(1) Ukulungiswa kwe-barium oxide
I-ore ephezulu ye-bar kufuneka iqale ikhutshwe ngesandla kwaye idashwe, kwaye ke intsimbi kwaye i-silicon isuswe ukufumana ukugxila kune-96% ye-barium ye-barium ye-bali. I-ore powder enelungelo elingaphantsi kwe-20 mesh ixutywe ne-Coal okanye i-petroleum cooke powder kumyinge we-4: 1, kwaye ihlawulwe kwi-1100 ye-reverberatory ye-verberatory. I-barium ye-balium incitshisiwe kwi-barium sulfide (eyaziwa ngokuba "yi-ash emnyama"), kunye nesisombululo esifunekileyo se-barium selfiide sikhutshwe ngamanzi ashushu. Ukwenzela ukuguqula i-barium sulfide ibe yi-Barium Sulbontetity, i-sodium carbonate okanye i-carbon diokside kufuneka yongezwe kwisisombululo se-barium sulfide. I-Barium Oxide inokufunyanwa ngokuxuba i-barbonate ene-carbon powder kwaye ibaluke ngaphezulu kwe-800 ℃. Kufuneka kuqatshelwe ukuba i-Barium Oxide i-oxid inyanzelekile ukuba ibulale i-Barium Peroxide nge-500-700 ℃, kunye ne-Barium Peroxide inokungathanjiswanga kwi-700-800 ℃. Ke ngoko, ukuphepha ukuveliswa kwe-Barium Peroxide, imveliso ebhaliweyo kufuneka ipholelwe okanye icinywe phantsi kokhuseleko lwerhasi ye-intert.
.
Ngenxa yezithako ezahlukeneyo, zimbini iindlela ze-aluminium zokunciphisa i-barium oxim
6BA + 2l → 3Bao • Al23o3 + 3ba ↑
Okanye: 4Bao + 2al → Bao • Al23 + 3ba ↑
Kwi-1000-1200 ℃, ezi ndlela zimbini zinika i-barium incinci kakhulu, ke impompo ye-vacuum iyafuneka ukuqhubeka udlulisele kwindawo yokuphendula kwindawo yokuphendula ukuze impendulo iqhubeke nokusekunene. Intsalela emva kokuba impendulo iyityhefu kwaye kufuneka inyangwe ngaphambi kokuba ilahliwe.
Ukulungiswa kweenkanzi eziqhelekileyo zebarium
(1) Indlela yokulungiselela yeBarium Carbonate
Indlela yokunyanzelwa kwe-carbonis
Eyona ndlela yekharbhonizal ikakhulu ibandakanya ukudibanisa i-bar kunye ne-Coal kwinxalenye ethile, ityumze kwi-chill ejikelezayo kunye nokubala kunye nokucutha nge-1100-1200 ℃ ukufumana ilokhwe ye-barium ℃ ukufumana ilokhwe ye-Barium ye-Barium ye-sulfide. I-carbon diokside yaziswa kwisisombululo se-barium ye-barfide yekhalifa, kwaye impendulo yile ilandelayo:
I-BAS + CO2 + H2O = baco3 + h2s
I-carbonate efunyenweyo ye-Barium Carbonate Sliel isuswe, ihlanjwe kwaye ihlaselwe i-vacuum, kwaye emva koko yomile kwaye ityumke kwimveliso engama-300 ukufumana imveliso ye-carium ye-carium. Le ndlela ilula kwinkqubo kwaye iphantsi ngeendleko, ngenxa yoko yamkelwa ngabavelisi kakhulu.
② Indlela yokuphola kabini
I-Barium ye-Barium ye-Barium kunye ne-Ammonium Carbonate yahlala isebenza kabini indlela yokuphendula, kwaye impendulo yile ilandelayo:
Bas + (NH4) 2Co3 = baco3 + (NH4) 2s
Okanye i-barium chloride ye-bides ene-potassium carbonate, kwaye impendulo yile ilandelayo:
I-Bacl2 + K2co3 = baco3 + 2kcl
Imveliso efunyenwe kwimpendulo ihlanjwe, ihlanjululwe, yomile, njl njl.
Indlela ye-barium carbonate
I-Barium Carbonate Powder iphendulwa kunye netyuwa ye-Ammonium ukuba ivelise ityiwa yetywili, kwaye i-Ammonate ikharbonate iphinde isebenze kwakhona. I-Issocium yeSocium yeSocium yongezwa kwi-Ammonate ye-Amon Carbonate ukuya kuthintela i-Barium ye-Barium Carbonate, eyahluliweyo kwaye yomile ukwenza imveliso egqityiweyo. Ukongeza, utywala botywala obufunyenweyo bunokuphinda busebenze kwakhona. Indlela yokusabela yile ilandelayo:
I-Baco3 + 2HCL = i-bacl2 + h2o + co2
I-Bacl2 + 2NH4H = ba (oh) 2 + 2nh4cl
Ba (oh) 2 + CO2 = i-baco3 + h2o
(2) Indlela yokulungiselela ye-Barium Titatate
① indlela yesigaba esiqinileyo
I-Barium Titanate inokufumaneka ngokubandakanya iBarium Carbonate kunye neTitanium Dioxide, kwaye naziphi na izinto ezinokufunyanwa kuyo. Indlela yokusabela yile ilandelayo:
I-tio2 + baco3 = i-biatio3 + co2 ↑
Indlela yokufota
I-Barium Cbride kunye neTitanium Tetracheride ixutywe kwaye inyibilikisiwe kwiimali ezilinganayo, ifuduseza kwi-70 ° C, kwaye emva koko ihlanjwe yi-oxtanyl oxilet, ehlanjwayo, kwaye emva koko i-pyrolyzed ukufumana i-barium izishumi. Indlela yokusabela yile ilandelayo:
I-Bacl2 + iTiki4 + 2h2c2o4 + 5H2O = i-BOO4 +
I-BOTIO (C24) 2 • I-4h2o = I-BIOO = BHALA 3 + 2CO ↑ + 2CO ↑ + 4h2o
Emva kokubetha i-Itatitanic Acid, isisombululo se-birium chloride yongezwa, kwaye emva koko i-Ammonate yongezwa phantsi kongezwe ukuvelisa i-carbonate ye-barbonate kunye ne-metitanic acid, enamachaphaza emveliso. Indlela yokusabela yile ilandelayo:
I-Bacl2 + (NH4) 2Co3 = baco3 + 2nh4cl
H2ITO3 + i-baco3 = i-biatio3 + CO2 ↑ + h2o
(3) Ukulungiswa kwe-barium chloride
Inkqubo yemveliso ye-Barium Cbride ikakhulu ibandakanya indlela ye-hydrochloric acid, indlela ye-Barium Chilbonate, indlela ye-calcium ye-calcium, i-calcoride indlela yendlela eyahlukeneyo okanye izinto ezingafunekiyo.
① Indlela ye-acid ye-hydrochloric. Xa i-barium sulfide inyangwa nge-hydrochloric acid, eyona ndlela iphambili yile:
I-BAS + 2HCI = BACL2 + H2S ↑ + Q
Indlela ye-carbonate ye-②barium. Yenziwe nge-Barium Carbonate (I-Barium Carbonate) njengezixhobo eziluhlaza, ukuphendula okuphambili:
I-Baco3 + 2HCI = BACL2 + CO2 ↑ + h2o
Indlela yokusebenzela
Iziphumo zeBharimu kwiMpilo yoLuntu
I-Barium ichaphazela njani impilo?
I-Barium ayisiyonto ibalulekileyo emzimbeni womntu, kodwa inefuthe elikhulu kwimpilo yabantu. I-Barium inokuvezwa yi-Barium ngexesha le-Barium Mining Ling, ukunyibilikisa, ukuvelisa, kunye nokusetyenziswa kweendebe zebarrium. I-Barium kunye neekhomputha zayo zinokungena emzimbeni ngephecana lokuphefumla, ukugaya itrayiti, kunye nolusu olonakeleyo. Ityhefu ye-Barium yeBharimu ibangelwa ikakhulu kukuphefumla okuphefumla, okwenzeka kwiingozi ngexesha lokuvelisa kunye nokusetyenziswa; Ityhefu engasebenziyo ye-Barium ibangelwa kukuhamba kwe-digrinity, uninzi olubangelwa kukungeniswa ngengozi; I-Liquizile ye-FalIimu enyibilikisiweyo inokungeniswa kulusu obenzekileyo. Ityhefu yetyhefu ye-barium ibangelwa kukungabikho kwengozi.
Ukusetyenziswa kwezonyango
(1) I-Barium Span Racography
I-Barium Spaniography, ekwabizwa ngokuba yi-dict ye-digim ract, yindlela yoviwo esebenzisa i-barium ye-rulfate njengommeli we-risium njengommeli weqonga eliphantsi kwe-x-ray iqumrhu. I-Barium Sok Ricophography i-radiology yomlomo yokwahlulahlula, kunye ne-chiemul barlinal ye-gesium esetyenzisiweyo njenge-Insultor ye-gecosa, ngenxa yoko ingeyongozi ebantwini.
Ngokweemfuno zonyango lweklinikhi kunye nonyango, i-gestrointentinal yesidlo se-radium ye-gestrointenal inokwahlulwa kwi-Gastroight Sid, i-GestroilinTestinal ye-GestroilinTestinal, i-Colon Bagium Ene kunye ne-Enerium ye-Ene kunye ne-Enemaimu kunye ne-Enerium ye-Ene.
Ityhefu ye-barium
Iindlela zokuvezwa
I-Barium inokuvezwaibangaNgexesha lokugoba, ukunyibilika, kunye nemveliso. Ukongeza, i-barium kunye nemichiza yayo isetyenziswa ngokubanzi. Iityuwa eziqhelekileyo eziyityhefu zibandakanya i-Barium Carbonate, i-barium cloride, i-barium sulfide, i-barium ye-Barium Nitrate kunye ne-Barium Oxide. Ezinye izinto zemihla ngemihla nazo zine-Barium, njenge-Barium Sulfide kwiinwele zokususwa kweenwele. Ezinye iiarhente zolawulo lwezinambuzane zezolimo okanye irodentides zikwanazo neebhanti ezinyibilikayo ezifana ne-barium ye-dirium ye-dirium kunye nebarium carbonate.
