Cov teeb meem tseem ceeb uas muaj nyob rau hauv Kev Txhim Kho Ntawm Tantalum Thiab Niobium Kev Lag Luam

Cov teeb meem tseem ceeb uas muaj nyob rau hauv txoj kev loj hlob ntawmtantalumthiab niobium kev lag luam

1. Cov teeb meem tiv thaiv ib puag ncig hauv kev lag luam tantalum thiab niobium. Tam sim no, kev lag luam tantalum thiab niobium ntsib teeb meem tshwm sim thiab xav daws nws, uas yog kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Yuav ua li cas nrog cov xov tooj cua slag tsim los ntawm smelting ntawm tantalum thiab niobium ore tau dhau los ua kev txhawj xeeb ntawm tag nrho kev lag luam. Ntawm lawv, Guangdong xeev xav kom khaws cia ib ntus ntawm lub tsev khaws khoom ib ntus, thiab tsis muaj kev daws teeb meem. Nyob rau tib lub sijhawm, nrog rau kev siv cov se ib puag ncig thiab kev tshuaj xyuas ib puag ncig, cov tuam txhab tau nce peev hauv kev tswj hwm ib puag ncig xws li kev pov tseg cov dej khib nyiab uas muaj fluoride.

Txij li thaum poov tshuaj fluorotantalate yog ib qho tshuaj txaus ntshai, cov tuam txhab uas tsim cov poov tshuaj fluorotantalate hauv kev lag luam tantalum-niobium yog tag nrho cov chaw tsim tshuaj lom neeg thiab yuav tsum tau ua raws li cov qauv kev tiv thaiv ib puag ncig thiab kev tswj hwm nruj dua. Ntawm lawv, qee lub tuam txhab hauv kev lag luam nrog cov txiaj ntsig tsis muaj zog thiab kev kub siab ntawm kev tiv thaiv ib puag ncig tau ntsib teeb meem ntawm kev tsiv chaw lossis txawm tias kaw. Nyob rau tib lub sijhawm, vim kev txhim kho ntawm kev tiv thaiv ib puag ncig, tus nqi tsim khoom lag luam tau nce, thiab tus nqi kom zoo dua tau txo qis thaum ntsib cov neeg sib tw txawv teb chaws.

2. Qhov teeb meem ntawm tantalum thiab niobium kev ruaj ntseg. Kev lag luam tantalum thiab niobium yog ob-kawg kev lag luam. Kev ruaj ntseg thiab kev thov cuam tshuam rau kev txhim kho ruaj khov ntawm tantalum thiab niobium kev lag luam. Cov yam ntxwv ntawm Tuam Tshoj tus tantalum thiab niobium mineral kev pab yog hais tias muaj ob peb loj ores, ob peb nplua nuj ores, thiab qib qis. Txawm li cas los xij, qib ntawm cov mines txawv teb chaws feem ntau yog siab dua 0.02%. Tam sim no, Tuam Tshoj txoj kev vam khom rau txawv teb chaws tantalum thiab niobium raw khoom tau mus txog ntau dua 80%. Kev ceev ceev ntawm tantalum thiab niobium raw cov ntaub ntawv tau txwv tsis pub cov khoom ntawm tantalum thiab niobium raw khoom. Tuam Tshoj txoj kev lag luam tantalum thiab niobium txuas ntxiv txhim kho kev noj qab haus huv. Nyob rau tib lub sij hawm, nyob rau hauv downstream daim ntaub ntawv, nrog rau qhov tshwm sim ntawm high-specific capacitance capacitors thiab lwm yam khoom, kev thov rau pej xeem daim ntawv thov tau poob qis.

3. Cov khoom yog concentrated nyob rau hauv nruab nrab mus rau qis-kawg. Nyob rau hauv xyoo tas los no, txawm hais tias Tuam Tshoj txoj kev lag luam tantalum thiab niobium tau ua qee yam kev vam meej hauv kev siv tshuab, nws cov khoom lag luam feem ntau yog tsom rau cov khoom qis kawg. Piv nrog rau nws cov kev sib tw thoob ntiaj teb, cov ntsiab lus kev kawm tsis siab, thiab muaj qee qhov sib txawv hauv cov nplai, thev naus laus zis thiab kev tsim kho tshiab. , tab sis vim yog vim li cas tus nqi, cov neeg muag khoom txawv teb chaws tau nce lawv cov kev yuav khoom ntawm cov khoom nruab nrab mus rau qis kawg uas tsim nyob rau hauv kuv lub teb chaws thiab txo lawv cov kev yuav khoom ntawm tantalum hlau rau capacitors. Qhov no muaj kev cuam tshuam zoo rau Tuam Tshoj cov khoom muaj nqis ntxiv thiab cuam tshuam rau cov txheej txheem ntawm Tuam Tshoj txoj kev lag luam kev hloov kho. .

Tam sim no, nyob rau hauv lub downstream tantalum capacitor kev lag luam, qhov kev thov rau cov tub rog kev txhawb nqa cov cuab yeej tseem nyob ruaj khov, tab sis tsis muaj kev cuam tshuam rau pej xeem siv nyob rau hauv xyoo tas los no. Ib qho ntawm cov laj thawj tseem ceeb yog cov tuam txhab lag luam thoob ntiaj teb tsis siv cov khoom siv hauv tsev hauv cov khoom tsim. Qhov tsis muaj cov qauv sib xws ua rau nws nyuaj rau kev lag luam hauv tsev capacitor nkag mus rau hauv kev lag luam thoob ntiaj teb.
