Cov pa roj carbon activated yog ib hom dub ntxeem tau cov pa roj carbon monoxide, uas yog tsim los ntawm pulverizing, sib sau los yog carbonizing thiab activating thee nrog uniform coal particles. Lub ntsiab tivthaiv yog carbon, thiab muaj me me ntawm oxygen, hydrogen, sulfur, nitrogen, chlorine thiab lwm yam khoom. Qhov chaw tshwj xeeb ntawm cov pa roj carbon activated yog nruab nrab ntawm 500 thiab 1700 m2 / g. Nws muaj zog adsorption kev ua tau zoo thiab yog siv dav siv adsorbent.
Yuav ua li cas ua kom cov pa roj carbon adsorb formaldehyde zoo?Txhawm rau siv qhov cua thiab qhov cua, ntxiv rau stacking activated carbon ntawm qhov chaw ntawm kev tso tawm, nws tseem yuav tsum tau ntsuas nws cov concentration nquag, thiab nws yuav tsum tau hloov nws yog tias pom tias nws saturated. Ib lub ntsiab lus ua ntej. Cov formaldehyde nyob rau hauv lub tsev kho dua tshiab yog cov txheej txheem ntawm kev tso tawm tas li. Qhov no qhia tau hais tias kev tswj ntawm formaldehyde muaj kuab paug kuj yog ib tug tas mus li txheej txheem.
Qhov twg formaldehyde hauv tsev kho kom zoo nkauj tsuas yog los ntawm?Ib feem loj ntawm nws yog los ntawm pheej yig cov kua nplaum nyob rau hauv cov khoom vaj khoom tsev - urea formaldehyde resin (tsuas yog nws tsis yog cov ntoo nyoos, nws tuaj yeem suav tau tias yog cov khoom siv hluav taws xob, cov khoom siv hauv pem teb,) Tsis tas li ntawd, gypsum board, xim, yas. cov khoom, cov nplaum kuj muaj nyob rau hauv Nws muaj peev xwm hais tias nws muaj formaldehyde, tsuas yog hais tias nws yog tsawg dua piv rau tus nqi ntawm cov khoom vaj khoom tsev. Yog li ntawd, activated carbon yuav tsum tau muab tso rau lub sij hawm ntev thiab adsorbed rau ib tug ntev lub sij hawm nyob rau hauv thiaj li yuav muaj zoo purification tshwm sim.
