Nickel ua npuas ncauj, feem ntau siv los ua cov roj teeb electrodes, muaj ntau lwm yam kev siv tau tshawb nrhiav. Piv nrog npib tsib xee phaj thiab npib tsib xee mesh, qhov zoo ntawm foamed npib tsib xee yog pom tseeb. Txoj kev tsim khoom dav dav ntawm cov khoom siv npib tsib xee foamed yog raws li nram no: ua ntej, polyurethane daim txhuam cev yog electrified, ces electrodeposited, thiab ces sintered. Txoj kev no siv electroless plating, electroplating txoj kev thiab nqus plating txoj kev; txoj kev electroplating tuaj yeem siv sulfate lossis sulfamate nickel plating; Cov txheej txheem sintering yog txhawm rau hlawv cov polyurethane daim txhuam cev hauv huab cua, thiab ua kom cov sintering-txo cov tshuaj tiv thaiv nyob rau hauv hydrogen txo qhov chaw. Ib txoj kev, nyob rau hauv uas polyurethane daim txhuam cev yog hlawv nyob rau hauv cov huab cua los ntawm oxidation decarburization kev kho mob; Nyob rau hauv ib tug hydrogen txo cua, ib tug 30-60 feeb txo cua yog siv rau sintering txo, qhov txo cua sov yog ammonia decomposition gas, thiab cov roj yuav tsum tau noj yog 0.8-1.2 litres.
Cov txheej txheem muaj feem xyuam rau txoj kev npaj foamed npib tsib xee los ntawm kev siv polyurethane daim txhuam cev los ua hluav taws xob, electrodeposition, sintering, thiab lwm yam. ammonia decomposition gas. Cov tshuaj tiv thaiv mechanism yog: nyob rau hauv ib tug hydrogen txo qhov chaw, cov nickel ua npuas ncauj ntawm lub electrodeposited polyurethane daim txhuam cev yog ncaj qha pyrolyzed thiab sintered, thiab cov pa roj carbon thiab hydrogen react los tsim gaseous hydrocarbons xws li CH4 thiab C2H6. Cov txheej txheem gasification no tuaj yeem ua kom huv Graphite C raug tshem tawm ntawm lub cev ntxeem tau.
