Ekintu ekiyitibwa Ceramic Substrate eky’omubisi gw’enjuki

Cordierite ey’obutonde ye magnesium-alumino-silicate ceramic material, kumpi byonna eby’ennaku zino eby’omubisi gw’enjuki ceramic substrate catalyst substrates bikoleddwa mu cordierite.
honeHoneycomb mic substrate catalyst substrates zikolebwa mu nkola ya extrusion, ebigimusa nga alumina, talc, ebbumba (kaolinite), ne silica bikendeezebwa ne bifuuka butto ne bitabulwa mu paste ekoleddwa mu mazzi-. Ebirungo ebiyinza okugattibwa mu nkola eno mulimu ebizigo (okugeza ethylene glycol), ebikwatagana (okugeza methylcellulose), n’ebifuumuuka (alkaline hydroxides). Ebintu ebifulumizibwa mu kikuta kino bikalizibwa, ne bisalibwa okutuuka ku buwanvu, ne biyokebwa ku bbugumu erisukka diguli 1400 .

Ebifaananyi bya ceramic honeycomb substrate

Honeycomb ceramic substrates zikozesebwa mu catalytic converters mu budde obutuufu zikolebwa okuva mu kika eky’enjawulo eky’ekintu kya ceramic ekimanyiddwa nga ‘cordierite’. Cordierite ow’amazzi afulumizibwa okuyita mu kibumba n’oluvannyuma n’ekubwa omuliro ne gukala ne gukaluba. Nga tukozesa ebibumbe eby’enjawulo, ebisengejja eby’obunene obw’enjawulo bisobola okufulumizibwa era obunene bw’emikutu (oba obutoffaali) nabwo busobola okukyusibwakyusibwa. Olw’okuba ebikozesebwa byetaagibwa, ebikuta by’enjuki ebya seramiki bisinga kukwatagana na byetaago bya voliyumu eya wakati oba ennene okuggyako nga sayizi eya mutindo esobola okukozesebwa. Okutwalira awamu ebikuta by’enjuki ebya keramiki bye bisinga okukekkereza ku byuma ebikozesebwa nga sitoovu ezikola ebiramu n’oveni ez’okweyonja eziyitibwa pyrolytic self-.
Enkula y’obutoffaali nkyukakyuka nkulu eyamba mu kukola kw’ekikyusa ekirungo ekiziyiza (catalytic converter). Naye mu kifo ky’okujuliza butereevu obunene bw’obutoffaali, kya bulijjo okugera obungi bw’obutoffaali obuliwo buli yuniti y’obuwanvu, okugeza obutoffaali buli square inch (cpsi) oba obutoffaali buli square centimeter.
Substrates zikyusa katono ebipimo byazo mu kiseera ky’okukkirizibwa, ebitundu eby’obunene obutono bisobola okukolebwa mu nkola ya mutendera gumu-nga biyita mu kuteebereza nti okukyusa n’okufulumya ebitundu ku bipimo ebyawukana katono ku specifications of finished product, larger diameter parts, ku ludda olulala, biyinza okwetaaga multi-step production process, the substrates are extruded and calcined to larger dimensions, okugobererwa okulongoosa okutuukana n’ebipimo byabwe, zisalibwa okutuuka ku buwanvu obusembayo, enkula zazo zikolebwa mu kyuma, olususu olw’ebweru lusiigibwa nga bakozesa ekikuta kya seramiki, era ebitundu ne bikalizibwa mu oven-.
Ceramic honeycomb monoliths available shapes: rectangular, cylinder oba ellipse, cell shapes mu square, circle, hexagonal, triangle etc. tusobola n’okulongoosa okufulumya okusinziira ku kifaananyi kyo ne sampuli, ceramic honeycomb ne cell structure density okuva ku 10 okutuuka ku 300cpsi/ 400cpsi/ 600cpsi (CPSI kitegeeza obutoffaali buli square inch).
Ceramic Honeycomb Substrate ekozesebwa mu catalytic converters erina omugerageranyo gw’okugaziwa kw’ebbugumu omutono ennyo, ekitundu ekinene eky’okungulu ekigere, okugwa kwa puleesa okutono, ekitangaala-okuzikira amangu n’ensengekera ez’enjawulo. Enkumi n’enkumi z’obutoffaali buwa ekifo eky’okungulu eri ebiziyiza ebyuma eby’omuwendo ebikyusa okufuluma okw’obulabe okufuuka omukka gw’amazzi, kaboni dayokisayidi n’ebirala, seramiki z’omubisi gw’enjuki ziziyiza enkula eziriwo: enjuyi ennya, silinda oba ellipse. Enkula z’obutoffaali mu square, circle, hexagonal, triangle n’ebirala.
Catalyst substrate kitundu kikulu nnyo ekikwata ku nkola, obugumu, n’obuwangaazi bw’enkola za catalytic converter, ceramic honeycomb substrate ekozesebwa mu catalytic converters erina omugerageranyo gw’okugaziwa kw’ebbugumu omutono ennyo, ekitundu ekinene eky’okungulu ekigere, okugwa kwa puleesa entono, ekitangaala eky’amangu-okuzikira n’ensengekera ez’enjawulo, enkumi n’enkumi z’obutoffaali buwa surface eya waggulu eri catalysts z’ebyuma eby’omuwendo ezikyusa emission etali ya muwendo mu vapor y’amazzi, carbon dayokisayidi n’ebirala, ebigendererwa by’okukola dizayini y’ebintu ebikozesebwa mu kukola ebirungo bya seramiki mulimu bino wammanga:
