Kumfa nickel abu ne da ake amfani da shi don kera na'urorin baturi. Gabaɗaya, hanyar masana'anta na kayan kumfa nickel shine kamar haka: soso na farko na polyurethane, sa'an nan electrodeposition, kuma a ƙarshe sintering.
A cikin wannan tsari, electroplating gabaɗaya yana ɗaukar hanyoyi uku: plating mara amfani, electroplating conductive m da vacuum plating; electrodeposition na iya amfani da sulfate ko sulfamate nickel plating; Manufar tsarin sintiri shine don ƙone soso na polyurethane a cikin iska kuma a rage shi a cikin hydrogen. Akwai hanyoyi guda biyu don rage raguwa a cikin yanayi, wanda aka ƙone soso na polyurethane a cikin iska ta hanyar maganin decarburization na oxidative a 300 ~ 700 ° C; sintering da raguwa ana za'ayi a cikin wani rage yanayi a 800 ~ 1000 ° C a karkashin wani hydrogen rage yanayi na 30 ~ 60 minutes, The rage yanayi ne ammonia bazuwar gas, da kuma amfani da bazuwar gas ne 0.8 ~ 1.2 L / g (0.8). Ana cinye lita 1.2 na iskar ammonia a kowace gram na nickel).
Hanyar tana da alaƙa da hanya don shirya nickel mai kumfa ta hanyar gudanarwa, electrodeposition da sintering na soso na polyurethane. The rage zafin jiki ne 400 ~ 1000 ℃, da rage lokaci ne 30 ~ 60 minutes, da kuma amfani da bazuwar gas ne 0.4 ~ 0.8 L / g. Ammoniya bazuwar gas (0.4-0.8 lita na ammoniya bazuwar iskar gas da ake cinye kowace gram na nickel) cakude ne na nitrogen da hydrogen, da girma rabo ne 1:3.
Hanyar amsawa ita ce, a cikin yanayin rage hydrogen, kumfa nickel mai dauke da soso na polyurethane yana pyrolyzed kai tsaye kuma an haɗa shi ta hanyar electrodeposition, kuma carbon da hydrogen suna amsawa don samar da iskar gas kamar CH4 da C2H6. Wannan tsari na gasification na iya yin graphite a cikin jiki mara kyau. C ya fito da tsabta.
Yaya ake adana kumfa nickel?
1. Kafa kumfa nickel don rage yawan amfani da albarkatun kasa, tare da babban girma da nauyi mai nauyi, buƙatar rigakafin wuta, hana ruwa, samun iska da sauran buƙatun; Kafa dakin ajiya ajiya: Tana da sifofin da yawa iri, iri iri, jakunkuna filastik danshi-hujja, da sauransu. kafa ɗakin ajiyar sinadarai, kayan ƙarfe: babban ƙwaƙwalwar ajiyar nickel na ƙarfe
2. An saita adadin samfurori na layin samar da nickel mai kumfa bayan kowane yanki na ajiya. Don sauƙaƙe sarrafawa, ajiya da juyawa, an saita ɗakunan ajiya na samarwa don samfurori na musamman.
3. Abubuwan kumfa na nickel sun ƙunshi sassa biyu: kashi na farko shine samfurin da aka gama ba tare da shearing ba, wanda aka adana shi daban don hana haɗuwa da extrusion. Wadannan sassa biyu ana yanke su bisa ga bukatun mai amfani da samfurin, kuma an yi musu alama a fili a kan kunshin. Ma'ajiya, marufi, tabbatar da danshi da juriya sun cika ka'idojin otal.
