Kaw cov laug cam (xws li tuab cov laug cam) muaj cov formaldehyde. Lub ntsiab yog vim li cas yog formaldehyde-muaj cov nplaum, xws li urea-formaldehyde cob, yog siv nyob rau hauv lawv cov txheej txheem ntau lawm. Cov hauv qab no yog qhov kev tshawb fawb tshwj xeeb:
Qhov chaw ntawm formaldehyde
Cov cim ntom ntom yog ua los ntawm cov khoom siv fiber ntau thiab cov kua nplaum los ntawm cua sov thiab nias thiab cov kua nplaum feem ntau muaj formaldehyde. Qhov ntau dua qhov ntau ntawm cov kua nplaum siv, lub siab dua cov ntsiab lus formaldehyde.
Formaldehyde tso tawm voj voog
Tus formaldehyde tso lub voj voog ntawm cov rooj zaum tuab ntev dua, thiab feem ntau yuav siv sijhawm ntau tshaj 3 xyoos rau kev nthuav dav. Qhov no yog vim formaldehyde muaj nyob hauv pawg tswj hwm thiab tso tawm qeeb.
Formaldehyde qib theem
Raws li cov qauv hauv lub teb chaws, cov cim ntom ntom yog muab faib ua e {{0, E1 cov qib kawm raws cov ntsiab lus Formaldehyde:
E {{{{{0}}}}}}}}}}}}} illSyde tso tawm tsawg dua lossis sib npaug rau 0.5mg / l
E1 Qib: formaldehyde tso tsawg dua lossis sib npaug rau 1.5mg / l
E2 Qib: formaldehyde tso tsawg dua lossis sib npaug rau 5mg / l.
Yuav ua li cas txo cov kev puas tsuaj ntawm formaldehyde
Qhov cua: Qhib lub qhov rai rau qhov cua rau 2-3 lub hlis tom qab kev hloov pauv ntawm formaldehyde.
Ua kom cov roj carbon adsorption: Haum rau kev kaw cov chaw xws li pawg ntseeg, tub rau khoom, thiab lwm yam.
Kev kho mob: Koj tuaj yeem nug cov tuam txhab tshaj lij los tuav nws thiab tshem tawm cov formaldehyde.
Cov ntsiab lus: Cov laug cam muaj formaldehyde, tab sis nws cov kev ua mob tuaj yeem txo qis ntawm cov khoom lag luam uas muaj cov kev ntsuas qis dua.
