Imikoreshereze y'ibicuruzwa
Gukoresha Hafnium ni bike kubera ubwinshi. Ikoreshwa ryambere rya hafnium riri mu nganda za kirimbuzi, aho rikoreshwa mu nkoni za lisansi kugirango igabanye imyuka bitewe n’igice kinini cyayo cya neutron. Kimwe na zirconium, hafnium ivanze na niobium na karbide kugirango itange ibikoresho byo kugabanya ubushyuhe bwo hejuru ku ziko hamwe nibice bya jet kimwe no gukata plasma. Byongeye kandi, okiside ya hafnium iragenda ikoreshwa mu kongera cyangwa gusimbuza silicone oxyde ya microprocessor chip muri porogaramu zimwe na zimwe ndetse no muri cathodes na capacator (Field et al., 2011). Hafnium ifite isano ikomeye yo gukuramo neutron buhoro. Iyi miterere, hamwe nimbaraga zayo no kurwanya ruswa, bituma iruta kadmium, nayo ikoreshwa mugukora inkoni zo kugenzura ibyuma bya kirimbuzi. Iyi mikoreshereze ifite akamaro kanini kubwoko bwa reaction ya kirimbuzi ikoreshwa mubwato. Mu kwimura inkoni zo kugenzura no gusohora ingufu za kirimbuzi, reaction ya fonction reaction irashobora kugenzurwa kuko neutron iba yinjiye mubyuma byinkoni. Ingaruka zo kugenzura inkoni ya hafnium nizo zikoresha: bisaba amadorari agera kuri miriyoni y'amadorari ku nkoni nyinshi zo gukoresha mu cyuma kimwe cya kirimbuzi. Mu tubari twa vacuum no mu zindi porogaramu zigomba gukurwaho gaze, hafnium ikoreshwa nka “getter” kugira ngo ikureho ibimenyetso byose. ogisijeni cyangwa azote mu muyoboro, bityo bikongerera ubuzima umuyoboro wa vacuum. Imico ya Hafnium nayo ituma biba byiza kuri filaments mumatara kandi, iyo bivanze nubutaka budasanzwe-bwisi, nkicyuma kibi "giteye". Hafnium nayo ikoreshwa muburyo butagaragara nkumuti uhuza ibindi byuma byinshi, birimo ibyuma, titanium, na niobium. Kubona mu bucukuzi no kweza ibyuma; ikoreshwa mu kugenzura inkoni mu bikoresho bya kirimbuzi no mu gukora amatara yaka; iboneka muri zirconium zose zirimo amabuye y'agaciro.
Ububiko nububiko
Gupakira:
Gupakirwa mumifuka idakoreshwa mumazi, 25kg kumufuka cyangwa nkuko ubisabwa.
Icyitonderwa: Ibigize imiti nubunini birashobora gutezimbere ibyifuzo byabakiriya
Ibisabwa kugirango ubike neza, harimo na compatibilitie iyo ari yo yoses
Amashanyarazi. Bitandukanijwe na okiside ikomeye, acide ikomeye na halogene. Komeza munsi ya gaze ya inert. Ubike gusa muri kontineri yumwimerere.Ububiko: Bika hafnium ahantu hatarimo umuriro. Komeza utandukanye nibintu bikomeye bya okiside, base ikomeye, halogene, fosifore, na sulferi. Komeza kubikwa munsi y'amazi.
Kurinda umutekano
Icyitonderwa cyo gufata neza umutekano
NTA muriro ufunguye, OYA ibishashi kandi NTA itabi. Ntugaragaze guterana amagambo cyangwa guhungabana. Sisitemu ifunze, ibikoresho byamashanyarazi biturika kandi bitara. Irinde guta umukungugu. Gukorera ahantu hafite umwuka mwiza. Wambare imyenda ikingira. Irinde guhura n'uruhu n'amaso. Irinde gushiraho umukungugu na aerosole. Koresha ibikoresho bidacana. Irinde umuriro uterwa na electrostatike isohoka.
