Cov khoom siv tsheb tuaj yeem ua haujlwm ib txwm nyob ntawm qhov kub thiab txias, tsuas yog 3M kua nplaum yuav cuam tshuam zoo heev. Niaj hnub no, peb qhov kev ntsuas kub kub yog feem ntau yog tsom rau cov concentration ntawm cov organic tebchaw tsis muaj zog (tom qab no hu ua VOC) ntawm cov khoom.
Ua ntej, lub tsheb kub kub mus rau hauv cov pa roj chamber?
Peb txhua tus paub tias yuav muaj ntxhiab tsw ntawm qhov kub thiab txias hauv lub tsheb, ib feem ntawm qhov laj thawj yog los ntawm cov ntsuas ntsuas hauv lub tsheb, qhov rooj sab hauv vaj huam sib luag, pem teb qab nthab, thiab lwm yam, yog tias siv tawv, sponges, roj hmab. thiab lwm yam ntaub ntawv uas tsis ua raws li ib puag ncig tus qauv, nws yuav emit benzene, toluene, xylene, styrene thiab lwm yam teeb meem gases (volatile organic compounds) txhua lub sij hawm.
Yog li ntawd, cov thawj sab hauv cov khoom no yuav raug soj ntsuam nruj me ntsis ua ntej tawm hauv lub Hoobkas kom tsis txhob muaj cov pa phem thiab ua rau cov pa phem hauv lub tsheb.
Nyob rau hauv sib piv, cov khoom ntawm lub tsheb tom qab khw muag khoom feem ntau tsis tau guaranteed tom qab lub installation ntawm cov ntaub ntawv nyob rau hauv lub sab hauv, thiab nws yog yooj yim dua tso cov pa phem nyob rau hauv lub caij ntuj sov kub ib puag ncig, uas ua rau lub hauv siab nruj thiab mob taub hau rau lub tsheb neeg ua hauj lwm.
Thiab vim tias qhov xwm txheej ntawm cov pa phem hauv lub tsheb tom qab kev teeb tsa cov khoom siv hauv tsheb, qhov chaw ntawm cov pa phem yog qhov nyuaj rau kev soj ntsuam, thiab qhov tshwm sim tsis tuaj yeem raug them los ntawm lub Hoobkas tsheb, thiab tsuas yog xav txog lawv tus kheej tsis muaj hmoo. Yog li, VOC tso tawm ntau yam khoom siv tom qab sib dhos hauv lub tsheb ntawm qhov kub thiab txias yog lub hom phiaj tseem ceeb ntawm peb qhov kev tshawb nrhiav.
Raws li Ministry of Environmental Protection thiab General Administration ntawm Kev Tswj Xyuas Zoo, Kev Tshawb Fawb thiab Quarantine tau koom ua ke tshaj tawm "kev xav tau ntawm cov organic sib xyaw ua ke hauv huab cua hauv lub tsheb", formaldehyde hauv lub tsheb yuav tsum tsis txhob siab dua {{0} }.10 mg/m³. Yog tias cov ntsiab lus formaldehyde hauv lub tsheb siab dua 3 mg rau ib lub cubic meter, nws yuav ua rau tib neeg tsis xis nyob, thiab cov menyuam yaus thiab cov pab pawg rhiab tuaj yeem ua rau mob hawb pob.
Txhawm rau kuaj cov organic concentration ntawm txhua yam khoom, peb xaiv los ntsuas lawv hauv lub thawv kuaj, yog li cov ntaub ntawv zaum kawg yuav txawv ntawm qhov tsis haum xeeb hauv lub tsheb ib puag ncig, tsuas yog siv rau kev sib piv ntawm cov khoom.
Concentration ntawm volatile organic compounds (unit: mg/m³) Yam khoom Concentration Requirements Benzene Tsawg dua lossis sib npaug rau {{0}}.11 toluene Tsawg dua lossis sib npaug rau 1.1{{10}}} xylene Tsawg dua lossis sib npaug rau 1.50 ethylbenzene Tsawg dua lossis sib npaug rau 1.50 styrene Tsawg dua lossis sib npaug rau 0.26 formaldehyde Tsawg dua lossis sib npaug rau 0.10 acetaldehyde Tsawg dua lossis sib npaug rau 0.05 acrolein Tsawg dua lossis sib npaug rau 0.05
Thib ob, tom qab kev ntsuas kub ntawm cov khoom siv tsheb
Cov khoom siv ntsia tom qab lub tsheb muaj ntau qhov ua tau raws li tus kheej nyiam nyiam thiab kev teeb tsa lub tsheb, cov ko taw pads, lub rooj zaum npog, lub log npog, lub tsheb naj hoom, dashcam, pendant kho kom zoo nkauj, thiab lwm yam. Cov khoom siv ntau hom, ntau qhov chaw uas cuam tshuam rau VOC. hauv lub tsheb.
Lub sijhawm no peb xaiv lub xov tooj ntawm tes sawv ntsug, dashcam, lub tsheb naj hoom, lub kauj log npog raws li cov khoom siv yooj yim rau kev xeem.
Test txheej txheem:
Nws tuaj yeem pom tau tias lub thawv ntsuas peb xaiv yog ib lub thawv yas, thiab lub thawv yas tsuas yog 100L, yog li cov ntsiab lus formaldehyde tau txais thaum lub sijhawm kuaj yuav siab dua li qhov xav tau hauv lub tsheb. Lub hom phiaj ntawm qhov kev sim no yog los sib piv qhov kev tso tawm ntawm VOC los ntawm cov khoom siv tsheb sib txawv, thiab cov txiaj ntsig kev xeem zaum kawg tsis tuaj yeem siv raws li lawv tso VOC hauv lub tsheb.
Vim tias cov txheej txheem kuaj yuav tsum tau ua kom sov, peb ntsuas cov ntsiab lus formaldehyde hauv lub tank khoob ntawm chav tsev kub ntawm 25 degree ua ntej kev xeem, thiab cov ntsiab lus formaldehyde hauv lub tank khoob tom qab cua sov mus rau 60 degree.
Cov ntsiab lus formaldehyde ntawm lub thawv khoob yog 0.121 mg/m³, uas dhau ntawm formaldehyde cov ntsiab lus hauv lub tsheb. Yog li, qhov kev sim no tsuas yog siv los ua ib qho kev siv rau VOC tso tawm ntawm cov khoom siv tsheb.
Tom qab qhov ntsuas kub hauv lub thawv khoob yog rhuab mus rau 60 degree rau ib nrab ib teev, cov ntsiab lus formaldehyde hauv lub thawv khoob yog 0.128mg / m³.
