【Kulemera kwa Culecular】137.33
[Zathupi ndi mankhwala] chitsulo chofewa chofewa. Kuchulukitsa Kwambiri 3.62, kusungunuka kokhazikika 725 ℃, kuwiritsa mpaka 1640 ℃. Cubic yapamwamba ya thupi: α = 0.5025nm. Kusungunula kutentha 7.66kj / Mol, Vapoririza kutentha 149.20KJ / mamol, opsinjika (62.33kpa (629 ℃), 1050 ℃), 1050 ℃), 1050 ℃), 1013 Ba2 + ali ndi radius wa 0.143nm ndi mawonekedwe a 18,4 (25 ℃) w / (mu ·). Kukula kwa mzere 1.85 × 10-5 m / (mu℃). Kutentha, kumatenga mosavuta ndi madzi kuti amasule mpweya wa hydrogen, womwe umasungunuka pang'ono ndi mowa.
[Miyezo Yabwino]Miyezo
【Kugwiritsa ntchito】Kugwiritsidwa ntchito kwambiri pakugalikira Kugwiritsa ntchito ngati wopondereza gasi kuti achotse mpweya wotsalira mati abuluu a vabuum valuum, komanso amagwiritsidwanso ntchito popanga barium mchere.
Njira yochepetsera mafuta a aluminium. Barum nitrate amasungunulidwa kuti apange barium oxide. Aluminiyamu abwino otupa amagwiritsidwa ntchito ngati wothandizira wothandizira, ndipo kuchuluka kwa zosakaniza ndi 3bao: 2A1. Barum oxide ndi aluminium adayamba kupanga ma pellets, omwe amaikidwabe ndikuwotcha mpaka 1150 ℃ kuti achepetse kutsuka kochepa. Kuyera kwa barium ndi 99%.
【Chitetezo】Fumbi limakonda kuyaka motakata firiji ndipo imatha kuwononga mocheka ndikuphulika mukamawaza kutentha, malawi, kapena zochita zamankhwala. Kukonda kuwonongeka kwa madzi ndikuchita zachiwawa ndi asidi, kumasula mpweya wa hydrogen komwe kumatha kuyatsidwa ndi kutentha kwa zomwe zimachitika. Kukumana ndi fluorine, chlorine, ndi zinthu zina kungayambitse zomwe mwachita zachiwawa. Barbium zitsulo zimakhudzana ndi madzi kuti apange barium hydroxide, yomwe ili ndi zotsatira zoyipa. Nthawi yomweyo, mchere wosungunuka madzi ndi woopsa kwambiri. Zinthuzi zitha kukhala zovulaza ku chilengedwe, tikulimbikitsidwa kuti musayike chilengedwe.
Khodi yowopsa: chinthu choyaka polumikizana ndi chinyezi. GB 4.3 Class 43009. UN No. 1400. IMDG Code 4332 Tsamba 4332 Tsamba, kalasi 4.3.
Mukamatenga molakwika, imwani madzi ambiri ofunda, kusanza m'mimba, sambani m'mimba ndi 5% sodium sulfate yankho, ndipo pitani kuchipatala. Kupuma kwa fumbi kumatha kuyambitsa poyizoni. Odwala ayenera kuchotsedwa m'dera loyipitsidwa, kupumula, ndi kutentha; Ngati kupuma kumasiya, nthawi yomweyo kupuma ndi kupendekera kuchipatala. Mwangozi wowunjika m'maso, nadzatsuka ndi madzi ambiri, kufunafuna chithandizo chamankhwala moopsa. Pakhungu: Muzimutsuka ndi madzi kaye, ndiye kuti muzisamba moyenera ndi sopo. Ngati pali kuwotcha, kukafuna chithandizo chamankhwala. Nthawi yomweyo muzimutsuka pakamwa panu ngati mungapeze cholakwika ndi chithandizo chofunikira kwambiri.
Mukamayendetsa barium, ndikofunikira kulimbitsa chitetezo chotetezedwa cha chitetezo. Zowonongeka zonse ziyenera kuthandizidwa ndi sulfate ya sulfate kapena sodium sulfate kusinthitsa suxric bartic mchere mu sulfate yotsika.
Ogwiritsa ntchito ayenera kuvala zosefera zodzikongoletsera, mabowo oteteza mankhwala, zovala zoteteza zamankhwala, ndi magolovesi a mphira. Pewani magwero amoto ndi kutentha, ndipo kusuta kumaletsedwa kuntchito. Gwiritsani ntchito ma mpweya ophulika ophulika ndi zida. Pewani kulumikizana ndi oxidants, ma acid, ndi zitsulo, makamaka ndi madzi.
Sungani ku Kerosene ndi Madzimadzi amadzimadzi okhala ndi mabotolo agalasi okhala ndi mabotolo a urtightivene, ndi kulemera kwa 1kg pa botolo, kenako ndikuyang'ana m'matabwa. Payenera kukhala pali "zinthu zoyaka zokhudzana ndi chinyezi" kulembera patsamba, ndi zinthu zachiwiri za "zinthu zopweteka".
Sungani pamalo ozizira, owuma, komanso mpweya wabwino wonyamula katundu. Pewani kutentha ndi zokutira moto, pewani chinyezi, ndipo pewani kuwonongeka. Osamalumikizana ndi madzi, asidi, kapena oxidants. Olekanitsidwa ndi zinthu zachilengedwe, ziyambuzi, komanso zinthu mosavuta zosungira ndi mayendedwe, ndipo sizingayendetsedwe pakadutsa masiku amvula.
Pankhani yamoto, mchenga wouma, wowuma wa graphite kapena madzi owuma amatha kuzimitsa moto, ndipo madzi owuma, mpweya wabwino kwambiri.
