Chikhomo cha uchi cha ceramic

Cordierite wakupangika na magnesium -alumino-silicate chinthu cha ceramic, pafupifupi vyose vya mazuŵa ghano vyakupangika na ceramic vyakupangika na cordierite.
honeHoneycomb mic substrate catalyst vigaŵa vyakupangika mu nthowa yakufumiskiramo, vinthu vyambura kupangika nga ni alumina, talc, dongo (kaolinite), na silica vikuchepeskeka kuŵa ufu na kusakanizgika mu maji -kupangika na phala. Vinthu ivyo vingaŵikika mu ndondomeko iyi ni mafuta ghakupangira thupi (mwachiyelezgero, ethylene glycol), vyakupangiska kuti vinthu viŵe vyakukolerana (mwachiyelezgero, methylcellulose), na vinthu vyakuthukira (mwachiyelezgero, mafuta gha alkaline). Vinthu ivyo vikupangika na phala ivi vikuwumiskika, kudumulika kufika pa utali, na kuviŵika pa moto uwo ukujumpha madigiri 1400 .

Vithuzithuzi vya chikho cha uchi cha ceramic

Vinthu vyakupangika na ceramic vya chikho cha uchi vikugwiriskirika nchito mu vipangizo vyakusintha vinthu ivyo vikupangika na mtundu wapadera wa vinthu vyakupangika na ceramic ivyo vikuchemeka kuti ‘cordierite’. Ŵakufumiska maji gha cordierite mu nkhungu ndipo pamanyuma ŵakughawotcha mwakuti ghaume na kukhoma. Pakugwiriskira ncito nkhungu zakupambanapambana, vigaŵa vyakupambanapambana vya kukura vingafumiskika ndiposo kukura kwa nthowa (panji maselo) nako kungaŵa kwakupambanapambana. Chifukwa chakuti viŵiya vikukhumbikwa, viŵiya vya uchi vya ceramic vikuyana chomene na ivyo vikukhumbikwa pa voliyumu ya pakatikati panji yikuru kupatulapo para mungagwiliskira ntchito saizi yakumanyikwa. Vikhomo vya uchi vya ceramic kanandi ndivyo vikupangiska kuti ŵanthu ŵasange ndalama zinandi nga ni masitovu gha biomass na mavuni ghakutozga gha pyrolytic self-.
Kukura kwa maselo nchinthu cakuzirwa comene ico cikovwira kuti catalytic converter yigwirenge nchito makora. Kweni m’malo mwa kuyowoya mwakudunjika pa kukura kwa maselo, nchakwenelera kuti munthu wamanye unandi wa maselo agho ghalipo pa unit ya malo, mwachiyelezgero maselo pa square inch (cpsi) panji maselo pa square centimeter.
Substrates kusintha pachoko kukura kwawo pa nyengo ya calcination, vigaŵa vya kukula kwakuchepa vingapangika mu ndondomeko yimoza-sitepe kwizira mu kuyowoyerathu kuti kusintha na kufumiska vigaŵa ku vigaŵa ivyo vikupambanako pachoko na ivyo vikuyowoyeka pa chinthu chakumalizgika, vigaŵa vikuru vya diameter, ku mbali yinyake, vingakhumbikwira multi{truction and {1,de ex}ste the vigaŵa vikuruvikuru, ndipo pamanyuma pake ŵakuvipanga kuti vikolerane na ivyo vikukhumbikwa, vikudumulika kufika pa utali waumaliro, vikupangika na makina, chikumba cha kuwaro chikuŵikika mwakugwiliskira ntchito phala la ceramic, ndipo vigaŵa ivi vikuwumiskika mu uvuni-.
Ceramic monoliths uchi wakusangika mawonekero: makona ghatatu, silinda panji ellipse, mawonekero gha maselo mu square, mzere, hexagonal, triangle etc. likung’anamura maselo pa square inch).
Ceramic Honeycomb Substrate iyo yikugwiriskirika nchito mu vipangizo vyakupangiska kuti vinthu viŵeko yikuŵa na nkhongono yakusazgirako kutentha, malo ghapachanya ghakumanyikwa, kugwa kwakuchepa kwa nkhongono, ungweru wa luwiro-kuzima na vigaŵa vyapadera. Maselo masauzandi ghanandi ghakupereka malo ghapachanya gha vipangizo vya vitsulo vyakuzirwa ivyo vikusintha mphepo zakupweteka kuŵa nthunzi ya maji, carbon dioxide na vinyake, viŵiya vyakupangika na chikho cha uchi vikukanizga mawonekero agho ghalipo: makona ghatatu, silinda panji ellipse. Mawonekero gha maselo mu bwalo, bwalo, makona 6, makona ghatatu na vinyake.
Catalyst substrate ni chigaŵa chakuzirwa chomene icho chikukhwaska ntchito, nkhongono, na kukhalilira kwa ndondomeko zakusintha kwa catalytic, ceramic honeycomb substrate iyo yikugwiriskirika nchito mu catalytic converters yili na coefficient yakusazgikira ya kutentha kwakucepa comene, malo ghapachanya ghakumanyikwa, kugwa kwakucepa kwa nkhongono, ungweru wa luwiro vipangizo ivyo vikusintha mphepo zakupweteka kuŵa nthunzi ya maji, carbon dioxide na vinyake, vigaŵa vyakupangika vya ceramic catalyst substrates vikusazgapo ivi:
