Tsvagiridzo uye Kuvandudza Metal Foam

Tsvagiridzo uye Kuvandudza Metal Foam
Kugadziriswa kwezvinhu zvitsva ndiyo kiyi yekuvandudza tekinoroji munguva nyowani, ichipa nzira nyowani yekuchengetedza zvakatipoteredza uye kuchengetedza simba, uye yakabatana zvakanyanya nehupfumi hwenyika uye zvechimanjemanje.Zvigadzirwa zvesimbi zvine furo hazvisi chete zvine huremu huremu izvo zvakajairwa porous zvinhu, asi zvakare zvine zvakanakisa zvemichina zvimiro uye zvemuviri zvimiro zvakaita sekupisa nemagetsi, uye zviri nyore kuvandudza pane polymeric furo, kuwedzera mashandisirwo emhando yezvigadzirwa zveporous.Mumakore achangopfuura, kuvandudza tekinoroji nyowani kwakavandudza zvakanyanya kunaka kwesimbi yakapupuma, uye mamiriro ekushandisa ezvigadzirwa zvitsva akachinjawo zvakanyanya.Vanhu vari kutanga kufarira kugadzirwa kwesimbi yakapupuma, kunyanya foamed aluminum alloy.Semuenzaniso: muindasitiri yemotokari, nekuda kwekuwedzera kwekuda kwekuchengetedza uye kuchengetedzwa kwezvakatipoteredza, vanhu vakatanga kufunga nezvekushandiswa kwesimbi yefoam.

1. Kugadzirira nzira uye kukura kwesimbi furo
Iyo nzira yekugadzirira yemafuro esimbi inofemerwa nekugadziriswa kwepolymeric foam uye yakagadziridzwa zvakare nekuda kweiyo yakasarudzika simbi zvimiro.Metal foams inogona kupatsanurwa kuita mhando mbiri: kuburikidza-sero uye yakavharwa-sero zvinoenderana nekwavo yemukati pore chimiro.Nzira dzekugadzirira dzinogona kupfupikiswa sezvinotevera:
Metal foam yakakamurwa kuva:
  • Iyo yakavharwa-sero furo resimbi rakakamurwa kuita yekunyungudusa furo nzira, hupfu hwekufuro nzira, kuwedzera hollow bhora nzira, uye sputtering nzira.
  • Kuburikidza ne-gomba furo simbi yakakamurwa kuita seepage casting nzira, investimendi yekukanda nzira, sintering nzira uye simbi yeplating nzira.
2. Zvinhu zvesimbi yefuro
Metal foams inoratidza zvimwe zvinonakidza zvimiro nekuda kweiyo porous chimiro, synthesizing zvimiro zve base simbi uye chimiro chayo.
Sechinhu chechimiro, ma mechanic properties yesimbi furo inonyanya kuenderana nekuwanda kwayo uye zvimiro zvesimbi yepasi.Semuyenzaniso, furo resimbi rine high density zvakare rine high compressive simba, uye simbi furo ine high matrix simba zvakare ine high compressive simba.
Sechinhu chinoshanda, chine zvinhu zvakasiyana-siyana zvemuviri senge kupfekwa kweruzha, kusefa, kudzivirira kupisa, kudzoreredza murazvo, kuderedza vibration, kunyorova, kunyura kwesimba, uye electromagnetic kudzivirira.
Pakati pavo, iyo inonyanya kudzidzwa uye yakashandiswa zvakanyanya ndeyekutorwa kwesimba kwesimbi foam.
3. Kushandiswa kwesimbi yefoam
Iko kushandiswa kunoenderana nekuita, uye kuita kwakanakisa kwesimbi yefuro kunotarisa huwandu hwayo hwekushandisa.
Parizvino, zvimwe zvinhu zvefoam metal zvakashandiswa muJapan.Semuyenzaniso, iwo mafekitori anobvisa ruzha-anobata zvimiro zvealuminium furo anoshandiswa mumakamuri ekugadzira magetsi ezvitima zvekuona zveHokkaido nemidziyo yekuderedza ruzha mumafekitori, zvigaro zvechitima zveJR Shinkansen zvinoshandisa chimiro chakaumbwa chealuminium furo, uye yakasarudzika yekushongedza zvimiro zve. furo pamusoro rinoshandiswawo muzvivakwa.Indasitiri.
Kuburikidza ne-pore simbi mafuro anoshandiswa sesefa zvinhu, zvinopisa kupisa, mafirita uye zvinotsigira zvinotsigira, uye zvakare anoshandiswa se electrode zvinhu.
