Kev siv:.Lanthhanum carbonateyog cov sib xyaw ua ke inorganic composed ntawm Lanthhanum caij thiab Carbonate ion. Nws yog tus cwj pwm los ntawm muaj zog ruaj khov, qis solubility thiab nquag tshuaj tshuaj. Hauv kev lag luam, lanthhanum carbonate tuaj yeem yog siv dav hauv ceramics, cov khoom siv hluav taws xob, tshuaj thiab lwm thaj teb. Ntawm lawv, lanthhanum carbonate ua lub luag haujlwm tseem ceeb hauv kev lag luam ceramics, tuaj yeem siv ua xim, iav ntxiv, thiab lwm yam; Nyob rau hauv daim teb hluav taws xob, Lanthhanum carbonate tuaj yeem npaj nrog cov khoom siv hluav taws xob muaj zog, siv rau kev tsim cov khoom siv hluav taws xob muaj zog, cemented carbide additives; nyob rau hauv daim teb ntawm cov kws tshuaj,Lanthhanum CarbonatePuas yog ib qho kev ntxiv rau cov tshuaj, thiab tuaj yeem siv los kho hauv thaj chaw ntawm cov tshuaj,Lanthhanum Carbonateyog ib hom tshuaj ntxiv, uas tuaj yeem siv rau kev kho mob hypercalcemia, hemolytic urement procitly suremholdemia nyob rau hauv kawg mob raum cov neeg mob raum. Nyob rau hauv ib lo lus,Lanthhanum CarbonateMuaj ntau lub zog thiab tau siv dav hauv kev lag luam niaj hnub, cov khoom siv science, tshuaj thiab lwm thaj teb.

Yam ntim: 25, 50 / kg, 1000kg / tonne hauv woven hnab, 25, 50kg / chim / chim nyob rau hauv Cardboard nruas.

Yuav Ua Li Cas:

Lanthhanum carbonateyog lub ntsiab sib txuas rau kev tsim cov lus Lanthhanbe [1-4]. Nrog rau qhov teeb meem ceev ceev ntawm ib puag ncig, ammonium bicarbonate, tau tsuas yog siv cov kev lag luam ntawm cov neeg siv khoom lag luam tsis muaj nqi thiab cov tshuab hloog qis ntawm cov carbonate tau txais. Txawm li cas los xij, vim lub eutrophication ntawm NH + 4 nyob rau hauv kev lag luam dej khib nyiab, uas muaj kev cuam tshuam ntau ntxiv rau ib puag ncig, cov neeg ammonium tau siv hauv kev lag luam tau muab tso rau pem hauv ntej ntau txoj kev xav tau. Raws li ib qho ntawm cov neeg tsis muaj zog, sodium carbonate, piv nrog ammonium bicarbonate, nyob rau hauv kev npaj ntawmLanthhanum Carbonate In Tus txheej txheem ntawm kev siv dej khib nyiab tsis muaj tshuaj ammonia, nitrogen impurities, yooj yim rau kev cuam tshuam nrog; Piv nrog sodium bicarbonate, haum rau ib puag ncig muaj zog [8 ~ 11].Lanthhanum carbonatenrog sodium carbonate raws li kev npaj ntawm tsawg-soder Earbonate yog tsis tshua muaj nqi tshaj tawm hauv cov qauv pub dawb nag lossis daus, thiab qis sodiumLanthhanum Carbonateyog npaj los ntawm kev tswj hwm cov txheej txheem ntawm cov tshuaj tiv thaiv.

Ceev faj rau kev thauj mus los ntawmLanthhanum Carbonate: Tsheb thauj mus los nrog hom uas tsim nyog thiab cov khoom siv dej kom muaj xwm ceev. Nws yog nruj me ntsis txwv tsis pub sib xyaw thiab thauj nrog cov oxidizers thiab cov tshuaj uas muaj kuab. Cov pa tawm huv ntawm lub tsheb thauj khoom uas yuav tsum tau nruab nrog nplaim retardant. Thaum tanker cov tsheb thauj khoom siv rau kev thauj mus los, av chains yuav tsum muab ntsia. Txhawm rau kom txo cov hluav taws xob zoo li qub tsim los ntawm kev co los ntawm kev co, nws yog qhov ua tau rau nruab qhov qhov dividers hauv lub tank. Nws yog txwv tsis pub thauj lossis tsis thauj khoom siv cov khoom siv kho txhua yam thiab cov cuab yeej uas muaj feem cuam tshuam rau txim taws. Nyob rau hauv lub caij ntuj sov sawv ntxov thiab yav tsaus ntuj yog qhov zoo, hauv cov txheej txheem thauj, kom tiv thaiv hnub thiab nag thiab kub. Txav deb ntawm hluav taws qhov chaw, cua sov qhov chaw nruab nrab thaum nres nres. Tsheb thauj mus los yuav tsum tau nqa tawm raws li cov kev ua haujlwm, thiab yuav tsum tsis txhob tsum rau thaj chaw thaj chaw thiab cov pej xeem muaj ntau. Kev tsheb ciav hlau kev tsheb thauj mus los yog txwv los ntawm kev hla kev. Bulk thauj mus los ntawm cov ntoo lossis cov nkoj maj mam txwv tsis pub muaj. Cov paib kev phom sij thiab cov ntawv ceeb toom yuav tsum tau tshaj tawm rau hauv txoj kev thauj mus los raws li kev thauj mus los.
