Caij nplooj ntoos hlav txaj uas muaj formaldehyde loj ntawm ib yam khoom! Saib ntawm nws lub tsev lub caij nplooj ntoos hlav txaj nyob ntawd!

Cov cuab yeej ntawm lub caij nplooj ntoos hlav txaj yog peb mus pw txhua hmo. Puag saum txaj pw, tej zaum peb yuav tsis xav tias, thaum peb nyob rau lub caij nplooj ntoos hlav lub txaj, qhov tseeb muaj cov pa phem hnyav, tuaj yeem ua rau peb noj qab haus huv, uas yog formaldehyde. Lub caij nplooj ntoos hlav txaj yog formaldehyde muaj kuab paug, qhov chaw tseem ceeb yog qhwv rau hauv nws txheej txheej ntawm cov yas. Feem ntau, cov pa phem yas yuav loj dua. Thiab cov txheej no ntawm cov yas qhwv lub caij nplooj ntoos hlav txaj, vim tias nws tsis yog, yog li cov tuam ntxhab yuav tsis siv cov khoom zoo, feem ntau yog cov neeg pluag heev, nws ua rau nws cov formaldehyde muaj kuab paug hnyav heev. Formaldehyde kuab paug peb tsis paub, txhua tus dai kom zoo nkauj hauv tsev paub tias nws tsis tsuas yog qias neeg, thiab nyuaj rau tswj, yuav cuam tshuam rau peb lub cev. Yog li ntawd, thaum siv lub caij nplooj ntoos hlav txaj, saum txheej ntawm cov yas yuav tsum tau muab tshem tawm. Los yog peb mus pw txhua hmo nyob rau saum toj no, yuav ua rau peb noj qab haus huv. Feem ntau, peb yuav muaj ntau formaldehyde paug nyob rau hauv tsev, tsis yog tsuas yog lub caij nplooj ntoos hlav txaj txaj, yog li ntawm no kuj yog thiab koj hais ob peb ntxiv rau formaldehyde txoj kev: dilute formaldehyde: qhov cua formaldehyde tso tawm yuav pawg nyob rau hauv ib chav tsev nyob rau hauv lub tsev, ntev ntev yuav rog. Qhov cua yog lub tsev ntawm lub qhov rais, qhib lub qhov rooj, cia cua ntws mus rau hauv chav tsev, dilute cov tsub zuj zuj ntawm formaldehyde, formaldehyde concentrations txo ib co. Tab sis tsis txhob hnov ​​qab tias qhov cua tuaj yeem tswj tau formaldehyde, tsuav yog peb tsis tau qhib lub qhov rais, formaldehyde tshaj qhov kev sib tw yuav rov siv dua, peb tsis tuaj yeem qhib lub qhov rais ntev. Yog li yuav tsum tau siv lwm txoj kev tshem tawm formaldehyde. Adsorption formaldehyde: qhov porosity ntawm cov pa roj carbon activated carbon yog ntau dua, yog tias thaum raug huab cua, huab cua mus rau formaldehyde adsorption. Tab sis muab tso rau lawv lub peev xwm yog txwv, ntau active carbon adsorption rau ib lub sij hawm ntawm lub sij hawm yuav tag nrho saturation. Lub sijhawm no yog qhov txaus ntshai heev, yog tias tsis hloov raws sijhawm tuaj yeem ua rau formaldehyde rebound, cov pa phem thib ob. Yog li kev siv cov pa roj carbon activated yuav tsum tau hloov txhua 25 hnub los yog li ntawd. Lub decomposition ntawm formaldehyde: katyn Shi Luoting pob zeb yog ib yam khoom uas yuav decomposed ntawm formaldehyde. Txawm tias diluted los yog formaldehyde adsorption, formaldehyde tuaj yeem tshem tawm tag nrho cov formaldehyde, thiab los katyn pob zeb tom qab adsorption ntawm formaldehyde, formaldehyde absorption rau sab hauv tawg. Nws yog nyob ntawm kev tswj kom zoo ntawm formaldehyde, tuaj yeem khaws cov huab cua hauv tsev. Vim hais tias decomposition tsis saturated, lub sij hawm siv los katyn pob zeb feem ntau yog ntau tshaj 3 xyoo. Dissolve formaldehyde: Txawm hais tias dej yog ib hom tuaj yeem yaj formaldehyde, tab sis txoj kev no tsis yooj yim rau siv. Vim hais tias peb nyob rau hauv ib chav tsev yuav muab ib lub phiab yog txwv, thiab lub phiab thiab piv nrog formaldehyde pa phem nyob rau hauv lub tsev ua ke, kuj yog tsis heev txaus, tsis muaj zog heev. Kuj yuav tsum tau saib xyuas, cov dej hauv chav tsis tuaj yeem muab tso rau ntev, nws yooj yim rau worm
