Yiziphi izinzuzo ze-ceramics ye-foam?

Izihlungi ze-ceramic ze-Foam seziyingxenye ebalulekile yemboni ye-metallurgical, ikakhulukazi inqubo yokuhlunga insimbi. Lezi zihlungi ziklanyelwe ukususa ukungcola kanye nokunciphisa isiyaluyalu phakathi nenqubo yokusakazwa kwezinsimbi ezincibilikisiwe njenge-aluminium, insimbi nensimbi. Eminyakeni yamuva, igwebu le-ceramic liye lazuza ukuthandwa ngenxa yezinzuzo zayo eziningi ngaphezu kwezihlungi zendabuko. Ngakho-ke, yiziphi izinzuzo ze-ceramics ye-foam?

Enye yezinzuzo ezibaluleke kakhulu zeizihlungi ze-ceramic foami-porosity yabo ephezulu kanye nendawo ethile engaphezulu. Isakhiwo se-open-cell of foam ye-ceramic sivumela insimbi encibilikisiwe ukuthi idlule ngenkathi ibamba ngempumelelo ukungcola, ama-oxides kanye ne-non-metallic inclusions. Lo mklamo oyingqayizivele uthuthukisa ikhwalithi yensimbi, unciphisa amaphutha, futhi uthuthukise izakhiwo zemishini zomkhiqizo ophelile.

Ngokungeziwe ekusebenzeni okuhle kakhulu kokuhlunga, igwebu le-ceramic libuye libe nokuzinza okuphezulu kokushisa kanye nokumelana nokushaqeka okushisayo. Isihlungi singakwazi ukumelana namazinga okushisa adlulele enqubo yokulingisa ngaphandle kokuphazamisa ubuqotho baso besakhiwo, sisenze sifaneleke uhla olubanzi lwengxubevange yensimbi nezimo zokusakaza. Lesi sakhiwo sibalulekile ukuze kuqinisekiswe ukusebenza kokuhlunga okungaguquki nokuthembekile embonini ye-metallurgical.

Enye inzuzo yegwebu le-ceramic yukuthi i-inert yamakhemikhali futhi ayiphenduli ngensimbi encibilikisiwe. Isihlungi sakhiwe ngezinto eziphikisayo ezingeke zihlangane nensimbi ekhonjiwe, okuqinisekisa ukungcoliswa okuncane kanye nekhwalithi yomkhiqizo ethuthukisiwe. Lesi sakhiwo sibaluleke kakhulu ekukhiqizeni izinga eliphezulu le-aluminium kanye nama-alloys ensimbi, lapho ngisho nokungcola okuncane kungaba nomthelela omkhulu kumkhiqizo wokugcina.

Igwebu le-Ceramic liyaziwa futhi ngamandla ayo okusebenza kahle kakhulu nokuqina. Isihlungi singakwazi ukumelana nokucindezela kanye nesiyaluyalu senqubo yokusakazwa kwensimbi, okuholela ekuhlungeni okungaguquki, okuthembekile. Isimo sabo esimangelengele futhi esihlala isikhathi eside sinciphisa ingozi yokuphuka noma ukwehluleka ngesikhathi sokusetshenziswa, ekugcineni konga izindleko futhi kwandise ukukhiqiza kokusebenza kokusakazwa kwensimbi.

Ukwengeza, i-ceramic foam inobungani bemvelo futhi iyasimama. Lezi zihlungi zingasetshenziswa kabusha futhi zingaphinda zisetshenziswe ngemva kokusetshenziswa, kuncishiswe imfucuza futhi kunciphise umthelela ophelele wemvelo wenqubo yokuphonswa kwensimbi. Lesi simo esivumelana nemvelo sihambisana nokugcizelelwa okukhulayo kwezinqubo zokukhiqiza ezisimeme kanye nokunciphisa udoti wezimboni.

Kafushane, izihlungi ze-ceramic foam zinezinzuzo eziningi ngaphezu kwezihlungi zendabuko embonini yensimbi. I-porosity yabo ephezulu, ukuzinza kokushisa, ukungabi namandla kwamakhemikhali, amandla emishini kanye nokusimama kwendawo ezungezile kubenza babe yisinqumo sokuqala sokusebenza kokusakazwa kwensimbi. Njengoba isidingo semikhiqizo yensimbi ephezulu siqhubeka sikhuphuka, igwebu le-ceramic ngokungangabazeki lizodlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokuthembeka kwezinqubo zokuhlunga insimbi. Ngocwaningo oluqhubekayo nokuthuthuka kobuchwepheshe bezinto ezibonakalayo, izitsha zobumba zegwebu zinekusasa eliqhakazile emikhakheni yokusakazwa kwensimbi nokusansimbi.
