Iyini i-Honeycomb Ceramics?

Eminyakeni yamuva nje, isidingo sezinto zokwakha ezinobungani nemvelo nezisebenza kahle besilokhu sikhula kuzo zonke izimboni ezahlukene. Enye yezinto ezintsha eziye zadonsa ukunaka kwabacwaningi nonjiniyela yi-honeycomb ceramics. Le nto inesakhiwo esiyingqayizivele se-honeycomb, esinikeza izinzuzo eziningi kanye nokuguquguquka ekusetshenzisweni kwayo. Isihloko esilandelayo sinikeza ukuhlola okujulile kwe-honeycomb ceramics, sixoxa ngezinhlobo zazo, izici, ukwakheka kwamakhemikhali, inqubo yokulungiselela, kanye nobuningi bezicelo ezimbonini ezifana nezimoto, amakhemikhali, amandla kagesi, nokuningi. Ngokuqonda amandla e-honeycomb ceramics, singasebenzisa kangcono izinzuzo zazo futhi sivule indlela yekusasa elizinzile nelisebenza kahle emikhakheni eminingi.

1、Iyini i-Honeycomb Ceramics

I-Honeycomb ceramics iwumkhiqizo omusha we-ceramic onesakhiwo esifana nesimo se-honeycomb. Ekuqaleni yayisetshenziswa ekuhlanzweni komoya omncane emotweni, futhi manje isetshenziswa kabanzi ezimbonini ezifana namakhemikhali, amandla kagesi, i-metallurgy, i-petroleum, i-electronics, kanye nemishini, ngezinhlelo zokusebenza ezibanzi kakhulu kanye namathuba athembisayo. I-Honeycomb ceramics ingenziwa ngezinto ezahlukahlukene, ikakhulukazi okuhlanganisa i-cordierite, i-mullite, i-alumina titanate, i-activated carbon, i-silicon carbide, i-activated alumina, i-zirconia, i-silicon nitride, kanye ne-composite matrices.

2、Izinhlobo ze-Honeycomb Ceramics

Izitsha zobumba zezinyosi zingahlukaniswa ngezigaba ezine ezinkulu ngokusekelwe ekusetshenzisweni kwazo: izindawo zokugcina ukushisa, izinto zokupakisha, izithwali ze-catalyst, kanye nezinto zokuhlunga.

Izithombo zokugcina ukushisa ze-ceramic ze-honeycomb zinamandla okushisa angaphezu kuka-1000 kJ/kg, kanti izinga lokushisa lokusebenza eliphakeme kakhulu lingu-1700℃. Zingonga uphethiloli ongaphezu kuka-40% ezithandweni ezifana nezithando zokushisa, ama-oven okubhaka, izithando ezi-homogenizing, kanye nezithando zokuqhekeka, zandise umkhiqizo ngaphezu kuka-15%, futhi zehlise izinga lokushisa lomusi okhishwayo libe ngaphansi kuka-150℃.

Izinto zokupakisha ezenziwe ngobumba be-honeycomb zinendawo enkulu ethile kanye namandla angcono kunezinye izinto zokupakisha ezimile, okuholela ekusakazweni okufanayo kwegesi noketshezi, ukwehla kokumelana kombhede, ukusebenza okungcono, kanye nokuphila isikhathi eside kwenkonzo. Zisetshenziswa njengezinto zokupakisha ezimbonini ze-petrochemical, zemithi, kanye nezamakhemikhali amahle ngempumelelo enkulu.

Izitsha zobumba ze-honeycomb zinenzuzo ikakhulukazi uma zisetshenziswa njengezinto zokukhulisa. Zisebenzisa izinto zobumba ze-honeycomb njengezithwali futhi zisebenzisa izinto zokugqoka ezihlukile, zilungiswa ngezinsimbi eziyigugu, izinsimbi zomhlaba ezingavamile, kanye nezinsimbi zokuguquka, okuholela ekusebenzeni okuphezulu kwe-catalytic, ukuzinza okuhle kakhulu kokushisa, impilo ende yenkonzo, kanye namandla aphezulu.

3、Izici ze-Honeycomb Ceramics

Amandla aphezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, kanye nokumelana nokuguguleka kwenza izitsha zobumba zezinyosi zifanelekele izinkambu ezahlukene zokuvikela imvelo. Ezinye izakhiwo zifaka:

Indawo ephezulu

Ububanzi be-porety ephezulu kanye nobubanzi be-pore obufanayo

Ukwehla kwengcindezi okuphansi

I-coefficient yokwanda kokushisa okuphansi

Ukushaqeka okuphezulu kokushisa kanye nokumelana nokudlidliza

Ukumelana okuphezulu nokugqwala kwamakhemikhali (i-anti-acid ≥99.8%)

Amandla aphezulu okucindezela

4、Ukwakheka Kwamakhemikhali Kwezinto Zobumba Zezinyosi

Ama-honeycomb e-ceramic ngokuvamile enziwa nge-kaolin, i-talc, i-aluminium powder, kanye nobumba. Namuhla, ngokungeza i-zeolite nezinye izinto eziphikisayo, ezinye izakhiwo zingatholakala kulezi zinto.

Izinto zokwakha (i-MOC):

I-Cordierite

Ukwakheka kwamakhemikhali e-Cordierite:

I-Alumina: 35.2±1.5%

I-Silica: 50.9±1.5%

I-Magnesia: 13.9±1.5%

5、Inqubo Yokulungiselela I-Honeycomb Ceramics

Izinto zobumba ze-honeycomb zingenziwa ngezinto ezahlukahlukene. Izinto eziyinhloko zifaka phakathi i-cordierite, i-mullite, i-aluminium titanate, i-activated carbon, i-silicon carbide, i-activated alumina, i-zirconia, i-silicon nitride, kanye nezingxenye ezihlanganisiwe ze-cordierite-mullite kanye ne-cordierite-aluminum titanate.

Ngemva kokwenza i-activated carbon powder noma ama-granule abe yisakhiwo se-ceramic se-honeycomb, amandla okuhlanza nokwelapha amanzi angcolile athuthukiswa kakhulu, ikakhulukazi embonini yezemithi yokususa ukungcola, ukuphelelwa amanzi emzimbeni, kanye nokususa umbala wama-antibiotic, ama-hormone, amavithamini, imijovo ye-nucleic acid, kanye neminye imijovo nemithi ehlukahlukene. Njengoba i-honeycomb ceramics yakhiwa ngokusebenzisa i-extrusion, izithasiselo ezahlukahlukene kumele zengezwe ezintweni zokusetshenziswa eziyinhloko ukuze kuthuthukiswe i-plasticity kanye nokugeleza komzimba wobumba. Lezi zithasiselo zifaka kakhulu ama-binder, ama-plasticizer, ama-deflocculant, ama-lubricant, nama-wetting agents. Ngaphezu kwalokho, kukhona nama-agent okugcina amanzi, ama-chelating agents, ama-antistatic agents, ama-colloidal protectants, nama-surfactants. Njengamanje, isitashi, i-carboxymethyl cellulose, kanye ne-polyvinyl alcohol kusetshenziswa kabanzi njenge-binder, i-tung oil kanye ne-stearic acid njenge-lubricant, kanye ne-glycerin njenge-plasticizer.

6、Ukusetshenziswa kwe-Honeycomb Ceramics

Izithwali ze-Catalyst

Uma zisetshenziswa njengezithwali ze-catalyst, izitsha ze-honeycomb zisetshenziswa kakhulu ekuhlanzweni kokukhishwa kwezimoto, ukucisha igesi ye-boiler flue (NOx), ukususa iphunga lokukhishwa kwezimboni, kanye nokususa amagesi anobuthi nayingozi. Izitsha ze-honeycomb ceramic catalyst ezisetshenziswa ekuhlanzweni kokukhishwa kwezimoto ikakhulukazi ziyizitsha ze-honeycomb cordierite ezimbozwe nge-γ-Al2O3.

Ifenisha Yesitofu Esingenasivikelo

Ifenisha yesitofu se-ceramic se-honeycomb ekhishwe ngaphandle inesisindo esilula ngo-60%-75% kunefenisha yesitofu sendabuko, okuvumela ukudluliselwa kokushisa okusheshayo kanye nokushisa okusheshayo. Ukusebenzisa izitofu ze-honeycomb njengezisekelo zokudubula ama-ferrite noma ezinye izitofu ze-elekthronikhi kusiza ukuthuthukisa ukusebenza kwemikhiqizo.

Izihlungi Zokugeleza Kodonga

Izitsha zobumba zezinyosi ezinezindonga ezincane nezinezimbobo zingasetshenziswa ukuhlunga nokuhlanza izinhlayiya zekhabhoni kumagesi okukhipha ugesi enjinini yedizili (cishe ku-500℃).

7、Ekuphetheni, i-honeycomb ceramics iyizinto eziguquguqukayo nezintsha ezinesakhiwo se-honeycomb esiyingqayizivele esinikeza izinzuzo ezahlukahlukene. Zisetshenziswa ezimbonini eziningi ezahlukene, kufaka phakathi izimoto, amakhemikhali, amandla kagesi, i-metallurgy, i-petroleum, i-electronics, kanye nemishini. Izakhiwo zazo ezinhle kakhulu, njengokuqina okuphezulu, ukumelana nokushisa okuphezulu, ukumelana nokugqwala, kanye nokumelana nokuguguleka, kuzenza zifanelekele izinhlelo zokusebenza ezahlukahlukene, kufaka phakathi izindawo zokugcina ukushisa, izinto zokupakisha, izithwali ze-catalyst, kanye nezinto zokuhlunga. Ngokuthuthuka okuqhubekayo kwesayensi yezinto ezibonakalayo kanye nesidingo esikhulayo sezinto ezinobungani nemvelo nezisebenzayo, i-honeycomb ceramics cishe izodlala indima ebaluleke kakhulu ezimbonini ezahlukene, ithembisa ikusasa eliqhakazile ngentuthuko yazo kanye nezinhlelo zokusebenza.
