Igwebu le-nickel yinto esetshenziselwa ukwenza ama-electrode ebhethri. Ngokuvamile, indlela yokukhiqiza yezinto ze-nickel foam imi kanje: isiponji sokuqala se-polyurethane esisebenzayo, bese kuba yi-electrodeposition, futhi ekugcineni sintering.
Kule nqubo, i-electroplating ngokuvamile isebenzisa izindlela ezintathu: i-electroless plating, i-electroplating adhesive conductive kanye ne-vacuum plating; i-electrodeposition ingasebenzisa i-sulfate noma i-sulfamate nickel plating; inhloso yenqubo ye-sintering ukushisa isipontshi se-polyurethane emoyeni futhi sinciphise ku-hydrogen. Kunezindlela ezimbili zokunciphisa i-sintering emkhathini, lapho isiponji se-polyurethane sishiswa emoyeni ngokwelashwa kwe-oxidative decarburization ku-300 ~ 700 °C; i-sintering kanye nokunciphisa kwenziwa esimweni sokunciphisa ku-800 ~ 1000 °C ngaphansi komkhathi wokunciphisa i-hydrogen imizuzu engu-30~60, Umkhathi onciphisa igesi yokubola i-ammonia, futhi ukusetshenziswa kwegesi yokubola kungu-0.8~1.2 L/g (0.8) ~1.2 amalitha egesi yokubola ye-ammonia isetshenziswa igremu ngayinye yenikeli).
Le ndlela ihlobene nendlela yokulungiselela i-nickel enegwebu ngokuqhuba, i-electrodeposition kanye ne-sintering yesiponji se-polyurethane. Izinga lokushisa lokunciphisa lingu-400 ~ 1000℃, isikhathi sokunciphisa imizuzu engu-30 ~ 60, futhi ukusetshenziswa kwegesi yokubola kungu-0.4~0.8 L/g. Igesi yokubola i-ammonia (amalitha angu-0.4-0.8 egesi yokubola kwe-ammonia isetshenziswa igremu ngalinye le-nickel) iyingxube ye-nitrogen ne-hydrogen, futhi isilinganiso sayo somthamo ngu-1:3.
Indlela yokusabela iwukuthi emkhathini wokunciphisa i-hydrogen, igwebu le-nickel eliqukethe isipontshi se-polyurethane lifakwa i-pyrolyzed ngokuqondile futhi lifakwe i-electrodeposition, futhi ikhabhoni ne-hydrogen kusabela ukukhiqiza ama-hydrocarbon anegesi njenge-CH4 ne-C2H6. Le nqubo ye-gasification ingenza i-graphite emzimbeni we-porous. U-C uphuma ehlanzekile.
Igwebu le-nickel ligcinwa kanjani?
1. Sungula i-nickel foam ukuze unciphise ukusetshenziswa kwezinto ezingavuthiwe, ngevolumu enkulu nesisindo esincane, esidinga ukuvimbela umlilo, ukuvimbela amanzi, ukungena komoya kanye nezinye izidingo; sungula igumbi lokugcina amakhemikhali: linezici zezinhlobonhlobo eziningi, ukusetshenziswa okubanzi, izikhwama zepulasitiki ezinobufakazi bomswakama, ukungena komoya, njll.; sungula igumbi lokugcina amakhemikhali, impahla yensimbi: inkumbulo eyinhloko ye-metallic nickel
2. Inombolo yemikhiqizo yomugqa wokukhiqiza i-nickel enegwebu isethwe ngemva kwendawo ngayinye yokugcina. Ukuze kube lula ukucubungula, ukugcinwa kanye nokuzungezisa, ama-racks okugcina okukhiqiza emikhiqizo ekhethekile asethiwe.
3. Imikhiqizo ye-nickel foam yakhiwe izingxenye ezimbili: ingxenye yokuqala iwumkhiqizo oqediwe ngaphandle kokugunda, ogcinwa ngokuhlukana ukuze uvimbele ukungqubuzana nokukhipha. Lezi zingxenye ezimbili zigundwa ngokwezidingo zomsebenzisi womkhiqizo, futhi zimakwe ngokucacile ephaketheni. Isitoreji, ukupakisha, ukumelana nomswakama kanye nokumelana nengcindezi kuyahlangabezana nezindinganiso zehhotela.
