Application

Hafnium poda inoshandiswa mumhando dzakasiyana dzekushandisa nekuda kweiyo yakasarudzika zvivakwa. Zvimwe zvezvinonyanya kushandiswa zvinosanganisira:

1. Kushandisa Nuclear: Hafnium ine high neutron absorption cross section uye naizvozvo inoshandiswa sechinhu chekudzora tsvimbo yemagetsi enyukireya. Inobatsira kudzora iyo fission process nekutora yakawandisa neutron.

2. Alloy: Hafnium inowanzoshandiswa mumagetsi kuti iwedzere simba ravo uye kusagadzikana kwekuora, kunyanya mukushandiswa kwepamusoro-kupisa. Inowanzowedzerwa kune superalloys inoshandiswa mune aerospace uye turbine injini.

3. Electronics: Hafnium oxide (HfO2) inoshandiswa mumhizha ye semiconductor se-high-k dielectric material in transistors, inobatsira kuvandudza microelectronic performance uye kuderedza kushandiswa kwesimba.

4. Kemikari Catalyst: Hafnium compounds inogona kushandiswa sezvinokonzera maitiro akasiyana-siyana emakemikari, kunyanya mukugadzirwa kwemamwe mapolymers nezvimwe zvinhu.

5. Tsvakurudzo uye Kubudirira: Hafnium powder inoshandiswawo munzvimbo dzekutsvakurudza kune zvakasiyana-siyana zvekuedza, kusanganisira tsvakurudzo mune zvesayenzi uye nanotechnology.

6. Kuvhara: Hafnium inogona kushandiswa mumafirimu akaonda uye machira kuti awedzere zvinhu zvezvinhu, zvakadai sekuvandudza kupfeka kusagadzikana uye kugadzikana kwekupisa.

Pakazere, hafnium poda inokosheswa kune yayo yakakwira kunyungudika, corrosion resistance, uye kugona kutora manyutroni, zvichiita kuti ive chinhu chinochinjika kune akasiyana siyana ekushandisa.

Storage

Chengetedza muimba yekuchengetera inotonhorera uye ine mhepo. Gara kure nemanyuko emoto nekupisa. Inofanira kuchengetwa zvakasiyana kubva kune oxidants, acids, halogens, nezvimwewo, uye kudzivisa kusanganisa kuchengetedza. Gamuchira mwenje unodzivirira kuputika uye nzvimbo dzekufemesa. Rambidza kushandiswa kwemichina uye maturusi anowanzo gadzira sparks. Nzvimbo yekuchengetera inofanirwa kunge yakashongedzerwa nemidziyo yakakodzera kuti ive nezvinhu zvakadeuka.

Hafnium ine ngozi here?

Hafnium pachayo haina kurongeka sechinhu chine njodzi sedzimwe simbi, asi pachine zvinhu zvakakosha zvekucherechedza nezvekuchengetedza kwayo:

1. Muchetura: Hafnium inowanzoonekwa seine muchetura wakaderera. Zvisinei, kuratidzirwa kune hafnium powder (kunyanya mune yakanaka particle form) inogona kuisa njodzi yehutano, kunyanya kana yakafemerwa.

2. Inhalation Risk: Kufema kweguruva rehafnium kunogona kutsamwisa hurongwa hwekufema. Kuratidzwa kwenguva refu kana kwepamusoro-soro kunogona kukonzera hutano hwakanyanya.

3. GANDA NEZISO: Hafnium huruva inogona kukonzera kutsamwa kana ikasangana neganda kana maziso. Midziyo yekudzivirira inofanirwa kushandiswa kuderedza njodzi iyi.

4. Dambudziko rekuputika kweguruva: Kufanana nehupfu hwesimbi zhinji, hafnium inoisa njodzi yekuputika kweguruva kana ikaita mhepo uye kudzika kunosvika kumwero wakati. Kubata kwakakodzera uye nzira dzekuchengetedza dzakakosha kudzikisa njodzi iyi.

5. Kemikari Reactivity: Hafnium inogona kugadzikana neine oxidants yakasimba uye inofanira kutarisirwa nekuchenjerera pamberi pezvinhu zvakadaro.

 

Matanho ekukurumidzira

Kubata ganda: Sukurudza nemvura inoyerera.
Kubata maziso: Sukurudza nemvura inoyerera.
Inhalation: Bvisa kubva panzvimbo.
Kudya: Avo vanodya netsaona vanofanira kunwa mvura yakawanda inodziya, kurutsa, uye kutsvaga kurapwa.
