Izici Zesakhiwo Sezinto Zokusebenza Ze-Aluminium Foam

Igwebu le-aluminium lakhiwe nge-insimbi ye-aluminiumi-matrix kanye nama-pores. Amapharamitha wesakhiwo segwebu le-aluminium afaka phakathi ububanzi bembotshana, i-porosity noma ukuminyana okuhlobene, ukujikeleza kwezimbotshana, kanye nendawo ethile. Ukuxhumana phakathi kwezakhiwo ze-pore kungahlukaniswa njenge-open-cell aluminium foam kanyei-aluminium foam evaliwe, Ukusatshalaliswa kwe-pore kwegwebu le-aluminium ngokuvamile akuhleliwe, kodwa izinqubo ezithile zingafinyelela ukusabalalisa okuhlelekile. Ukuma kwama-pores kungaba isakhiwo seseli evaliwe, isakhiwo se-open-cell, noma inhlanganisela yakho kokubili. Izimbotshana zei-open cell aluminium foamaxhunyiwe, kuyilapho izimbotshana ze-aluminium foam evaliwe zizimele futhi zihlukaniswe komunye nomunye ukuze igwebu le-aluminium lithathwe njengento eyinhlanganisela yezigaba ezimbili: i-aluminium matrix kanye nama-pores. Ukwakhiwa kwamaseli avaliwe: izindonga ze-pore zivaleke ngokuphelele komunye nomunye, futhi igesi igoqwe emigodini, enomsindo omuhle nemiphumela yokushisa ukushisa futhi isetshenziselwa ukumuncwa kwamandla, ukulwa nokushayisana, nezinye izinkambu. Isakhiwo se-Open-cell: izindonga ze-pore zixhunyiwe, ezinokungena kahle komoya kanye nokuhanjiswa kwamanzi, ezifanele ukuhlunga, ukuchithwa kokushisa, nezinye izimo. Njengoba imingcele yesakhiwo se-aluminium foam inquma ngokuqondile ukusebenza kwe-aluminium foam, ekusebenziseni okungokoqobo, izinto ze-aluminium foam ezinemingcele ezifanele kufanele zikhethwe ngokuvumelana nezinhlelo zokusebenza ezahlukene. Uma kuqhathaniswa nezinto zensimbi zendabuko, i-aluminium Foam ibonakala ngobukhulu obukhulu be-pore (usayizi we-pore D = 0.2 mm kuya ku-8 mm), i-porosity ephezulu (i-porosity 63% kuya ku-90%), kanye nobukhulu obuphansi. Isakhiwo samathambo wei-aluminium foamibonisa ukusatshalaliswa kwe-reticular enezinhlangothi ezintathu, okuhlanganisa izingxenye eziqinile zengxubevange ye-aluminium. Lokhu kushintshanisa kunikeza okokusebenza izici ezinhle kakhulu zomshini, njengamandla athile aphezulu kanye nokumuncwa okuhle kwamandla. Ingaphandle legwebu le-aluminium livame ukuba lukhuni nezimbotshana ezibonakalayo, kodwa izinga eliphezulu lingathuthukiswa ngokwelashwa ngemva kokwelashwa (isb., ukumbozwa, ukukhanda).

Sekukonke, izici zesakhiwo segwebu le-aluminium ukuqina kwayo, ukungasindi kanye namandla aphezulu, kanye nohlaka lwamathambo olunezinhlangothi ezintathu. Lezi zakhiwo zesakhiwo zinquma ukusetshenziswa kwayo okubanzi emikhakheni ye-acoustic ne-thermal insulation, ukumuncwa kwamandla, ukumelana nomthelela, ukuhlunga, kanye nokwakhiwa kwe-lightweight.

Izici zesakhiwo se-aluminium enegwebu: (a) i-aluminium enegwebu eneseli evulekile; (b) i-aluminium enegwebu enamaseli aseduze
