Aluminium foam (iyo porous simbi yakavakirwa paaluminium uye alloys ayo) yave ichizivikanwa kweanopfuura hafu yezana ramakore, asi ichine kugovera kudiki uye kushandiswa. Chikonzero chikuru cheizvi chaive kuderera kuberekana kwechimiro uye zvinhu zvemukati mukugadzirwa kwemafuro ealuminium. Kuvandudzwa kwealuminium foam tekinoroji kwaita kuti zvikwanise kukunda mamwe ematambudziko aya. Nzira dzakasiyana-siyana dzekugadzirwa kwesimbi dzakagadzirwa uye dzakaongororwa.

Pakutanga, vagadziri vezvinhu zvakadaro vakafemerwa nezvinhu zvakasikwa porous sehuni, pfupa, koral, pumice uye mamwe mamwe maminerari ane porous. Chinhu chakajairika chezvishandiso izvi ndiko kusanganiswa kwesimba rakawanda, huremu hwakaderera uye kutorwa kwesimba kwakanaka. Mazuvano, vagadziri vealuminium furo vanogona kugadzira simbi dzine zvinhu zvakafanana zviri nyore. Huwandu hwemashandisirwo emafuro ealuminium ikozvino hwawedzera kuwanda uye hune akawanda akasiyana ekushandisa.

Chinhu chakasiyana-siyana chine dhizaini isingaverengeki uye mashandisirwo ekuvaka. Zvakare chitarisiko chayo chakasiyana, ine inonzwika inonwisa zvivakwa zvichiita kuti ive yakanakira maapplication anoda ese ari maviri kutorwa uye runako. Inoshandiswa kuFacades, kuvharika kwemadziro, sirin'i mataira kana kudonhedza sirin'i, maresitorendi, mabara, mahofisi, zvivakwa zvemafurati, showroom kuratidza, Terrazzo pasi, signage, zvigadziriso zvemwenje, zviratidziro, uye chero application yaungafunga kufungidzira.

Aluminium foam inogadzira mapaneru akasimba asi asina kuremerwa. Kufanana nechitarisiko chechiponji chesimbi, inoratidzika inoshamisa, ine chimiro chemazuva ano chinoshamisa. Nezvekuvaka, furo realuminium rinogadzirwa mumapanera akasiyana-siyana, uye muhukobvu kubva pa12.7mm kusvika 43.2 mm (tsika iripo yakamirira huwandu). Mavhezheni akajairwa madiki, Pakati uye Makuru.

Iyo yepamusoro yepaneru yega yega inosiiwa muchimiro chayo chakasimba chakasikwa sezvakagadzirwa, kana kuti chinoitwa pamusoro pekugadzirira izvo zvinopa akawanda akasiyana kutaridzika. Kutaridzika sechinhu chakasimba "inopenya" inotarisa kune inoshanduka "mvura froth" kutarisa, kunyange tsika dzakagadzirwa. Mativi maviri epaneru yega yega, akaonekwa se 'pamusoro uye/kana pasi, anotaridzika zvakasiyana kubva kune mumwe nemumwe.

Kugadzirwa kwealuminium foam

Kune nzira dzakasiyana dzekugadzira aluminium foams.

Mune imwe nguva, furo resimbi rinowanikwa kubva musimbi yakanyungudutswa nenzira dzakasiyana. Sezvo aruminiyamu inotonhora nekuoma, furo resimbi rinogadzikana. Hova dzegasi kana mhepo dzinofuridza dzinoshandiswa kugadzira furo. Mhepo inoputika inoora pasi pemamwe mamiriro uye inoguma nekubuda kwegasi. Special additives dzimwe nguva inoshandiswa kudzikamisa mabubbles egasi kuitira kuti furo risaparare risati rapora. Iyi nzira inogona kushandiswa kuwana aluminium foam sheets, zvigadzirwa zvine maumbirwo akareruka uye aluminium furo masangweji. Zvigadzirwa zvakadaro zvine furo resimbi semusimboti, iro rakafukidzwa mativi ese ane layer yealuminium yakasimba.

Imwe nzira ndeyekukanda nekuzadza. Semuenzaniso, tsanga dzemunyu dzinogona kuita semazadza, ayo anobva asukwa kubva mualuminium matrix, uye pores anoonekwa panzvimbo yemunyu. Polyurethane foam ine tembiricha inodzivirira coating inoshandiswawo sechinhu chekuzadza, icho chinopisa panguva yekupisa kupisa.

Imwe nzira yekugadzira yealuminium foam inoshandisa hollow ceramic kana simbi mabhora, ayo anoiswa mukati mesimbi matrix.

Mukugadzira jekiseni, polymer granules inogona kushandiswa kugadzira pores. Nekuda kwenguva pfupi kwazvo yekuita, aya granules haaparare pasi pesimba rekupisa kwakanyanya. Ivo vanogona kuramba vari musimbi matrix semazadza kana kubviswa nekureba kupisa kurapwa. Muchiitiko chekupedzisira, yakavhurika-pored aluminium foam inowanikwa.

Kugadzirwa kwemafuro esimbi kuchine gwara rimwe chete, simbi yehupfu. Kutanga, musanganiswa wealuminium poda ine zvakakosha zvinowedzera inogadzirwa. Kana musanganiswa wakadaro uchipisa, furo uye sintering maitiro anoitika izvo, mushure mekutonhora, zvinoguma nemamwe marudzi ealuminium furo.

Nzira yemazuva ano yekuwana porous simbi ndeyekuwedzera tekinoroji. Nekuwedzera kwekugadzira, chimiro uye 3D chimiro chechikamu chinogona kudzorwa chaizvo. Nekudaro, maitiro aya achiri kudhura zvakanyanya uye anogona kungoiswa kune shoma nhamba yesimbi.

Properties uye kushandiswa

Yakavharwa-pore aluminium furo ine porosity ye80 kusvika 98%. Simba rayo rinopfuura zvakanyanya resimbi yakasimba yehuremu hwakafanana. Kushandiswa kwezvinhu zvakadaro kune simba guru, kunyanya kune nzira dzekufambisa dzemotokari yemotokari, indasitiri yezvemhepo uye kuvaka ngarava. Kuderedza uremu kunotungamirira kukuchengetedza mafuta kana kuita kuti zvikwanise kuwedzera uremu hwemutoro unotakurwa.

Iyo porous chimiro chealuminium furo inotora simba rekuita. Ichi chivakwa chinogona kushandiswa panguva yekufambisa kudzivirira kubva mukubonderana, sechidziviriro chezvombo uye kuputika. Metal furo rinoderedza ruzha. Naizvozvo, aluminium foam mapaneru anogona kushandiswa semadziro ekunyudza mutsindo mumigwagwa uye njanji. Kuvharisa ruzha mumabhaisikopo nehoro dzemakonzati kunogonawo kushanda. Nekuda kwehuremu hwayo hwakadzikira uye yakanaka nzvimbo, furo realuminium rinoshandiswa mukati nekunze dhizaini.
