Intangiriro yo kwitiranya nikel ifuro

Nickel ifuroni ibikoresho bikoreshwa mugukora amashanyarazi ya batiri, kandi uburyo bwo gukora ibintu bisanzwe bya nikel ifuro nibi bikurikira: sponge ya polyurethane yabanje gukoreshwa, hanyuma electrodepositike, hanyuma ikacumura.

Muri izi ntambwe zavuzwe haruguru, ubuvuzi buyobora burimogusiga imiti, gutwikira ibintu bifata neza, hamwe na vacuummu buryo butatu; electrodeposition irashobora kuba sulfate cyangwa sulfamate nikel; uburyo bwo gucumura buriho bwabanje kurangizwa numwuka utwika sponge ya polyurethane, hanyuma ukagabanya no gucumura sponge munsi ya hydrogène igabanya ikirere mubyiciro bibiri, aho umwuka utwika sponge ya polyurethane uba oxyde kandi ugashyirwa mubushyuhe bwa dogere 300 kugeza 700 ° C. Igikorwa cyo gucumura kirangizwa numwuka utwika sponge ya polyurethane, hanyuma ukagabanya no gucumura sponge ya polyurethane muri hydrogène igabanya ikirere; Kugabanya kugabanya bikorwa mu kirere cyo kugabanya hydrogène ku bushyuhe bwa 800 kugeza 1000 ° C mu minota 30-60, naho ikirere cyo kugabanya ni gaze yangirika ya amoniya, kandi gaze ya gaze ikoreshwa ni 0.8-1.2 L / g (buri garama ya nikel isaba litiro 0.8-1.2 ya gaze ya amoniya yangirika gukoreshwa)

Uburyo bunoze bwo gukoranikel, intambwe igizwe na conivivisation, electrodeposition no gucumura sponge ya polyurethane, irangwa muri iyo ntambwe yo gucumura ni pyrolyze no gucumura ifuro rya polyurethane mu buryo butaziguye mu kirere kigabanya nyuma ya electrodeposition, aho ikirere kigabanya ari gaze yangirika ya amoniya, kugabanya ubushyuhe ni 400-1000 ° C., kugabanya igihe ni iminota 30-60, naho ingano yo gukoresha gaze yangirika ni 0.4-0.8 L / g. .

Uburyo bwa reaction ni uko nyuma ya electrodeposition yanikelirimo sponge ya polyurethane mu buryo butaziguye mu kirere cya hydrogène igabanya ikirere cya pyrolysis, aho ibikorwa bya karubone na hydrogène, bibyara CH4, C2H6 hamwe na hydrocarbone ya gaze ya gaze, inzira ya gazi yavuzwe haruguru irahagije kugirango ikureho grafite C mu isuku yumubiri.

Ikemura neza ibitagenda neza muburyo bwa tekinoroji isanzwe ya nikel ifuro mugikorwa cyo gucumura, nko koroshya gucika, kubika deformasiyo, umusaruro muke, gukoresha ingufu nyinshi, ibikoresho bya nikel ifuro ntabwo bihamye.
