Siab huv
Sodium tsim 99% min muaj kev coj dawb huv txog li 99% thiab tsawg heev impurities {2 2}}

Ntau yam ntawm cov ntawv thov
Sodium tsim 99% min% tuaj yeem siv tau dav hauv kev lag luam tawv (raws li cov tshuaj tiv thaiv kev txo qis, phag drilling

Muaj peb txoj kev tseem ceeb rau kev tsim cov khoom noj qab haus huv: carbon monoxide synthesis cov qauv thiab neopentyl glycoling xyaum .

1) {{{{1} Cov kauj ruam yog raws li nram no: {5}) thiab siab dua sodium acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid acid yog: co + Naoh → hcoona
Cov txheej txheem no siv coke raws li cov khoom siv raw, thiab ua kom muaj plua plav, sib cais, thiab ziab, thiab ziab, thiab ziab, thiab ziab, thiab ziab, thiab ziab, thiab ziab, thiab ziab, thiab qhuav kom tau cov khoom sodium
Cov txiaj ntsig: cov sodium tsim los ntawm cov txheej txheem no muaj cov ntsiab lus ntau, uas haum rau cov tshuaj ntxiv, kev tuav pov hwm cov hmoov, thiab lwm yam}

2) {{{{. Cov lus piav qhia txheej txheem yog raws li hauv qab no:
- Cov Cokeification: tus coke raug xa mus rau hauv cov roj tawg thiab tsis muaj pa roj xws li carbon monoxide thiab cov pa roj carbon monoxide thiab nitrogen .
- Purification: Cov roj sib xyaw ua ntej dhau los ntawm Cyclone plua plav daws teeb meem kom tshem tawm cov khoom siv roj av, tom qab ntawd nkag mus rau cov khoom siv alkalebred precipitator .
- Kev siv hluav taws xob: cov roj ua kom huv tau nias rau 2 {.} 0 ~ 2.2mpa kom tau txais cov pa roj carbon monoxide
- hluavtaws: carbon monoxide roj reacts nrog sodium recharod ua kom muaj kev daws teeb meem, thiab roj av sib xyaw ua ke, thiab cov roj tov sib xyaw ua ke rau cov pa hluav taws xob, thiab cov roj tov sib xyaw ua ke rau kev tawm .
- Kev sib cais evapation: cov sodium tsim kev daws teeb meem yog cov ntsiab lus ntawm 70%} Tom qab 5% los ntawm 5.
- ntim khoom: cov sodium tsim kev daws teeb meem yog centrifuged thiab qhuav, thiab tom qab ntawd ntim .

Siv cov txheej txheem alkaline hauv cov txheej txheem ntau lawm ntawm cov khoom siv roj hmab ua haujlwm yog xim lim dej yog xim lim thiab tawv nqaij thiab tawv nqaij tsis-corrosiveness .
Cov txiaj ntsig: xim dawb thiab muaj txiaj ntsig siab

Nyob rau hauv cov txheej txheem npaj ntawm neopentyl glycol, formaldehyde reacent nrog cov khoom noj khoom haus neopentyl glycole tsim nrog cov ntsiab lus ntawm txog 98%.
Cov txiaj ntsig: xim dawb, muaj kev huv siab, tsis muaj Cegaking, ntau cov kev siv
