Kuyini ukumelana nezinga lokushisa eliphezulu kwegwebu le-nickel?

Igwebu le-nickel liyinsimbi enezimbotshana ezinezimbotshana ezinezimbobo eziphakeme kakhulu endaweni ethile kanye ne-porosity, futhi izakhiwo zayo eziyingqayizivele ziyenza ibe nezinhlelo eziningi zokusebenza emikhakheni eminingi. Ukumelana nezinga lokushisa eliphezulu kwegwebu le-nickel kugxile kubacwaningi abaningi.

Ukumelana nezinga lokushisa eliphezulu kwegwebu le-nickel
Ukumelana nezinga lokushisa eliphezulu kweigwebu le-nickelikakhulukazi kuncike ezintweni zayo kanye nenqubo yokukhiqiza. Imvamisa, izinto ze-nickel foam ngokuyinhloko ziyi-nickel emsulwa, futhi iqukethe ingxenye ethile ye-aluminium, i-chromium, nezinye izakhi ze-alloying. Lezi zinto zinokuqina okuhle kokushisa nokumelana nokugqwala ngaphansi kwezimo zokushisa eziphezulu, okwenza i-nickel foam igcine ukusebenza okuzinzile ezindaweni ezishisa kakhulu. Ukuhlola kubonisa ukuthi emazingeni aphezulu okushisa angamakhulu ama-degree Celsius, ukuqina kwegwebu le-nickel akushintshanga neze, futhi i-morphology yangaphandle ayithinteki.

Iphuzu elincibilikayo legwebu le-nickel
Iphuzu elincibilikayo legwebu le-nickel lingenye yezinkomba ezibalulekile zokumelana kwayo nezinga lokushisa eliphezulu. Ngokuya ngokuminyana nokwakheka kwegwebu le-nickel, indawo yayo yokuncibilika imvamisa iba ngu-1350 ~ 1400℃. Kodwa-ke, iphuzu langempela lokuncibilika le-nickel foam lingahluka ngenxa yezinqubo ezahlukene zokulungiselela kanye nezimo zokubunjwa. Ngakho-ke, kuzinhlelo zokusebenza ezithile, ukumelana nokushisa okuphezulu kweigwebu le-nickelidinga ukuhlolwa ngokwesimo sangempela.

Ukufakwa kwezinga lokushisa okuphezulu kwegwebu le-nickel
Ukuzinza kwezinga lokushisa eliphezulu kwegwebu le-nickel kuyenza isetshenziswe kabanzi emikhakheni eminingi. Isibonelo, ezimbonini ze-petrochemical ne-iron ne-steel metallurgy, i-nickel foam ingasetshenziswa njengesihlungi samagesi aphezulu okushisa noketshezi ukuze kukhishwe ukungcola ngokuphumelelayo. Ngaphezu kwalokho, igwebu le-nickel lingasetshenziswa futhi njengempahla yokushisisa ukushisa nokupholisa uketshezi, nokugcina ukusebenza kahle kokudlulisa ukushisa emazingeni okushisa aphezulu. Ngesikhathi esifanayo, ingasetshenziswa futhi njengesiphathi se-catalysts ukuthuthukisa isivinini sokusabela kanye nomphumela we-catalytic.

Igwebu le-nickel selithole ukunakwa okusabalele ngokusebenza kwayo okuhle kakhulu kokuzinza kwezinga lokushisa eliphezulu kanye nohlu olubanzi lwamathemba ohlelo lokusebenza. Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe kanye nokuthuthuka ngokushesha kwezimboni, kukholakala ukuthi ukusetshenziswa kweigwebu le-nickelemkhakheni wamazinga okushisa aphezulu kuzoba kuningi futhi kujule.
