Yiziphi izigaba nezinto zokuhlunga ze-ceramic foam?

Izinto eziyisisekelo zesihlungi se-ceramic foam ziyii-silicon carbide, i-zirconium oxide ne-alumina
Isihlungi se-ceramic esiyigwebu sinomphumela omuhle wokuhlunga emanzini ethusi noma ensimbi, samukela isakhiwo esinezinhlangothi ezintathu, sisusa ngempumelelo izingxube ezixutshwe ne-oxidized nezinye izingxube ezingezona ezensimbi, ukuvimbela ukuthwebula nokukhangisa. Kungakhathaliseki ukuthi iyinsimbi empunga, i-ductile iron noma i-shaft, isilinda noma izingxenye ezinkulu eziyinkimbinkimbi, izingxenye zokusakaza ezinembayo ezihlungiwe, ikhwalithi yomkhiqizo izoba yimiphumela egculisayo.
Izihlungi ze-Ceramic Foamnazo zifanele ithusi, ithusi, ithusi nezinye izingxube zethusi, ukunciphisa i-copper liquid turbulence kanye nokulungisa nokuhlanza insimbi encibilikisiwe. Okubaluleke kakhulu ukunwetshwa okubalulekile kwempilo yesevisi yokulingisa ithusi ezindaweni ezifunwa kakhulu noma ezinokhahlo njengeziphehlisi zemikhumbi yasolwandle, izingxenye zamakhemikhali, njll. Iphinde ibe nemiphumela emihle yokusakazwa kwethusi okunezidingo zokupholisha phezulu. Izihlungi ze-ceramic ze-Foam nazo zidlala indima ebalulekile ekukhiqizeni ithusi lendabuko, ukukhiqizwa kwethusi le-elekthronikhi kanye nezinqubo eziqhubekayo zokuphonsa nokugingqa. Ngenxa yengxenye enkulu yethusi nama-alloys, okuhlanganisa ama-alloys e-zinc, akhiqiza ukushaqeka okukhulu okushisayo phakathi nenqubo yokuphonsa, ukusetshenziswa kwe-silicon carbide foam ehlanganiswe izihlungi ze-ceramic ngokuvamile kungaphansi kwemithetho eqinile ngosayizi.
Okubalulekile
Impahla eyisisekelo yezihlungi ze-ceramic i-oxidized clean Zr02.izihlungi ze-zirconiazinezinga lokushisa elimelana nokushisa elingaphezu kuka-1760°C, amandla aphezulu nomthelela omuhle wezinga lokushisa eliphezulu.
Izingxenye zensimbi ye-Cast zisetshenziswa kakhulu lapho kudingeka khona amandla aphezulu kanye nobude. Ngakho-ke, izingxenye zensimbi ezikhonjiwe zizwela kakhulu ekungcoleni okubangelwa ukungcola, futhi izici ezinhle kakhulu zezihlungi ze-ceramic ze-foam zingasusa ngempumelelo ukungcola okuholela ekugcineni ikhwalithi yomkhiqizo isikhashana. Ukungcola ngokuyinhloko kuhlanganiswe izinhlayiya ezingezona ezensimbi, i-slag kanye nemfucumfucu ephikisayo, okuthuthukisa ikhwalithi ephezulu kanye nezakhiwo zemishini yokukhipha futhi kunciphisa izinga le-scrap.
Isihlungi segwebu le-Ceramic singenza insimbi ewuketshezi igcwalise umgodi ngokulinganayo, futhi insimbi encibilikisiwe inomkhuba omkhulu wokuphazamiseka ekuthululeni. Isakhiwo sezimbotshana ezinezinhlangothi ezintathu ze-isihlungi se-ceramic foamukugeleza kweziyaluyalu ekugcineni kuguqulwe kube ukugeleza kwe-laminar ezinzile kakhulu. Ukugeleza kwe-laminar kugcwalisa kangcono umgodi, ngaleyo ndlela kunciphisa ukugqwala komthelela wesixazululo sensimbi emgodini wokuphonsa futhi kunciphisa kakhulu izinga lokulahla.
