Kodi thovu la nickel limachokera kuti?

Chithovu cha Nickelndi zinthu zomwe zimagwiritsidwa ntchitokupanga ma electrode a batri,wamba faifi tambala thovu kupanga njira ndi: choyamba conductive polyurethane siponji, ndiye electrodeposition, ndipo potsiriza sintering.

Pochita izi, electroplating amagwiritsa ntchito plating mankhwala, electroplating conductive zomatira ndi vacuum plating njira zitatu; electrodeposition angagwiritsidwe ntchito sulphate kapena sulfamate nickel plating; Cholinga cha sintering ndi kuwotcha siponji ya polyurethane mumlengalenga mu mpweya wa hydrogen kuchepetsa sintering njira ziwirizi, momwe mpweya unawotcha siponji ya polyurethane pogwiritsa ntchito okosijeni wa 300 ~ 700 ℃ decarburization; mu 800 ~ 1000 ℃ hydrogen kuchepetsa mpweya kwa 30 ~ 60 mphindi kuchepetsa sintering, kuchepetsa mpweya kukhala ammonia kuwola mpweya ndi kuwola gasi kumwa 0.8 ~ 1.2 L/g (0.8 ~ 1.2 malita a ammonia kuwola mpweya pa gramu faifi tambala) .

Njirayi ikukhudzana ndi njira yopangira thovu la faifi tambala kuchokera ku siponji ya polyurethane ndi conductivization,electrodeposition ndi sintering, yodziwika kuti sitepe sintering ndi mwachindunji pyrolytic electrodeposition wa thovu polyurethane mu mpweya kuchepetsa, mmene kuchepetsa mpweya ndi ammonia kuwola mpweya, kuchepetsa kutentha ndi 400-1000 ° C, kuchepetsa nthawi ndi 30-60 mphindi, ndi kugwiritsa ntchito gasi wowola ndi 0.4-0.8 L/g. Kuwonongeka kwa mpweya wa ammonia (kugwiritsa ntchito 0.4-0.8 L / g ya nickel pa gramu). 0.4-0.8 L wa mpweya wowola wa ammonia) ndi chisakanizo cha nayitrogeni ndi haidrojeni wokhala ndi chiŵerengero cha 1:3.

Zomwe zimapangidwira zili mumlengalenga wa hydrogen kuchepetsa, ndi electrodeposition yanickel thovumunali polyurethane siponji mwachindunji pyrolysis sintering, mpweya ndi haidrojeni, chifukwa mu mpweya hydrocarbons, monga CH4, C2H6, ndondomeko gasification akhoza kupanga graphite mu porous thupi la C zotsukira kuchotsa.
