Catalyst carrier cordierite honeycomb iiseramics for DOC

Inkcazelo emfutshane:

I-substrate ye-Ceramic honeycomb (i-catalyst monolith) luhlobo olutsha lwemveliso ye-ceramic yoshishino, njenge-catalyst carrier esetyenziswa ngokubanzi kwinkqubo yokucoca i-automobile emissions system kunye ne-industrial exhaust gas treatment system.

Iithegi zeMveliso

I-Catalytic converter substrate yesithuthi:

impahla yayo enkulu yenziwe cordierite kunye nentsimbi stainless yentsimbi
Izinto eziphathekayo ze-catalytic converter substrate yi-cordierite. I-cordierite yendalo inqabile kakhulu kwindalo, ngoko ke uninzi
i-cordierite zizinto ezenziwe ngabantu. Iimpawu eziphambili ze-cordierite i-coefficient ephantsi yokwandisa i-thermal, i-thermal efanelekileyo
ukuxhathisa ukothuka, i-anti-asidi ephezulu, i-anti-alkali kunye ne-antii-rosion function kunye namandla amahle omatshini.
I-CPSI eqhelekileyo ye-catalytic converter substrate yi-400. Imilo ye-honeycomb iceramic ingqukuva, i-racetrack, iellipse kunye nezinye.
imilo ekhethekileyo ngokwemfuno yomthengi ukuze kuhlangatyezwane neemfuno zeemodeli zeemoto ezahlukeneyo.
