Peb txhua tus paub tias peb tsis tuaj yeem txav mus rau hauv tam sim ntawd tom qab kho kom zoo nkauj ntawm lub tsev tshiab, vim tias cov ntsiab lus ntawm formaldehyde nyob rau hauv chav tsev yog qhov siab heev nyob rau lub sijhawm no. Peb yuav tsum paub txog kev tsim txom ntawm formaldehyde, uas ua rau muaj kev phom sij rau tib neeg lub cev. Rau qee cov phooj ywg uas xav txav mus rau hauv lub tsev tshiab sai li sai tau, nws yog qhov ceev kom tshem tawm cov formaldehyde sab hauv tsev, yog li ntau tsev neeg yuav siv cov pa roj carbon activated. Cov pa roj carbon activated puas tuaj yeem tshem tawm cov formaldehyde sab hauv? Yuav siv cov activated carbon li cas? Niaj hnub no, cia peb tham txog seb cov pa roj carbon activated puas muaj txiaj ntsig rau kev tshem tawm formaldehyde.
Cov pa roj carbon activated puas tuaj yeem tshem tawm formaldehyde?
Activated carbon yog ib qho amorphous carbon nyob rau hauv daim ntawv ntawm hmoov, granule, thaiv thiab honeycomb. Txawm tias cov pa roj carbon activated tau teem caij tsis tu ncua. Vim nws cov yam ntxwv ruaj khov, nws muaj qhov kub tsis kam, alkali tsis kam, acid tsis kam thiab dej tsis kam. Nws yog dav siv nyob rau hauv niaj hnub tshuaj kev lag luam, kev tiv thaiv ib puag ncig thiab lwm yam teb.
Txawm hais tias feem ntau cov pa roj carbon activated muaj peev xwm nqus tau zoo, yog tias nws tsuas yog nyob ntawm kev nqus kom tshem tawm formaldehyde, nws yuav ncav cuag lub xeev saturation hauv lub sijhawm luv luv. Lub sijhawm no, cov pa roj carbon activated yuav tsis tsuas yog tsis tshem tawm cov formaldehyde, tab sis kuj dhau los ua cov pa phem thiab tso tawm cov formaldehyde absorbed rau sab nraud, uas muaj qhov tsis zoo.
Txawm hais tias cov pa roj carbon activated tuaj yeem tshem tawm formaldehyde, cov nyhuv kuj qeeb thiab cov nyhuv tsis tiav. Thaum lub qub activated carbon siv nyob rau hauv tsev yog siv li 3 lub hlis, nws yuav tsum tau hloov nrog tshiab carbon. Cov nyhuv yuav zoo dua nyob rau lub sijhawm no.
Yuav siv cov activated carbon kom raug li cas?
Dosage ntawm activated carbon:
Cov chav kho kom zoo nkauj tshiab (xws li chaw ua haujlwm, tsev so, thiab lwm yam) yuav tsum tau siv raws li qhov ntau npaum li cas ntawm 1-2 hnab ib square meter (piv txwv li 50-100g). Kev tiv thaiv txhua hnub ntawm ib puag ncig sab hauv tsev tuaj yeem raug txo kom tsim nyog raws li qib ntawm cov pa phem.
Nco tseg: 50-100g ib square meter yog siv los xam tag nrho qhov chaw siv, thiab tsis txhais hais tias 50-100g yog muab tso rau ib tug ib square meter.
Kev siv cov activated carbon:
1. Ua ntej tshaj plaws, peb tshem tawm cov roj carbon activated tom qab kev yuav khoom thiab muab tso rau hauv chav pw, txee, chav kawm, chav nyob, chav dej, chav cia khoom thiab lwm qhov chaw uas yuav tsum tau ua kom huv.
2. Feem ntau hais lus, thaj chaw kho mob ntawm ib lub thawv ntawm cov pa roj carbon activated yog li 120 square meters. Nyob ntawm kev ua qias tuaj, nws raug nquahu kom siv ntau ntxiv thaum muaj kuab paug hnyav. Khaws lub qhov rais qhib thiab qhov cua thaum siv, thiab cov nyhuv zoo dua.
3. Cov pa roj carbon activated feem ntau tsis muaj tshuaj lom thiab muaj kev phiv. Nws raug nquahu kom tso ib lub hnab ntawm 1-1.5 square metres hauv chav tsev kho kom zoo nkauj tshiab.
4. Lub neej tsis tau qhib ntawm cov pa roj carbon activated yog 5 xyoo, thiab lub sijhawm siv tau tom qab kev sib khi yog 3 xyoos. Ua tib zoo saib xyuas lub neej ua haujlwm.
5. Tom qab 30 hnub ntawm kev siv, cov pa roj carbon activated tuaj yeem decompose cov khoom tsis zoo tom qab raug tshav ntuj rau 3-5 teev, thiab nws cov txiaj ntsig rov ua dua tseem ceeb heev.
Puas yog cov pa roj carbon activated tuaj yeem tawm ntawm cov pa roj carbon activated tom qab adsorbing cov pa phem thiab cov pa phem?
Cov txheej txheem uas cov molecules ntawm adsorbed lom thiab teeb meem gases raug tso tawm los ntawm micropores ntawm activated carbon yog hu ua "desorption" ntawm activated carbon los yog "regeneration" ntawm activated carbon. Lub "desorption" ntawm cov pa roj carbon activated yuav tsum ua kom tiav hauv cov cuab yeej tshwj xeeb los ntawm cov txheej txheem nyuaj xws li thermal regeneration, tshuaj elution, hnyav extraction regeneration thiab lom regeneration. Yog li ntawd, nyob rau hauv ib puag ncig ntuj, cov tshuaj lom thiab teeb meem roj molecules adsorbed nyob rau hauv lub micropores ntawm activated carbon tsis tuaj yeem tawm ntawm lawv tus kheej.
