Mpweya wokhazikika, womwe nthawi zina umatchedwa activated charcoal, ndi chinthu chapadera chomwe chimayamikiridwa chifukwa cha mawonekedwe ake obowola kwambiri omwe amalola kuti agwire bwino ndikusunga zida.
Amagwiritsidwa ntchito kwambiri m'mafakitale angapo kuti achotse zinthu zosafunikira ku zakumwa kapena mpweya, kaboni woyamwa angagwiritsidwe ntchito kuzinthu zingapo zosatha zomwe zimafuna kuchotsa zonyansa kapena zinthu zosafunikira, kuyeretsa madzi ndi mpweya, kukonza nthaka, ngakhale golide. kuchira.
Pano pali chithunzithunzi cha zinthu izi modabwitsa zosiyanasiyana.
KODI CARBON YOPHUNZITSIDWA NDI CHIYANI?
Activated carbon ndi zinthu zochokera ku kaboni zomwe zasinthidwa kuti ziwonjezere mphamvu zake zokopa, kutulutsa chinthu chapamwamba cha adsorbent.
Mpweya wokhala ndi activated umakhala ndi pore yochititsa chidwi yomwe imapangitsa kuti ikhale ndi malo okwera kwambiri pomwe ingagwire ndikusunga zinthu, ndipo imatha kupangidwa kuchokera kuzinthu zingapo zokhala ndi kaboni, kuphatikiza:
Zipolopolo za kokonati
Wood
Malasha
Peat
Ndipo zambiri…
Kutengera ndi komwe kumachokera, komanso njira zopangira zomwe zimagwiritsidwa ntchito popanga kaboni, mawonekedwe ake ndi mankhwala a chinthu chomaliza amatha kukhala osiyana kwambiri. Pachifukwa ichi, ma carbon opangidwa ndi malonda ndi apadera kwambiri kuti apeze zotsatira zabwino pa ntchito yomwe yaperekedwa.
Ngakhale kusiyanasiyana kotereku, pali mitundu itatu yayikulu ya carbon activated:
Mpweya Activated Carbon (PAC)
Mpweya wa carbon activated nthawi zambiri umagwera mu kukula kwa tinthu 5 mpaka 150 Å, ndi makulidwe ena akunja. PAC's nthawi zambiri amagwiritsidwa ntchito pamadzi-gawo adsorption ntchito ndipo amapereka kutsika mtengo processing ndi kusinthasintha ntchito.
Granular Activated Carbon (GAC)
Granular adamulowetsa mpweya zambiri amakhala tinthu kukula 0.2 mm kuti 5 mm ndipo angagwiritsidwe ntchito onse gasi ndi madzi gawo ntchito. Ma GAC ndi otchuka chifukwa amapereka kusamalira koyera ndipo amakhala nthawi yayitali kuposa ma PAC.
Kuonjezera apo, amapereka mphamvu zowonjezera (kuuma) ndipo akhoza kusinthidwa ndikugwiritsidwanso ntchito.
Mpweya Wowonjezera Wowonjezera (EAC)
Ma carbon activated ndi cylindrical pellet product kuyambira 1 mm mpaka 5 mm. Nthawi zambiri amagwiritsidwa ntchito pakuchita gasi, ma EAC ndi kaboni wolemetsa chifukwa cha njira yotulutsira.
Mitundu Yowonjezera
Mitundu yowonjezera ya carbon activated ndi:
Bead Activated Carbon
Mpweya wa Mpweya
Mpweya Wopaka Polima
Zovala za Carbon Zoyambitsa
Ma Fiber A Carbon Oyambitsa
ZINTHU ZA CARBON YOPHUNZITSIDWA
Posankha kaboni woyamwa kuti agwiritse ntchito, mitundu yosiyanasiyana iyenera kuganiziridwa:
Kapangidwe ka Pore
Kapangidwe ka mbombo ka carbon activated zimasiyanasiyana ndipo makamaka chifukwa cha gwero ndi njira yopangira.¹ Kapangidwe ka bore, kuphatikiza ndi mphamvu zokopa, ndizomwe zimalola kuti kudsorption kuchitike.
Kuuma / Kutupa
Kuuma / kuyabwa ndi chinthu chofunikira pakusankha. Ntchito zambiri zimafuna kuti mpweya woyamwa ukhale ndi mphamvu ya tinthu tambirimbiri komanso kukana kutsika (kuwonongeka kwa zinthu kukhala chindapusa). Mpweya wopangidwa kuchokera ku zipolopolo za kokonati uli ndi kuuma kwambiri kwa carbon activated.4
Ma Adsorptive Properties
Mayamwidwe a carbon activated ali ndi makhalidwe angapo, kuphatikizapo mphamvu ya adsorptive, mlingo wa adsorption, ndi mphamvu yonse ya activated carbon.4
Kutengera ndi ntchito (zamadzimadzi kapena gasi), zinthuzi zitha kuwonetsedwa ndi zinthu zingapo, kuphatikiza nambala ya ayodini, malo, ndi Carbon Tetrachloride Activity (CTC).4
Kachulukidwe Wooneka
Ngakhale kachulukidwe kowoneka bwino sikungakhudze adsorption pa kulemera kwa unit, zidzakhudza adsorption pa unit volume.4
Chinyezi
Moyenera, kuchuluka kwa chinyezi chomwe chili mkati mwa kaboni woyatsidwa kuyenera kugwera mkati mwa 3-6%.4
Phulusa Zokhutira
Phulusa la carbon activated ndi muyeso wa inert, amorphous, inorganic, and unfortable part of the material. Phulusa lidzakhala lotsika momwe zingathere, monga momwe mpweya wotsekemera umachulukira pamene phulusa likuchepa. 4
