Catalyst carrier cordierite honeycomb ceramics rau DOC
Catalytic converter substrate rau tsheb:
nws cov khoom tseem ceeb yog tsim los ntawm cordierite thiab stainless hlau ntawm hlau
Cov khoom siv rau catalytic converter substrate yog cordierite. Lub ntuj cordierite muaj tsawg heev nyob rau hauv qhov, yog li feem ntau ntawm
cordieriites yog cov khoom tsim los ntawm tib neeg. Cov yam ntxwv tseem ceeb rau xws li cordierite yog thermal expansion coefficient, zoo thermal
poob siab tsis kam, siab anti-acid, anti-alkali thiab antii-erosion muaj nuj nqi thiab zoo txhua yam muaj zog.
CPSI li niaj zaus rau catalytic converter substrate yog 400. Cov duab ntawm honeycomb ceramic yog puag ncig, racetrack, ellipse thiab lwm yam
tshwj xeeb cov duab raws li tus neeg yuav tsum tau muaj nyob rau hauv thiaj li yuav ua tau raws li lub tsheb sib txawv qauv yuav tsum tau.
