Nkag siab Sodium Hydrosulfide: Siv, Cia thiab Kev Nyab Xeeb
Sodium Hydrosulfide, feem ntau hu uaNAHS(UN 2949), yog qhov sib xyaw ua ke uas muaj ntau yam kev siv thoob plaws kev lag luam. Muaj nyob rau hauv ntau qhov ntau, xws li 10/20/30ppm, Sodium Hydrosulfide feem ntau yog siv hauv textile, ntawv thiab mining industries, ua lub luag haujlwm tseem ceeb hauv cov txheej txheem xws li dyeing, bleaching thiab mineral extraction.
Ib qho kev siv tseem ceeb ntawm sodium hydrosulfide yog nyob rau hauv kev tsim cov sodium sulfide, tshwj xeeb tshaj yog nyob rau hauv zus tau tej cov pulp thiab ntawv. Nws ua raws li tus neeg sawv cev txo qis, pab txhawm rau txhawm rau lignin hauv ntoo, uas yog qhov tseem ceeb rau kev tsim cov ntawv zoo. Tsis tas li ntawd, hauv kev lag luam textile, sodium hydrosulfide yog siv rau nws cov khoom bleaching, zoo tshem tawm cov xim tsis xav tau ntawm cov ntaub.
Nyob rau hauv cov nqe lus ntawm kev cia, sodium hydrosulfide yuav tsum tau ua tib zoo saib xyuas vim nws reactive xwm. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, kom deb ntawm cov khoom tsis sib xws xws li acids thiab oxidants. Cov thawv ntim khoom yuav tsum raug kaw kom tiv thaiv kom tsis txhob nqus dej noo, vim tias sodium hydrosulfide reacts nrog dej kom tso cov pa roj hydrogen sulfide, uas ua rau muaj kev phom sij rau kev noj qab haus huv.
Nws yog ib qho tseem ceeb rau txhua tus neeg ua haujlwm nrog sodium hydrosulfide hydrate lossis sodium sulfide nonahydrate kom ua raws li cov txheej txheem kev nyab xeeb, suav nrog kev hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE), xws li hnab looj tes thiab tsom iav. Kev ua haujlwm kom raug thiab kev cob qhia cov txheej txheem xwm txheej ceev kuj tseem ceeb los xyuas kom muaj chaw ua haujlwm nyab xeeb.
Hauv cov ntsiab lus, sodium hydrosulfide yog ib qho tshuaj tseem ceeb nrog ntau yam kev siv, tab sis nws yuav tsum tau ceev faj tuav thiab khaws cia kom txo tau kev pheej hmoo. Kev nkag siab txog nws txoj kev siv thiab kev ntsuas kev nyab xeeb yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog qhov sib xyaw no hauv qhov chaw tsim khoom.
