Chigadzirwa blog

Kudzikira kwemafuta ezvicherwa uye kushushikana kuri kuramba kuchikura pamusoro pesimba uye nyaya dzezvakatipoteredza zvakakonzera kuyedza kwakadzama kwetsvakiridzo yekugadzira mamwe masimba emagetsi. Electrochemical electrolysis yemvura inoonekwa seanovimbisa zano rekugadzira mafuta ehydrogen.

Munguva yekuwedzera yakakomba isina waya kutaurirana uye kusvibiswa kwemagetsi, kudiwa kweanoshanda emagetsi mafungu ekutora zvinhu kwave kwakakosha kupfuura nakare kose. Metal foam, sechinhu chitsva, inoratidza kugona kukuru mundima iyi. Tsvagiridzo ichangoburwa yakanangana nekuongorora iyo electromagnetic wave absorption simba resimbi furo, uye mhedzisiro yacho inoshamisa.

Munzanga yemazuva ano, isu tinobvunza chinovharira chinonzwika chigadzirwa ichi chiri kuramba chichiwedzera, mashopu, zvipatara, zvikoro, mahofisi ekutungamira migwagwa, uye zvichingodaro kudiwa kwekudzikisa ruzha, mukuita kubvunza, mubvunzo unonyanya kubvunzwa ndewekuti: sei. zvakawanda izvi zvinogona kuderedzwa. Iye zvino tichagovana newe mutemo wekudzikisa ruzha weinzwi chipingamupinyi.

Aluminium foam ndeyepamusoro-inoshanda lightweight zvinhu, iyo inoshandiswa zvakanyanya mukugadzira mota, kushongedza kwekuvaka uye mamwe minda. Kuti ugadzire furo realuminium, unofanirwa kushandisa zvakatevedzana zvemidziyo, kusanganisira kugadzirisa, kupupa, kuomesa uye mamwe maitiro. Paunenge uchishandisa izvi zvishandiso, tarisa kuchengetedza, gadzirisa uye chengetedza zvishandiso zvinoenderana nemirairo kuti uve nechokwadi chekugadzirwa kwemhando uye kushanda zvakanaka kwealuminium foam.

Furo reAluminium rakafanana pachimiro nechiponji uye rinozivikanwa sesimbi yepasi rose, ine huremu hwakaderera uye huremu hwakareruka, hunoshandiswa sechidziviriro chemotokari dzemuchadenga, isingamiri pakutsikirirwa uye inokwanisa kumirisana nemwaranzi-indundundu dzemagetsi. Icho chinhu chitsva chesimbi chakagadzirwa nefoamed aluminium alloy.

Sezvinoshandiswa zvakanyanya simba-inotora zvinhu zvekudzivirira, kushandiswa kwealuminium foam sandwich (AFS) mapaneru anoramba akaomeserwa neiyo yakadzikira yakadzikira michina yefoam core. Iko kubatanidzwa kwecoppercoated kabhoni fibers (Cf) kwakaratidza kuve kunoshanda mukuvandudza michina yealuminium foam.

Asi, kunzwisiswa kwekuita kwayo kupupa uye microstructure kuchiri kushoma. Mune iri basa, AFS neCf/AFS dzakagadzirwa nenzira yekurongedzera rolling poda metallurgy. Hunhu hwekupupa hweAFS neCf/AFS panguva yetembiricha yakakwira yaive munzvimbo yakacherechedzwa uchishandisa synchrotron radiation X-ray imaging tekinoroji kuongorora mhedzisiro yeCf pabubble nucleation, kukura, uye kugadzikana kwefuro. Uyezve, iyo macroscopic pore saizi yekugovera, microscopic microstructure, uye compressive mechanical zvimiro zveAFS neCf/AFS zvakaongororwa. Mhedzisiro yacho yakaratidza kuti kuvepo kweCf kunowedzera zvakanyanya nucleation rate, kunonatsiridza kugadzikana kwekupupa, uye kunodzivirira kuumbwa kwemabhuru akakura akasarudzika panguva yekutanga nucleation nekukura. Zvichakadaro, Cf/AFS yakaratidza madhayamita akatsetseka epore uye mashoma mapore defects pane AFS. Kugoverwa kweCf nekunyorova kwakanakisa pamadziro epore kwakadzivirira kuputika kwefirimu remvura uye kuderedzwa kubatanidzwa. Kuedza kwekumanikidza kwakaratidza kuti, mukuenzanisa neAFS, simba rekumanikidza uye simba rekutora simba reCf / AFS rakawedzera neanenge 40.6% uye 84.8%, maererano.

Metal foam isimbi ine zvinhu zvakakosha, iyo ine simbi uye furo zvinhu, saka zita resimbi furo. Saka, furo resimbi isimbi here?

Unoziva aluminium foam here? Ichi chinyorwa chekuvandudza chiri kukonzera nyonganyonga mumaindasitiri akasiyana nekuda kwehuremu hwawo uye kuita zvinhu zvakasiyana-siyana. Mune ino blog, isu tichanyatso tarisisa mhando dzakasiyana dzealuminium foam uye tiongorore huwandu hwavo hwakawanda hwekushandisa.
