Pretreatment ntawm nickel ua npuas ncauj
Sep 02, 2022
Nickel ua npuas ncauj yog cov khoom siv suab nrov zoo nrog lub suab nrov nqus coefficient ntawm qhov siab; nws lub suab nqus kev ua tau zoo ntawm qhov tsawg zaus tuaj yeem txhim kho los ntawm kev tsim qauv ntawm lub suab nqus. Nickel ua npuas ncauj kuj yog ib qho ntawm cov khoom siv electrode zoo tshaj plaws rau kev tsim cov roj teeb cadmium-nickel thiab hydrogen-nickel roj teeb. Nickel ua npuas ncauj nws tus kheej muaj ntau yam zoo heev. Tsis tsuas yog nws qhov tshwj xeeb lub ntiajteb txawj nqus tsawg heev, tab sis kuj nws qhov chaw tshwj xeeb yog me me; nws qhov loj yog ultra-teeb, uas muaj ntau yam kev siv thiab kev cia siab rau kev thov. Ua ntej siv, nws yuav tsum tau kho ua ntej. Tsuas yog thaum cov hlau pretreated tuaj yeem txhim kho nws lub zog efficiency.
Nickel ua npuas ncauj pretreatment: Nickel ua npuas ncauj yog txiav mus rau qhov loj me rau cov qauv thiab impregnated nyob rau hauv ib tug 3.0 mol / L HCl tov rau 20 feeb kom tshem tawm cov oxide txheej ntawm nws nto. Tom qab ntawd, cov npib tsib xee ua npuas ncauj raug tshem tawm, yaug ntau zaus nrog dej ethanol thiab dej ultrapure, qhuav lawm, thiab impregnated hauv anhydrous ethanol thiab tso tseg. Thaum cov electrolyte yog acidic, nickel ua npuas ncauj yuav tsum tsis txhob siv los ua substrate.
