Kushandisa Zvigadzirwa
Hafnium kushandiswa kunogumira nekuda kwekuderera kuwanda. Iyo yekutanga kushandiswa kwehafnium iri muindasitiri yenyukireya, kwainoshandiswa mumafuta emafuta kudzora fission yakapihwa yakakwirira neutron absorption cross chikamu. Zvakafanana ne zirconium, hafnium yakasanganiswa ne niobium uye carbide kuti igadzire tembiricha inodzivirira zvinhu zvevira uye jet components pamwe chete neplasma cutters. Pamusoro pezvo, hafnium oxide iri kuwedzera kushandiswa kuwedzera kana kutsiva silicone oxidebased microprocessor chips mune mamwe maapplication pamwe nemacathodes uye capacitors (Field et al., 2011). Hafnium ine hukama hukuru hwekutora manyutroni anononoka. Hunhu uhwu, pamwe chete nekusimba kwayo uye kuramba kukorokoza, hunoita kuti ive nani pane cadmium, iyo inoshandiswawo kugadzira tsvimbo dzekudzora nyukireya. Kushandiswa uku kunonyanya kukosha kune rudzi rwenyukireya reactor anoshandiswa mungarava dzepasi pemvura. Nekufambisa matomu ekudzora mukati nekubuda muchinhu chenyukireya, fission chain reaction inogona kudzorwa sezvo manyuturoni anotorwa musimbi yematanda. Kudzora kune hafnium control rods imari yavo: inodhura ingangoita miriyoni imwe yemadhora kune gumi nemaviri rodhi kuti ishandiswe mune imwechete nuclear reactor.Muvacuum chubhu uye mamwe maapplication anofanirwa kunge akabviswa magasi, hafnium inoshandiswa se "getter" kutora chero trace. okisijeni kana nitrogen muchubhu, nokudaro uchiwedzera hupenyu hwevacuum chubhu. Hunhu hweHafnium hunoitawo kuti ive yakanaka kune mafilaments ari mumwenje magirobhu uye, kana yakasanganiswa nesimbi isingawanzo simbi, se "sparking" misch simbi. Hafnium inoshandiswawo kune isingaite seyakagadziriswa alloying kune akati wandei mamwe masimbi, anosanganisira iron, titanium, uye niobium. Inowanikwa mukuchera nekucheneswa kwesimbi; inoshandiswa mukudzora tsvimbo mumagetsi enyukireya uye mukugadzira mafilamende egirobhu; inowanikwa mune zvese zirconium ine zvicherwa.
Package Uye Kuchengeta
Packing:
Yakarongedzwa mumvura-isina mvura yepurasitiki yakarukwa bag, 25kg pabhegi kana sezvinodiwa zvako.
Remark: Kemikari kuumbwa uye saizi inogona kuvandudzwa nezvinodiwa nevatengi
Mamiriro ekuchengetedza akachengeteka, kusanganisira chero kusawiriranas
Isingapindi moto. Yakaparadzaniswa kubva kune yakasimba oxidants, yakasimba asidhi nemahalojeni. Ramba uri pasi pegesi inert. Chengetedza mugaba rekutanga chete.Kuchengeta: Chengeta hafnium munzvimbo isingatsvi. Ichengetedze yakaparadzana kubva kune yakasimba oxidizing agents, mabhesi akasimba, halogens, phosphorus, uye sarufa. Ramba wakachengetwa pasi pemvura.
Safety Protection
Chengetedzo yekubata zvakachengeteka
HAPANA mwoto wakavhurika, HAPANA pfarivari uye HAPANA kuputa. Usafumure kune friction kana kuvhunduka. Yakavharwa sisitimu, huruva inoputika-inodzivirira midziyo yemagetsi uye mwenje. Dzivirira kuiswa kweguruva. Kubata munzvimbo ine mhepo yakanaka. Pfeka zvipfeko zvinodzivirira zvakakodzera. Dzivisa kusangana neganda nemaziso. Dzivisa kuumbwa kweguruva uye aerosols. Shandisa midziyo isiri-sparking. Dzivirira moto unokonzerwa ne electrostatic discharge steam.
