I-substrate yekhekheba lezinyosi iyisakhiwo sekhekheba lezinyosi esiyingqayizivele esihlanganisa iziteshi eziningi ezinezindonga ezincane ezakha iphethini yegridi enezinhlangothi ezine.Lezi ziteshi ngokuvamile zenziwe ngezitsha zobumba, ezifana ne-cordierite noma i-alumina, ekhethelwe izici zayo ezinhle kakhulu ezishisayo nezamamishini.Ama-substrates e-Ceramic honeycomb aziwa ngokuqina kwawo okuphezulu kanye nokwehla kwengcindezi ephansi, okuwenza alungele ukusetshenziswa okuhlukahlukene okudinga ukugeleza komoya okusebenzayo.

Thuthukisa ukusebenza kwe-catalyst:

Le substrate ekhethekile ingasetshenziswa njengesistimu yokusekela ama-catalyst futhi inezinzuzo eziningi ngaphezu kwezinto zokwesekwa kwe-catalyst yendabuko.Ngenxa yesakhiwo sayo sekhekheba lezinyosi, inikeza indawo enkulu yokubeka i-catalyst.Ngakho-ke, izinto ezengeziwe ze-catalyst zingasatshalaliswa ngokulinganayo, ngaleyo ndlela kuthuthukiswe umsebenzi we-catalytic nokusebenza kahle.Ukwengeza, izici zokwehla kwengcindezi ephansi ye-ceramic honeycomb substrate ziqinisekisa ukugeleza komoya okuhle, ngaleyo ndlela kunciphisa ukusetshenziswa kwamandla.

Ibanga elibanzi lezinhlelo zokusebenza:

I-Ceramic honeycomb substrates inezicelo ezimbonini ezihlukahlukene ezithembele kuma-catalysts.Kuziguquli ze-catalytic zezimoto, lawa ma-substrates angakwazi ukuguqula ngempumelelo amagesi kagesi ayingozi abe ukukhishwa okunobuthi obuncane, ngaleyo ndlela ehlise ukungcoliswa komoya.Abuye asetshenziswe kabanzi ezinhlelweni zokulawula ukungcola kwezimboni ezifana nezinjini zegesi ukuze zisuse izinto ezingcolisayo futhi zihambisane nezindinganiso eziqinile zemvelo.

Ngaphezu kwalokho, ama-substrates e-ceramic honeycomb adlala indima ebalulekile ekukhiqizeni i-hydrogen namaseli kaphethiloli, okwenza kube lula ukuguqulwa kwamandla avuselelekayo abe ugesi osebenzisekayo.Ukuqina kwayo nokumelana nokushisa okuphezulu kuyenza ilungele izimo zokusebenza ezinzima, iqinisekisa ukusebenza okuhlala isikhathi eside, okuthembekile.

Izinzuzo Zemvelo:

Ukwamukelwa kwe-ceramic honeycomb substrates kuletha izinzuzo ezinkulu zemvelo.Amandla alawa ma-substrates okuthuthukisa umsebenzi we-catalytic angavumela ukulayishwa kwe-catalyst okuphansi futhi ngaleyo ndlela kusetshenziswe jikelele izinsimbi ezisezingeni eliphezulu njengeplatinum ne-palladium.Ngakho-ke lokhu kunciphisa umthelela wemvelo ohambisana nezimayini kanye nokucwengwa kwalezi zinsiza ezibizayo.

Ukwengeza, ukuguqulwa okusebenzayo kokukhipha izinto eziyingozi ngokusebenzisa amakhekheba oju e-ceramic kungasiza ekunciphiseni ukungcoliswa komoya futhi kube nomthelela endaweni ehlanzekile, enempilo.Ukwehliswa kokusetshenziswa kwamandla okulethwa ukwehla komfutho ophansi nakho kuhumusha ekuncipheni kokukhishwa kwekhabhoni, ukukhuthaza intuthuko esimeme kanye nokulwa nokushintsha kwesimo sezulu.

Ngokufigqiwe:

Emkhakheni wezinhlelo zokusekela i-catalyst, ama-substrates e-ceramic honeycomb afakazele ukuthi angabashintshi bangempela begeyimu.Isakhiwo sayo se-porous esiyingqayizivele, i-porosity ephezulu kanye nokwehla kwengcindezi ephansi kuyenza ibe yinto enhle kakhulu yokusekela i-catalyst.Ngokuthuthukisa umsebenzi we-catalytic, ukunciphisa ukusetshenziswa kwamandla kanye nokuhlinzeka ngezinzuzo zemvelo, i-ceramic substrates ye-honeycomb iletha amathuba amasha ezimbonini ezihlose ukuthuthukisa ukusebenza kahle nokusimama.Njengoba ubuchwepheshe buqhubeka buthuthuka, singalindela kuphela okunye okusha kanye nokusetshenziswa kwale substrate ephawulekayo ezinqubweni ze-catalytic, okuvula indlela yekusasa eliqhakazile, neliluhlaza.
