1. Iimpawu zesithethi:
Ukusebenza kwesandi sokufunxa: Ipleyiti ye-aluminium ye-foam evaliweyo inokugqojozwa ukwenza ibhodi yokufunxa isandi kunye nesantya esiphezulu sokufunxa isandi. Xa izinga lokuvula liyi-1% ~ 3%, izinga lokufunxa isandi liphezulu. Isantya sokufunxa isandi esilinganiswe yindlela yokuma yamaza kuluhlu lwe-1000Hz ukuya kwi-2000Hz, kwaye isantya sokufunxa isandi sifikelela kwi-40% ukuya kwi-80%.
Isiphumo sokugquma kwesandi se-aluminiyam yogwebu: ibhodi yokugquma isandi eyenziwe ngephaneli yesangweji ye-aluminiyam enogwebu, ubukhulu obuyi-20mm, ukugqunywa kwesandi: 20 ~ 40dB.
2. Ukuxhathisa imozulu:
Ukumelana nokukhula: ukuchanabeka kwi-atmosfera yaselwandle unyaka omnye, akukho nto ingaqhelekanga; phantsi kweemeko ezikhawulezayo zomhlwa, uvavanyo lokutshiza ityuwa lokutshiza amanzi alunanto ingaqhelekanga iminyaka emi-2; ibonisa ukuba ukuxhathisa umhlwa kwealuminiyam enogwebu kuhle kakhulu.
Akukho kufunxa ukufuma: Izinga lokufunxa ukufuma kwealuminiyam enogwebu yi-0.0%. Akukho ukufunxa ukufuma, kwaye akukho kuthotywa kokusebenza kwe-acoustic ngenxa yokufuma.
Iipropati ezikwazi ukumelana nobushushu / ezingenakutsha: I-aluminium enegwebu ithambile kwiqondo lokushisa eliphezulu le-600 ° C, kwaye yinto engenakutsha.
Ukusebenza kwe-insulation: I-thermal conductivity ye-aluminium enogwebu yi-0.25 ~ 0.62W / mK, elingana ne-marble, kwaye inokusebenza kakuhle kwe-insulation.
Ukuzinza kwe-Thermal: I-coefficient yokwandiswa komgca we-aluminium enegwebu yi-1.934 * 10 ℃, elingana nekhonkrithi, kwaye akulula ukuba ukhubazeke ngubushushu.
3. Iimpawu zoomatshini:
Iimpawu zomatshini: amandla oxinzelelo: 3 ukuya kwi-17 MPa; amandla e-flexural: 3 ukuya kwi-15 MPa; amandla okuqina: 2 ukuya kwi-7 MPa;
Ukusebenza kweCushioning: Ukufunxa amandla kunokufikelela kwi-8J/cm3～30J/cm3, kwaye i-aluminiyam enogwebu inokufunxa amandla ngoguquko, eyimpembelelo entle kakhulu yokufunxa imathiriyeli.
4. Ukusebenza koomatshini:
I-aluminium foam isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo. Yimpahla yentsimbi emhlophe, ekhanyayo kunye nesilivere eneempawu ezibalaseleyo zokucutshungulwa lula. Iyakwazi ukuhlanjululwa, inqunywe, icwangciswe, igayiwe, njl., kwaye inokucutshungulwa ngokulula kwiiplate kunye nemicu. Iibhari kunye namalungu ahlukeneyo amile ngendlela ekhethekileyo.
5. Ukhuseleko lwendalo esingqongileyo:
I-Non-toxic: I-Aluminiyam i-foam yinto edibeneyo eyenziwe ngesinyithi kunye ne-pores, engeyiyo ityhefu kwaye ayiyi kusinda kwiigesi eziyityhefu kumaqondo aphezulu.
Inokuphinda isetyenziswe: Awona malungu aphambili ekhemikhali ye-aluminiyam igwebu ziingxubevange ze-aluminiyam kunye neeoksidi zazo, ezinokuthi zihlaziywe nge-100% ngaphandle kokubangela naluphi na ungcoliseko kokusingqongileyo.
I-electromagnetic shielding: I-electromagnetic shielding (ngaphantsi kwe-200MHz) ikhusela i-electromagnetic shielding 90dB, kunye nokusebenza okugqwesileyo kwe-electromagnetic shielding.
6. Iinkalo zesicelo semveliso
Ngenxa yeepropati zayo ezikhethekileyo, iimveliso ze-aluminium ze-foam zinokusetyenziswa ngokubanzi kwi-aerospace, i-aviation, i-high-speed train trains, izitimela zikaloliwe zasezidolophini, ukwakhiwa kweenqanawa, uloliwe ohamba ngesantya esiphezulu, ukwakhiwa, itonela kunye nezithintelo zesandi endleleni. ukothuka, ukufunxwa okuphezulu kwamandla empembelelo, ukusebenza okuphezulu kwe-electromagnetic ukukhusela ubushushu, ukumelana nobushushu obuphezulu, ukumelana nomlilo kunye nokungatsha. Inobuhlobo obukhethekileyo bokusingqongileyo.
Ukusebenza kwe-Damping: Ivavanywe yi-Institute of Solid State Physics, i-Chinese Academy yeSayensi, i-friction yangaphakathi ye-Q-1 ye-aluminium ye-foam ifikelela kwi-6 × 10-3.
