Khuluma nge-Honeycomb Ceramics

Isingeniso somkhiqizo:

I-ceramics ye-honeycomb iwuhlobo olusha lomkhiqizo we-ceramic onesakhiwo esifana nekhekhe lezinyosi. Yenziwe ngezinto ezingavuthiwe ezifana ne-kaolin, i-talc, impushana ye-aluminium, nobumba. Inezimo ezihlukahlukene ezakhiwe izimbobo ezingenakubalwa ezilinganayo. Inombolo enkulu yezimbobo ifinyelele ku-120-140 ngesentimitha yesikwele, ukuminyana kungu-0.3-0.6 amagremu nge-cubic centimeter ngayinye, futhi izinga lokumunca amanzi liphezulu njenge-20%. Lesi sakhiwo esinezimbotshana ezinodonga oluncane sandisa kakhulu indawo yejometri yesithwali futhi sithuthukisa ukumelana nokushaqeka okushisayo. Izimbobo ezinezikhala zamakhekheba ezinyosi zingonxantathu futhi ziyisikwele, phakathi kwazo izimbobo ezingunxantathu zinamandla okuthwala kangcono kunezimbobo eziyisikwele kanye nezimbobo eziningi, okubaluleke kakhulu njengesithwali se-catalytic. Ngokukhula kwenani lezimbobo endaweni ngayinye yeyunithi kanye nokuncipha kokuqina kodonga lwe-pore yesithwali, ukumelana nokushaqeka okushisayo kwesiphathi se-ceramic kuyathuthukiswa, futhi izinga lokushisa lomonakalo wokushaqeka oshisayo liyakhuphuka. Ngakho-ke, i-ceramics yezinyosi kufanele inciphise i-coefficient yokwandisa futhi ikhulise inani lemigodi endaweni yeyunithi.

Izinto ezisetshenziswayo eziyinhloko:

I-Cordierite, i-mullite, i-aluminium porcelain, i-alumina ephezulu, i-corundum, njll.

Isicelo somkhiqizo:

I-1) Njengomzimba wokugcina ukushisa: Umthamo wokushisa we-honeycomb ye-ceramic yokugcina ukushisa komzimba ungaphezu kuka-1000kJ/kg, futhi izinga lokushisa eliphezulu lokusebenza lomkhiqizo ngu-≥1700℃. Ingonga uphethiloli ongaphezu kuka-40% ezithandweni zokushisisa, okosa, ezithandweni ezicwiliswayo, izithando zomlilo eziqhekekayo nezinye iziko, inyuse ukukhiqizwa ngamaphesenti angaphezu kuka-15, kanti izinga lokushisa legesi ekhishwayo lingaphansi kuka-150 ℃.

2) Njengesigcwalisi: Izithako ze-ceramic zekhekhe lezinyosi zinezinzuzo njengendawo enkulu ethile engaphezulu namandla angcono kunezinye izimo zokugcwalisa. Bangenza ukusatshalaliswa koketshezi lwegesi kube okufanayo, kunciphise ukumelana nombhede, kube nemiphumela engcono, futhi kunwebe impilo yesevisi. Zisebenza kahle kakhulu njengezigcwalisi ezimbonini ze-petrochemical, zemithi kanye nezinhle zamakhemikhali.

3) Njengesithwali se-catalyst: I-ceramics yezinyosi inezinzuzo eziningi kuma-catalysts. Ukusebenzisa izinto ze-ceramic zekhekheba lezinyosi njengabathwali, zisebenzisa izinto zokumboza eziyingqayizivele, futhi zilungiswe ngezinsimbi eziyigugu, izinsimbi zomhlaba ezingavamile nezinsimbi zokuguqulwa, zinezinzuzo zomsebenzi ophezulu we-catalytic, ukuzinza okuhle kokushisa, impilo ende yesevisi, amandla aphezulu, njll.

4) Njengesihlungi sezinto: ukuzinza okuhle kwamakhemikhali, ukumelana ne-asidi, i-alkali kanye ne-organic solvents; ukumelana okuhle kakhulu kokushisisa nokupholisa okusheshayo, izinga lokushisa lokusebenza lingaba phezulu njenge-1000 ℃; izakhiwo ezinhle ze-antibacterial, ezingonakaliswa kalula amagciwane, akulula ukuvinjelwa futhi kulula ukuzivuselela; ukuzinza okuqinile kwesakhiwo, ukusabalalisa usayizi wembobo emincane, ukungena okuphezulu; okungewona ubuthi, okulungele ikakhulukazi ukudla nezidakamizwa.
