Yuav luv nqi Hoobkas High Purity Calcium Hlau ua nyob rau hauv Suav teb. Harvest Enterprise yog High Purity Calcium Hlau chaw tsim tshuaj paus thiab cov muag khoom nyob rau hauv Suav teb.Calcium Hlau lub hom phiaj tseem ceeb ntawm cov hlau calcium yog ua rau cov hlau calcium uas, thiab tom qab ntawd ua cov calcium hlau hlau los yog cov calcium hlau ntshiab, uas yog thaum kawg siv rau hauv refining hlau thiab hlau. Nws lub luag hauj lwm yog desulfurize thiab deoxidize thiab ua kom lub fluidity ntawm molten steel thiab txhawb kev nce ceev ntawm inclusions nyob rau hauv molten steel, feem ntau yog siv rau zus tau tej cov high-zoo steel.metallic calcium yog siv raws li ib tug dehydrating neeg sawv cev nyob rau hauv ua waterfree cawv thiab siv los ua desulfurizert hauv kev lag luam roj av, siv los deoxidize lossis desulfurize hauv kev lag luam metallurgical.Txawm li cas los xij, calcium compounds muaj kev siv dav heev, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho kev lag luam.
Yuav luv nqi High Purity Calcium Metal Free Sample ua nyob rau hauv Suav teb. Harvest Enterprise yog High Purity Calcium Hlau chaw tsim tshuaj paus thiab cov muag khoom nyob rau hauv Suav teb.
Part 1: Yuav Ua Li Cas
1. Calcining marble (CaCO3), feem ntau hu ua calcined dawb, rau hauv txiv qaub ceev (CaO);
2. Ceev nrooj sib tov quicklime (CaO) nrog txhuas hmoov (AL) thiab siv lub pob xovxwm tshuab ua cov pob tiaj tiaj nrog qhov ntev li ntawm 4 cm;
3. Muab lub npas ca rau hauv lub tank txo nrog qhov kub ntawm 1200 degrees, thiab tom qab ntawd tshem tawm lub tank txo;
4. Cov hmoov txhuas thiab cov kua nplaum nrawm tau hloov pauv cov tshuaj tiv thaiv nyob rau hauv lub tshuab nqus tsev thiab kub kub kom tsim tau alumina thiab hlau calcium chav;
5. Cov hlau calcium vapor condenses nyob rau hauv cov dej-txias seem ntawm lub tank txo kom tsim cov hlau calcium uas muaju;
6. Tom qab txias, cov hlau calcium uas muaju tuaj yeem ua tiav rau hauv cov khoom siv hlau calcium uas yuav tsum tau ua, xws li hlau calcium particles thiab hlau calcium hmoov.
Part 2: Yuav Tau Li Cas
Feem ntau, muaj peb txoj hauv kev kom tau txais High Purity Calcium Hlau. Txoj kev txo qis, txoj kev electrolytic thiab calcium refining
1. Txoj kev txo qis yog txoj hauv kev tseem ceeb rau kev tsim cov hlau calcium. Feem ntau, limestone yog siv los ua cov khoom siv raw, calcined rau hauv calcium oxide, thiab txhuas hmoov yog siv los ua tus neeg saib xyuas. Cov calcined crushed calcium oxide thiab txhuas hmoov (txo tus neeg sawv cev) yog sib tov tusyees nyob rau hauv ib tug tej yam kev faib ua feem, nias rau hauv ib tug thaiv, thiab reacted nyob rau hauv 0.01 nqus tsev vacuum thiab 1050-1200 âº█ kub los tsim calcium vapor thiab calcium aluminate (alumina), txo calcium vapor crystallizes ntawm 750-400 ° C.The crystallized calcium yog melted nyob rau hauv kev tiv thaiv ntawm argon kom tau ib tug ntom calcium ingot. Tus nqi rov qab ntawm calcium uas tsim los ntawm txoj kev txo qis feem ntau yog li 60%.
2. Txoj kev ua ntej calcium electrolysis yog ib txoj kev tiv tauj. Nyob rau hauv txoj kev no, cov khoom siv raw khoom yog loj, solubility ntawm metallic calcium nyob rau hauv cov electrolyte yog siab, tam sim no efficiency yog tsawg, thiab cov khoom tsis zoo (kwv yees li 1% ntawm chlorine), thiab lwm yam. Los txhim kho cov shortcomings, tom qab ntawd. Txoj kev tiv tauj yog txhim kho rau cov kua cathode txoj kev electrolysis.
3. Calcium refining: High-purity calcium tuaj yeem tau tom qab muaj calcium ntxiv los ntawm lub tshuab nqus tsev distillation. Feem ntau, qhov kub distillation yog tswj ntawm 780-820 ° C, thiab lub tshuab nqus tsev kawm ntawv yog 1 × 10-4. Kev kho Distillation tsis tshua muaj txiaj ntsig hauv purifying chloride hauv calcium. Nitrogen tebchaw tuaj yeem muab ntxiv hauv qab qhov ntsuas kub distillation los tsim cov ntsev ob. Los ntawm kev ntxiv nitrides thiab purifying los ntawm lub tshuab nqus tsev distillation, cov sum ntawm impurity ntsiab chlorine, manganese, tooj liab, hlau, silicon, txhuas, npib tsib xee, thiab lwm yam nyob rau hauv calcium yuav txo tau rau 1000-100ppm, uas yog, 99.9% -99.99% siab purity calcium hlau.
