Cov nickel ua npuas ncauj muab rho tawm los ntawm qhov twg?

Nickel ua npuas ncaujyog ib yam khoom sivtsim cov roj teeb electrodes,Cov txheej txheem nickel ua npuas ncauj yog: thawj zaug conductive polyurethane daim txhuam cev, ces electrodeposition, thiab thaum kawg sintering.

Hauv cov txheej txheem no, electroplating feem ntau siv tshuaj plating, electroplating conductive nplaum thiab nqus plating peb txoj kev; electrodeposition yuav siv tau sulfate los yog sulfamate nickel plating; Lub hom phiaj ntawm cov txheej txheem sintering yog kom hlawv tawm ntawm polyurethane sponge nyob rau hauv cov huab cua nyob rau hauv ib tug hydrogen txo cua rau sintering txo ntawm ob txoj kev, nyob rau hauv uas cov huab cua hlawv tawm ntawm polyurethane daim txhuam cev siv oxidation ntawm 300 ~ 700 ℃ decarburization; nyob rau hauv 800 ~ 1000 ℃ hydrogen txo qhov cua rau 30 ~ 60 feeb rau sintering txo, qhov txo qhov cua yog ammonia decomposition gas nrog ib tug decomposition roj noj ntawm 0.8 ~ 1.2 L / g (0.8 ~ 1.2 litres ntawm ammonia decomposition gas ib gram ntawm nickel) .

Txoj kev no muaj feem xyuam rau ib txoj hauv kev npaj nickel ua npuas ncauj los ntawm polyurethane daim txhuam cev los ntawm kev siv hluav taws xob,electrodeposition thiab sintering, tus cwj pwm nyob rau hauv hais tias cov kauj ruam sintering yog ncaj qha pyrolytic electrodeposition ntawm cov npuas dej polyurethane nyob rau hauv ib tug txo qhov cua, nyob rau hauv qhov txo qhov cua yog ammonia decomposition gas, txo qhov kub ntawm 400-1000 ° C, txo lub sij hawm yog 30-60 feeb, Kev noj cov roj decomposition yog 0.4-0.8 L / g. ammonia decomposition gas (siv ntawm 0.4-0.8 L / g ntawm nickel ib gram). 0.4-0.8 L ntawm ammonia decomposition gas) yog sib xyaw ntawm nitrogen thiab hydrogen nrog qhov ntim piv ntawm 1: 3.

Cov tshuaj tiv thaiv mechanism yog nyob rau hauv cov huab cua txo hydrogen, nrog electrodeposition ntawmnickel ua npuas ncaujmuaj polyurethane daim txhuam cev ncaj qha pyrolysis sintering, carbon thiab hydrogen, ua rau gaseous hydrocarbons, xws li CH4, C2H6, cov txheej txheem gasification no tuaj yeem ua rau cov graphite hauv lub cev ntxeem tau ntawm C huv huv tshem tawm.
