【Isisindo】137.33
[Izakhiwo ezingokomzimba nezamakhemikhali] I-Yellow Sight White Metal. Ukuncipha okuhlobene 3.62, Iphuzu Lokuncibilikisa 725 ℃, Iphuzu elibilayo 1640 ℃. I-Cubic egxile emzimbeni: α = 0.5025nm. I-Melting Heat 7.66kj / Mol, Vaporization Heat 149.20KJ / Mol, Vapor Pressure 0.00133kpa (1013kpa (1613 ω), i-1013 ω), I-BA2 + ine-radius ka-0.143NM kanye nokuvuselelwa okushisayo kuka-18.4 (25 ℃) W / (m · k). Ukunwetshwa komugqa we-Linear Expeansion 1.85 × 10-5 m / (m ℃). Emazingeni okushisa ekamelo, kuphendula kalula ngamanzi ukukhulula igesi ye-hydrogen, okuncibilikayo kancane ngotshwala nokungabonakali e-benzene.
[Izindinganiso zekhwalithi]Izinga lereferensi
【Kusetshenziswe kabanzi kuma-algassing Alloys, kufaka phakathi ukuhola, i-calcium, i-magnesium, i-sodium, i-lithium, i-aluminium, kanye nama-nickel alloys. Kusetshenziswe njenge-suppress yegesi ukuze ususe ukulandelela amagesi asasele kumashubhu we-vacuum engenantambo, futhi futhi esetshenziswa ekukhiqizweni kosawoti we-barium.
Indlela yokunciphisa i-Aluminium I-aluminium ethosiwe enhle isetshenziswa njenge-ejenti eyengeziwe, futhi isilinganiso sezithako ngu-3bao: 2a1. IBarium Oxide ne-Aluminium kuqala kwenziwa ngama-pellets, abese esefakwa ku-1150 ℃ ngokuhlanzwa kokuncishiswa kwe-distillation. Ubumsulwa be-barium ephumela yi-99%.
Ukuphepha】Uthuli luthambekele ekushiseni okuzenzakalelayo emazingeni okushisa asekamelweni futhi kungadala ukuhlanganiswa nokuqhuma lapho kuvezwa ukushisa, amalangabi, noma ukusabela kwamakhemikhali. Kuthambekele ekuboleni kwamanzi futhi uphendule ngobudlova ngama-acid, ukukhulula igesi ye-hydrogen engaqokwa ngokushisa kokuphendula. Ukuhlangabezana nama-fluorine, chlorine, nezinye izinto kungadala ukusabela okunobudlova. I-Barium Metal iphendula ngamanzi ukwakha i-barium hydroxide, enomphumela osonakalisayo. Ngasikhathi sinye, usawoti we-barium ocibiliweyo anobuthi kakhulu. Le nto ingaba yingozi emvelweni, kunconywa ukuthi ungavumeli ukuthi ifake imvelo.
Ikhodi eyingozi: into evuthayo ekuxhumaneni nomswakama. GB 4.3 Class 43009. Un No. 1400. IMDG Code 4332 Ikhasi le-4332, class 4.3.
Lapho uthatha ngephutha, phuza amanzi amaningi afudumele, unxenxa ukugabha, geza isisu nge-2% kuya ku-5% sodium sulfate solution, uhudula. Uthuli lokuphefumula lungadala ubuthi. Iziguli kufanele zikhishwe endaweni engcolisiwe, ziphumule, futhi zigcinwe zifudumele; Uma ukuphefumula kumisa, ngokushesha kwenziwe ukuphefumula kokufakelwa futhi kufune ukwelashwa. Ngengozi ukugebha emehlweni, hlamba ngamanzi amaningi, funa ukwelashwa ezimweni ezinzima. Ukuxhumana kwesikhumba: Hlambulula ngamanzi kuqala, bese ugeza kahle ngensipho. Uma kukhona ukushiswa, funa ukwelashwa. Masinyane geza umlomo wakho uma ungeniswe ngephutha futhi usheshe ufune ukwelashwa.
Lapho uphatha i-barium, kuyadingeka ukuqinisa izindlela zokuvikela ukuphepha zabahlinzeki. Yonke imfucumfucu kufanele iphathwe nge-sulfate ye-ferrous noma i-sodium sulfate ukuguqula usawoti we-barium we-toxic waba sulubelity barium sulfate.
Ama-opharetha kufanele agqoke imaski yothuli yokuzibonakalisa, ama-googgles amakhemikhali, izingubo zokuvikela amakhemikhali, namagilavu ​​enjoloba. Gwema kude nemithombo yomlilo nokushisa, futhi ukubhema akuvunyelwe ngokuphelele emsebenzini. Sebenzisa amasistimu womoya wokuqhuma komoya wokuqhuma kwemishini. Gwema ukuxhumana ne-oxidants, ama-acid, nezisekelo, ikakhulukazi ngamanzi.
Kugcinwe ku-karafinin ne-paraffin ewuketshezi, kufakwe emabhodleleni engilazi anokuvalwa kokuzalwa kwezindiza, ngesisindo esine-1kg ngebhodlela le-1kg ngalinye, bese ligxila emabhokisini enkuni afakwe nge-padding. Kufanele kube nezinto ezicacile "ezivuthayo zithintana nelebuli yomswakama" kwi-apaning, ngelebula lesibili le- "anobuthi nto".
Gcina endaweni yokugcina epholile, eyomile, evuthayo evuthayo. Gwema kude nemithombo yokushisa kanye nomlilo, vimbela umswakama, futhi uvikele ukulimala kwesiqukathi. Musa ukuxhumana namanzi, acid, noma ama-oxidants. Ihlukaniswe kusuka ezintweni eziphilayo, ama-combustible, kanye nezinto ezingenazimo ezingenangqondo zokugcina nokuhamba, futhi akunakuhanjiswa ngezinsuku zemvula.
Uma kwenzeka umlilo, isihlabathi esomile, i-graphite eyomile noma eyomile ye-powder engahle isetshenziselwe ukucisha umlilo, namanzi, igwebu, isikhutha se-hydrocarbon ukucisha i-ejenti (njengo-1211 ocile i-ejenti) ayivunyelwe.
