Ukusukela phakathi kwinkulungwane yama-20, amazwe ehlabathini lonke aye agxalathelana kuphando kunye nophuhliso lwamagwebu esinyithi esinamazinyo. Kwangaxeshanye, iinkqubo ezahlukeneyo zamalungiselelo ziye zandululwa enye emva kwenye. Ngokwezicelo ezahlukeneyo kunye neemfuno ezahlukeneyo zesakhiwo, iinkqubo zokulungiselela ezisetyenzisiweyo nazo zahlukile.

Ngenxa yokuba izinto ze-aluminiyam ze-foam zibonisa umkhwa omtsha wokungena phakathi kwezinto zokwakha kunye nezinto ezisebenzayo kwiinkalo ezininzi, zibonise uluhlu olubanzi lweendawo kwinkalo yezemfundo, kwaye zinethemba elibanzi lesicelo kwiinkalo zobugcisa obuphezulu kunye neenkalo zoshishino jikelele. Iimathiriyeli ezishushu zeFrontier zokhuphiswano lophando eJapan, eJamani nase China.

Ukuza kuthi ga ngoku, uphando kwishishini le-aluminium foam sele liphantse libe yiminyaka engama-70. Kula mashumi eminyaka yophando, lunjani uphuhliso lweshishini le-aluminiyam yehlabathi jikelele? Uphando lwe-aluminiyam yogwebu e-China luqale emva kwexesha. Ngaba ivele ngasemva?

1, Intshayelelo ye-aluminiyam yogwebu

Ugwebu lwe-aluminiyam lwenziwa ngokongeza izongezo kwi-aluminiyam ecocekileyo okanye ingxubevange ye-aluminiyam ngenkqubo yogwebu. Ngelo xesha, ineempawu zetsimbi kunye neebhubhu. Luhlobo olutsha lwezinto ezisebenzayo ezidibanisa isakhiwo kunye nokusebenza.

Ukusebenza kwe-aluminium foam

Ukukhanya okuphezulu

Ubuninzi be-0.2 ~ 0.4g / cm3, malunga ne-1/10 yobuninzi be-aluminium, i-1/20 yobuninzi be-titanium, i-1/30 yobuninzi bentsimbi, i-1/30 yobuninzi bentsimbi, kunye I-1/3 yobuninzi bomthi.

Ukufunxa isandi

I-aluminiyam igwebu inokufunxa amandla esandi ngokungcangcazela kodonga lwepore ukuze ivale isandi. Susa ingxolo.

Ukumelana nobushushu

Inokumelana nobushushu obuphezulu. Ngokuqhelekileyo, iqondo lobushushu lokunyibilika kwe-alloy ye-aluminium malunga ne-560 · 700°C. I-foam enye ye-aluminium ayinyibiliki nangona ishushu kwi-1400 ° C, kwaye ayikhuphi iigesi ezinobungozi kumaqondo aphezulu.

Electromagnetic wave shielding

Ugwebu lwe-aluminiyam lunokhuselo olulungileyo lwamaza ombane wombane aphezulu, anokunciphisa uphazamiseko lwe-electromagnetic ngaphezulu kwe-80%.

2. Iimveliso zogwebu zeAluminiyam

Iphepha le-Aluminiyam yogwebu

Ipaneli ehlanganisiweyo yesantiji ye-aluminiyam

Aluminiyam amagwebu amacandelo akhethekileyo

I-3, isicelo se-Aluminiyam ye-foam kunye nekhonkco yoshishino

I-Aluminiyam i-foam isetyenziswa ngokubanzi kwishishini lokwakha, ishishini le-aerospace, ishishini lokuvelisa oomatshini, ishishini lokuvelisa iimoto njalo njalo.

Ikhonkco loShishino lweAluminiyam

Entla

I-Bauxite, i-coke, i-aluminium fluoride, i-cryolite, njl.

Umlambo ophakathi

I-aluminiyam i-alloy ingots, i-aluminiyam i-alloy cast rods, i-aluminium foam

Ezantsi

Ishishini lokwakha, ishishini loomatshini, i-aerospace, ezothutho, iinqanawa zaselwandle.

4, ubume bophuhliso kunye nentsingiselo ye-aluminium foam

Ubume bophuhliso

Uphando lwe-aluminiyam i-foam ngaphambili kwihlabathi, kwaye isetyenziswe ngokubanzi kwimizi-mveliso e-United States, eJapan, eCanada nakwamanye amazwe. Uphando kunye nophuhliso lwe-aluminiyam yogwebu kwilizwe lam luqale emva kwexesha. Nangona iziphumo ezithile zophando zifunyenwe kwaye zenziwa kwimizi-mveliso, iye yathelekiswa namazwe aphuhlileyo. Xa kuthelekiswa nenqanaba loshishino kunye nesikali, kusekho umsantsa omkhulu.

Isikhokelo sophuhliso

Ukuphucula ngakumbi indlela yokwenza amagwebu kunye nenkqubo yethiyori ye-aluminiyam yogwebu;

Uphando lwenkqubo yokuvelisa i-foam ephantsi, elula, ethembekileyo kunye ne-stablealuminium;

Ukusombulula ngakumbi ingxaki yee-pores ezifanayo kwi-foam ye-aluminium;

Yandisa ngakumbi uluhlu lwesicelo se-aluminium amagwebu kwaye wandise imimandla yesicelo sayo.
