Sodium Hydrosulfide yog siv nyob rau hauv qhov kev lag luam zas ua ib pab pawg ua ke thiab npaj cov txiv ntoo sulphic. Kev lag luam tanning yog siv rau kev ua haujlwm thiab tanning ntawm hides thiab rau cov dej khib nyiab kho. Kev lag luam chiv siv tau los tshem tawm cov monomer leej faj hauv cov pa roj carbon allulfurizer. Nws yog cov khoom siv raw rau kev tsim cov khoom semi-tiav cov khoom ntawm ammonium sulfide thiab tshuaj tua kab thiab tshuaj tua kab. Kev lag luam mining tau siv ntau rau cov neeg tau txais txiaj ntsig tooj liab. Nws yog siv rau cov sulfite Dyeing hauv kev tsim cov txiv neej-ua fibers.
Hauv kev ua lag luam thoob ntiaj teb, sodium hydrosulfide yog siv rau hauv kev lag luam xws li kev ua tshuaj tua kab, tshuaj tua kab, dyes, tev ntau lawm thiab cov organic synthesis. Hauv 2020, lub ntiaj teb sodium hydrosulfide kev ua lag luam loj yog 10.615 billion yuan, ib xyoos-nyob rau xyoo nce ntawm 2.73%. Tam sim no, cov zis txhua xyoo ntawm sodium hydrosulfide hauv Tebchaws Asmeskas yog 790,000 tons. Cov qauv kev siv cov qauv ntawm cov sodium hydrosulfide hauv Tebchaws Meskas yog li hauv Kraft rau ntawm cov ntawv qhia txog 40%, tooj rau cov khoom siv thiab cov tshuaj tua tsiaj thiab cov roj ntsha rau li 13%, thiab tawv ua nyiaj rau txog li ntawm 31%. 10%, lwm tus (suav nrog tus txiv neej ua fibers thiab segphenol rau desulfurization) tus account rau txog 6%. Xyoo 2016, kev ua lag luam loj ntawm European Sodium Hydr Xyoo 2016, kev ua lag luam loj ntawm Nyij Pooj Sodium Hydrosulfide Kev Lag Luam yog 781 lab yuan, thiab hauv 2045 lab yuan, ib xyoos-nyob rau xyoo 2.55%.
Txawm hais tias kuv lub teb chaws sodium hydrosulfide pib lig, nws tau tsim kom sai thiab tau dhau los ua kev lag luam tseem ceeb ntawm kuv lub tebchaws. Sodium Hydrosulfide kev lag luam ua haujlwm ntawm thaj chaw pivotal hauv kev lag luam hauv tebchaws. Sodium hydrosulfide kev lag luam tuaj yeem tsav kev loj hlob ntawm kev ua liaj ua teb, textile kev lag luam, Tawv Kev Lag Luam thiab Lwm Yam Kev Lag Luam; tsav tsheb science thiab thev naus laus zis thiab kev lag luam hauv tebchaws; Qhia thiab nthuav tawm txoj haujlwm.
Raws li GB 23937-2009 muaj sodium hydrosulfide tus qauv, kev ua si sodium hydrosulfide yuav tsum ua kom tau raws li cov qauv hauv qab no:
Txij thaum xaus ntawm 1960s mus rau nruab nrab-1990s, Tuam Tshoj cov sodium hydrosulfide kev lag luam tau zoo heev cov khoom siv, thev naus laus zis thiab cov khoom lag luam tshwj xeeb. Nyob rau hauv lub xyoo 1990, kev tsim cov sodium hydrosulfide tau tsim rau qib siab dua thev naus laus zis. Anhydrous sodium hydroselfide thiab crystalline sodium hydrosulfide tau ua tiav kev tsim thiab nkag mus rau hauv ntau lawm. Ua ntej, hauv cov txheej txheem ntau lawm ntawm sodium hydrosulfide hauv kuv lub teb chaws, nws tau pom tias cov khoom siv hlau tshwj xeeb yog cov teeb meem tseem ceeb hauv kev tsim khoom. Los ntawm kev txhim kho txuas ntxiv ntawm cov txheej txheem ntau lawm, cov khoom lag luam zoo thiab tso zis tau nce, thiab cov nqi kuj tau poob qis. Nyob rau tib lub sijhawm, nrog kuv lub teb chaws tseem ceeb ntawm kev tiv thaiv ib puag ncig, cov khib nyiab tsim los ntawm kev tsim cov sodium hydrosulfide kuj tau kho tau zoo.
Tam sim no, kuv lub tebchaws tau dhau los ua lub ntiaj teb tsim nyog thiab cov neeg siv khoom ntawm sodium hydrosulfide. Raws li kev siv sodium hydrosulfide tau tsim txuas ntxiv, nws qhov kev thov yav tom ntej yuav maj mam nthuav. Sodium Hydrosulfide siv rau hauv kev zas xim rau cov khoom siv cov organic thiab raws li tus neeg sawv cev ntawm cov txiv lws suav. Lub mining kev lag luam tau siv dav hauv tooj liab One cov khoom lag luam rau cov khoom siv uas ua tiav rau cov khoom siv ntawm amonmium thiab tshuaj tua kab ethyl mercaptan, thiab tseem siv rau kev kho dej khib nyiab. Kev hloov pauv thev naus laus zis tau ua tiav cov txheej txheem ntau lawm ntawm cov sodium hydrosulfide ntau paub tab. Nrog rau kev txhim kho ntawm ntau cov lag luam cov ntaub ntawv thiab cov kev sib tw ua rau muaj kev sib tw ntau ntxiv, cov kev ua kom nruj ntawm cov khoom siv hluav taws xob ntau li ntau tau los ua cov khoom lag luam zoo thiab ntau yam khoom lag luam.
