Igwebu lensimbi: Into entsha eyinsimbi “eqinile” futhi “engasindi”.

I-Metal Foam inesakhiwo esiyingqayizivele, esihlanganisa izici zensimbi kanye nezakhiwo ezisebenzayo zezinto ezinama-porous. Igwebu lensimbi lingelezinto zensimbi ezinama-porous, i-porosity yangaphakathi ingaba phezulu ku-90% noma ngaphezulu, ukwakheka kufana "negwebu" noma "ikhekheba lezinyosi", kuphula umqondo wendabuko wesakhiwo esiminyene sensimbi, zombili izici zensimbi "eziqinile". kanye nezici ze-bubble "zokukhanya", ukuhlanganiswa okusha kwesakhiwo-umsebenzi wezinto zensimbi. “Yephula umqondo wendabuko wesakhiwo esiminyene sensimbi futhi inazo zombili izici zensimbi nebhamuza, okuwuhlobo olusha lwempahla yensimbi enokuhlanganiswa komsebenzi wesakhiwo. Ngenxa yesakhiwo sayo esiyingqayizivele, i-foam metal ayigcini nje ngokugcina i-conductivity, i-ductility, i-weldability nezinye izici zensimbi eyisisekelo, kodwa futhi inezici ezisebenzayo zezinto ezinama-porous, njengokumuncwa kwamandla nokudlidliza, ukunciphisa umsindo, ukuvikela i-electromagnetic, ukungena komoya kanye nokungena kwamanzi, okuye kwaheha ukunaka okusabalele emkhakheni wesayensi yezinto zokwakha ekhaya naphesheya futhi isetshenziswa kabanzi ku-aerospace kanye ne-petrochemical. amasimu.

Izindlela eziyinhloko zokuhlukanisa i-foam yensimbi yilezi:
(1) Ngokusho kobukhulu bembotshana embotshana kanye nembobo: ububanzi bembotshana bungaphansi kuka-0.3mm, i-porosity ephakathi kuka-45% no-90%, eyaziwa ngokuthi insimbi enezimbotshana; futhi imbotshana ububanzi 0.5-6mm, porosity ezingaphezu kuka 90%, eyaziwa ngokuthi Foam metal;
(2) Ngokwesakhiwo se-pore: ihlukaniswe ngesakhiwo se-pore kanye nesakhiwo se-pore evaliwe;
(3) Ngokusho kwenqubo yokulungiselela: ekuqaleni okulungiselelwe indlela yokugwedla kubizwa ngokuthi igwebu lensimbi, futhi kamuva kwathuthukiswa ukukhishwa kwe-percolation nezinye izindlela zokulungiselela kubizwa nangokuthi i-ventilation metal;
(4) Ngokohlobo lwe-matrix: igwebu le-aluminium, igwebu le-nickel, igwebu lethusi nokunye. Inqubo yokulungiselela, indlela yendabuko yokulungiselela ukuthola igwebu lensimbi iyinkimbinkimbi kakhulu yesakhiwo sembotshana esingajwayelekile, futhi ukuphrinta kwe-3D kungalawula ngokunembile ukwakheka kwembotshana, ngokuya ngokunemba ukunika amandla igwebu lensimbi ukuze kwandiswe izimo zohlelo lokusebenza, njenge-titanium enezimbotshana. amathuluzi ezokwelapha, anembile kanye nezinye izinkambu zokugcwalisa izikhala zesicelo sensimbi yegwebu.

Impahla edidiyelwe yesakhiwo-esebenzayo, ithemba lesicelo segwebu lensimbi libanzi
I-Metal Foam ihlanganisa isakhiwo kanye nomsebenzi: njengento yesakhiwo, i-foam yensimbi inezici zesisindo sokukhanya namandla athile aphezulu; njengento esebenzayo, igwebu lensimbi linezinhlobonhlobo zezinto ezibonakalayo ezifana ne-porous, i-vibration damping, i-damping, i-sound-absorbing, i-soundproofing, i-heat dissipation, i-shock absorption, i-electromagnetic shielding nokunye. Ngezakhiwo zayo eziyingqayizivele, igwebu lensimbi lisetshenziswe kabanzi emikhakheni yezimboni nasezinkundleni zobuchwepheshe obuphezulu:
(1) Isebenzisa isisindo esilula kanye nezici ezithile zamandla aphezulu, isetshenziselwa ukwenza izinto ezisetshenziswayo zokuntanta amanzi, izinto zezemidlalo (njengezihlibhi, njll.), kanye nezingxenye ezihambisanayo zezimoto zasemkhathini;
(2) Ukusetshenziswa kwe-porous, nokukhiqizwa kwezihlungi zamakhemikhali, ukuhlanzwa kwamanzi asetshenziswa ku-gasification processor, ukugcwalisa okuzenzakalelayo kwama-bearings kawoyela, imihlobiso enamakha, njll.;
(3) ukusetshenziswa kwe-vibration damping, ukusebenza kwe-damping, nokukhiqizwa kwayo njengesivimbeli, isibambisi sokudlidliza, njengegiya lokuhlala likamkhumbi-mkhathi, amakhushini okuphepha okudluliswa kwekheshi kanye namabhokisi ahlukahlukene, ikakhulukazi amabhokisi ezokuthutha emoyeni, imibhede yamathuluzi omshini, izisekelo, izindandatho zokudambisa, njalonjalo;
(4) Ukusetshenziswa kwesivikelo sikazibuthe sikagesi, ukumuncwa komsindo okungasindi kanye okuhle kakhulu, izakhiwo zokuvala umsindo, kusetshenziswe ukwenza amaphaneli okuvikela umsindo embonini yezokwakha, igobolondo lezinsimbi zikagesi kanye nesakhiwo segumbi elivikela ugesi.

Ezintweni ezithile, i-foam yensimbi isetshenziswa kabanzi ku-aluminium, i-nickel, ithusi kanye nama-alloys ayo, izici eziyinhloko zezinto ezihlukahlukene ze-matrix kanye nezindawo zokufaka isicelo ziyahlukahluka.
(1) Igwebu le-Aluminium: Njengento yokuqala eyakhiwe ngensimbi eyigwebu, inzuzo enkulu yegwebu le-aluminium ilele esisindweni esilula, ukwahlukanisa ukushisa, ukwahlukanisa umsindo, ukuvikela i-electromagnetic, ukumuncwa kwamandla omthelela, njll., esetshenziswa kusendlalelo sokuvikela umthelela. imicibisholo ecitshwayo, izindiza nezingxenye zazo ezigaywe kabusha, futhi ibuye isetshenziswe emkhakheni we-buffer yezimoto, i-electronic and mechanical vibration damping device, i-electromagnetic wave. ikhava yokuvikela yokunikezwa kwamandla ku-pulse, njalonjalo;
(2) Igwebu le-nickel: nesakhiwo salo se-pore esixhunyiwe kanye ne-porosity ephezulu, igwebu le-nickel ekungeneni komoya okuphezulu, indawo ephezulu namandla e-capillary, kuyilapho ukumelana nokugqwala kunezinzuzo ezibalulekile, ezivame ukusetshenziswa ekukhiqizeni izihlungi zoketshezi, iziguquli ze-catalytic, ama-atomizer namapuleti e-electrode yebhethri kanye nezishintshi zokushisa;
(3) Igwebu lethusi: Igwebu lethusi linokusebenza okuhle kukagesi kanye ne-ductility, ekulungiseni izinto ze-electrode negative (inkampani yenethiwekhi), izithwali ze-catalyst nezinto zokuvikela kazibuthe kanye nezinye izici zamandla amakhulu.
