Yiziphi izinhlobo zezinsimbi ezinegwebu?

Insimbi enegwebu, uhlobo olusha lwensimbi enenani elikhulu lama-pores angaphakathi, ithole ukunakwa okukhulu eminyakeni yamuva. Ngokuya ngohlobo lwensimbi nenqubo yokukhiqiza, izinsimbi ezinegwebu zihlukaniswa ikakhulukazi zibe izinhlobo eziningana ezifana negwebu le-aluminium, igwebu le-nickel, negwebu le-titanium. Lezi zinsimbi ezinegwebu azigcini nje ngokuba nezici zokungasindi, amandla aphezulu, ukuvimbela umlilo, nokufakwa kwe-acoustic kanye ne-thermal kodwa futhi zibonisa amandla amakhulu okusetshenziswa emikhakheni eminingi.
I-Aluminium Foam
Igwebu le-Aluminium ingenye yezinsimbi ezinegwebu, ne-aluminium njengengxenye eyinhloko. Yenziwa ngokuxuba i-aluminium noma i-aluminium ingxubevange ne-ejenti ethile egwebulile, ngemva kokuncibilika kwezinga lokushisa eliphezulu kanye nenqubo yokwenza amagwebu. Igwebu le-Aluminium linezakhiwo ezinhle kakhulu zokumunca umsindo nezivimbela ukushisa, ngakho-ke lisetshenziswa kakhulu ekwakheni, kwezokuthutha nakweminye imikhakha. Ngaphezu kwalokho, izici zayo ezingasindi kanye namandla aphezulu nazo ziyinikeza inzuzo enkulu emkhakheni we-aerospace.

I-Nickel Foam
Igwebu le-nickel kungenye insimbi ebalulekile enegwebu ene-nickel njengengxenye eyinhloko. Ine-conductivity kagesi enhle, i-ductility, nokumelana nokugqwala, ngakho-ke inezinhlobonhlobo zezinhlelo zokusebenza ku-electrochemistry, ikakhulukazi ezintweni ze-electrode zebhethri. Ngaphezu kwalokho, ukwakheka okunezimbotshana kwegwebu le-nickel kwenza kube umthwali we-catalyst omuhle kakhulu, odlala indima ebalulekile ekuphenduleni kwamakhemikhali.

I-Titanium Foam
Igwebu le-Titanium iyinsimbi enegwebu ene-titanium njengengxenye eyinhloko. I-Titanium ngokwayo inokumelana nokugqwala okuhle kakhulu, amandla aphezulu, kanye nokuminyana okuphansi, ngakho-ke igwebu le-titanium linobubanzi bezicelo ku-aerospace, ubunjiniyela basolwandle, nezinye izinkambu ezisezingeni eliphezulu. Ngasikhathi sinye, isakhiwo sayo se-porous sinikeza i-titanium foam okuhle kwe-biocompatibility, ngakho-ke iphinde ibonise amandla amakhulu emkhakheni we-biomedical.

Njengohlobo olusha lwezinto ezibonakalayo, insimbi enegwebu, enesakhiwo sayo esiyingqayizivele kanye nezakhiwo ezisebenzayo, ibonise ububanzi obuningi bezinhlelo zokusebenza emikhakheni eminingi. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, insimbi enegwebu kulindeleke ukuthi idlale izinzuzo zayo eziyingqayizivele emikhakheni eminingi futhi yenze umnikelo omkhulu ekuthuthukisweni komphakathi wesintu.
