Sodium hydrogen sulfide (NaHS) thiab sodium sulfide nonahydrateyog cov tshuaj tseem ceeb uas ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov tshuaj zas, tawv ua thiab chiv. Cov tebchaw no, uas muaj UN tus lej ntawm 2949, yog qhov tseem ceeb tsis yog rau lawv cov khoom siv tshuaj lom neeg nkaus xwb tab sis kuj rau lawv cov ntawv thov ntau.
Hauv kev lag luam dyeing, sodium hydrogen sulfide yog siv nyob rau hauv cov synthesis ntawm organic intermediates thiab kev npaj ntawm ntau yam sulfur dyes. Cov dyes paub txog lawv cov xim vibrant thiab zoo heev ceev ceev, ua rau lawv thawj xaiv ntawm textile manufacturers. Lub peev xwm ntawm NaHS los ua tus txo tus neeg sawv cev txhim kho cov txheej txheem dyeing, kom ntseeg tau tias cov xim tsis tsuas yog vibrant, tab sis kuj ntev.
Kev lag luam tawv kuj tau txais txiaj ntsig zoo los ntawm sodium sulfide. Nws yog dav siv rau dehairing thiab tanning nyoos hides thiab tawv, hloov mus rau hauv cov tawv muag muag. Tsis tas li ntawd, NaHS ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kho dej khib nyiab, pab kom tsis txhob muaj cov khoom tsis zoo thiab txhim kho cov dej khib nyiab zoo ua ntej nws tawm mus rau ib puag ncig.
Tsis tas li ntawd, nyob rau hauv cov tshuaj chiv, sodium sulfide yog siv los tshem tawm monomer sulfur nyob rau hauv activated carbon desulfurizers. Cov txheej txheem no tseem ceeb heev rau kev tswj xyuas qhov ua tau zoo ntawm desulfurization system. Tsis tas li ntawd, NaHS tseem tuaj yeem siv los ua cov khoom lag luam ib nrab los tsim cov ammonium sulfide thiab cov tshuaj tua kab ethyl mercaptan, ob qho tib si tseem ceeb rau kev ua liaj ua teb.
Raws li cov ntsiab lus, sodium hydrogen sulfide thiab sodium sulfide nonahydrate yog qhov tseem ceeb hauv kev lag luam ntau yam thiab pab txhawb rau kev tsim cov dyes, tawv thiab chiv. Lawv versatility thiab kev ua tau zoo ua rau lawv cov neeg tseem ceeb hauv kev txhim kho cov khoom zoo thiab kev ruaj ntseg ib puag ncig.
