Nibo ni foomu nickel ti jade lati?

foomu nickeljẹ ohun elo ti a lo latiṣelọpọ awọn amọna batiri,ọna iṣelọpọ awọn ohun elo foomu nickel gbogbogbo jẹ: sponge polyurethane akọkọ, lẹhinna electrodeposition, ati nikẹhin sintering.

Ninu ilana yii, electroplating gbogbo lo kemikali plating, electroplating conductive alemora ati igbale plating awọn ọna mẹta; electrodeposition le ṣee lo imi-ọjọ tabi sulfamate nickel plating; Idi ti ilana sisọpọ ni lati sun kuro ni sponge polyurethane ni afẹfẹ ni afẹfẹ idinku hydrogen fun idinku idinku ti awọn ọna meji, ninu eyiti afẹfẹ fi iná pa polyurethane sponge nipa lilo ifoyina ti 300 ~ 700 ℃ decarburization; ni 800 ~ 1000 ℃ hydrogen atehinwa bugbamu fun 30 ~ 60 iṣẹju fun sintering idinku, awọn atehinwa bugbamu jije amonia jijẹ gaasi pẹlu kan jijẹ gaasi agbara ti 0.8 ~ 1.2 L / g (0.8 ~ 1.2 liters ti amonia decomposition gaasi fun giramu ti nickel) .

Ọna yii ni ibatan si ọna ti ngbaradi foomu nickel lati kanrinkan polyurethane nipasẹ iṣipopada,electrodeposition ati sintering, characterized ni wipe sintering igbese jẹ taara pyrolytic electrodeposition ti awọn foomu polyurethane ni a atehinwa bugbamu, ninu eyi ti awọn atehinwa bugbamu ti wa ni amonia jijẹ gaasi, awọn idinku otutu ni 400-1000 ° C, awọn idinku akoko jẹ 30-60 iṣẹju, ati awọn Lilo gaasi jijẹ jẹ 0.4-0.8 L / g. Gaasi jijẹ amonia (njẹ 0.4-0.8 L / g ti nickel fun giramu). 0.4-0.8 L ti gaasi jijẹ amonia) jẹ adalu nitrogen ati hydrogen pẹlu ipin iwọn didun ti 1: 3.

Awọn lenu siseto jẹ ninu awọn hydrogen idinku bugbamu, pẹlu electrodeposition tifoomu nickelti o ni awọn polyurethane sponge taara pyrolysis sintering, erogba ati hydrogen, Abajade ni gaseous hydrocarbons, gẹgẹ bi awọn CH4, C2H6, yi gasification ilana le ṣe awọn graphite ninu awọn la kọja ara ti awọn C regede yiyọ.
