Catalyst carrier cordierite honeycomb ceramics for DOC Featured Image

Alaab -qeybiye side dhoobada dhoobada malabka malabka ee DOC

Sharaxaad Gaaban:

Substrate -ka malabka dhoobada ah (monolith catalyst) waa nooc cusub oo wax soosaarka dhoobada warshadaha ah, sida side wax kiciya oo si weyn loogu isticmaalo nidaamka nadiifinta qiiqa baabuurta iyo nidaamka daaweynta gaaska qiiqa warshadaha.

Faahfaahinta Alaabta

Calaamadaha alaabta

Substrate -ka beddel -ka -beddelka ee baabuurka:

alaabtiisa ugu weyni waxay ka kooban tahay cordierite iyo birta birta ah ee birta
Waxyaabaha loogu talagalay substrate -ka beddel -ka -beddelku waa cordierite. Dabeecadda dabiiciga ahi aad bay u yar tahay dabeecadda, sidaa darteed badankeeda
cordierites waa walax dadku sameeyay. Astaamaha ugu waaweyn ee cordierite -kan ayaa ah isugeyn ballaarinta kuleylka oo hooseeya, kuleyl wanaagsan
iska caabbinta naxdinta leh, aashitada sare, anti-alkali iyo shaqo-nabaad-guurka iyo xoog farsamo oo wanaagsan.
CPSI -ga caadiga ah ee substrate converter catalytic waa 400. Qaabka dhoobada malabka waa wareegsan, orodka, ellipse iyo kuwa kale
qaab gaar ah iyadoo loo eegayo baahida macmiilka si loo buuxiyo shuruudaha moodooyinka baabuurta ee kala duwan.
