1. Izici zesipika:
Ukusebenza kokumuncwa komsindo: Ipuleti le-aluminium eliyigwebu elivaliwe lingafakwa imbobo ukuze lenze ibhodi lokumunca umsindo elinezinga eliphezulu lokumunca umsindo. Uma izinga lokuvula lingu-1%~3%, izinga lokumunca umsindo liphezulu kakhulu. Izinga lokumunca umsindo elikalwa ngendlela yegagasi elimile likububanzi obungu-1000Hz ukuya ku-2000Hz, futhi izinga lokumunca umsindo lifinyelela ku-40% kuya ku-80%.
Umthelela wokufakwa komsindo we-aluminium eyigwebu: ibhodi lokufakwa komsindo elenziwe ngephaneli yesamishi ye-aluminium eyigwebu, ugqinsi olungu-20mm, ukufakwa komsindo: 20 ~ 40dB.
2. Ukumelana nesimo sezulu:
Ukumelana nokugqwala: ukuchayeka emkhathini wasolwandle unyaka owodwa, akukho okungavamile okusobala; ngaphansi kwezimo zokugqwala ezisheshisiwe, ukuhlolwa kwesifutho sikasawoti esifuthoza amanzi akunakho okungavamile iminyaka emi-2; kukhombisa ukuthi ukumelana nokugqwala kwe-aluminium enegwebu kuhle kakhulu.
Akukho ukumuncwa komswakama: Izinga lokumunca umswakama we-aluminium enogwebu ngu-0.0%. Akukho ukumuncwa komswakama, futhi akukho ukuwohloka kokusebenza kwe-acoustic ngenxa yomswakama.
Izakhiwo ezikwazi ukumelana nokushisa/ezingashi: I-aluminium enegwebu ithambe ekushiseni okuphezulu okungu-600°C, futhi iyimpahla engashi.
Ukusebenza komshicileli: I-thermal conductivity ye-aluminium enegwebu ingu-0.25~0.62W/mK, okulingana naleyo yemabula, futhi inokusebenza okuhle kokuhlukanisa.
Ukuzinza kokushisa: I-coefficient enwetshiwe yomugqa ye-aluminium enegwebu ingu-1.934*10 ℃, okulingana nokhonkolo, futhi akulula ukukhubaza ukushisa.
3. Izakhiwo zemishini:
Izakhiwo zemishini: amandla okucindezela: 3 kuya ku-17 MPa; amandla e-flexural: 3 kuya ku-15 MPa; amandla okuqina: 2 kuya ku-7 MPa;
Ukusebenza okuqinisayo: Ukumuncwa kwamandla kungafinyelela ku-8J/cm3～30J/cm3, futhi i-aluminium enegwebu ingamunca amandla ngokuguqulwa, okuwumthelela omuhle kakhulu wokumunca amandla.
4. Ukusebenza komshini:
I-aluminium foam isetshenziswa kabanzi emikhakheni ehlukahlukene. Kuyimpahla yensimbi enezimbotshana, ekhanyayo nesiliva-emhlophe enezici ezinhle kakhulu zokucubungula kalula. Ingagawulwa, isikwe, ihlelwe, igaywe, njll., futhi ingacutshungulwa kalula ibe amapuleti nemicu. Amabha nezingxenye ezihlukahlukene ezimise okukhethekile.
5. Ukuvikelwa kwemvelo okuluhlaza:
Okungewona ubuthi: Igwebu le-Aluminium liyinhlanganisela yezinto ezakhiwe ngensimbi nezimbotshana, ezingenabo ubuthi futhi ezingeke zibalekele amagesi anobuthi emazingeni okushisa aphezulu.
Okusebenziseka Kabusha: Izingxenye zamakhemikhali eziyinhloko zegwebu le-aluminiyamu ama-alloys e-aluminium nama-oxides awo, angavuselelwa kabusha ngo-100% ngaphandle kokudala noma yikuphi ukungcoliswa kwemvelo.
I-Electromagnetic shieding: I-electromagnetic shielding (ngaphansi kuka-200MHz) ivikela i-electromagnetic shielding engu-90dB, nokusebenza okuhle kakhulu kokuvikela i-electromagnetic.
6. Izinkambu zesicelo somkhiqizo
Ngenxa yezakhiwo zayo ezikhethekile, imikhiqizo ye-aluminium Foam ingasetshenziswa kabanzi ku-aerospace, izindiza, izitimela ezihamba ngesivinini esikhulu, izitimela zesitimela zasemadolobheni, ukwakhiwa kwemikhumbi, isitimela esinesivinini esikhulu, ukwakhiwa, imigudu kanye nezithiyo zomsindo endleleni. ukushaqeka, ukumuncwa okuphezulu kwamandla omthelela, ukusebenza okuphezulu kokuvikela ugesi, ukwahlukanisa ukushisa okuhle kakhulu, ukumelana nezinga lokushisa eliphezulu, ukumelana nomlilo nokungashi. Inobungani bemvelo obuyingqayizivele.
Ukusebenza kwe-Damping: Ihlolwe yi-Institute of Solid State Physics, i-Chinese Academy of Sciences, isici sokungqubuzana sangaphakathi esingu-Q-1 se-aluminium ye-foam sifinyelela ku-6×10-3.
Isikhathi sokuthumela: Jun-02-2022
