Tsvagiridzo uye Kuvandudza Metal Foam

Tsvagiridzo uye Kuvandudza Metal Foam
Kuvandudzwa kwezvinhu zvitsva ndiyo kiyi yekuvandudza tekinoroji munguva nyowani, ichipa nzira nyowani yekuchengetedza zvakatipoteredza uye kuchengetedza simba, uye yakabatana zvakanyanya nehupfumi hwenyika uye zvemazuva ano. Zvigadzirwa zvesimbi zvine furo hazvisi chete zvine huremu huremu izvo zvakajairwa porous zvinhu, asi zvakare zvine yakanakisa mechaniki zvivakwa uye zvemuviri zvimiro zvakaita sekupisa nemagetsi, uye zviri nyore kuvandudza pane polymeric furo, kuwedzera mashandisirwo emhando yeporous zvinhu. Mumakore achangopfuura, kuvandudza tekinoroji nyowani kwakavandudza zvakanyanya kunaka kwesimbi yakafukidzwa, uye mamiriro ekushandiswa kwezvinhu zvitsva akachinjawo zvakanyanya. Vanhu vari kutanga kufarira kugadzirwa kwesimbi yakapupuma, kunyanya foamed aluminium alloy. Semuenzaniso: muindasitiri yemotokari, nekuda kwekuwedzera kwekuda kwekuchengetedza uye kuchengetedzwa kwezvakatipoteredza, vanhu vakatanga kufunga nezvekushandiswa kwesimbi yefoam.
Foam aluminium
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 kukamurwa 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 simbi furo yakakamurwa kuita yekunyungudusa furo nzira, hupfu hwekufuro nzira, kuwedzera hollow bhora nzira, uye sputtering nzira.
  • Kuburikidza ne-gomba foam simbi yakakamurwa kuita seepage casting nzira, mari yekukanda nzira, sintering nzira uye simbi yeplating nzira.
2. Zvinhu zvesimbi yefuro
Metal foams inoratidza zvimwe zvinonakidza zvimiro nekuda kwechimiro chavo cheporous, synthesizing zvimiro zvesimbi yepasi uye chimiro chayo.
Sechinhu chechimiro, iyo mechanic zvinhu zvesimbi furo inonyanya kutsamira pakuwanda 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 kunyudzwa kweruzha, kusefa, kupisa kupisa, kudzoreredza moto, kuderedza vibration, kunyorovesa, kukanganisa simba kunyura, uye electromagnetic kudzivirira.
Pakati pavo, iyo yakanyanya kudzidzwa uye yakashandiswa zvakanyanya ndiyo kutorwa 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 mumafekitari, 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.
