, just have the lab that accords with national level, allow to examining CMA rule is used on the report. Build those who have CMA order to examine the report can be used at product quality evaluation, achievement and judicatory appraisal, have legal effectiveness.
To detected process, song Ansheng introduces, the citizen buys bridal chamber to perhaps undertake bridal chamber is decorated, want to see indoor environment whether amount to mark. If ask,detect professionally orgnaization, need shifts to an earlier date will indoor have a hour after closing, ask central professional to arrive again spot sampling. Detect content basically includes 5 essential factor such as formaldehyde, benzene, ammonia, radon and volatile organic matter. After passing the 30 spot sampling that arrive 40 minutes, the staff member is met sample book resumptive lab has an analysis, can issue a result inside 3 weekday usually. If be new,acquired furniture, or it is new installed air purifier, want to measure the air quality in surveying the home. According to the country " indoor air quality " standard, detect flow and new clothes repair house likeness, what differ exclusively is, detect in this kind before beginning, indoor need closes 12 hours.
Song Ansheng warns a citizen at the same time, at present many formaldehyde on market detect the orgnaization is more confused also, company of a lot of processing is to be being taken a few allege " professional " portable detector comes to detect, give a result on the spot, tell a citizen indoor sky is gassy in the home besides. If the citizen does not understand this, be deceived very easily. "A few cheater detect orgnaization, can promote after detect even equip except formaldehyde, say to be able to come administer formaldehyde, actually the country sets those who want departure to detect and be being administered is " .
Clew
How simple and easy the formaldehyde in dividing the home?
On October 27, 2017, the carcinogenic substance detailed list that research organization of cancer of international of World Health Organization publishs is initial arrange reference, formaldehyde is in detailed list of a kind of carcinogenic substance. Formaldehyde causes easily: Guttural and unwell, guttural gall, bosom frowsty, jealous, eye the numerous disease such as urticant, dermatitis.
No matter choose why to be planted,decorate a style, decorate Chengdu to escape hard the destiny that indoor formaldehyde pollutes. Likelihood somebody thinks is not to decorate meet occurrence pollution, should notice to use environmental protection only material, much at ordinary times ventilated can avoid formaldehyde exceed bid. But actually, formaldehyde is consist in when we are decorated, those who use is of all kinds decorate, in decorating material.
How to reduce the formaldehyde in the building. Boreal blueness signs up for reporter course to ask professional public figure with all possible means, reach the formaldehyde in administering the home simply has the following kinds of methods roughly.
1. fountainhead is controlled, the environmental protection product of high quality selects when decorating, especially plank furniture, floor and lacquer.
2. opens a window ventilated. If the furniture in the home is more, regular however not ventilated take a breath, can bring about the accumulation of formaldehyde very easily. Additional, because formaldehyde is in high temperature is high wet environment issues ability to volatilize quickly, and temperature under 19 degrees, the volatilization of formaldehyde is measured very little, so reasonable idea is to raise room temperature and indoor humidity, room temperature 28 degrees of above, humidity 70% above, formaldehyde can volatilize more quickly come out, maintain high room temperature and humidity, airtight 12 hours, open a window next ventilated, such loop move back and forth can achieve better result.
3. can use a part to contain go the air purifier of formaldehyde function. Reduce the formaldehyde content in indoor air through purifying airy means.
The green plant such as orchid, green trailing plants, ivy, cacti, bulrush is put more in 4. room, can improve air quality.
5. puts activated carbon package in the cabinet that close, drawer.
6. puts some of state dimension brilliant in the home, it is the personage inside environmental protection course of study's commonly used adsorption discloses data, its adsorption sex is strong, adsorptive amount is large, state dimension brilliant can decompose the contaminant such as adsorptive formaldehyde thoroughly, purify air continuously for a long time more conveniently.
