Ndiyakholelwa ukuba abantu abaninzi banokungazi ukuba luhlobo luni lwezinto eziphathekayo xa beva isinyithi se-foam? Enyanisweni, into ekhethekileyo ye-foam yensimbi yinto yensimbi enesakhiwo esikhethekileyo, kwaye kukho isakhiwo se-porous kunye nenani elikhulu le-foam pores kule nto yensimbi. Oku kwenza ukuba i-foam yesinyithi ibe lula kakhulu ngexesha lokusetyenziswa; Ikwanazo neempawu ezilungileyo zokugquma kwe-thermal kunye nesandi, kunye nokukhusela kwiimpawu zombane.
1. Ukuqulunqwa kwesakhiwo se-porous
Njengesixhobo esikhethekileyo sesinyithi, i-foam yensimbi inesakhiwo esifana kakhulu neso sipontshi kwaye siphefumla kakhulu. I-porosity yendawo yonke ye-foam yensimbi ingaphezulu kwe-90%, kwaye le mibhobho inobubanzi beemilimitha. Nangona i-foam yensimbi ngokwayo inama-pores amaninzi, oku akuchaphazeli kakhulu amandla kunye nokuqina kwayo; ngokuchaseneyo, isakhiwo se-porous sibangela ukuba izinto zetsimbi ziwe phantsi emva kokudibana noxinzelelo, kubangela ukuba isakhiwo se-pore sidilike, kubangele uxinzelelo olukhulu. indawo yamandla, eyenza le nto yentsimbi ibe nokufunxa kakuhle ukothuka.
2. I-Metal foam isetyenziswa kakhulu
Le foam yesinyithi inoluhlu olubanzi kakhulu lwezicelo. Njengentsimbi ekhethekileyo enobunzima obuphezulu kunye nokuqina okuphezulu, i-foam yensimbi isetyenziswa ngokubanzi kwi-aerospace, i-petrochemical, ukwakhiwa, ukuthutha kunye namanye amashishini. Ngenxa yeepropathi ezilungileyo zokuhambisa ubushushu bentsimbi yegwebu ngokwayo, ilula kakhulu kwaye iqinile, ngoko ungaphantse uyibone kwigiya yokumisa kunye namaqokobhe amaphiko e-spacecraft. Ngenxa yokukhululeka kunye ne-porosity ye-foam yensimbi, ukufunxa isandi kunye neempawu zokugquma isandi nazo zingasetyenziselwa ukwenza amathambo okwenziwa, okuqinisekisa ukuba i-foam yensimbi ingasetyenziselwa njengento yokunciphisa ingxolo; inoluhlu olubanzi kakhulu lwezicelo kunye nezicelo ezilindelekileyo.
3. Amathuba ophuhliso
I-foam ye-Metal inokuthiwa yinto ekhethekileyo yensimbi kunye nethemba elihle lokufaka isicelo. Okwangoku, kuphando lwezenzululwazi, i-foam yensimbi isetyenziswa kwintsimi yomkhosi. Kuphuhliswe isikrweqe somzimba somkhosi esinokuvala iimbumbulu zokugqobhoza; kwangaxeshanye, ngokweempawu zetsimbi ye-foam ngokwayo, isinyithi se-foam senziwe kwi-lightweight steel stainless composite material ukwenzela ukuphuculwa kokhuseleko lwesithuthi esixhobileyo, esibuye sinciphise ngakumbi ubunzima besithuthi esixhobileyo ngokwaso.
