Huchi Ceramic Substrate
Synthetic cordierite imagnesium-alumino-silicate ceramic material, ingangoita yese yanhasi mizinga ye ceramic substrate catalyst substrates yakagadzirwa necordierite.
HoneHoneycomb mic substrate catalyst substrates inogadzirwa muextrusion process, mbishi zvinhu zvakaita sealumina, talc, ivhu (kaolinite), uye silica zvinoderedzwa kuita upfu uye zvinosanganiswa kuita mvura-based paste.

Synthetic cordierite imagnesium-alumino-silicate ceramic material, ingangoita yese yanhasi mizinga ye ceramic substrate catalyst substrates yakagadzirwa necordierite.
HoneHoneycomb mic substrate catalyst substrates inogadzirwa muextrusion process, mbishi zvinhu zvakaita sealumina, talc, ivhu (kaolinite), uye silica zvinoderedzwa kuita upfu uye zvinosanganiswa kuita mvura-based paste. Zvinowedzerwa zvinogona kuwedzerwa mukuita izvi zvinosanganisira mafuta ekuzora (ethylene glycol), bonding agents (eg methylcellulose), uye fluxes (alkaline hydroxides). Extrusions yakagadzirwa kubva paste yakaomeswa, yakachekwa kusvika pakureba, uye yakaverengerwa pakudziya kwepamusoro pe1400 degree.
Ceramic honeycomb substrate mifananidzo
Huchi dzeceramic substrates dzinoshandiswa mu catalytic converters dzinowanzo gadzirwa kubva kune yakakosha mhando ye ceramic material inozivikanwa se 'cordierite'. Liquid cordierite inoburitswa kuburikidza neforoma yobva yapiswa kuitira kuti inomesa uye igooma. Nekushandisa akasiyana molds, akasiyana saizi substrates anogona kuwedzeredzwa uye saizi yematanho (kana maseru) anogona zvakare kusiana. Nekuda kwekushandisa kuri kudiwa, mizinga yeuchi ye ceramic inonyatso kuenderana nepakati kana yakakura vhoriyamu zvinodiwa kunze kwekunge saizi yakajairwa inogona kushandiswa. Ceramic honeycombs ndiyo inonyanya kushandisa mari pamidziyo yevatengi yakadai sebiomass stoves uye pyrolytic self-mahovhoni ekuzvichenesa.
Saizi yemaseru ndiyo shanduko yakakosha inobatsira pakuita kwecatalytic converter. Nekudaro, pane kutaura zvakananga kuhukuru hwemaseru, zvakajairika kuverenga kuti vangani pane imwe unit yenzvimbo, semuenzaniso maseru pa square inch (cpsi) kana maseru pa square centimita.
Masubstrates anochinja zvishoma hukuru panguva yekuverenga, zvikamu zvehukuru hudiki zvinogona kugadzirwa mune imwe-nhanho nzira kuburikidza nekufanotaura kuti shanduko uye kuburitsa zvikamu kune zviyero zvakasiyana zvishoma kubva kune zvakapedzwa chigadzirwa, mahombe dhayamita, nerumwe rutivi, angangoda akawanda-matanho ekugadzira, ma substrates anowedzerwa uye anoteedzerwa kudhirowa kusvika kuhukuru hwawo, akachekwa kusvika pakureba kwekupedzisira, macontours awo anogadzirwa, ganda rekunze rinoiswa neceramic paste, uye maparts acho ovheni-yakaomeswa.
Ceramic honeycomb monoliths iripo maumbirwo: rectangular, cylinder kana ellipse, sero shapes in square, denderedzwa, hexagonal, triangle etc. tinokwanisawo kugadzirisa kugadzirwa kunoenderana nekudhirowa kwako uye samples, ceramic muzinga une cell structure density kubva pa10 kusvika 300cpsi/ 400cpsic mativi maseru (CPSIc 600 maseru).
Ceramic Honeycomb Substrate inoshandiswa mukushandura inodzimisa ine kuderera kwekuwedzera kwemafuta, nzvimbo yakakwirira chaiyo, kuderera kwemhepo, chiedza chekukurumidza-kudzima uye zvimiro zvakasiyana. Zviuru zvemasero zvinopa nzvimbo yakakwira kune yakakosha simbi inokonzeresa iyo inoshandura inokuvadza kubuda kuita mhute yemvura, kabhoni dhaidhisiki uye zvichingodaro, mizinga ye ceramics inovharira maumbirwo aripo: rectangular, cylinder kana ellipse. Maumbirwo esero ari mumativi, denderedzwa, ane hexagonal, katatu nezvimwe.
Catalyst substrate yakakosha kupesvedzera mashandiro, kusimba, uye kusimba kwecatalytic converter system, ceramic honeycomb substrate inoshandiswa mucatalytic converter yemvura ine kuderera kwekuwedzera kwemafuta, nzvimbo yakakwira chaiyo, kudonha kwemhepo, kukurumidza kudzima{0}kudzima uye zvimiro zvakasiyana, zviuru zvemasero zvinoshandura hupfu husina hupfu, hwesimbi husina hupfu. carbon dioxide uye zvichingodaro, zvinangwa zvekugadzira zveceramic catalyst substrates zvinosanganisira zvinotevera:
- Yakakwira geometric pamusoro penzvimbo (GSA),
- Nzvimbo huru yakazaruka yepamberi (OFA),
- Low thermal mass uye simba rekupisa,
- Kunyanya kushandiswa kwekushisa,
- Yakaderera coefficient yekuwedzera kwekupisa,
- Coating kuenderana,
- Simba,
- Oxidation kuramba.
