Ngikholelwa ukuthi abantu abaningi bangase bangazi ukuthi hlobo luni lwempahla uma bezwa i-foam metal? Eqinisweni, isici esikhethekile se-foam yensimbi siwukuba yinsimbi enesakhiwo esikhethekile, futhi kukhona isakhiwo esinezimbotshana ezinenani elikhulu lama-foam pores kule nto yensimbi. Lokhu kwenza futhi igwebu lensimbi libe lula kakhulu ngesikhathi lisetshenziswa; iphinde ibe nezindawo ezinhle zokuvikela ukushisa nomsindo, kanye nokuvikela kumasignali kagesi.
1. Ukwakheka kwesakhiwo se-porous
Njengensimbi ekhethekile, igwebu lensimbi linesakhiwo esifana kakhulu nesipontshi futhi siphefumula kakhulu. I-porosity yendawo yonke ye-foam yensimbi ingaphezu kuka-90%, futhi lezi zimbotshana zine-diameter yamamilimitha. Nakuba i-foam yensimbi ngokwayo inezimbotshana eziningi, lokhu akuthinti kakhulu amandla nokuqina kwayo; ngokuphambene nalokho, isakhiwo se-porous sibangela ukuba impahla yensimbi idilike ngemva kokubhekana nokucindezela, okwenza ukuba isakhiwo se-pore sidilike, okuholela ekucindezelekeni okukhulu. force area, okwenza le nto yensimbi ibe nokumuncwa okuhle kokushaqeka.
2. I-Metal Foam isetshenziswa kabanzi
Le Foam yensimbi inezinhlobonhlobo zezicelo. Njengensimbi ekhethekile enobulukhuni obuphezulu nokuqina okuphezulu, igwebu lensimbi lisetshenziswa kabanzi ku-aerospace, petrochemical, ukwakhiwa, ezokuthutha kanye nezinye izimboni. Ngenxa yezakhiwo ezinhle zokudlulisa ukushisa kwegwebu lensimbi ngokwalo, lilula kakhulu futhi liqinile, ngakho ungacishe ulibone egiyeni lokuhlala kanye namagobolondo amaphiko omkhumbi-mkhathi. Ngenxa yokuxega kanye ne-porosity ye-foam yensimbi, ukumuncwa kwayo komsindo kanye nezakhiwo zokuvala umsindo kungasetshenziswa futhi ukwenza amathambo okwenziwa, okuqinisekisa ukuthi i-foam yensimbi ingasetshenziswa njengento yokunciphisa umsindo; inohlu olubanzi kakhulu lwezinhlelo zokusebenza namathemba okusebenza.
3. Amathemba entuthuko
I-Metal Foam kungathiwa iyinsimbi ekhethekile enezici ezinhle zokufaka isicelo. Njengamanje, ocwaningweni lwesayensi, igwebu lensimbi lisetshenziswa emkhakheni wezempi. Isivikelo somzimba wezempi esingavimba izinhlamvu zokubhoboza izikhali siyathuthukiswa; ngesikhathi esifanayo, ngokusho kwezici zensimbi ye-foam ngokwayo, insimbi ye-foam yenziwa ibe yinsimbi engasindi yensimbi engagqwali ehlanganisiwe ukuze kuthuthukiswe ukuvikelwa kwemoto ehlomile, ephinde inciphise isisindo semoto yezikhali ngokwayo.
