Tsis tas li ntawd, sodium hydrosulfide muaj nyob rau hauv qis dua, xws li 10, 20, thiab 30 ppm, catering rau cov kev kho mob tshwj xeeb.
Hauv kev lag luam tawv, sodium hydrosulfide plays lub luag haujlwm tseem ceeb hauv cov txheej txheem tsis muaj plaub hau. Nws pab tshem tawm cov plaub hau los ntawm cov tsiaj hides, ua rau nws yog ib qho tseem ceeb tivthaiv nyob rau hauv tawv ntau lawm. Kev ua tau zoo ntawm sodium hydrosulfide hauv daim ntawv thov no yog cov ntaub ntawv zoo, thiab nws siv tau txais kev txhawb nqa los ntawm cov ntaub ntawv kev nyab xeeb (MSDS) uas qhia txog kev tuav thiab kev ceev faj txog kev nyab xeeb.
Ntxiv mus, sodium hydrosulfide ua hauj lwm pab raws li ib tug dye auxiliary nyob rau hauv textile manufacturing. Nws pab nyob rau hauv cov txheej txheem dyeing, txhim kho xim uptake thiab kom ntseeg tau tias vibrant, ntev-ntev tau. Qhov kev ua tau zoo no ua rau sodium hydrosulfide ib qho khoom muaj nqis thoob plaws ntau qhov chaw.
Raws li peb txuas ntxiv xa tawm sodium hydrosulfide mus rau ntau lub khw African, peb tseem cog lus los muab cov khoom lag luam zoo uas ua tau raws li kev xav tau ntawm peb cov neeg siv khoom. Txawm hais tias kev kho dej, kev ua tawv tawv, lossis textile dyeing, sodium hydrosulfide ua pov thawj tias yog cov tshuaj tseem ceeb nrog ntau yam kev siv.
