Substrate ya Ceramic ni iki?

Ibyuma bya Ceramic byagiye biri mu mutima w’igenzura ry’ibyuka bihumanya ikirere kuva ikoranabuhanga ryatangira mu ntangiriro za 1970 ubwo Corning yavumburaga cordierite y’ubukorikori hamwe n’uburyo bwo gusohora ibinyabiziga bya Ceramic. Ibyuma bya Ceramic byuzuyemo imiyoboro mito ibihumbi, ifunguye ku mpera zose, bigatuma umwotsi w’imodoka unyuramo. Iyi miyoboro itanga ubuso bunini bw’imbere kugira ngo bushyigikire ibikorwa bya catalytic. Iyo substrate ifite ingano ingana n’agacupa ka soda, ubuso bwayo bw’imbere (harimo n’agasanduku ko kumesa gafite ubuso burebure) bufite ubuso bungana n’ikibuga cy’umupira w’amaguru cya Amerika.

Izi substrate zishobora kwihanganira ubushyuhe bwinshi >1100°C (2000°F) kandi zirwanya cyane ubushyuhe (ku buryo zishobora kwihanganira ubushyuhe bwihuse mu gitondo cy'ubukonje). Izi substrate zirahinduka cyane kandi zishobora kwakira ubwoko bwinshi bwa catalyst kugira ngo zikureho umwanda uturuka kuri lisansi, mazutu, gaze karemano, hydrogen n'izindi lisansi.

Igice cyuzuye gitwikiriwe n'ibikoresho bya ngombwa bihinduramo laboratwari nto ya chimie kandi bigatuma ingano nini y'imyuka isohoka itunganywa neza. Mu bushyuhe bwinshi bwa moteri ikora, imyuka isohoka nka azote oxyde na monoxide de carbone ihura na catalyst igahinduka azote n'amazi nta kibazo na dioxyde de carbone idatera ingaruka mbi.

Ibyuma bya mbere bya keramike byari bifite ubucucike buke bw’uturemangingo (hafi utwuma 200/muri 2) bifite inkuta nini (hafi mil 12 cyangwa 0.012” cyangwa 0.3 mm) bifite ubunini bw’uturemangingo bungana n’inshuro enye z’ubwikorezi bwa moteri (ni ukuvuga ingano ya silindiri ya moteri). Uko ikoranabuhanga ryo gutunganya ibikoresho n’ibikoresho ryagendaga ritera imbere, ubucucike bw’uturemangingo bwinshi, inkuta nto, n’imyenge myinshi byarashobotse.

Muri iki gihe, muri lisansi cyangwa sedan ya hybrid yo muri Amerika, hari substrates ebyiri cyangwa eshatu zikora kugira ngo zihuze n'amahame agenga ibyuka bihumanya ikirere byo muri Amerika. Muri moteri, substrate (s) zifatanye hafi zifite ubucucike bwinshi bw'uturemangingo zitanga ubuso bwinshi kugira ngo ziheshe catalyst gukora impinduka za mbere z'ibyuka bihumanya ikirere. Mu mwanya wo munsi y'ubutaka muri rusange hari substrate y'ubucucike bw'uturemangingo buciriritse kugira ngo ifashe gusukura ibyuka bihumanya ikirere bya nyuma.
