Ifomula yolwakhiwo:Ba
【 Ubunzima beMolekyuli】137.33
[IiPropati zoMzi kunye nezeMichiza] isilivere etyheli emhlophe yentsimbi ethambileyo. Uxinzelelo olunxulumeneyo yi-3.62, indawo yokunyibilika yi-725 ℃, iqondo lokubila yi-1640 ℃. Ityhubhikhi egxile kumzimba: α=0.5025nm. Ubushushu obunyibilikayo 7.66kJ/mol, ubushushu be-vaporization 149.20kJ/mol, uxinzelelo lomphunga 0.00133kpa (629 ℃), 1.33kPa (1050 ℃), 101.3kPa (1640 ℃), ukumelana ne-29Ω2. I-Ba2 + ine-radius ye-0.143nm kunye ne-thermal conductivity ye-18.4 (25 ℃) W / (m · K). I-coefficient yokwandiswa komgca 1.85 × 10-5 m/(M ·℃). Kwiqondo lobushushu begumbi, isabela ngokulula emanzini ukukhupha igesi yehydrogen, enyibilika kancinane etywaleni kwaye inganyibiliki kwibenzene.
[Imigangatho yoBulunga]ImiGangatho yeeReferensi
【 Isicelo】Isetyenziswe ngokubanzi kwi-alloys ye-degassing, kuquka i-lead, i-calcium, i-magnesium, i-sodium, i-lithium, i-aluminium, kunye ne-nickel alloys. Isetyenziswa njengento yokucinezela irhasi ukususa umkhondo werhasi eziseleyo kwiityhubhu zevacuum ezingenazingcingo, kwaye zikwasetyenziselwa ukuveliswa kweetyuwa ze-barium.
Indlela yokunciphisa i-Aluminiyam ye-thermal: I-nitrate ye-Barium ichithwa ngokushisa ukuvelisa i-barium oxide. I-aluminium ene-fine grained isetyenziswe njenge-arhente yokunciphisa, kwaye umlinganiselo wezithako ngu-3BaO: 2A1. I-Barium oxide kunye ne-aluminiyam zenziwa kuqala kwiipellets, ezithi ke zibekwe kwindawo epholileyo kwaye zifudunyezwe ukuya kwi-1150 ℃ ukunciphisa ukucocwa kwe-distillation. Ukucoceka kwe-barium okubangelwa yi-99%.
【 Ukhuseleko】Uthuli luthanda ukutsha oluzenzekelayo kwiqondo lobushushu begumbi kwaye lunokubangela ukutsha kunye nogqabhuko-dubulo xa lusesichengeni sobushushu, amadangatye, okanye kutshintsho lwemichiza. Iyakwazi ukubola kwamanzi kwaye isabela ngobundlobongela kunye ne-acids, ikhupha igesi ye-hydrogen enokuthi ivuthwe ngubushushu bokuphendula. Ukudibana ne-fluorine, i-chlorine, kunye nezinye izinto kunokubangela ukusabela kweekhemikhali ezinobundlobongela. Isinyithi se-Barium siphendulana namanzi ukwenza i-barium hydroxide, enefuthe elonakalisayo. Kwangaxeshanye, iityuwa ze-barium ezinyibilikayo emanzini zinetyhefu kakhulu. Le nto inokuba yingozi kokusingqongileyo, kuyacetyiswa ukuba ungayivumeli ukuba ingene kwindawo.
Ikhowudi yengozi: Into enokutsha xa idibana nokufuma. GB 4.3 Udidi lwe-43009. UN No. 1400. I-IMDG CODE 4332 iphepha, iKlasi 4.3.
Xa uyithatha ngephutha, sela amanzi amaninzi afudumeleyo, wenze ukuhlanza, uhlambe isisu nge-2% ukuya kwi-5% yesisombululo se-sodium sulfate, ubangele isifo sohudo, kwaye ufune unyango. Ukusezela uthuli kunokubangela ityhefu. Izigulane kufuneka zikhutshwe kwindawo engcolileyo, ziphumle, kwaye zigcinwe zifudumele; Ukuba ukuphefumla kuyeka, khawuleza wenze ukuphefumla okwenziweyo kwaye ufune unyango. Ukutshiza ngengozi emehlweni, hlambulula ngamanzi amaninzi, funa unyango kwiimeko ezinzima. Ukudibana nolusu: Hlamba ngamanzi kuqala, emva koko uhlambe ngokucokisekileyo ngesepha. Ukuba kukho ukutsha, funa unyango. Ngoko nangoko, hlambulula umlomo wakho ukuba utyiwe ngempazamo kwaye ufune unyango ngokukhawuleza.
Xa uphatha i-barium, kuyimfuneko ukuqinisa amanyathelo okukhusela okhuseleko lwabaqhubi. Yonke inkunkuma kufuneka iphathwe nge-ferrous sulfate okanye i-sodium sulfate ukuguqula iityuwa ze-barium eziyityhefu zibe yi-solubility ephantsi ye-barium sulfate.
Abanini-zithuthi kufuneka banxibe iimaski zothuli ezizilungisayo, iiglasi zokhuseleko lwekhemikhali, iimpahla ezikhuselayo zeekhemikhali, kunye neeglavu zerabha. Zigcine kude nemithombo yomlilo nobushushu, kwaye ukutshaya akuvumelekanga ngokungqongqo kwindawo yokusebenzela. Sebenzisa izixhobo zokungenisa umoya ezingagqabhukiyo kunye nezixhobo. Kuphephe ukudibana nee-oxidants, iiasidi, kunye neziseko, ngakumbi ngamanzi.
Igcinwe kwiparafini kunye neparafini engamanzi, ipakishwe kwiibhotile zeglasi ezivaliweyo zingangeni moya, ezinobunzima obuyi-1kg ngebhotile, ze emva koko zigxininiswe kwiibhokisi zomthi eziqatywe ngepadding. Kufuneka kubekho iileyibhile ezicacileyo "Izinto ezinokutsha eziQhagamshelana noBumanzi" kwipakethe, kunye neleyibhile yesibini ye "Toxic Substances".
Gcina kwindawo epholileyo, eyomileyo, nengena umoya wesitora enokutsha. Gcina kude nobushushu kunye nemithombo yomlilo, thintela ukufuma, kwaye uthintele umonakalo wesikhongozeli. Musa ukudibana namanzi, iasidi, okanye ii-oxidants. Yahlulwe kwizinto eziphilayo, izinto ezinokutsha, kunye nezinto ezinokuthi zifakwe kwi-oxidizable ngokulula ukuze zigcinwe kwaye zithuthwe, kwaye azikwazi ukuthuthwa ngeentsuku zemvula.
Kwimeko yomlilo, isanti eyomileyo, i-graphite powder eyomileyo okanye i-powder extinguisher eyomileyo ingasetyenziselwa ukucima umlilo, kwaye amanzi, i-foam, i-carbon dioxide okanye i-halogenated hydrocarbon ecima i-agent (njenge-agent ye-1211 yokucima) ayivumelekanga.
