Aluminium foam inowanikwa nekusanganisa aluminium alloy poda nechinhu chakaparadzaniswa panguva yekupisa uye gasification. Iine maitiro ehuremu huremu, yakakwirira porosity uye yakakwirira chaiyo nzvimbo. Iyo ine ese hunhu hwesimbi zvinhu uye furo, uye ine yakasimba mhedzisiro yekupikisa, yakakwirira chaiyo simba, yakakwirira tembiricha kuramba, yakasimba moto kuramba, uye zvakare ine yakasimba magetsi ekudzivirira uye kusefa zvinhu. Nhasi, tichasuma zvinomwe mashandiro ekuita kwealuminium foam yekuyedza zvakadzama.

1. Kuongororwa kwealuminium foam - structural performance analysis
Chimiro chikuru chechimiro chealuminium foam ndechekuti ine nhamba yakakura yepores mukati, iyo inoita kuti ireruke muhuremu uye yakakwirira mune chaiyo simba. Nekuda kweaya hunhu, aluminium foam inova yakanakisa sandwich filler yesandwich composite mapaneru, ayo anovandudza zvakanyanya deformation modhi yezvakaumbwa zvinhu zviri pasi pemutoro, kuitira kuti kupeta kwayo kuramba, kumanikidza simba, uye ruzha kugona kunovandudzwa. kubudirira kunobudirira. Zvichienzaniswa neyechinyakare sandwich material, iyo foamed aluminiyamu zvinhu zvinobudirira kuderedza mutengo uye kukunda kusakosha kweiyo anisotropy yehuchi sandwich zvinhu.

2. Kuonekwa kwealuminium foam material - kuongororwa kwekushanda kwekugadzirisa simba
Iyo maitiro kubva pakumanikidza kusvika pakudzvanywa kwefuro zvinhu yakakamurwa kuita nhanho nhatu, nhanho yekutanga ndeye elastic deformation nhanho. Mushure mekusimbiswa, mapores emukati eiyo foamed aluminiyamu zvinhu inodzoreredzwa elastic deformation. Nhanho yechipiri ndiyo nhanho yekuumba chikuva. Kana iyo mechanic simba reiyo foamed aluminium zvinhu inosvika padanho risingagoneke, inopinda padanho rekuumba deformation. Panguva ino, ma pores emukati anoita deformation senge kubereka uye kukambaira, uye pakupedzisira anodonha zvachose. Kana dhigirii rekudonha rasvika pakubata pakati pemadziro epore akatarisana, inopinda padanho rechitatu: densification nhanho. Naizvozvo, mushure mekunge furo realuminium raiswa pasi pekumanikidzwa, rinosangana neyakasiyana compression deformation maitiro. Mukuita, kudzvanywa kunoshandurwa kuve kugona kwefoam deformation, iyo inonyatso kutora simba resimba rekuita.

3. Kuonekwa kwealuminium foam - shock absorption performance analysis
Aruminiyamu yakafurwa ine yakakwira damping zvivakwa, 5 kusvika ka10 nguva yearuminiyamu yakachena. Hunhu uhu hune hukama ne porosity, pore size uye load-strain amplitude yealuminium furo pachayo. Iyo yakakwirira porosity, iyo diki saizi yepore uye yakakura iyo mutoro-strain amplitude, zviri nani kunyorovesa kwealuminium furo.

Kana iyo yakafukidzwa nealuminium zvinhu inoiswa pasi pekunetseka kwekunze, nekuda kwekusaenzana pores, iyo strain simba kugovera haina kuenzana, zvekuti yakajairika strain simba inoshandurwa kuita shear stress, iyo inopedza kushushikana kwekunze nekuishandura kuita inopisa simba mukati me. furo aruminiyamu zvinhu . Zvinoenderana nehunhu uhu hwehupfuro hwealuminium zvinhu, foamed aluminium zvinhu zvinova zvakanakisa zvekukatyamadza zvinhu. Zvakadai semabhampa emotokari, giya rekumhara rezvikepe, nezvimwe.

4. Aluminium foam test - sound absorption performance analysis
Iyo yakasarudzika pore chimiro chealuminium furo zvinhu inoita kuti ive yakanaka yekunyudza kuita. Kana ruzha rwapfuura nepapore, rwunokonzera kunzwika kweruzha mupore, uye kukwenya nemadziro epore kunoburitsa simba rekupisa, uye simba rekupisa rinobviswa kuburikidza nealuminium, saka chimiro chepore chearuminiyamu yakapupuma zvinhu zvinobudirira. inobata ruzha. Iko kunyudzwa kweruzha kuita kwefuro aluminium zvinhu kunowedzera nekuwedzera kweporosity, kudzikira kwesaizi yepore uye kuwedzera kwekukora kwezvinhu. Zvinoenderana neruzha rwekunyudza zvimiro zvealuminium foam, inoshandiswa zvakanyanya mumaredhiyo ekurekodha masitudiyo uye otomatiki hofisi michina.

5. Kuonekwa kwealuminium foam - kuongorora kwe electromagnetic shielding performance
Tsvagiridzo uye kuyedzwa kunoratidza kuti iyo foamed aluminium zvinhu ine yakanaka electromagnetic kudzivirira kuita. Kana iyo yakakwira-frequency magineti inopfuura nemufuro, eddy yazvino magineti inogadzirwa mukati mefuro, iyo inodzima iyo yekutanga magineti. Zvinoenderana nekuita uku, iyo foamed aluminium zvinhu inoiswa mukamuri yemidziyo yemagetsi nemidziyo yemagetsi,

Mukudzivirira zvinhu zvemagetsi midziyo.

6. Kuonekwa kwealuminium foam material - kuongororwa kwekuchinja kwekushisa uye kushandiswa kwekushisa kwekushisa
Nekuti iyo aruminiyamu furo zvinhu zvine huwandu hukuru hwemabhuru emhepo ane diki kupisa kugona, iyo yekupisa kwayo haina kukwirira seyealuminium, asi iri nani kupfuura iyo yemapurasitiki ane furo. Kupisa kwayo kunokonzerwa ne porosity, uye iyo yakakwirira porosity, iyo yakaipisisa yekupisa kwekushisa. Pasi pemamiriro ekunze ekugadzirisa, kupisa kunobviswa nekutsinhana kwekupisa pakati pegasi kana mvura uye madziro epore. Izvi zvinoita kuti aluminium furo ive yakanaka kupisa kupisa kana kupisa kupisa zvinhu. Semuenzaniso, mudziyo wekugadzira deicing unoiswa pamberi pebapiro rendege, uye gasi rinopisa kana antifreeze inoburitswa kubva mufuro realuminium zvinhu kuti zvizadzise chinangwa chekugadzira.

7. Aluminium foam kuonekwa - filtration performance analysis
Nekuda kwekupenya kwealuminium furo, inogona kushandiswa seyakanaka sefa zvinhu mubiological uye makemikari minda. Mapores ari mualuminium furo zvinhu ane yakanaka kusefa uye kupatsanura maitiro pamagasi kana zvinwiwa, uye anogona zvakare kusefa maomarara emhepo.
