Sodium hydrosulfide, nrog rau cov tshuaj formula NaHS, yog ib qho kev sib xyaw uas tau txais kev pom zoo nyob rau hauv ntau yam kev lag luam. Peb lub tuam txhab tshwj xeeb hauv kev xa cov hnab ntawm sodium hydrosulfide mus rau African lub teb chaws, kom ntseeg tau tias kev lag luam muaj kev nkag mus rau cov tshuaj tseem ceeb no.
Ib qho kev siv tseem ceeb ntawm sodium hydrosulfide yog hauv kev kho dej. Nws ua raws li tus neeg sawv cev txo qis, tshem tawm cov hlau hnyav thiab lwm yam kab mob ntawm cov dej khib nyiab. Cov tshuaj muaj nyob rau hauv ntau qhov ntau ntau, suav nrog kev siv dav 70% NaHS cov tshuaj, uas tshwj xeeb tshaj yog siv los kho cov dej khib nyiab. Tsis tas li ntawd, sodium hydrosulfide muaj nyob rau hauv qis dua, xws li 10, 20 thiab 30 ppm, kom tau raws li kev kho mob tshwj xeeb.
Hauv kev lag luam tawv, sodium hydrosulfide plays lub luag haujlwm tseem ceeb hauv cov txheej txheem tshem tawm cov plaub hau. Nws pab tshem tawm cov tsiaj plaub, ua rau nws yog ib feem tseem ceeb ntawm cov tawv nqaij. Kev ua tau zoo ntawm sodium hydrosulfide hauv daim ntawv thov no tau sau tseg zoo, thiab nws siv tau txais kev txhawb nqa los ntawm Daim Ntawv Qhia Txog Kev Nyab Xeeb (MSDS) qhia txog kev tuav thiab kev ceev faj txog kev nyab xeeb.
Tsis tas li ntawd, sodium hydrosulfide yog siv los ua cov khoom siv zas xim hauv kev tsim textile. Nws pab cov txheej txheem dyeing, txhim kho xim xim thiab ua kom cov txiaj ntsig zoo, kav ntev. Qhov kev ua tau zoo no ua rau sodium hydrosulfide ib qho khoom muaj txiaj ntsig thoob plaws ntau qhov kev lag luam.
Raws li peb txuas ntxiv xa tawm sodium hydrosulfide mus rau ntau lub khw hauv Africa, peb tseem cog lus los muab cov khoom lag luam zoo uas ua tau raws li cov kev xav tau ntawm peb cov neeg siv khoom. Txawm hais tias hauv kev kho dej, kev ua tawv tawv lossis textile dyeing, sodium hydrosulfide tau ua pov thawj tias yog cov tshuaj tseem ceeb nrog ntau yam kev siv.
