Ko te pahuka nika he rauemi hei hanga i nga hiko hiko. Ko te tikanga, ko te tikanga whakangao o nga rauemi nickel foam e whai ake nei: te hautai polyurethane conductive tuatahi, katahi te electrodeposition, ka mutu te sintering.
I roto i tenei tukanga, electroplating tikanga tango toru tikanga: whakakikorua electroless, electroplating whakapiringa conductive me te korehau whakakikorua; Ka taea e te electrodeposition te whakamahi i te whakakikorua nickel sulfate, sulfamate ranei; ko te kaupapa o te mahi whakangao he tahu i te hautai polyurethane ki te hau ka whakaiti i te hauwai. E rua nga tikanga mo te whakaheke i te whakaheke i roto i te haurangi, kei te tahuna te hautai polyurethane i te rangi ma te maimoatanga decarburization oxidative i te 300 ~ 700 °C; Ko te whakaheke me te whakaheke ka mahia i roto i te haurangi whakaheke i te 800 ~ 1000 °C i raro i te hauwai whakaheke hauwai mo te 30 ~ 60 meneti, Ko te hau whakaheke he haukini haukini haukini, me te kohi o te hau pirau ko 0.8 ~ 1.2 L / g (0.8). ~1.2 rita o te haukinia pirau haukini ka pau mo ia karamu o te nickel).
Ko te tikanga e pa ana ki tetahi tikanga mo te whakarite i te nickel pahuka ma te whakahaere, te electrodeposition me te sintering o te hautai polyurethane. Ko te pāmahana whakaheke ko 400 ~ 1000 ℃, ko te wa whakaheke ko te 30 ~ 60 meneti, me te kohi o te hau pirau ko 0.4 ~ 0.8 L / g. Ko te hau o te haukinia (0.4-0.8 rita o te haukini haukini ka pau mo ia karamu o te nickel) he ranunga o te hauota me te hauwai, a ko te 1:3 te owehenga rōrahi.
Ko te tikanga tauhohenga kei roto i te hauwai whakaheke hauwai, ko te nickel foam kei roto i te hautai polyurethane e tika ana te pyrolyzed ka sintered e te electrodeposition, a ka tauhohe te waro me te hauwai ki te whakaputa waiwaro hau penei i te CH4 me C2H6. Ka taea e tenei tukanga whakaahuru te hanga i te kauwhata i roto i te tinana maiengi. Ka puta mai a C ki te horoi.
Me pehea te penapena pahuka nika?
1. Whakaritehia te pahuka nika hei whakaiti i te kai o nga rawa mata, me te nui o te rahi me te taumaha marama, me te aukati i te ahi, te parewai, te hau me etahi atu whakaritenga; whakapumau i te ruma rokiroki matū: he maha nga momo momo, he whakamahinga whanui, he peeke kirihou makuku-tohu, hau, aha atu; whakapumau ruma rokiroki matū , rauemi whakarewa: te mahara matua o te nickel konganuku
2. Ko te maha o nga hua o te raina hanga nickel pahuka i muri i ia waahi rokiroki. Hei whakahaere i te tukatuka, te rokiroki me te hurihanga, kua whakaritea nga whatanga rokiroki whakaputa mo nga hua motuhake.
3. E rua nga wahanga o nga hua pahuka nika: ko te waahanga tuatahi he hua kua oti te kore he kutikuti, he mea rongoa motuhake hei aukati i te tukinga me te tangohanga. Ko enei waahanga e rua ka kutikuti kia rite ki nga hiahia o te kaiwhakamahi o te hua, ka tino tohuhia ki runga i te kete. Ko te rokiroki, te takai, te makuku me te pehanga ka tutuki ki nga paerewa hotera.
