Litšobotsi tsa Sebopeho sa Lisebelisoa tsa Foam ea Aluminium

Aluminium foam e entsoe katšepe ea aluminiumlisebelisoa tsa matrix le li-pores. Likarolo tsa sebopeho sa foam ea aluminium li kenyelletsa bophara ba pore, porosity kapa letsoalo le lekanyelitsoeng, pore roundness, le sebaka se ikhethileng. Khokahano lipakeng tsa meaho ea pore e ka aroloa e le foam ea aluminium ea sele e bulehileng lefoam ea aluminium e koetsoeng, Kabo ea pore ea foam ea aluminium hangata e na le tšohanyetso, empa mekhoa e tobileng e ka finyella kabo e hlophisehileng. Sebopeho sa li-pores e ka ba sebopeho sa lisele tse koetsoeng, sebopeho sa lisele tse bulehileng, kapa motsoako oa bobeli. Li-pores tsabubble-cell aluminium foamli hokahane, ha li-pores tsa foam ea aluminium e koetsoeng e ikemetse ebile e arohane ho tloha ho e mong e le hore foam ea aluminium e ka nkoa e le lisebelisoa tse nang le likarolo tse peli: matrix a aluminium le li-pores. Sebopeho sa lisele tse koetsoeng: marako a pore a koaletsoe ka ho feletseng, 'me khase e phuthetsoe ka har'a li-pores, e nang le liphello tse ntle tsa molumo le mocheso oa mocheso' me e atisa ho sebelisoa ho monya matla, ho thibela ho thulana, le masimo a mang. Sebopeho sa lisele tse bulehileng: marako a pore a kopantsoe, a nang le moea o motle oa ho phunyeletsa le ho tsamaisa metsi, a loketse ho hloekisa, ho senya mocheso, le maemo a mang. Kaha mekhahlelo ea sebopeho sa foam ea aluminium e khetholla ka ho toba ts'ebetso ea foam ea aluminium, ka mekhoa e sebetsang, lisebelisoa tsa aluminium tse nang le lisebelisoa tse nepahetseng li lokela ho khethoa ho ea ka likopo tse fapaneng. Ha ho bapisoa le lisebelisoa tsa tšepe tse tloaelehileng, foam ea aluminium e khetholloa ke boholo bo boholo ba pore (boholo ba pore D = 0.2 mm ho ea ho 8 mm), porosity e phahameng (porosity 63% ho 90%), le boima bo tlaase. Sebopeho sa marapo aaluminium foame bonts'a kabo ea likarolo tse tharo tsa reticular, e nang le likarolo tse tiileng tsa motsoako oa aluminium. Reticulation ena e fana ka lisebelisoa tse ntle haholo tsa mochini, joalo ka matla a khethehileng le ho monya matla a matle. Sebaka se ka ntle sa foam ea aluminium hangata se na le li-pores tse bonahalang, empa boleng ba bokaholimo bo ka ntlafatsoa ka ho phekoloa ka morao (mohlala, ho roala, ho sebetsa).

Ka kakaretso, litšobotsi tsa sebopeho sa foam ea aluminium ke porosity ea eona, e bobebe le matla a phahameng, le skeleton e nang le mahlakore a mararo. Mehaho ena ea meralo e etsa qeto ea ts'ebeliso ea eona e pharaletseng libakeng tsa acoustic le thermal insulation, ho monya matla, ho hanyetsa tšusumetso, ho sefa, le kaho e bobebe.

Litšobotsi tsa sebopeho sa aluminium e foamed: (a) aluminium e nang le foamed e nang le lisele tse bulehileng; (b) aluminium e foamed e haufi-ufi
