Nickel foam chinhu chinoshandiswa kugadzira mabheti emagetsi. Kazhinji, nzira yekugadzira nickel furo zvinhu zvinotevera: kutanga conductive polyurethane chipanje, ipapo electrodeposition, uye pakupedzisira sintering.
Mukuita uku, electroplating inowanzotora nzira nhatu: electroless plating, electroplating conductive adhesive uye vacuum plating; electrodeposition inogona kushandisa sulfate kana sulfamate nickel plating; chinangwa chekugadzira sintering ndechekupisa siponji ye polyurethane mumhepo uye kuideredza mu hydrogen. Kune nzira mbiri dzekudzikisa sintering mumhepo, umo siponji ye polyurethane inopiswa mumhepo ne oxidative decarburization kurapwa pa 300 ~ 700 ° C; sintering uye kuderedza kunoitwa mumhepo inoderedza pa800 ~ 1000 °C pasi pe hydrogen inoderedza mamiriro emhepo kwemaminitsi makumi matatu kusvika makumi matanhatu, Mhepo inoderedza iammonia yekuora gasi, uye kushandiswa kwegasi rekuora i0.8 ~ 1.2 L/g (0.8) ~ 1.2 malita eammonia decomposition gasi inopedzwa pagiramu re nickel).
Iyo nzira ine chekuita nenzira yekugadzira furo nickel nekuitisa, electrodeposition uye sintering ye polyurethane sponge. Iyo tembiricha yekudzikisa i400 ~ 1000 ℃, nguva yekudzikisa i30 ~ 60 maminetsi, uye kushandiswa kwegasi rekuora i0.4 ~ 0.8 L/g. Iyo ammonia decomposition gas (0.4-0.8 litres of ammonia decomposition gas inopedzwa pagiramu renickel) musanganiswa wenitrogen nehydrogen, uye huwandu hwayo hunosvika 1:3.
Maitiro ekuita ndeokuti mumhepo inoderedza haidrojeni, furo re nickel rine polyurethane sponge rinonatswa pyrolyzed uye sintered ne electrodeposition, uye kabhoni nehaidhirojeni zvinobata kuburitsa gaseous hydrocarbons seCH4 neC2H6. Iyi gasification maitiro anogona kuita iyo graphite mumuviri une porous. C inobuda yakachena.
Nickel foam inochengetwa sei?
1. Gadzira nickel foam kuderedza kushandiswa kwezvinhu zvakasvibirira, nehuwandu hukuru uye huremu huremu, hunoda kudzivirira moto, kudzivirira mvura, kupinza mhepo nezvimwe zvinodiwa; gadza imba yekuchengetera makemikari: ine hunhu hwemhando dzakawanda, kushandiswa kwakakura, mabhegi epurasitiki hunyoro-uchapupu, kufefetedza, nezvimwe; gadza imba yekuchengetera makemikari, simbi zvinhu: iyo huru yekuyeuka yesimbi nickel
2. Nhamba yezvigadzirwa zvefoamed nickel production line inoiswa mushure meimwe nzvimbo yekuchengetedza. Kuti ufambise kugadzirisa, kuchengetedza uye kutenderera, mareki ekuchengetedza ekugadzira ezvigadzirwa zvakakosha anoiswa.
3. Zvigadzirwa zveNickel foam zvinoumbwa nezvikamu zviviri: chikamu chekutanga chigadzirwa chakapedzwa chisina kuveura, chinochengetwa zvakasiyana kudzivirira kudhumhana uye extrusion. Zvikamu zviviri izvi zvinogerwa zvinoenderana nezvinodiwa nemushandisi wechigadzirwa, uye zvakanyatsoiswa chiratidzo pasuru. Kuchengeta, kurongedza, hunyoro-uchapupu uye kusagadzikana-inoshingirira zvinosangana nezviyero zvehotera.
