Sodium hydrosulfide yog siv nyob rau hauv kev lag luam dyeing raws li ib tug pab rau synthesizing organic intermediates thiab npaj sulfur dyes. Kev lag luam tanning yog siv rau dehairing thiab tanning ntawm hides thiab kev kho dej khib nyiab. Kev lag luam chiv yog siv los tshem tawm cov monomer sulfur nyob rau hauv lub tshuab txais carbon desulfurizer. Nws yog cov khoom siv raw rau kev tsim cov khoom lag luam ib nrab ntawm ammonium sulfide thiab tshuaj tua kab ethanethiol. Kev lag luam mining yog siv ntau heev rau kev siv tooj liab. Nws yog siv rau sulfite dyeing nyob rau hauv zus tau tej cov neeg ua fibers.
Nyob rau hauv lub ntiaj teb no kev ua lag luam, sodium hydrosulfide yog tsuas yog siv nyob rau hauv kev lag luam xws li ntxhia ua, tshuaj tua kab, dyes, tawv ntau lawm thiab organic synthesis. Hauv 2020, lub ntiaj teb sodium hydrosulfide kev lag luam loj yog 10.615 billion yuan, ib xyoos ib zaug nce ntawm 2.73%. Tam sim no, cov khoom tsim tawm txhua xyoo ntawm sodium hydrosulfide hauv Tebchaws Meskas yog 790,000 tons. Kev siv cov qauv ntawm sodium hydrosulfide hauv Tebchaws Meskas yog raws li hauv qab no: qhov kev thov rau sodium hydrosulfide rau kraft pulp suav txog li 40% ntawm tag nrho cov kev xav tau, tooj liab flotation suav txog li 31%, tshuaj thiab roj suav txog li 13%, thiab tawv ua lag luam suav txog li 31%. 10%, lwm tus (xws li cov txiv neej ua fibers thiab segphenol rau desulfurization) suav txog li 6%. Hauv xyoo 2016, kev lag luam loj ntawm European sodium hydrosulfide kev lag luam yog 620 lab yuan, thiab xyoo 2020 nws yog 745 lab yuan, ib xyoos ib zaug nce ntawm 3.94%. Hauv xyoo 2016, kev lag luam loj ntawm Nyiv kev lag luam sodium hydrosulfide yog 781 lab yuan, thiab xyoo 2020 nws yog 845 lab yuan, ib xyoos ib zaug nce ntawm 2.55%.
Txawm hais tias kuv lub teb chaws txoj kev lag luam sodium hydrosulfide pib lig, nws tau tsim sai heev thiab tau dhau los ua ib qho tseem ceeb hauv kev lag luam hauv kuv lub teb chaws kev lag luam. Sodium hydrosulfide kev lag luam occupies ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub teb chaws kev khwv nyiaj txiag. Sodium hydrosulfide kev lag luam tuaj yeem tsav txoj kev loj hlob ntawm kev ua liaj ua teb, kev lag luam textile, tawv kev lag luam thiab lwm yam kev lag luam; tsav scientific thiab technologies kev vam meej thiab lub teb chaws kev loj hlob; muab thiab nthuav txoj hauv kev ua haujlwm.
Raws li GB 23937-2009 industrial sodium hydrosulfide tus qauv, muaj sodium hydrosulfide yuav tsum ua raws li cov qauv hauv qab no:
Los ntawm qhov kawg ntawm xyoo 1960 mus txog rau nruab nrab-1990s, Tuam Tshoj txoj kev lag luam sodium hydrosulfide tau txhim kho thiab tsim kho tshiab ntawm cov cuab yeej tsim khoom, thev naus laus zis thiab cov khoom tshwj xeeb. Nyob rau xyoo 1990s, kev tsim cov sodium hydrosulfide tau tsim kom muaj kev siv tshuab ntau dua. Anhydrous sodium hydrosulfide thiab crystalline sodium hydrosulfide tau ua tiav tiav thiab nkag mus rau hauv ntau lawm. Ua ntej, nyob rau hauv cov txheej txheem ntawm sodium hydrosulfide nyob rau hauv kuv lub teb chaws, nws tau pom tias tus nqi qis ntawm cov qib tshwj xeeb thiab cov ntsiab lus hlau ntau dhau 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 zoo thiab cov khoom tsim tawm tau nce, thiab cov nqi kuj tau poob qis. Nyob rau tib lub sijhawm, nrog rau kuv lub teb chaws tseem ceeb rau kev tiv thaiv ib puag ncig, cov dej khib nyiab tsim los ntawm kev tsim cov sodium hydrosulfide kuj tau kho zoo.
Tam sim no, kuv lub teb chaws tau dhau los ua tus tsim khoom loj hauv ntiaj teb thiab cov neeg siv khoom ntawm sodium hydrosulfide. Raws li kev siv sodium hydrosulfide tau tsim tas li, nws qhov kev thov yav tom ntej yuav maj mam nthuav dav. Sodium hydrosulfide yog siv hauv kev lag luam dyeing los ua ke cov organic intermediates thiab ua tus neeg sawv cev pabcuam rau kev npaj cov sulfur dyes. Kev lag luam mining yog siv dav hauv kev siv tooj liab ore beneficiation, nyob rau hauv kev tsim cov txiv neej ua fibers rau sulfite dyeing, thiab lwm yam. rau kev kho dej khib nyiab. Kev hloov pauv thev naus laus zis tau ua cov txheej txheem tsim khoom ntawm sodium hydrosulfide ntau dua. Nrog rau txoj kev loj hlob ntawm ntau hom kev lag luam thiab kev sib tw hnyav zuj zus, kev ua haujlwm thev naus laus zis ntawm sodium hydrosulfide ntau lawm txo cov tswv yim ntau li ntau tau los tsim cov khoom zoo thiab ntau dua.
