Barium yog Alkaline Lub Ntiaj Teb Hlau Khoom, lub caij nyoog thib rau lub caij nyoog ntawm pawg Iia nyob rau hauv lub rooj ntu, thiab lub caij nquag nyob rau hauv lub ntiaj teb alkaline hlau.
1, cov ntsiab lus xa tawm
Barium, zoo li lwm lub ntiaj teb alkaline cov hlau, tau faib txhua qhov chaw nyob rau hauv lub ntiaj teb: cov ntsiab lus nyob rau hauv lub sab sauv crust yog 0.026%, thaum tus nqi nruab nrab hauv lub crust yog 0.022%. Lub Barium tsuas muaj nyob rau hauv daim ntawv ntawm cov chaw barite, sulfate lossis carbonate.
Cov zaub mov tseem ceeb ntawm barium nyob rau hauv qhov yog barite (baso4) thiab witherite (baco3). Cov chaw khaws nyiaj txiag ua tau dav, nrog cov nyiaj loj hauv Hunan, Guangxi, Shandong thiab lwm qhov chaw nyob hauv Suav teb.
2, daim ntawv thov teb
1. Kev Siv Siv
Nws yog siv rau kev ua cov ntsev barlium, alloys, foob pob hluav taws, nuclear reactors, thiab lwm yam kuj yog ib tus deepizer zoo heev rau kev kho tus tooj liab zoo heev.
Nws yog dav siv nyob rau hauv alloys, xws li cov txhuas, calcium, magnesium, sodium, lithium, txhuas thiab npib tsib xee.
Barium hlauYuav siv tau los ua cov neeg sawv cev Degassing rau kev tshem tawm cov roj av hauv lub tshuab nqus tsev thiab cov duab hlab, thiab degassing tus neeg saib xyuas rau cov hlau ua kom zoo nkauj.
Barium nitrate tov nrog poov tshuaj chloror, magnesium hmoov thiab rosin yuav siv tau los ua teeb liab foob pob thiab foob pob hluav taws.
Soluble Barium cov ntsiab sib txuas yog feem ntau siv ua tshuaj tua kab, xws li barium chloride, kom tswj tau ntau yam nroj tsuag kab.
Nws kuj tseem tuaj yeem siv rau kev kho kom zoo nkauj brine thiab boiler dej rau electrolytic caustic caustic Soda ntau lawm.
Nws tseem siv los npaj cov xim. Textile thiab Tawv Industomies tau siv ua mordant thiab rayon patting tus neeg sawv cev.
2. Kev Kho Mob Siv
Barium sulfate yog tshuaj pab yeeb tshuaj rau xoo hluav taws xob. Cov hmoov dawb dawb uas tsis muaj ntxhiab tsw thiab tsw, uas tuaj yeem muab kev sib piv zoo hauv lub cev thaum lub sijhawm kuaj lub ntsej muag xoo. Kev kho mob barium sulfate tsis tau nqus hauv txoj hnyuv plab zom mov thiab tsis muaj kev ua xua. Nws tsis muaj soluble barium sib txuas xws li barium chloride, barium sulfide thiab barsim carbonate. Nws yog tsuas yog siv rau cov plab zom mov irmography thiab qee zaum rau lwm lub hom phiaj.
3,Kev npaj txoj kev
Hauv kev lag luam, kev npaj ntawm Barium hlau tau muab faib ua ob kauj ruam: kev npaj ntawm barium thermal txo (alle hlau thermal txo).
Thaum 1000 ~ 1200 ℃, ob txoj kev tawm tsam no tsuas yog ua ib qho me me ntawm Barium me me. Yog li ntawd, lub tshuab nqus tsev yuav tsum tau siv los hloov chaw mos txwv tsis tu ncua los ntawm thaj chaw tiv thaiv kom zoo kom cov tshuaj tiv thaiv no tuaj yeem txuas ntxiv mus rau sab xis. Cov seem tom qab cov tshuaj xyuas yog tshuaj lom thiab tuaj yeem muab pov tseg tom qab kev kho mob.
4,Kev Nyab Xeeb Kev Nyab Xeeb
1. Kev Noj Qab Haus Huv
Barium tsis yog qhov tseem ceeb rau tib neeg, tab sis lub caij lom. Noj cov soluble barium sib txuas yuav ua rau barium lom. Piv txwv tias qhov hnyav nruab nrab ntawm ib tus neeg laus yog 70kg, tag nrho cov nyiaj ntawm Barium hauv nws lub cev yog li 16mg. Tom qab noj cov ntsev ntsev los ntawm kev ua yuam kev, nws yuav yaj los ntawm dej thiab lub plab acid, uas tau ua rau muaj mob ntau thiab qee qhov kev tuag.
Symptoms of acute barium salt poisoning: barium salt poisoning is mainly manifested as gastrointestinal irritation and hypokalemia syndrome, such as nausea, vomiting, abdominal pain, diarrhea, quadriplegia, myocardial involvement, respiratory muscle paralysis, etc. Such patients are easily misdiagnosed because they have gastrointestinal symptoms such as vomiting, abdominal pain, diarrhea, etc., and are easily misdiagnosed as food poisoning in the case of collective disease, and acute gastroenteritis in the case of single disease.
2. Kev Tiv Thaiv Kev Nyab Xeeb
Kev haus dej ceev ceev
Cais tawm thaj chaw tsis pub thiab kev txwv tsis pub nkag mus. Txiav tawm qhov chaw tiv thaiv. Nws raug nquahu tias cov neeg ua haujlwm kho xwm ceev hnav cov khaub ncaws hmoov lim thiab hluav taws kub tiv thaiv. Tsis txhob tiv tauj kom to feakage. Cov dej xau me me: Zam kom muaj plua plav thiab sau nws rau hauv ib lub taub ntim qhuav, ntxuav thiab npog kom huv. Hloov chaw rov ua dua tshiab. Cov dej xau loj: Npog nrog ntaub yas thiab cov ntaub qhwv kom txo tau ya. Siv cov cuab yeej tsis hloov pauv thiab rov ua dua tshiab.
3. Kev tiv thaiv kev ntsuas
Yuav tsum muaj kev tiv thaiv ua pa: feem ntau, tsis muaj kev tiv thaiv tshwj xeeb, tab sis nws raug nquahu kom hnav tus kheej cov plaub hau plua plav nyob rau hauv cov xwm txheej tshwj xeeb.
Kev tiv thaiv qhov muag: hnav cov tshuaj pleev xim rau kev nyab xeeb.
Kev tiv thaiv lub cev: hnav cov khaub ncaws tiv thaiv khaub ncaws.
Tes tiv thaiv: Hnav hnab looj tes roj hmab.
Lwm tus: yog txwv tsis pub nyob ntawm qhov chaw ua haujlwm. Them sai sai rau kev nyiam huv tus kheej.
5, Cia thiab tsheb thauj mus los
Muab cia rau hauv lub tsev rau khoom txias thiab muaj cua sov. Kom deb ntawm knling thiab cua sov. Cov txheeb ze cov av noo yog nyob hauv qab 75%. Pob ntawv yuav tsum raug kaw thiab yuav tsis muaj kev sib cuag nrog huab cua. Nws yuav tsum tau muab cais cais los ntawm oxidants, acids, alkalis, thiab lwm yam, thiab yuav tsum tsis txhob sib xyaw. Tawg-pov thawj teeb pom kev zoo thiab cov pa hluav taws xob yuav tsum tau saws. Nws yog txwv tsis pub siv cov cuab yeej siv neeg thiab cov cuab yeej uas yooj yim los tsim cov khoom plig. Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to.
