Ua kom cov pa roj carbon ua haujlwm yog cov khoom siv ntxeem tau nrog cov tshuaj pleev xim thiab cov acchipic, ua raws los ntawm kev ua kom cov pa roj carbon monoxide qis, ua raws li cov pa roj carbon nyob rau hauv nruab nrab roj. Cov hmoov hmoov thaj chaw ntawm cov pa roj carbon ua kom zoo li 500/500m2, thiab nws muaj kev kawm adsorption zoo heev. Lub luag haujlwm tseem ceeb ntawm kev ua cov kev daws teeb meem electroplating yog kom tshem tawm cov roj, cov khoom lag luam organic, thiab cov khoom noj muaj txiaj ntsig ntawm ntau yam kev sib ntxiv.
Thaum siv cov pa roj carbon kom purify plating daws, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
1. Xaiv cov khoom lag luam uas haum rau cov roj carbon. Muaj ob hom carbon ua haujlwm muaj nyob rau ntawm kev ua lag luam: granular thiab hmoov. Granular tshuab txais yog yooj yim dua rau kev lim, tab sis nws cov kev kho mob yog qhov deb dua rau cov tshuaj carbon kom ua huaj yauv. Qhov laj thawj yog qhov tshwj xeeb thaj chaw ntawm cov hmoov ua haujlwm rau cov pa roj carbon ntau ntau dua li cov roj carbon granular. Thaum siv nws, cov kev xaiv yuav tsum yog raws cov qib ntawm kev sib kis ntawm cov kev daws teeb meem.
2. Cov pa roj carbon kom tsis txhob muaj cov kabmob ions uas muaj kev phom sij rau cov kev daws teeb meem. Tam sim no, cov ntaub ntawv raw tseem ceeb rau kev tsim cov roj carbon yog ntoo, thee, thiab cov plhaub ntawm cov tawv tawv plhaub xws li coconuts. Kev xyaum tau ua pov thawj tias nyob rau hauv kev lim dej ntawm cov kev hloov pauv plating, ua haujlwm rau cov txiv hmab txiv ntoo ua haujlwm nyuaj yog qhov zoo dua rau cov khoom thee. Tsis zoo ua tau zoo carbon feem ntau muaj impurities xws li zinc thiab tsis haum rau siv. Yog tias ua kom cov pa roj carbon muaj cov zinc immerities tau siv nyob rau hauv kev ua kom huv ntawm Nickel plating daws, nws yuav ua rau muaj cov tshuaj ntxuav paug qias neeg (xws li cov xwm txheej phem tsis yog qhov tsis yooj yim).
3. Qhov ntau npaum li cas yuav tsum muaj txaus. Rau cov kev daws teeb meem plating nrog cov kab mob sib txawv ntawm cov organic, feem ntau yuav tsum tau saws, feem ntau 2- 5 g / l. Yog hais tias tus nqi tsis txaus, cov nyhuv kho yuav ua tsis zoo. Qhov ntau ntawm cov pa roj carbon tau txiav txim siab los ntawm kev sim me me uas siv cov twj tso tsheb hlau luam me me lossis kev tso tsheb hlau luam.
4. Tus θ thiab Ph thiab Ph Phaj kho yuav tsum tsim nyog. Kev daws teeb meem tag nrho muaj cov kev kho kom zoo dua nyob rau hauv cov kev mob ntawm 55-70℃thiab pH ntawm 5-6. Thaum lub sijhawm ua tiav, θ thiab pH yuav tsum nyob ruaj khov.
5. Do kom huv thiab tusyees. Nws raug nquahu kom siv cov pa tawm lim thiab cov cua compressed rau cov sib quaststub muaj zog nplawm. Yog tias phau ntawv stirring yog siv, nws yuav tsum tau nqa tawm tsis tu ncua thoob plaws hauv lub plating tank tsis muaj kev tuag ib txoj kev tuag. Nws feem ntau yuav siv 2-4 teev.
6. So sijhawm. Tom qab cov txheej txheem adsorption ua tiav, cov kev cog kev cai yuav tsum yog sab laug kom sawv ntsug ib ntus ua ntej feeb, nrog lub sijhawm sawv ntawm 6-12 teev. Tom qab txaus nag lossis daus, kev daws yuav tsum tau lim 2-3 zaug kom txog thaum tsis muaj kev sib cav nrog cov kev daws teeb meem thiab cov xim qub (dub tsis muaj carbon).
7. Tiv thaiv kev tshem tawm. Cov txheej txheem hluav taws xob adops adopts kev ua txuas ntxiv cov kev sib tw ntawm cov pa roj carbon ua haujlwm. Thaum cov pa roj carbon satur activ ad activ activ satur ad satur ad satur satur ad satur satur satur,, cov pa roj carbon in in in hauv lub lim tsheb yuav tsum tau ntxuav kom tiv thaiv kom tsis txhob muaj kev tiv thaiv kom tsis txhob muaj paug.
