Daga ina ake ciro kumfa nickel?

Kumfa nickelabu ne da ake amfani dashikera wayoyin batir,Hanyar samar da kumfa na nickel gabaɗaya ita ce: soso na farko na polyurethane, sannan electrodeposition, kuma a ƙarshe sintering.

A cikin wannan tsari, electroplating gabaɗaya yana amfani da plating sinadarai, electroplating conductive m da vacuum plating hanyoyi uku; electrodeposition za a iya amfani da sulfate ko sulfamate nickel plating; Manufar tsarin sintiri shine don ƙone soso na polyurethane a cikin iska a cikin yanayi na raguwa na hydrogen don rage raguwar hanyoyi guda biyu, wanda iska ta ƙone daga soso na polyurethane ta amfani da oxidation na 300 ~ 700 ℃ decarburization; a 800 ~ 1000 ℃ hydrogen rage yanayi na 30 ~ 60 minutes for sintering rage, da rage yanayi kasancewa ammonia bazuwar gas tare da bazuwar iskar gas amfani na 0.8 ~ 1.2 L / g (0.8 ~ 1.2 lita na ammonia bazuwar gas da gram na nickel) .

Wannan hanyar tana da alaƙa da hanyar shirya kumfa nickel daga soso na polyurethane ta hanyar gudanarwa,electrodeposition da sintering, Hali a cikin cewa sintering mataki ne kai tsaye pyrolytic electrodeposition na kumfa polyurethane a cikin wani rage yanayi, inda da rage yanayi ne ammonia bazuwar gas, da rage zafin jiki ne 400-1000 ° C, da rage lokaci ne 30-60 minti, da kuma Amfani da iskar gas shine 0.4-0.8 L/g. Ammoniya bazuwar gas (cinyewar 0.4-0.8 L / g na nickel da gram). 0.4-0.8 L na ammoniya bazuwar iskar gas) wani cakuda nitrogen da hydrogen tare da adadin girma na 1: 3.

Hanyar amsawa tana cikin yanayin raguwar hydrogen, tare da electrodeposition nanickel kumfadauke da polyurethane soso kai tsaye pyrolysis sintering, carbon da hydrogen, sakamakon gaseous hydrocarbons, kamar CH4, C2H6, wannan gasification tsari na iya sa graphite a cikin porous jiki na C cleaner cire.
