Horudhac ku saabsan daaweynta hore ee xumbo nikkel

Xumbo Nickelwaa wax loo isticmaalo samaynta electrodes baytari, iyo habka wax soo saarka ee walxaha caadiga ah ee nikkel xumbo waa sida soo socota: polyurethane sponge marka hore waa conductivized, ka dibna electrodeposited, iyo ugu dambeyntii sintered.

Tallaabooyinka kor ku xusan, daawaynta laqabsashada guud ahaan waxaa ku jiradahaadhida kiimikaad, dahaarka xabagta, iyo dahaadhidda faakuumkasaddex siyaabood; Electrodeposition wuxuu noqon karaa sulfate ama sulfamate nikkel; Habka qallafsanaanta jira ayaa marka hore lagu dhammeeyaa iyada oo hawada laga gubo isbuunyada polyurethane, ka dibna la yareeyo oo la jeexjeexo isbuunyada hoosteeda jawiga yareeya hydrogen laba tillaabo, halkaas oo hawada gubanaya isbuunyada poliurethane ay oksaydhized iyo kaarbonized heerkul ah 300 ilaa 700 °C. Habka qallafsanaanta waxaa lagu dhammeeyaa iyada oo hawada laga gubo isbuunyada poliurethane, ka dibna la yareeyo oo la gooyo isbuunyada poliurethane ee jawiga yareeya hydrogen; Daaweynta dhimista waxaa lagu sameeyaa jawi hoos u dhigista hydrogen oo heerkul ah 800 ilaa 1000 ° C 30-60 daqiiqo, iyo jawiga dhimista waa gaaska kala-goynta ammonia, iyo qadarka gaaska burburka ee la isticmaalo waa 0.8-1.2 L / g (gram kasta Nikkel wuxuu u baahan yahay 0.8-1.2 litir oo gaasta ammonia ah si loo isticmaalo

Habka samaynta oo la hagaajiyayxumbo nikkel, Tallaabada taas oo ka kooban conductivization, electrodeposition iyo sintering ee isbuunyo polyurethane ah, lagu gartaa in tallaabada sintering sheegay in ay tahay in pyrolyze iyo sinter xumbo polyurethane si toos ah jawi yaraynta ka dib markii electrodeposition, halkaas oo jawi yaraynta waa ammonia gaaska burburay, heerkulka hoos u dhaca. waa 400-1000 ° C., wakhtiga dhimista waa 30-60 daqiiqo, iyo qadarka isticmaalka gaaska burburay waa 0.4-0.8 L/g. (Graam kasta oo nikkel ah waxa uu u baahan yahay in uu isticmaalo 0.4-0.8 litir oo gaas kala-soocista ammonia ah.) Gaaska kala-goynta ammonia waa isku dhafka nitrogen iyo hydrogen, saamiga mugga ee nitrogen iyo hydrogen waa 1: 3.

Habka falcelinta waa in ka dib markii electrodeposition ofxumbo nikkeloo ka kooban polyurethane isbuunyo si toos ah in hydrogen dhimista jawi pyrolysis sintering, halkaas oo kaarboon iyo fal hydrogen, dhalinaya CH4, C2H6 iyo hydrocarbons kale gaseous, habka gaaska kor ku xusan waa ku filan in meesha laga saaro graphite C ee nadiifiyaha jirka dalool.

Waxay si wax ku ool ah u xallisaa cilladaha jira ee tignoolajiyada jira ee xumbo nikkel ee geeddi-socodka sintering, sida fududahay in la dillaaco, arching qallafsan, dhalidda hooseeyo, isticmaalka tamarta sare, guryaha farsamada nikkel xumbo ma aha mid deggan.
