Avalekile iseli elimunca umsindo kanye nebhulokhi ye-Aluminium Foam evimbela umsindo
1.Okuqukethwe kwamakhemikhali.
Iphaneli ye-Aluminium Foam: 97% i-aluminium powder, i-ejenti enegwebu engu-3%, i-1% TiH2
I-viscose ekhulayo, i-2% ye-Ca. Iyingxenye yokuvikela imvelo ayinakho ukungcola.

2.Izici zikagesi zezinto zokwakha.
I-conductivity ye-aluminium foam material incane kakhulu kunento eqinile ye-aluminium.
I-thermal conductivity ye-aluminium foam incane kakhulu kune-aluminium eqinile, cishe izikhathi ezingu-0.1 - 0.2 ze-aluminium eqinile.
Ngaphezu kwalokho, i-aluminium eyigwebu nayo inokuqina, okungashi, akulula ukwenza i-oxidation, akulula ukukhiqiza ukuguga, ukumelana nesimo sezulu esihle,izici ezinhle zokuvuselela nokuvuselela.
Ukusebenza okuhle kakhulu kokuvikela i-electromagnetic: lapho i-electromagnetic wave frequency ingu-2.6-18GHZ,
amandla kazibuthe evikela igwebu le-aluminium angafinyelela ku-60-90dB.
3.Izici zezinto zokwakha.
Ukumelana nokugqwala: endaweni yasolwandle ukuchayeka emkhathini unyaka wonke, akukho okungavamile okusobala:
isimo sokugqwala esisheshisiwe, ukuhlolwa kwesifutho sikasawoti wamanzi iminyaka engu-2 ngaphandle kokukhetha.Bonisa ukuthi ukumelana nokugqwala kwegwebu le-aluminium kuhle kakhulu.
Ukwenza isifutho se-anti-corrosion surface, thuthukisa ukumelana nokugqwala.
4.Izici ze-Acoustic.
20-40dB
5.Izici zokudlidliza.
Ukumuncwa okunamandla komthelela wamandla, ukusebenza kahle kwamandla ngokuyisisekelo kungafinyelela ngaphezu kwama-50%, ukusebenza kahle kwendawo yesikhulumi ka-80% kuya ku-90%, kungaba ukumuncwa okuhle kwamandla angaphandle, kunciphise umthelela womonakalo.
I-Foam aluminium damping ikakhulukazi ibhekisela ekumunceni kwayo okuhle kokushaqeka noma umthamo wamandla omfutho. Ukumuncwa ukushaqeka noma ukumelana nomthelela kubaluleke kakhulu ezimotweni zokuthutha. I-aluminium eyigwebu ingcono kunezinye izinto zegwebu ukuze imunce umthamo wamandla omthelela, i-isotropic ekusebenzeni, iyinto efanelekile yebhafa.
Ukusebenza okuphezulu kokudambisa kanye nezinga lokumunca amandla nomthelela: umthamo wokudambisa we-aluminium yensimbi izikhathi ezi-5-10.
Igwebu le-aluminium eline-porosity engu-50% likwazi ukumunca amandla angaphezu kuka-2.5MJ/M3C uma inokuhluka okungu-84%.
Sika imiphetho engajwayelekile iqonde phezulu.
Sika ugqinsi oludingwa amakhasimende ukwenza igwebu le-aluminium
