【Isisindo samangqamuzana】137.33
[Izakhiwo Zemvelo Nezamakhemikhali] Insimbi ethambile esiliva ephuzi. Ukuminyana okuhlobene 3.62, iphoyinti elincibilikayo 725 ℃, indawo yokubilisa 1640 ℃. I-cubic egxile emzimbeni: α=0.5025nm. Ukushisa okuncibilikayo 7.66kJ/mol, ukushisa kwe-vaporization 149.20kJ/mol, umfutho we-vapor 0.00133kpa (629 ℃), 1.33kPa (1050 ℃), 101.3kPa (1640 ℃), resistivity 0Ω2 cm. I-Ba2+ ine-radius engu-0.143nm kanye ne-thermal conductivity engu-18.4 (25 ℃) W/(m · K). Umugqa wokunweba i-coefficient 1.85 × 10-5 m/(M ·℃). Ezingeni lokushisa legumbi, isabela kalula emanzini ukuze ikhiphe igesi ye-hydrogen, encibilika kancane otshwaleni futhi engancibiliki ku-benzene.
[Amazinga Ekhwalithi]Amazinga Okubhekisela
【Uhlelo】Isetshenziswa kabanzi kuma-alloys e-degassing, kufaka phakathi umthofu, i-calcium, i-magnesium, i-sodium, i-lithium, i-aluminium, ne-nickel alloys. Isetshenziswa njengesicindezeli segesi ukususa amagesi okulandela umkhondo asele kumashubhu e-vacuum angenawaya, futhi isetshenziswa nasekukhiqizeni usawoti we-barium.
Indlela yokunciphisa ukushisa kwe-Aluminium: I-Barium nitrate ibola ngokushisa ukuze ikhiqize i-barium oxide. I-aluminium emihle isetshenziswa njenge-ejenti yokunciphisa, futhi isilinganiso sezithako yi-3BaO: 2A1. I-Barium oxide ne-aluminium kuqala kwenziwa ama-pellets, abese efakwa endaweni ethule futhi eshiselwe ku-1150 ℃ ukuze kuncishiswe ukuhlanzwa kwe-distillation. Ukuhlanzeka kwe-barium ephumela ku-99%.
【Ukuphepha】Uthuli luthambekele ekushiseni okuzenzakalelayo ekamelweni lokushisa futhi lungabangela ukuvutha nokuqhuma lapho sivezwe ukushisa, amalangabi, noma ukusabela kwamakhemikhali. Ijwayele ukubola amanzi futhi isabela ngobudlova nama-asidi, ikhiphe igesi ye-hydrogen engabaswa ukushisa kokusabela. Ukuhlangana ne-fluorine, i-chlorine, nezinye izinto kungabangela ukusabela kwamakhemikhali okunodlame. I-barium metal iphendulana namanzi yenze i-barium hydroxide, enomthelela olonakalisayo. Ngesikhathi esifanayo, usawoti we-barium oncibilikayo emanzini unobuthi obukhulu. Le nto ingase ibe yingozi emvelweni, kunconywa ukuthi ungayivumeli ingene endaweni ezungezile.
Ikhodi yengozi: Into evuthayo lapho ithinta umswakama. GB 4.3 Ikilasi 43009. UN No. 1400. I-IMDG KHODI 4332 ikhasi, Ikilasi 4.3.
Uma uyithatha ngephutha, phuza amanzi amaningi afudumele, yenza ukuhlanza, ugeze isisu ngesisombululo se-sodium sulfate engu-2% kuya ku-5%, ubangele isifo sohudo, futhi ufune usizo lwezokwelapha. Ukuhogela uthuli kungabangela ubuthi. Iziguli kufanele zikhishwe endaweni engcolile, ziphumule, futhi zigcinwe zifudumele; Uma ukuphefumula kuyeka, ngokushesha yenza ukuphefumula okwenziwa futhi ufune usizo lwezokwelapha. Ukuchaphaza ngephutha emehlweni, hlambulula ngamanzi amaningi, funa ukwelashwa ezimeni ezinzima. Ukuthinta isikhumba: Hlanza ngamanzi kuqala, bese ugeza kahle ngensipho. Uma kukhona ukusha, funa ukwelashwa. Hlanza umlomo wakho ngokushesha uma ugwinywe ngephutha futhi ufune ukwelashwa ngokushesha.
Lapho uphatha i-barium, kuyadingeka ukuqinisa izinyathelo zokuvikela ukuphepha kwabaqhubi. Yonke imfucuza kufanele iphathwe nge-ferrous sulfate noma i-sodium sulfate ukuguqula usawoti we-barium onobuthi ube yi-barium sulfate encibilikayo ephansi.
Ama-opharetha kufanele agqoke izifihla-buso zothuli ezizilungisayo, izibuko zokuphepha kwamakhemikhali, izingubo zokuvikela amakhemikhali, namagilavu ​​enjoloba. Ziqhelelanise nemithombo yomlilo nokushisa, futhi ukubhema kwenqatshelwe ngokuphelele emsebenzini. Sebenzisa amasistimu nemishini yokungenisa umoya engaqhumi. Gwema ukuthintana nama-oxidants, ama-asidi, nezisekelo, ikakhulukazi ngamanzi.
Igcinwe kupharafini kanye nopharafini owuketshezi, ipakishwe emabhodleleni engilazi avaliwe ukuze kungangeni moya, anesisindo senethi esingu-1kg ibhodlela ngalinye, bese igxiliswa emabhokisini enziwe ngokhuni ahlanganiswe neziphedi. Kufanele kube nelebula ecacile ethi “Izinto Ezivuthayo Ezixhumene Nomswakama” ephaketheni, enelebula lesibili elithi “Izinto Ezinobuthi”.
Gcina endaweni epholile, eyomile, futhi enomoya ongashi. Gcina kude nemithombo yokushisa nomlilo, vimbela umswakama, futhi uvimbele ukulimala kweziqukathi. Ungahlangani namanzi, i-asidi, noma ama-oxidants. Ihlukaniswe nezinto eziphilayo, izinto ezivuthayo, nezinto ezifakwa kalula oksijini ukuze zigcinwe futhi zithuthwe, futhi azikwazi ukuthuthwa ngezinsuku zemvula.
Uma kunomlilo, isihlabathi esomile, i-graphite powder eyomile noma isicisha-mlilo esomile singasetshenziswa ukucisha umlilo, futhi amanzi, igwebu, i-carbon dioxide noma i-halogenated hydrocarbon extinguishing agent (njenge-ejenti yokucima i-1211) ayivunyelwe.
