I-nickel foam yinto ephawulekayo eye yafumana ingqwalasela ebanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo. Esi sixhobo se-porous kunye ne-conductive sibonakalise ukuba sixabiseke kakhulu kwiinkalo ezininzi, ukusuka ekugcinweni kwamandla kunye nokuguqulwa kwi-filtration kunye ne-catalysis. Kule bhlog, siza kuphonononga ilizwe elinika umdla le-nickel foam kunye namandla alo okuguqula iitekhnoloji ezininzi.

Eli phepha lishwankathela iimpawu ezigqwesileyo zesinyithi sogwebu kunye neenkcukacha zeziphumo zophuhliso lwangoku lwesinyithi sogwebu, ngakumbi i-titanium foam, njengezinto ezixhathisayo kwi-aerospace, izixhobo ze-biomedical, izixhobo zokucoca ubushushu obuphezulu kunye nezixhobo zebhetri, njl. iindawo eziza kuphuhliswa.

I-Aluminiyam i-foam yokongeza izongezo kwi-aluminiyam ecocekileyo okanye iprofayili ye-aluminium, emva kokuba igwebu, ukongeza ekuthatheni ingqalelo iimpawu zezixhobo zetsimbi kunye namaqamza. Inoxinano oluphantsi, ukumelana nefuthe eliphezulu, ukumelana nobushushu, ukhuseleko lomlilo, ukuxhathisa umhlwa, ukugquma kwesandi, ukuguquguquka okuphantsi kwe-thermal, izinto ezilungileyo zokukhusela imagnethi, ukuxhathisa okunamandla, ukuhluza amandla, kulula ukwenza, ukuyifaka lula, ukubumba okuchanekileyo, kunye inokuqhutyelwa kumphezulu wepeyinti.

I-nickel foam yimathiriyeli ye-foam evuzayo kakhulu, ephantsi, ene-dimensional-dimensional ye-3-dimensional reticulated, into entsha nekhula ngokukhawuleza kwizinto zangoku zesayensi. Ulwakhiwo lwe-foam lunika isinyithi se-nickel i-open-cell structure, esinika ukugqithisela okugqwesileyo kunye nokugqithiswa kobushushu okubalulekileyo kunye neempawu zokulahla.
I-foam ye-nickel yenziwe nge-electroplating kwi-skeleton yeepolymers ezikhethekileyo kunye nesakhiwo sothungelwano esine-ntathu-dimensional, njenge-polyurethane, i-polyester polyurethane kunye nezinye iipolymers ezikhethekileyo (iziponji). Emva kokufakwa, imveliso yokugqibela ye-foam yesinyithi yenziwa ngokutshisa i-polymer yangaphakathi kunye nokunciphisa i-oxides yesinyithi, kwaye ibunjwe ngoomatshini ngonyango lobushushu beekhemikhali.
I-nickel foam, kunye neempawu zayo ezilula kunye nezixhobo zombane, yenye yezona zinto zibalulekileyo zokwakha i-AEM's hydrogen electrolyzers, ebonelela ngesisombululo esifanelekileyo sokuvelisa i-hydrogen esebenzayo kunye nezinzileyo.

Umahluko ophambili phakathi kweepaneli ze-aluminium foam kunye ne-aluminium veneer zizinto zabo, ubukhulu, ubunzima, amandla, ukumelana nomlilo, kunye noluhlu lokusetyenziswa.

Amagwebu esinyithi atsala ingqalelo kwizicelo zobunjineli ngenxa yokuxinana kwabo, ubungakanani bomthamo ophezulu kunye nokuhanjiswa kwe-thermal ephezulu. Kwishishini lokufudumeza kunye nokupholisa, i-compact heat exchangers, izibonelelo ze-thermal zelanga kunye nokugcinwa kwamandla e-thermal zikhokelo ezi-3 eziphambili.

I-nickel foam yinto egqwesileyo yokufunxa isandi kunye ne-coefficient ephezulu yokufunxa kwi-frequencies ephezulu; ukusebenza kwayo okufunxa isandi kwizandi eziphantsi kunokuphuculwa ngokuyilwa kolwakhiwo olufunxa isandi. I-nickel foam yenye yezona zinto zibalaseleyo ze-electrode kwiibhetri ze-cadmium-nickel kunye neebhetri ze-hydrogen-nickel. I-nickel foam ngokwayo ineempawu ezininzi ezintle.

igwebu lesinyithi zilungiswa ngokuntywila, i-electroplating, i-pressure casting, kunye neendlela zokugwaza. Phakathi kwabo, indlela ye-electroplating kunye ne-powder metallurgy method phantsi kokwahlula-hlulwa kwendlela yokugaya i-foaming ixhaphakile. Eyangaphambili ngokudibanisa i-agent ekhupha ugwebu kwintsimbi etyhidiweyo ukuvelisa i-foam yesinyithi; umva ngenkqubo ye-electrodeposition kwi-polyurethane foam skeleton ikhutshelwe kwi-foam yesinyithi. Okwangoku, i-foam yensimbi isetyenziswe ngokubanzi kwi-nickel ye-aluminium, ubhedu kunye ne-alloys yayo, ngaphezu kwesinyithi, i-magnesium, i-titanium, isinyithi, i-load kunye nokunye kunye nendawo ethile yesicelo.

I-Metal foam yimpahla yensimbi eneempawu ezikhethekileyo, ezinezinto zombini zetsimbi kunye ne-foam, ngoko ke igama lesinyithi se-foam. Ngoko, ngaba i-foam yensimbi yintsimbi?
Impendulo nguewe. I-foam ye-Metal yenziwe ngezinto zetsimbi, ezineempawu zetsimbi ezifana ne-conductivity yombane, i-thermal conductivity, amandla kunye nokunye. Ngelo xesha, i-foam yensimbi inenani elikhulu lee-pores ezincinci ngaphakathi, ezenza isakhiwo esifana ne-foam, esenza ukuba i-foam yensimbi ibe neempawu zobunzima bokukhanya, amandla athile aphezulu, ukufudumala kakuhle ukufudumala kunye nokunye.

I-foam ye-Metal inesakhiwo esiyingqayizivele, idibanisa iimpawu zetsimbi kunye neempawu ezisebenzayo zezixhobo ze-porous. I-Metal foam iyinxalenye yezixhobo zetsimbi ezinamaqhekeza, i-porosity yangaphakathi inokuba phezulu ukuya kuma-90% okanye ngaphezulu, imilo ifana ne "foam" okanye "i-honeycomb", iphula ingcamango yendabuko yesakhiwo esixineneyo sesinyithi, zombini iimpawu zetsimbi "ezomeleleyo". kunye neempawu ze-bubble "zokukhanya", ludibaniso olutsha lwesakhiwo-umsebenzi wezinto zetsimbi. “Yaphula ingqikelelo yemveli yolwakhiwo olushinyeneyo lwesinyithi kwaye ineempawu zentsimbi kunye neqamza, oluluhlobo olutsha lwemathiriyeli yentsimbi enokuhlanganiswa komsebenzi wesakhiwo.
