Ụfụ nickel bụ ihe eji arụpụta electrodes batrị. N'ozuzu, usoro mmepụta nke ihe nickel foam bụ nke a: sponge polyurethane nke mbụ na-eduzi, emesia electrodeposition, na n'ikpeazụ sintering.
Na usoro a, electroplating n'ozuzu nakweere ụzọ atọ: electroless plating, electroplating conductive nrapado na agụụ plating; electrodeposition nwere ike iji sulfate ma ọ bụ sulfamate nickel plating; Ebumnuche nke usoro nchikota bụ iji kpoo sponge polyurethane na ikuku ma belata ya na hydrogen. Enwere ụzọ abụọ maka mbelata mbelata nke ikuku, nke a na-akpọ sponge polyurethane na ikuku site na ọgwụgwọ decarburization oxidative na 300 ~ 700 Celsius; sintering na Mbelata na-rụrụ na a mbenata ikuku na 800 ~ 1000 Celsius C n'okpuru hydrogen mbenata ikuku maka 30 ~ 60 nkeji, The mbenata ikuku bụ amonia decomposition gas, na oriri nke decomposition gas bụ 0.8 ~ 1.2 L / g (0.8). ~ 1.2 lita nke amonia decomposition gas na-eri kwa gram nke nickel).
Usoro a metụtara usoro maka ịkwadebe nickel foamed site na-eduzi, electrodeposition na sintering nke polyurethane sponge. The Mbelata okpomọkụ bụ 400 ~ 1000 ℃, Mbelata oge bụ 30 ~ 60 nkeji, na oriri nke decomposition gas bụ 0.4 ~ 0.8 L / g. Amonia decomposition gas (0.4-0.8 lita nke amonia decomposition gas na-eri kwa gram nke nickel) bụ ngwakọta nke nitrogen na hydrogen, na oke olu ya bụ 1: 3.
Usoro mmeghachi omume bụ na n'ime ikuku na-ebelata ikuku hydrogen, ụfụfụ nickel nwere sponge polyurethane bụ pyrolyzed ozugbo ma mee ya site na electrodeposition, na carbon na hydrogen na-emeghachi omume iji mepụta hydrocarbons gas dị ka CH4 na C2H6. Usoro gasification a nwere ike ime ka graphite dị n'ime ahụ porous. C na-apụta dị ọcha.
Kedu otu esi echekwa ụfụfụ nickel?
1. Mepụta ụfụfụ nickel iji belata oriri nke akụrụngwa, na nnukwu olu na ịdị arọ dị arọ, chọrọ mgbochi ọkụ, mkpuchi mmiri, ventilashion na ihe ndị ọzọ a chọrọ; guzobe ụlọ nchekwa kemịkalụ: ọ nwere njirimara nke ọtụtụ ụdị, ojiji sara mbara, akpa rọba mmiri na-egosi mmiri, ikuku ikuku, wdg; guzobe ụlọ nchekwa kemịkalụ, ihe ọla: isi ebe nchekwa nke nickel dara
2. Ọnụ ọgụgụ nke ngwaahịa nke eriri mmepụta nickel foamed ka edobere ebe nchekwa ọ bụla. Iji mee ka nhazi, nchekwa na ntụgharị aka, a na-edobe akwa nchekwa mmepụta maka ngwaahịa pụrụ iche.
3. Ngwa nickel foam bụ akụkụ abụọ mejupụtara: akụkụ nke mbụ bụ ngwaahịa emechara na-enweghị ịkwa akwa, nke echekwara iche iche iji gbochie nkukota na extrusion. A na-akpụcha akụkụ abụọ a dị ka mkpa nke onye ọrụ nke ngwaahịa ahụ si dị, ma na-akara ya nke ọma na ngwugwu. Nchekwa, nkwakọ ngwaahịa, mmiri na-egbochi mmiri na nrụgide na-agbaso ụkpụrụ ụlọ nkwari akụ.
