Nickel foam ndi zinthu zomwe zimagwiritsidwa ntchito popanga ma electrode a batri. Nthawi zambiri, kupanga njira ya faifi tambala zakuthupi ndi motere: choyamba conductive polyurethane siponji, ndiye electrodeposition, ndipo potsiriza sintering.
Pochita izi, electroplating imagwiritsa ntchito njira zitatu: electroless plating, electroplating conductive zomatira ndi vacuum plating; electrodeposition angagwiritse ntchito sulphate kapena sulfamate nickel plating; Cholinga cha sintering ndi kutentha siponji ya polyurethane mumlengalenga ndikuyichepetsa mu haidrojeni. Pali njira ziwiri zochepetsera sintering mumlengalenga, momwe siponji ya polyurethane imawotchedwa mumlengalenga ndi chithandizo cha oxidative decarburization pa 300 ~ 700 ° C; sintering ndi kuchepetsa zimachitika mu mpweya kuchepetsa pa 800 ~ 1000 °C pansi wa hydrogen kuchepetsa mpweya kwa mphindi 30 ~ 60, kuchepetsa mpweya ndi ammonia kuwola mpweya, ndi kumwa mpweya wovunda ndi 0.8~1.2 L/g (0.8) ~ 1.2 malita a mpweya wowola wa ammonia amadyedwa pa gramu imodzi ya faifi tambala).
Njirayi ikukhudzana ndi njira yokonzekera nickel thovu poyendetsa, electrodeposition ndi sintering wa polyurethane siponji. Kuchepetsa kutentha ndi 400 ~ 1000 ℃, kuchepetsa nthawi ndi 30 ~ 60 mphindi, ndi kumwa mpweya kuwola ndi 0.4 ~ 0.8 L/g. Mpweya wowola wa ammonia (0.4-0.8 malita a mpweya wowola wa ammonia umadyedwa pa gramu imodzi ya nickel) ndi chisakanizo cha nayitrogeni ndi haidrojeni, ndipo chiŵerengero chake ndi 1:3.
Zomwe zimapangidwira ndikuti mumlengalenga wochepetsera wa haidrojeni, thovu la nickel lomwe lili ndi siponji ya polyurethane imapangidwa mwachindunji ndi sintered ndi electrodeposition, ndipo mpweya ndi haidrojeni zimachita kupanga ma hydrocarbon a mpweya monga CH4 ndi C2H6. Izi gasification ndondomeko akhoza kupanga graphite mu porous thupi. C imakhala yoyeretsa.
Kodi thovu la nickel limasungidwa bwanji?
1. Khazikitsani thovu la faifi tambala kuti muchepetse kugwiritsa ntchito zopangira, zokhala ndi voliyumu yayikulu komanso kulemera kopepuka, zomwe zimafunikira kupewa moto, kutsekereza madzi, mpweya wabwino ndi zina zofunika; khazikitsani chipinda chosungiramo mankhwala: ili ndi mawonekedwe amitundu yambiri, kugwiritsa ntchito kwakukulu, matumba apulasitiki otsimikizira chinyezi, mpweya wabwino, ndi zina zambiri; kukhazikitsa chipinda chosungiramo mankhwala, zinthu zachitsulo: kukumbukira kwakukulu kwa nickel yachitsulo
2. Chiwerengero cha zinthu za mzere wopanga nickel wa thovu zimayikidwa pambuyo pa malo aliwonse osungira. Pofuna kuwongolera kukonza, kusungirako ndi kuzungulira, zopangira zosungiramo zinthu zapadera zimayikidwa.
3. Zopangira thovu za nickel zimapangidwa ndi magawo awiri: gawo loyamba ndi chinthu chomalizidwa popanda kumeta ubweya, chomwe chimasungidwa padera kuti chiteteze kugunda ndi kutulutsa. Magawo awiriwa amametedwa malinga ndi zosowa za wogwiritsa ntchito, ndipo amalembedwa bwino pa phukusi. Kusungirako, kulongedza, kusatetezedwa kwa chinyezi komanso kupanikizika kumakwaniritsa miyezo ya hotelo.
